That's because the iPad charger doesn't have the data pins shorted out to enable fastcharge . Easiest way to accomplish fastcharge with your charger, is to buy a charging cable (data pins shorted out, so it is not a data cable:
http://dx.com/p/usb-male-to-lengthe...for-samsung-i9500-9300-htc-white-100cm-207353
It even has the lengthened micro usb connector the Nexus 7 needs.
Or maybe better, buy this one, found in another thread here on XDA, this one is confirmed to work in fastcharge mode with any usb charger:

Yes I know, and that's the reason the iPad charger won't work on fastcharge.
You need to either shortout the data pins of the iPad charger, or use a charger cable with shorted data pins ( a so called charge-only micro usb cable) to make the iPad charger use full capacity (fastcharge mode). There are also cable adaptors for sale that will shortout the data pins for you.

Yep, that one works because it follows the USB standard rules, and not the Apple USB standard.
No iDevice (iPhone/iPad) charger will fastcharge an android phone or tablet without modifying the datapins or use a charge-only cable / adaptor.
The Blackberry Playbook charger is known to work

Get an HP touchpad charger if you can. I can provide empirical evidence that it will actually charge your n7 20 minutes faster than the stock charger. I posted a thread about it here some time ago. "Best aftermarket charger ..." Or something like that.
Plus, my HP touchpad charger hasn't failed to work with whatever device I've plugged into it - idevice or android.

I will suggest the HP touchpad charger for use with the N7... they work great and produce no noticeable heat when not connected... shows good efficiency.:good:
Check Ebay -= just did a quick search and got 131 hits anywhere from 8-20 USD. I"ve bought 2... one is firmly set to be my preferred travel charger for any USB device.

+1 Re: HP Touchpad charger
Someone did a in depth look at factory and aftermarket chargers and it came out way better in terms of current provided and cleanliness of power without spikes or dropouts.

That will do the trick - but you don't need another cable if you already have one.

I went with the charger without cable option and got 2 chargers for less than that price. Just have eBay sort the search results by price+shipping and optionally USA sellers only to find a better price without waiting for a slow boat from China.

If the charger puts out less than the tablet needs then it will just charge slower (or not at all if it's really low) and if it puts out more than the maximum the tablet uses the extra will just go unused. Voltage is a different issue.

Having your device plugged into a USB 2 500mA computer port obviously charges slower then a 2000mA wall charger. It would be pretty faulty design if plugging your device into your computer would cause hardware damage.

Man, this really sucks, the Monoprice cable mentioned earlier in this thread is having the same issue I had with another micro USB cable, it doesn't seem to fit into the Nexus 7 snugly, it doesn't seem to go in all the way. (I hope I don't have a busted charging port), It doesn't seem to charge it at all, even with the stock Nexus AC adapter. I'm about to break down and buy the official Google charger again, even if all I need is a new micro USB cable.

I'm using 2 different monoprice cables, one in my car and one at home, and both fit well. Sounds like the port has gotten damaged.
Sent from my Nexus 7 using Xparent Purple Tapatalk 2

So, I just decided to buy a whole new charger off Amazon. If that won't work and I determine that the micro USB port is busted, I'm not going to be very happy, haha. does anyone know if Google repairs them for a fee?

I use a Playstation Vita charger which seems to charge my N7 very fast. On the other hand, I've tried an old mobile charger also and the battery level goes down whilst plugged into it.

If under warranty and purchased from the PlayStore, yes, otherwise, if under warranty, ASUS.

Nexus 7 Car Charger

I was just wondering if anyone here has spotted a Nexus 7 car charger? Does it not matter if it's not specifically made for the Nexus 7? I'm trying to find one to buy online and I'm having some troubles. First post here I think I came to the right place though. :laugh:

Clicked thanks on accident lol. Any USB car charger should work, but I would make sure you grap a 1 amp one just so it has enough output to charge the tablet at a decent rate.
probably better with a 2amp one. samsung makes one for the tab2, about $12 on amazon, and just use your own microusb cable to connect to it.

Yup, go with a 2Amp one. Most of the cigarette lighter usb chargers are 2.1A.
Avoid the cheap Chinese 2+Amp car chargers, they can be so badly made they cause enough interference to wipe out your FM radio.
/edit 1Amp will be fine but don't go lower, the N7 would likely burn it out.
FYI I tried a 5v 1a wall charger and my gnex7 said f u wouldn't take the charge. 2a or nothing I say

Do you already have the Nexus 7? If so, can you take a look at the charger and see if rated at 1A output and/or try to charge it with a charger that came with your phone?
I am just curious if it can actually charge with less than 2A. The charger listed in the Play Store outputs 2Amps and I thought most tablets require 2A to charge.

Still waiting, should only be a couple of days now though...
I know this is something most people never do...but if you read the manual for the Nexus 7 it says you can charge it on a standard USB port with the Nexus 7 in sleep mode (no doubt because the power draw is much less). Standard USB ports are typically .5A...sometimes less. I would say that's the actual minimum. For the fastest charging 2A is what you want though.
The ASUS charger that comes with the N7 is rated at 2A (10W). I tested an old BlackBerry 0.85A (~4W) micoUSB charger and it seemed to work fine and the N7 didn't complain though I didn't do any scientific tests against the charging rates.
The 0.5A (2.5W) chargers probably won't even charge the unit if you're actively using it.
Cheers,
Kermee

Yeah...read my previous post...the manual says you can charge on a standard usb port (0.5A sometimes less) but only if the Nexus 7 is in sleep mode...ie you're not actively using it. If you can't charge it while connected to USB and it's in the sleep state...then your usb port is probably a low power USB port (<0.5A).
For those looking for a good backup battery charger for it...I recommend this one: http://www.amazon.com/gp/product/B005NGKR54/ref=oh_details_o05_s00_i00
works perfectly with my Nexus 7 (just make sure to use the correct USB out port on it as only one of them is 2A)
DealExtreme Charger
Saw this one on DealExtreme, even come with cable:
http://www.dealextreme.com/p/car-ci...-port-for-google-nexus-7-tablet-146751?item=8
Will be ordering will update when arrives. Also they're carrying Nexus 7 Cables in Pink, Green and Orange.
Was using a Sprint micro-USB plus charger (model PVX8823) with attached cable and standard USB port for 2nd device that I was using for my phone. Output is 0.65Amp which isn't sufficient and will slowly drain the N7 battery while in use. ~$35 at Sprint retail store. Wouldn't recommend for obvious reason.
Fortunately, had a spare Motorola SPN5400A 1Amp I bought with some screen protectors from Amazon because it was cheap like ~$5. 1Amp is sufficiently to maintain the charge while in use at near worse case running 3D games like Dead Trigger, Shadowngun, etc. So, 1Amp is minimum threshold.
You need a charger that:
1) Is capable of 2A (1.5A may be sufficient, 1A is a little too low)
2) Shorts D+ and D- together - This rules out most iPad chargers.
If it says it is made for iPod/iPad it will not work without modifications or adapters.
Samsung tablet chargers will work.
If you take an iPad charger, open it up, and short D+ and D- together, it will work.

Most chargers for android phones will work. I use my HTC charger for ,mine and I bought a car charge that has the standard micro USB connector but also has another USB port so I can charge 2 devices at the same time with 1 charging unit. You droid razor charger will work just fine. You just need to locate a charger that is capable of charging 2 devices at the same time such as this one

Check out this oem charger from Sprint. Its a dual port charger with a 2a output and you dont have to worry about buying a knock off charger that may or may not perform as expected. It also can be used as a wall charger. Good price too....

So are any of these confirmed 100% to work? the one a few links back (GTMax) says works with iphone, and I thougth that meant would NOT work with N7. So I am confused on what will work, and I am already on my 2nd Nexus7 being I blew out the USB trying a bunch of differnt chargers for the car.
I would like something that is small and can have multiple USB plugged in, but not a show stopper, just hope to find something on Amazon (Prefer Prime) so I can oder with my case today. Really want to use this in the car more (GPS\GoogleMusic..ect.), but with no power not a great option.
Thanks in Advance,

Charging Nexus 7 - travel charger

Hi all,
Can I please get some advice from someone who might know better than me. I have been using the following charger on my travels to charge an iPad and Samsung galaxy nexus at the same time:
http://www.amazon.co.uk/Skross-Char...?s=electronics&ie=UTF8&qid=1342643375&sr=1-23
I've just plugged my nexus 7 in on its own and I get nothing.
I didn't think the nexus would need a higher amp than the iPad? The Asus plug that's charging the nexus says its 2amp and the travel charger says its 6.5amp. Am I being amazingly blind or stupid here?
And if I need a new travel charger for my trips into Europe can I have some advice on what to buy before I buy something else useless.
Thanks all!

Nexus 7 trouble with other chargers
I see the same issue.
The Nexus 7 charger lists: Output 5.0V===2.0A, Nexus 7 will charge.
iPad 2's charger shows: Output 5.1V===2.1A;Max 10Watt, Nexus 7 will not charge,
Philips universal charger: Output 5V===2A; Max 10Watt, Nexus 7 will not charge.
Blackberry phone charger Output 5V===500mA, Nexus 7 will not charge.
Blackberry phone charger Output 5V===700mA, Nexus 7 will charge.
To answer the OP: The Amazon product page clearly states Output 5.0 VDC / 1000 mA max. N7 needs 2000 mA (2A). Derping in public again. Don't mind me. :silly:
To add to the list:
Samsung Galaxy Tab 2 7.0 Charger: Output 5V ⎓ 2A; Max 10Watt, Nexus 7 will charge.
XtremeMac IPU-IH2-11: Output 5V ⎓ 4.2A (2.1A per port); Max 20Watt, Nexus 7 will not charge. (Galaxy Tab 2 7.0 charges though.)
The N7 seems very picky about chargers, unfortunately. My XtremeMac is now powering my charge cables for my wireless mouse and keyboard, freeing up 2 USB ports, so not all is lost I guess.
I have a 2.1a car charger, but it doesn't charge it.
http://www.amazon.com/gp/product/B007TV88F2/ref=oh_details_o00_s00_i00
EDIT: Interesting. It will not work on the car charger wiht my "charging only cable" which has shorted out datapins to register as an AC source. But, it does charge on a normal USB cable.
I have a tf201 charger (here i refer to the usb block, not the cable) that seems to super charge the nexus 7, that is to say, very fast. The tf201 charger is 18 watts. Also, I have noticed my usb 2.0 ports on my desktop will not charge the n7, but my usb 3.0 ports will.

I started a related thread asking if anyone has examined the proprietary aspects of the charger here:
http://forum.xda-developers.com/showthread.php?t=1780211
Basically, we should be able to build (or eventually buy) some type of adapter to enable proper charging with any 2A charger after we figure out exactly what the charger is doing. I wouldn't be surprised if all Asus tablet chargers already worked properly without an adapter.

This answer is clouding up a lot of legitimate discussions. The current rating doesn't matter to this conversation at all. If the current is above 0 the device should show the charging icon. If not, there is some other problem.

You are correct that my remark about the OP's charger's current was not a valid point. I have stricken it from the record.
That said, some serious weirdness is going on with the N7 regardless. On the XtremeMac charger the N7 will charge. But incredibly slowly, and the battery status reads as discharging, even though the line on the battery graph is rising. I don't even know where to begin in trying to explain that.

Agreed. I bought a pair of dual 2A chargers and neither of them will charge it at all (no charging icon). I tried shorting the data lines and still nothing. The dual charger that came with my Razr will charge it slowly (about 16 hours from 0 to 100%). My old 700ma Blackberry charger works just better than anything other than the OEM charger. Frustrating and I don't want to keep ordering different chargers with my fingers crossed.

I don't know what a XtremeMac charger is, but I'm assuming it's for charging an iphone or ipad or something? the Nexus 7 and the apple products don't share the same charger design, so the Nexus is probably only drawing 500mA while charging from it.
You can also add the MonoPrice 8856 charger to the list that do not work with Nexus 7

I have two chargers that work.
1: Nokia 1.2a fast charger
2: Blackberry 1.8a charger
both have integrated charging cables, which are 6ft in length.
The Asus transformer prime which is a USB charger with proprietary cord also has something weird. Other USB chargers with the same power specs connected with the Asus USB cable won't charge the prime. Or they charge where it literally takes like 24 hours to reach 100 percent.
There's something different in that Asus power plug on both devices it seems.

I'm not sure what It's output is but the standard Verizon branded micro usb charger does a great job charging my N7. I think they for sell around $30 in the VZW stores tho.
The 1.0a charger that came with my LG Revo works great, almost as fast stock. I bought 2 extra of that charger on amazon about 9months ago for under 10 for the pair.
Also the charger for my old Droid (.7a iirc) works as well, but it's slow as hell with the screen off, and barely keeps up with just web surfing.
The Charger with the HTC Desire seems to be charging - though slowly as its a 1A charger.
Does anyone know whether the International Samsung Galaxy S II charger works?
The TF101 charger works great, and fast too - about 1% a minute.
My Samsung SG2 (i777) charger seems to work with the N7

2A Charger Please

I have read countless threads and looked at many chargers and I just can't seem to find a 2a car and a 2a home charger. I just ordered this charger and this cable and it just doesn't work above 700ma. When I use the stock cable I get to 1300mah for a sec and then about 900 steady. This is on both ports. Someone please help me before I lose it! The only one that works at 1500mah is the cable and charger that came with my phone.

Thanks in advance.
Well, I can say from repeated certainty that this 6' cable charges at the same rate as the stock cable but is actually nice.

I'm also looking for 2A replacement... How's the charging time compare to the stock Note 2 charger?
how do you measure the output while the device is charging? Is there an app to test how much juice is coming in real time?
I use a 2A HP Touchpad charger in my living room and a T-Mobile branded 3A dual USB charger in my bedroom (see links below). The T-Mobile charger charges my Note2 from 9% to 100% in less than 2 hours when I only use 1 of the USB ports. I'm not sure what the rate is when both ports are used. I've had this for a couple years and use it to charge (individually and simultaneously) my phones and tablets without any problem.

I've had this for a couple years and use it to charge (individually and simultaneously) my phones and tablets without any problem.

I'm using "Battery Monitor Pro" not sure how accurate it is but most people I ran across seems to use that app.
This is the stock ac charger result

When I use the stock cable I get to 1300mah for a sec and then about 900 steady. This is on both ports. Someone please help me before I lose it! The only one that works at 1500mah is the cable and charger that came with my phone.

Lol, I am on my third phone and third charger and they all acting same just within a week. Nonsense. This device has some charging problems.
I just wanted to say best of luck to you.

I just went to Walgreens also. They have 2 usb port car chargers that charge one port at 2.1amp and the other at 1amp. It was only 10$. They also have a 2.1 amp wall charger as well.

Yep that sounds like the one I have. It has a little pull handle on it too

2 Amps. Extra USB port. Fixed wire (so you don't lose it). Bought it in October and it works awesome.
$12.89. It's the best option out there, IMO (aside from the stock one).

I have that one, super slim profile so it looks like its part of your car instead of something plugged into your cigarette lighter. Works like a charm.

[Q] Charger

Can someone tell me if the Htc One charger is the same as the One S please.
Most chargers nowadays unless an iDevice are the same 5v micro usb

Thanks, just making sure. Replacing chargers and car chargers and HDMI adaptors is almost as expensive as the phone itself. :laugh:

Careful. HTC does something funky with the wiring in their chargers and phones such that, when using a non HTC charger, the phone will only charge at 0.5 amp, vs 1 amp with an HTC charger. Net result is that your phone will take twice as long to charge with a non HTC charger. There are several threads on this subject, and I've observed it first hand on my One. The non HTC charger shouldn't hurt your phone though, only your patience...

I've never had an issue.. have had HTC for years now and have gone thru several chargers bought from walgreens and they all seem to work fine. I usually charge overnight anyway so I never time the charge lengths. Ymmv I guess?

I usually charge overnight as well. But I travel a lot, and when I do the GPS - a battery burner - gets a lot of use. What got me started exploring this, was when I saw my HTC ONE battery going in the wrong direction (slowly) while charging in the car while using the GPS. This led me to learning more than I ever wanted to know about HTC chargers and their funky wiring ... Apparently you can get around this by shorting two wires in the USB cable, but I have no intention of trying that!

I don't think the problem is at HTC but the charger you might have. I have successfully charge @ ~800mA (1000mA = 1 Amp)with different chargers ( Asus charger, Samsung charger and a newer palm charger). My new blackberry charger can charge @ ~600mA.
If I use my older palm charger, my Nokia charger, my old blackberry or a dollar store charger, it will only charge @ ~3xxmA.
If you read the spec carefully, you will see most newer *smartphone* charger max @ 1A, and older charger max @ 500mA. (or my BB charger max @ 800mA. )
So it's OK to use non HTC charger, just be sure to read the spec and find one charger =>1A.
Hope this help.
I'm on the lookout for a car charger someone can confirm will charge the One at full 1A speeds. I don't mean one where it claims to on amazon's site, but that you've actually witnessed it. Thanks for any help!

Yeah, I can't find anything on eBay or Amazon meet their description. The one works good for me is a Verizon Charger but it cost 35 usd...

That is correct, usb specification is 5v, with 500mA (0.5A) maximum, hence the modified cable you refer to. The simplest way if you don't wish to modify cables is to buy HTC car charger

Which will charge at up to 1A with any HTC phone

You can find HTC chargers on amazon that will give you the full 1 amp. Look for older phone models like treo pro or mytouch 4g and they'll be cheaper but work fine.

What happens if I charge the phone with a 2am charger? Does it damage my battery? Will it charge faster?

The charger *should* only provide 2A if the device (phone) request it.
Just thought I would chime in on some observations here. Long story short, when I bought my HTC One, I left the charger in the box and continued to use my multi-port USB charger with 3x1A ports and 1x2.1A port.
When connected to the 1A port, I found it quite strange that my phone was taking 4 hours or longer to fully charge. Also observed the same thing when connected to the 2.1A port. I was thinking that something was up with my phone somehow limiting the maximum charge current.
Anyway, I read a suggestion to use SystemPanel Lite to check for USB or AC power connected and sure enough it was reporting USB power. I remember the case with my Xperia X10 where you have to short out the two middle (data) pins on the cable or in the charger so that the phone detects that it is being connected to an actual charger. I tested it with my old Xperia charger, another generic USB charger, and the HTC charger and managed to get SystemPanel Lite to report it as AC connected.
But here is the interesting part. I have a car charger rated for 1A. Initially it never worked with the Xperia X10 until I opened it up and shorted out the two data pins. It has worked ever since. However, when I connect this to my HTC One, it still reports it as USB connected.
This has got me thinking that there maybe something more than just shorting out the two data pins for the HTC One to detect that an actual charger is connected. Just some food for thought.
Don't tell me HTC pulled an Apple and we have to buy only HTC chargers to get full speed charging? Does anyone have a confirmed non-HTC car charger that reports "AC" charging in SystemPanel Lite?

As per my post, I tested a generic USB 1A charger (it's at home, but it was one that was supplied with a Netcomm MyZone) and with my stock Sony Ericsson USB 700mA charger, both of which reported as AC connected. There has to be another way that these can be detected as chargers other than a simple short of the data pins.
Tested not to work so far has been an iPhone charger, Amacrox AX025-TACH1, Philips Power Bug, and two generic USB car chargers both with the data pins open then shorted.
Non HTC charger plugged into wall reports ac power. Proof

Decent USB cable in the UK?

Hi,
Can anyone recommend a decent USB cable for my sons N7?
Need to get a replacement, but the ones i currently have are not beefy enough to charge properly.
Cheers
Paul

Same problem, can only find pathetic skinny fragile things.
I have used this cable without any probs
AKASA part no AK-CBUB05-10BK
bought from CPC order code CS20881
Try a flat ribbon cable, Amazon Uk have them http://www.amazon.co.uk/s/ref=nb_sb...onics&rh=i:electronics,k:flat micro usb cable Various lengths and colours. I use a standard 1.2mtr blue one that I bought last year.
I'm using Logitech cable for charging (got it with the mouse) and Nokia cable for PC (they are always connected, that's why separate cables), so get one of those.
I've only had problems with 3 years old Samsung cable because it kept falling out (it stays in on my SE phone)
I really doubt beefyness of the cable affects charging though. I charged my tabled on just about any cable I've found laying around in the house with no problems
The reason as to why your charge cannot keep up is most likely due to using a charger with lower amperage (i.e 1amp/1A).
As long as you purchase a 2amp charger and compatible usb cable, then you shouldn't have any more issues with draining the battery faster than it can be charged thanks to the 2amp charge rate.

Thanks for the reply guys, this is using the Asus charger that came with the device, just that the original cable split, so I need a replacement.
Have looked at the cables, might get one of the flat ones as they look good.
Cheers,
Paul.
Just to let you know I bought the flat ones and they fit and work really well.
Thanks for the replys all.

Trick is to get a short a cable as you can. The impedance really effects charging. The difference between my stock and a 6' cable is like a 60% drop.
