Tested a few chargers

The Galaxy Note 2 comes with a 2 Amp AC adapter/charger so I was curious to compare the charging capability of the stock charger to other chargers that I already own. I cut open a USB to uUSB cord and used a current meter to see how much 5V current was flowing from the charger into the phone. These results are only good for a Galaxy Note 2. Other phones will draw a different about of current (probably lower). Details of the setup can be found far below.
The conditions were:
Battery level = 48%
Voltage was measured on the cable about four inches from the phone
Only the charger was changed between tests (used the exact same cable/setup for each test).

The results explain why the Note 2 charges so fast compared to the original Note that I had. Something to keep in mind with dual port chargers...... when I had the two dual port car chargers apart modifying them (the D+ and D- setup so my Note 1 would recognize it as a dedicated charger), I noticed that both chargers used a single 5V regulator and simply ran the power for the two USB ports in parallel. That means that although they say it is a dual 1A charger it could be used as a single 2A charger. I can't say every dual charger is setup that way, but it seems unlikely they would spend the $$ on two different regulator circuits.
Details:
The cable is about three feet long. I cut the cable about four inches from the uUSB connector (where the phone connects). I soldered the ground, data +, and data - wires back together and just left the 5V red wire open so I could insert a current meter (used a Fluke 189 on the 10A mode).
For most people, it is probably best to just buy a car charger that will support 2A for Android. Note that many chargers are setup (their D+ and D- pins) for Apple so you may not get full charging current. That may take a little digging around to see what others have found.

Very interesting! Thanks for posting this as I'd prob would have bought an Iphone car charger. I now know not to, question is what one would be best for matching amperage draw compared to the stock Samsung one(might just order the official, it's cheap).

Thank goodness I bought a lot of those HP touchpad chargers!

I find it interesting your numbers are so far off this breakdown:

One of you isn't right...

I would love to buy a 2A OEM charger but Samsung hasn't had it on their site for quite some time.

I cleaned up on those HP Touchpad chargers when they were blowing them out for $5 each. I bought five of them and scattered them all around home and work. Of course the GN2 has such good battery life that I probably won't be needing them much.

He tested the maximum current you could get out of each charger. In other words, how much current can you pull until the current limit of the regulator kicks in and the voltage severely drops. I measured how much current the Galaxy Note 2 will pull from each charger. The phone dictates the amount of current pulled as long as that current level is below the maximum current of the charger (he lists the maximum possible current for each charger). If I hooked up the stock Samsung 2A charger to a GS2, it would likely draw less than 1A because it has a smaller battery so it is designed to charge at a lower current. All my results are specific to the Galaxy Note 2.

Here's another crazy data point. I tried 3 different chargers and 4 different USB cables with a killawatt. The stock white cable pulled at least 1.5 more watts than the other cables, which were note1, evo3d and monoprice cables.
At this point I think Samsung increased the wire gauge on the note2 USB cable, to get the resistance down a bit. Hmm this might even be measurable. More stuff to check out tomorrow.
Oh, I tested several 2amp or greater power supplies, and the stock note2 PSU always did slightly better.

USB-C Charger replacement options?

I bought a Nexus 5x from the USA, but I live in the UK. I will therefore need to replace the wall charger when it arrives.
For my old Nexus 5 I use an iPad charger. This is fast, and adaptable, since I travel a lot, I can switch the figure of 8 input on the iPad charger to whatever country I am in, and it allows me to carry only one charger and switch between Nexus and iPad charging.
I realise that the old iPad charger will be quite slow to charge my new nexus 5x. I would like a replacement that is at least as dependable as my iPad charger, but with the usb-c standard. The perfect charger would have swappable plugs, like the iPad, with a usb-c AND standard usb 2/3 ports.
Any ideas?

Nobody found an alternative to this yet? Is it at least possible to buy a standard, genuine, nexus 5x charger with a uk plug?

Can't you just use an outlet adapter?

I now have my US plug and a clumsy US->UK adapter. Not the perfect solution:

I assume that a host of USB-C plugs will come out in the next few months. I am still craving that Apple charger functionality.

I ordered Googles charger, its compact and has a long/slim cable. Recommended!
I have the eu-plug but it should be available in UK model...

I only bought and adapter
Well, I had a Moto X 2014 with quick charger and I lost it, so my replacement was the 5X. In order to keep my previous chargers I bought a micro usb -> Usb C adapter. It's works pretty well for both charging and data transfer and isn't that expensive and you can still use your previous charger.
http://www.amazon.es/gp/product/B018AM74KI?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00
Remember that the OEM charger has an output of 3.0A so you might use a big charger, like the one of an IPAD or S6.

From what I understand though, the old USB formats are not capable of delivering 3.0A. It has to be USB-C. Adapters will turn your charge to 2.5A maximum.
I might be wrong, but have read a few things that suggest this. With my official Google charger I can charge my Nexus 5x fully in about 30 minutes.

I believe you are right, it might not charge at 3.0 A, but it did a good job with my 2.4A Aukey charger. I didn't measure the charging time, but it's aceptable. I can run some tests if your are still interest.

No. This will only charge at old USB ampage (and therefore speed).

I'm curious if anyone has tried these likely fake 5V/3A chargers from ebay?

I'm in the same/similar boat as I've got a nexus 5x with the wrong country's charger-type - With the little adapter-things that just change the plug on the older micro-USB cables, is there a danger of cheap ones such as this http://www.ebay.com/itm/Portable-Mi...333069?hash=item2ca48e09cd:g:LDgAAOSwFGNWSUtf damaging the charger into which it is plugged, or worse yet the actual phone? What would be the cheapest *safe* cable which would charge the nexus 5x off any standard USB A port (ie. older chargers or a computer) (even at slower speed) as I have a lot of older chargers around and like to keep them at a few places so getting one cable is the best way to do this.

I already own an Anker multi port charger, and have just bought the new one which has 1 USB C port and 4 standard USB ports with a total out put of 40W. The USB C port is rated at 3A and charges my 5x quickly. The other ports are 2.4A maximum and I have had no problems charging several devices simultaneously, Its a little smaller than a cigarette packet and has the figure 8 socket for change of power lead when travelling.

I recently received a TronSmart UC5PC QuickCharge 2.0 Rapid Desktop Charger and I must admit that this is a solidly built desktop USB charger. I personally use it on my nightstand where I have an iPad, two cell phones, and two e-cigs charging at night. It uses VoltIQ technology which "identifies the power level required for each connected device." While I am no electrical engineer, I put it through its paces over the course of a week and I haven't had any issues charging various electronics. It handled various USB devices I had with various power requirements without any issue. Nothing got hot, nothing blew up, and nothing caught fire. YAY!
The QuickCharge 2.0 port works great with the Samsung S7 Edge putting out 54w and the phone does indeed recognize that is is on a fast charger. It brought my phone from 1% to 100% charge in about an hour and a half which is in line with Quick Charge 2.0 average charge times.
Based on their site, they do have a Qualcomm certification for QuickCharge 2.0 for this desktop charger:
It is It was perfect for me as I didn't need a huge surge protector with a ton of adapters anymore to power and charge my gadgets so major bonus points on giving me back some nightstand real estate.
I like the fact that it is heavy and feels very sturdy. Definitely beats a lot of other desktop chargers that are very light and slides around all over the place. I do wish they added little rubber feet on the bottom so it wouldn't slide ever.
The ports are labeled but on the bottom/back of the device as shown here:
It's not an issue as the QuickCharge 2.0 port is BLUE.
I've tried many desktop chargers and this one is my favorite. I am going to nitpick a little and say I wish there were two QuickCharge 2.0 ports but it is still a great space saving efficient little box!
Build Quality: 9/10 - Could use rubber feet.
Charging: 10/10 - It's really what it was made for and it definitely does it's job.
Design: 9/10 - Its a black box. Nothing fancy. No LEDs but I wouldn't want a LED anyway.
Overall: 9.3/10​

All in One USB Type C Hub

Hello guys,
I recently bought a Galaxy Tab S6 so I am wondering if there's any good all in one hub for this pretty device. I need to connect HDMI, keyboard, mouse aswell wireless controller and my headphones. Also if it's possible to charge the tab aswell. Thanks!

I've been eyeing this one, but haven't purchased it yet. Will probably do so next payday.

I had my eye on that, but it lists itself as being incompatible with Original Samsun adapters. I want a hub that'll let me properly charge the tablet whilst it's connected to a monitor, otherwise as soon as you plug it in, you're on borrowed time which stops it being nearly as useful.

Yeah, the hub needs at least 12w of power, plus the 15w you'll need for fast charging the tablet, so it'd need a stronger charging adapter than the original Samsung provided one. I'm looking at Anker's 30w or 60w charging adapter to go along with it. Thinking 60w so the adapter and the hub can pull double duty for my laptop as well. That way I'm only carrying one charging method with me when I travel.

Good Idea, i've tried a 30W (Huawei) charger and although it shows that it's charging, the charge drops steadily so that clearly doesn't work. Probably just cough up for both the PD charger and the adapter so I can be relatively confident that it'll keep it charged :good:
Maybe that way I'll be able to get the wired Xbox controller to work as well., might be there wasn't enough available power to run it...

I bought this much cheaper (I know it's not Anker) Type C hub from eBay: https://www.ebay.com/itm/6-in-1-Typ...?pageci=04b0c239-e4f0-425c-ab87-419beb5be354&
It works perfectly fine, the only thing I noticed is that there is no fast charging available through it (at least with genuine Samsung charger), but it still supplies enough power so that it's not only holding level but slowly charging.

I repurposed my Hyperdrive when I changed from an iPad Pro to the Tab S6. There's a couple of small screws holding the plastic lip on it, but once I took those off, it fit great. Not completely flush with the tablet, but supports everything perfectly. Not the cheapest dock, but I already had it.
https://www.hypershop.com/products/hyperdrive-6-in-1-hub-for-ipad-pro-2018?variant=19332717412414

I bought this hub and love it as it is as slim as the Tab S6. It supports upwards to 60w fast charging with any pd charger and across my Huawei mate 20 pro, Nintendo switch and laptop.

Tried here with HDMI to TV and Logitech radio keyboard with that small dongle. Works like a charm.

Best Charging adapter and cable ?

So when I bought the phone I didn't get the Original charger that come in the box.
I have been using a Ugreen 20W PD+ Ugreen PD cable.
But the charging patterns are very weird. Sometimes it changes at 4000mA, sometimes 2500, sometimes 1500, even 500mA.
Can anyone explain and suggest the most suitable charger with fast charging?

I highly recommend the Belkin 27 watt USB C charger. What makes it A Cut Above the Rest is that it not only has Qualcomm 4+ fast charge but also PD 3.0. This means that it supports Wireless fast charge accessories unlike most USC-C fast charge adapters which only have PD 3.0. It's only $11 w/ free shipping right now on ebay. And it's Belkin so it's made well.

Another accessory I recommend to everyone, is a magnetic detachable USB C cable, These are upgraded design that have a very strong magnet that does not accidentally detach easily. It supports PD 3.0 & QC4+ fast charge & data transfer. Using this cable will significantly reduce any wear on your usb c port. It swivels 360° so at any angle you can use the cord and it won't put strain on your phone.
I use it so that it is plugged in to my one port USB C wall plug and I can switch out and plug in any device (usbc , micro USB, iPhone). When my phone is done charging I'll plug in my 18650 battery charger or I'll recharge a flashlight or I'll even plug in my tablet all using the same cord. Very very cool. It comes in 1M & 2M length. It only comes with 1 magnetic attachment( your choice), so you have to buy more if you want to use more than one device, but it's worth it.
