Yea so dell was super lame with not including hdmi/usb on the device itself, there's PLENTY of room to fit the connectors comfortably.
If it wasnt for the fact that the s10 uses a higher voltage to charge, everything done on the new connector could be accomplished on the s5/s7 pdmi-like connector. Even then the charging part is unnesscerry, as all other 10.1" tabs can charge fine though high-capacity usb chargers.
It features a HDMI connector, a USB-A female port, and a dock connector pass though to charge. It costs ¥299, which is approx $47 USD, which is really expensive for something that coulda been built into the device. But I assume most buyers knew this beforehand before buying.
Honeycomb should fully support HDMI/USB out of the box, so there shouldnt be anything to configure. Hopefully it will operate without requiring external power, which is almost forgivable since if you're going to attach it to a tv one extra box wont be a huge deal.
I am considering buying one myself since I'm in it for the long haul, but it's hard to overlook how lame dell was with this. I cant offer much advice to anyone else interested in importing, I'm going to go though my friend same as when my s10 was imported.
I do not believe there are any other accessories planned, the only thing missing vs the pdmi-like connector on the s5/7 is line out, which the s10 may not even support.
A lot of this criticism is also valid for the s7 though, it requires the hdmi dock to do anything, even though it could have been fitted with a microhdmi connector or usb host connector. The multimedia dock's launch MSRP was about $50 also, so they're both on par with pricing of additional connectivity.

I think that the S7 also provides a higher charge than normal USB. EDIT: That is why one cannot use it and charge from a computer. I think the S7 charger is 2mA.
The s7 can charge from [email protected] 500mA-2000mA, though only meaningfully at 1000-2000mA, or 2.5-10W.
the s10 charges at 19v @ 1580mA or 30W.
I've seen the s7 'charge' from 500mA while the screen is off, it just takes 10 or so hours to do so

Sorry I'm getting a friend to have one brought back on carry-on, they'll be leaving china in a couple days and it simply wouldnt be possible to order an extra before they depart.
Just as much, bringing multiples might look suspicious, but a single can easily be explained away.
If the timing wasnt so perfect I really dont know when i'd be able to get mine myself

Ok. Thanks. I will try to find some other way. Only wish Dell could have designed the adapter without the short cable like this...

The dell one has 2 ports and a passthough, it would really work out unless you wanted to get 2 seperate ones.
Personally it seems about right the way it is since it makes a good docking station setup if you get a good stand. If it was vertically down it'd be pretty difficult to have it mounted upright unless you got a very tall stand

Good point. Hope you will do a review once yours arrived. Cheers
Just recieved mine today, it's pretty great (if you ignore the fact it should have been built into the s10.
It's smaller then the picture implies, it's only slightly wider then the dock connector itself. It adds very little bulk to your kit if you carry it (in a bag or so) with your s10
W1orks exactly like you'd expect, the s10 supports usb hubs too.
Currently typing this on my tv with my s10 hooked up to it, have a usb keyboard and mouse and am currently charging my s5 off the s10 which itself is also charging off the wall.
Dell could easily make a transformer type dock for the s10 if they were inclined to. The fact that all the ports are on the bottom middle makes it extremely easy to hack together.
Only issue is that the charger is 19V which is a lot to ask from a battery.
Mini Review
As previously stated, the available ports on it are:
HDMI out
USB in
Power passthrough
HDMI Out
Works just as expected on any tegra2 device(?). It mirrors everything you see on the screen and shows it on the tv. You cant turn the tab screen off without losing your picture, but this is a limitation of the t2 itself and not the s10. (exact same thing happens on the s7)
Unfortunately some apps are not single touch friendly, such as the maps app on HC devices, you must use the screen to zoom in and out, but this is a limitation of apps and not related.
USB in
Works pretty great, plugged in a usb hub and a usb keyboard and mouse and they all worked fine. Even plugged in my S5 to charge and it works, though it's very slow as it's very underpowered. (not really surprising)
I put my s5 in usb mode and the s10 wouldnt mount. Afterwards it apparently completely corrupted my card[!]. Fortunately it had nothing irreplacable, but I dont know yet if this was a one off thing or consistant.
Power passthrough
Does exactly what it looks like it does, lets you also charge it while in use.
Overall
The box itself is pretty small, it's only slightly wider then the dock connector. The press shots dont really do it justice to how small it feels. The thing is also very light as it seems to not actually contain anything, it's merely a pass though connector.
Conclusion:
Pros:
Small
Light
Supports usb hubs
Easy way to organize cables/acts as a docking station
Cons:
Bit pricy for just a dumb passthough box
Corrupted my memory card[!](?)
Should be bundled with all new s10s and not seperate
Random trivia: PEGATRON (the manufacturer of the S10 for dell) was spun off from asustek along with asus. The Transformer was made by asus. The S10 essentially has capability of it's own version of a transformer dock. The dock connector is in the right location and exposes the needed pins for a transformer type dock to be made, were it not for the way the s10 charges. Unfortunately it is unlikely for a transformer type dock to ever be made.

I've searched and never seen an actual 'buyable' product linked on the forums so if this is a dup, I apologize.
Anyone try one of these and see if you can have your Nexus in host mode and charge at the same time?
Is the only option for the female Micro USB port to bring more charge to a usb device plugged in and not to bring charge
to the Nexus itself?
Two scenarios would make this ideal for me:
1.) using my usb xbox controller to play games yet still keeping my tablet charged
2.) using a usb thumb drive to play a movie while still keeping my table charged
I think this would be pretty cool if it worked but I don't know the technical details on if it can be done with our Nexus 7's:

Looks like it's meant for providing power to the USB device you connect (e.g.. external hard drive) instead of to the Nexus7...
The eBay description says it provides charging the the micro-USB port. Only way to know is to buy it and try it out

OTG and Charging is mutually exclusive, the OTG cable triggers the USB controller to send power out to a device, not receive power.
the pogo docks on the bottom of the device are also impossible to charge from as the nexus 7 has only been given one charging circuit, and that is the same one that OTG disables.
The only way to achieve something like this would be a physical battery hack where you splice in a charging circuit direct to the battery, without frying the phone maybe some unidirectional resistors, so that it can be simultaneously charged whilst powering the device.
I'm 99% certain of this information, and this is not to say someone might hack a kernel together one day
you might be able to install one of them batteries you can just set it on a charging pad and it will charge

I have a ZAGG battery pack I'm planning on trying this with and I will report back I also have that same pad and I can get a fairly cheap charger to place on the matt as you say. Either way that wouldn't be very convenient, but I'll check it out

Wrong. https://github.com/teamhacksung/and...mmit/4c1c965b168bc4488ef66889e1c8933bc1b3de46 for an example on Galaxy S2/Note
As to whether the adapter linked is a proper OTG ACA (they're VERY hard to find) and whether the grouper supports OTG ACA is unknown. It's something a kernel developer can probably implement.
Thanks Entropy512, I can see it working on other devices, that gives me hope... I might rig something up myself now, I've wanted to take a cheap usb keyboard plastic leather cover, and build in an extra battery, card reader and usb hub, now this might be theoretically possible

I can confirm that simply splicing a standard OTG cable into the port and plugging in a power cord will not work. I thought I'd utilize the empty socket from where the rear camera was supposed to go, and try to fit the OTG-to-microSD set-up inside of the Nexus. I bought a salvaged USB/headphone port from a damaged Nexus off of Ebay for $1 and the smallest microSD adapter I could find. With the use of a ribbon cable from an old laptop, some trimming, and some REALLY careful soldering I was able to make it work... sorta. Stickmount sees the card and everything runs great, until you plug in a power cord. Then, it disables the microSD adapter, and even though Stickmount says it's there, no files are visible. Also, the Nexus won't charge with this arrangement.
It might work with a different set up, but simply mimicking the OTG cable will not allow a Stickmounted volume and when the charger is plugged in.
(BTW - To make everything fit, I had to use a Dremel to grind away some of the mid-frame area around the rear camera space. It's a tight fit, but keep in mind that until you have a spare mid-frame, like I do, you'll obviously void your warranty.)

Same here, only I went a step further and added a 36k resistor from the ID line to ground and that didn't do anything either.
Hope all your work ends in success.

Coming Internally Soon to a Nexus 7 near you...
This is the picture of the device EXTERNALLY;
What we are now trying to accomplish is internally setting this up. I ordered a microSD reb mount connector that will allow a ground to be present once the memory card is inserted. This will allow me to utilize the points for SWITCH and enable disable OTG mode. I also ordered a 5v step-up board to test another theory I would like to put in place, in short, not utilizing OTG mode at all.
haha, as if. i was just saying this to a friend today it would be better to do this instead of using a cable. good job.

If this can be installed internally, this would prove to be a great solution to the OTG issue... Looking forward to watching progress :good:
I assume you're aware that previous internal OTG's have interrupted USB communications, have you resolved that part (I assume being able to switch the OTG part in/out as necessary)?
Oh, interesting... Get this done, or even a real nice compact USB dongle and I'll get a n7 and buy it from you!

Yes I am aware that this is a huge issue for anything data related. I also noticed that most diagrams for D+ and D- are backwards which might stop some progress, which it did in my case. See attached image for CORRECT wiring of a USB Port. I blew out at least 3 microSD Cards already but thats not a big deal to me. However the mouse and keyboard on a hub has been working flawlessly no matter how many times i switch back and forth. Seems like anything that needs to read FAT32 or NTFS is a big fail for me at this point. I think that is more a software problem then anything though.
I'd also like to add to others trying to complete something like this once the Sense switch is grounded 5V is provided out to the device to power it. If the sense switch isn't grounded then 5V is not being pushed only pulled to charge.
I wish you the very best of luck, as I have been researching this avidly for awhile and sketching out possible solutions in my head.
I hope you and other readers have seen the numerous similar threads on this topic. As I think you are aware, the chief problem relates to retaining the charging/peripheral functionality of the nexus while also permitting it to act as host to mice/drives/etc. Your microswitch is a simple and clean solution for this, although as you mention on youtube you can't do both at the same time. I guess that would be the holy grail. I'm afraid some of the hackers out there are in for a nasty surprise when they complete their mods and realize they can no longer charge their nexus. Your microswitch eliminates that nasty surprise.

Retaining the charging isn't going to work with OTG mode on considering the 5V is pushed out in OTG mode not pulled in. Its like a break light in a car, reversed polarities + & - when you hit the break when you have your parking headlights on. I don't know of a way at this time because of hardware limitations to make charging work while in OTG mode. Meaning to power the device and have a MicroSD card work all the time is not going to happen in my mind right now. I could try charging while my wiring is plugged in but I'm pretty certain I'll blow at least one thing out on the nexus board.
P.S - 30 AWG Kynar wire (wrapping wire) is the way to wire anything in this tight device not Cat5 wire.... :/
xboxexpert - Yes, we're in complete agreement. Simultaneous charging and hosting may be the mythical unicorn here, and I'm glad you (unlike some modders) recognize that before pulling out the dremel tool .
The best lead I have on the simultaneous thing would be to implement what the USB spec calls "Accessory Charger Adapter". See Chapter 6, and in particular Figure 6-2 from the specification:
www(dot)usb(dot)org/developers/devclass_docs/BCv1.2_070312.zip
Two problems with ACA, however. I can't for the life of me find a vendor who sells one of these dongles (although there seem to be a few IC's now incorporating the spec). Second I think you would need to physically break the data traces leading to the original micro-b receptacle (the easiest place might be on the ribbon cable). Otherwise you would have data collisions between the internal device and any pc/peripheral/otg device attached to the micro-b receptacle. To permit pc/peripherals/ or other data devices to mate with the nexus, you'd have to install a second micro-ab receptacle into the nexus housing. At the end of the day, the original usb port could be used for charging only, while the new micro-ab port could be used to automagically connect to both peripherals (mice, thumbdrives, etc via otg cable) and hosts (PCs).

In theory if you were to in fact break the trace and split the 5v line to do either or since the only difference is 5v polarity is pretty easy in its self. Fitting it all in the unit with a device that does just that for a all in one effect is quite the contrary. I am however actively building a dock (mock-up) to do just this. So as this thread stated completely internal for what we are trying to acquire, speaking about now, it may be imposable.
Then again if KERNEL Devs were able to detect when the power cable was inserted somehow and switch off or program a feature to defeat this...we would probably be talking a different story. I recall the Nook Color had OTG capabilities that were kernel unlocked down the road. I wonder if I took a stroll over there and did some digging looking into its development if there might be some light shed on this issue. Also if its not a problem now for the Nook Color what was fixed...
Rock on with the dock. I'll keep my eyes open for that thread I'm looking to build a gaming-oriented enclosure for my nexus, and if an external ACA solution can be found, I'll likely integrate that into my enclosure along with the joysticks, buttons, etc.
I too recall some progress with the nook color. IIRC the nook wasn't actually powering peripherals when in host mode, so the charging thing was a slightly different animal. I may be wrong on that.
I am going to remove the Sense wire to trip 5v through the port and instead test with external 5v power to the device. I wonder if the device powered externally will show in Stick Mount. If so I will tear this puppy apart tonight and pin out the entire board to find a solid 5v point. In theory I can as of now pin it to the red wire on the battery giving off 3.9v-4.0v but that would under power a hub but may power a sd card.
More progress tonight let me get back to work

There are a bunch of folks looking hard for a +5V pin other than from usb. It's actually not easy since the board is mostly 3.3V and batteries are in series at 7.4v.

Yes we need to find the 5v regulator that regulates the 5v that comes out of the USB port once Sense is triggered. Its somewhere close just need to cut the trace and trigger it for a 5v point.
Also Google LM2940CSX or LM2940CSX-5 is what we would need to down-step the 7.4v line a better option for what we want to achieve. Also looks like that regulator may be the PERFECT fit in where the back camera would go and perhaps solder it to the area for heat reduction.

where do you get 7.4v from when the leads from the battery are reading 3.7 and 1.7?
-unless you're adding the two 3.7v leads together to get 7.4v. In which case you'd need to sum the two leads before the 5v regulator drops the voltage to 5v. Unless that regulator can step up the voltage from 3.7 to 5v (haven't looked up the part #s yet)

Two cells, 3.7V each, in series. (sorry was unclear) At least that's what they're saying in the other threads I referenced earlier. I can't confirm or deny, just passing along info...
There are so many threads on car chargers that actually work for the Nexus 7 and yet none of them seem to have reliable answers. Maybe it works, maybe not. Does it do "AC charging"? Is the amperage high enough to keep it running while I use it? Do I have to short Data+ and Data-? Does it work with OEM or aftermarket cables? Is it expensive?
It's enough to make you just want to keep the Nexus in the house. So I'm here to help - just go buy this:

It's a 3.1A dual port car charger for $12.99 on Amazon with a full 5/5 review. I just got mine and it's well built, very sturdy (almost OEM quality) and has two USB ports, one for Apple devices "A" and one for non-Apple devices "NA". The "NA" port will charge the Nexus 7 and the "A" port will charge most other non-tablets, including the Galaxy Nexus. It works with the OEM Nexus 7 cable, a Monoprice cable and a Galaxy Nexus cable.
So that's it. Just go buy it and be happy. It will charge quickly if you leave the tablet off but will still charge it if you keep using it.
EDIT 2-11-13: This charger has been charging my Nexus 7 virtually every day (40 mins/day) for over 3 months now with no problems.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
For those of you wanting to know some more specifics, here they are. (You don't have to care, honest! Just go buy the thing.)
I did a test with my 7 starting at 40% battery. I did a "worst case scenario" of Wi-Fi on and connected, Bluetooth on, GPS on and using Google Navigation, Spotify streaming and the screen on at 100% brightness throughout charging. I powered the adapter off a variable DC power supply that shows current draw as well as voltage. I used 12.2 VDC to simulate a car's battery. Below is the relevant portion of the battery monitor graph.

It does indeed charge using the "NA" port with no modifications. The power supply showed an average current of 0.50A @ 12 VDC which once converted to 5 VDC is 1.22A not counting for the small loss in the DC-DC converter. It did get as high as 0.62A (1.51A @ 5VDC) but seemed to level out at 0.5A for the vast majority of charge time. (FYI I assume Watt's law applies here when stepping down voltage - feel free to correct me.)
I checked on the progress every 30 mins and here are the results:
00:00 - 40%
00:30 - 48% (+8%)
01:00 - 55% (+7%)
01:30 - 62% (+7%)
02:00 - 68% (+6%)
02:30 - 76% (+8%)
03:00 - 83% (+7%)
This is where I stopped. It seems to be very capable of providing a decent charge while under heavy use. At this point I turned everything off and waited another 30 mins and found it charged another 12% while "idle". At that rate it could charge from empty in around 4 hours. It would take around 7 hours to charge completely if being used heavily, but it's not just "maintaining" a charge or discharging slowly - it's actually gaining a charge.
So there you have it.

What about the "A" port makes it exclusive to Apple devices only? I own zero Apple devices, so would this dual USB charger effectively be... a single one for my uses?

I think the "A" port does not short the two data pins because Apple doesn't like that. Most Android phones don't seem to care either way though. My Galaxy Nexus works with it, I think a friend's SGS3 works as well. A reviewer notes the Kindle products worked as well. The thing to note is that charging non-Apple devices in the "A" port will only charge them at USB speed. Not perfect but it should do the trick.

If you are rooted and have a kernel setting to enable fast charge on USB, you should be able to use the "A" port for full power. Be sure to turn that feature off, though if you want to swap data with PC.

I tried this on computer USB and the notation in Battery Monitor Widget changed from USB plugged to AC plugged when connected to my computer. milliamps went from 479 to 875. Still will see what happens on various chargers. But to get 875mA from computer's USB port seems pretty darn good.
Thanks a lot for sharing this with us! seriously there are many car chargers than would never work due to low amp!!
Bought this same charger the other day. Arrived yesterday, so far so good! Excellent value for money :good:
Good Deal On Amazon
Thank you for pointing the way about car chargers that work. I have been impressed with this charger doing more than slowing down discharge. I can actually use the larger GPS of my N7 and charge my tethering GS3 at the same time. When purchasing this charger I was offered the 3.1a/15w AC charger for 20% off. It definitely charges like the OEM one. Very happy camper.
What cord are you using with this to charge the nexus?

Another Option
Hey guys - there is another option that is very high quality -
The Scosche ReVIVE II works very well with the nexus 7 (at the same time as a phone too) with the 2.1A charging port. The only catch I found was that I had to short out the data connections - but I did this with a USB extension cable.
Essentially all you do is cut a USB extension cable, reconnect the power wires and then join the two data wires on the device end. This, for someone who has done some soldering, is a super easy job and takes 5 minutes, as well as making sure you don't ruin a perfectly good micro-USB charger.
The reason for shorting the Data is that some devices wont charge to their full potential (ie. only to 500mA) if they dont have the data wires shorted because the device might be connected to a computer - which wouldn't handle the full 1/2A.
anywho, it's a fantastic, very high quality charger and well worth the price.

Charging Cord
I use either my OEM GS3 or N7 for the NA port. I have a Rocketfish USB charging cord when I have to use the A port. I purchased it from BestBuy a while ago, initially for my BB at the time.
This sounds great.
I have a iPod Nano 6th Gen that I keep plugged in all the time, and a USB cable for my Phone. I modified my existing one so my Galaxy Nexus reads it as AC and charges fast, but my N7 doesn't even see it.
The one posted in the OP sounds like it'd be perfect. I could use the A for my iPod and the NA for both my N7 and GN. Fortunately the N7 doesn't require car charging very often
Sadly, Amazon.ca doesn't sell the charger and Amazon.com won't ship to Canada. Has anyone found a good source for this charger in Canada?

Coming from a Nexus 4 I had gotten used to the wireless charging dock and I am looking for a similar solution. I think I might resort to some sort of DIY solution if no products are available by December. I was thinking about working with something like this as a base stand and then running another metal bar in the cradle with a permanently affixed usb type c cord. Alternatively if they have a type c cable thin enough maybe I would use something like this and just put it in the rubber part. Although I was hoping someone else here might have some better ideas
Lastly, I am also holding out hope that someone will find an easy mod for adding a wireless charging adapter to the phone that doesn't require us to sacrifice corded charging or use a case...I really just wish Project Ara would get here already...
Just got my LG Nexus 5X the other day and had the same problem locating a suitable dock with the USB Type C. After some digging, found this product on the American ebay. Go to ebay.com and paste in Search "KiDiGi Omni Charger Cradle Desktop Dock for Smartphone with Type-C Charging Port" - apologies as XDA won't allow me to post hyperlinks yet as still considered a noob.... I believe this dock is also sold in Australia.
This is luckily shipped from outside the USA, China actually, and for free which is mightily handy. I purchased the item as a Guest using my British home address and used my PayPal a/c to purchase for £16.82 GBP (there was no currency charge or commission fee as far as I can see). Hey presto!

You beat me to it. Here it is
Will that dock rapid charge being that is only 2.4A? It looks very nice, but I'd also like to retain the rapid charging. I know, I know, first world problems!
Does the model compatibility matter? I feel like they'll just ship a general one out for all models
Hopefully one of you who ordered it can do a review with pictures

It has a USB plug on the end to power it - so to me that says it doesnt have a charging unit and requires you to use one of your own. It is simply a USB-C connector in a stand.
Looks nice though. I might get one depending on other similar types I can find.

It draws too much energy from the PC, potentially damaging the USB interface (on the motherboard).

It's a passive device that doesn't draw power on it's own. The power draw you metered was what the phone was pulling based on it's supplied power. The USB ports on your machine will be fine and if any damage were to occur it would be to the phone (unlikely).

The dock is just a cable in essence, but it fails the usb-c specification, and according to Google engineer Benson Leung, cables like these should not be used at the risk of damaging the device it is plugged into, because it lacks the correct resistor.
The phone is safe as it regulates the current draw, but it's under the impression the source allows more draw than it's actually certified to produce.
As far as I know, the USB 2.0 ports on my computer weren't designed to allow 2.4 A of current draw. (The cable built into the dock however facilitates it.)
i just had my dock shipped, so I'll post a review with photos when I get it. Might be awhile, as it's shipping from China (and I'm looking forward to any reviews that you guys post).
I got a refund for this dock from Kidigi.

You said in your unedited post that it couldn't draw more than 0.5mA from a USB-A interface rated as such, yet I sit here and my dock is letting me draw 2.4A, yes it's quick charging, but it's drawing more than the PC wanted it to.

I decided not to go down that rabbit hole. You are incorrect in your post, but it's not my job to force knowledge down your throat.

Introduction
One can never have too many wall chargers; especially in a day and age where people own multiple devices or live in busy households with many cellphones users under the same roof. I am one of those people, so wall chargers with multiple ports often come in handy. There are plenty on the market, but which one is the right choice? Also, I'm not a professional photographer, so some of the pictures will be less than fantastic, especially when you consider the Nexus 5X I used sucks at close-ups for some odd reason. Anyways, lets dive into the Tronsmart 33W Dual USB wall charger.
Disclaimer: I received the reviewed products from Tronsmart in exchange for this review. I have no financial stake or affiliation with this company. I've actually never even owned a Tronsmart product before. No bias exists here.
Details
Device: Tronsmart W2PTE Dual USB Quick Charger
Price: $21.99 (at the time of this review)
USB-A Output: 5V/3A(MAX)
USB-C Output: 3.6V-6.5V/3.0A,6.5V-9V/2.0A,9V-12V/1.5A(MAX)
Initial Impressions
Along with the charger, I received boxes of Black and White USB-C and USB-A to USB-C cables (four cables total). This review will not focus on the performance of the cables, as they have already been reviewed here. They do, however, adhere to the USB-C standard.
The packaging is pretty standard. They're cables and chargers, so nothing fancy is really required here. I did notice, almost immediately, the USB 2.0 logo. I'm a little disappointed that the cables are not USB 3.0 but we're really treading into nitpicking territory here. My Nexus 5X isn't USB 3.0 capable but my future devices down the road might be.

My first impressions of the charger are good. It's made of a mixture of textured and gloss plastic, the design itself is quite attractive. There are no visible seems or sharp edges in the plastic. Additionally, it has a nice heft to it, sometimes indicative of quality. The swiveling mechanism moves with an authoritative "snap", inspiring further confidence in the build quality of the product.
As mentioned previously, I received two USB-A to USB-C cables, one black and one white, and two USB-C cables in the same color arrangement. The cables are terrific. The first thing I noticed was that the cables are a bit thinner than the Choetech cables I have (same gauge as the cable that came with the phone), but are far more flexible. The flexibility is nice when charging the phone on my desk so I don't have to bend and manipulate the cable to get it in a state where it's not constantly tugging on my phone. With the less flexible Choetech cable, I felt that sometimes the cable with putting a lot of stress on the charging port of the phone. I don't have this concern with the Tronsmart cables. This is also great for travelling where I can easily coil them up and throw them in a bag without having to twisty-tie them together. The ends of the cables are also a bit nicer as well. The USB-C ends having a sloped, ergonomic shape that fits my fingers quite well.
Design and Features
The charger sits in a normal wall outlet vertically. When plugged in, it has an indicator light that glows green, which is a nice touch, but doesn't really mean anything other than that your wall outlet is working.
The charger has two ports. A USB-C port and USB-A port. The USB-C port is a Qualcomm QuickCharge 3.0 capable port. An ability that my Nexus 5X can't take advantage of, but is much appreciated by me nonetheless. I'm sure the charging speed will come in handy in the future. The USB-A port is a "Volt iQ" port. Volt iQ is essentially a small circuit that is able to detect the current required by the device that's being charged. It's a pretty cool feature that expands the compatibility of this charger to almost any device, even Apple products or older devices before standards (like 2.1A charging) were set in the industry.
Performance
I'm gonna be honest here, I had planned on presenting a bunch of data and results from readings taken using the popular app, Ampere. Unfortunately, readings were so sporadic I didn't even bother to continue with recording the information. I'm assuming this has more to do with the phone and its battery temperature / CPU usage and less to do with the actual charger itself. I can tell you that a pattern that quickly emerged is that the phone would not charge any faster than 2540mAh from either port, using any of the supplied cables.
2540mAh is a very respectable number and while the phone is capable of charging at 3000mAh, this number doesn't really bother me because, if anything, the battery will stay healthier longer.
It should also be mentioned that immediately after receiving these cables I visited a good friend of mine for a weekend. He has two young dogs, one German Shepherd that's 6 months old. To my dismay, I came downstairs one morning to find the dog chewing on the cable. I removed the cable from the dog's mouth and to my surprise, there was no damage to the cable. If anything this is a testament to the cable's durability. Teething Puppy-Approved.
Overall
Overall, I'm quite happy with the quality and performance of the charger and the cables. I would recommend these products to anyone looking for a good and up-to-spec charger for a decent price.
Additionally, I'd like to thank Tronsmart for the charger, cables and the opportunity.
Nice review, I just picked one of these up.
Got this today, along with a Tronsmart USB type C cable. Phone identifies as charging rapidly, when its both charging alone as well as when it's alongside an iPhone 6S. Seems like a great charger.

it's a 33w charger, so it can charge both the type c device (15w) and a quick charge device (18w) at max speeds. a non quick charge phone will also top out, albeit at 12w so you're not pushing the charger to its limit
Not pushing it to the limit if fine for me, I couldn't find a better alternative at that price point so far anyway.

So yesterday my girlfriend plugged her phone (Galaxy S6) into this charger via the VoltiQ port while my phone was already connected and charging via the USB-C port. We took a quick 1 hour nap and my phone was fully charged while hers was only at 45% when we woke up. Charging two devices at the same time should not effect the speed of the charge for either device but I figured I'd follow up with this info. Not sure what happened, maybe the phone throttled the charging because the battery got warm.
