A/C adapter

I know the Streak 7 requires about 5.4 volts and something well over the normal 500mA to chage so not just any A/C to USB charger will work. Anyone know offhand of a good source for an adapter that will charge the 7 and preferably has a folding plug or the like so it's streamlined and also something that's rugged. I don't want a cheap $1.99 cent no name piece of plastic.
Thanks

Any 5v 2 AMP charger will work.

I too am looking for an a/c charger and would love an affordable recommendation. Ive looked everywhere and I find chargers that are like $24 (way too much) or like a dollar (don't trust it at that price). Thanks alot.

I have one HTC 5V 1A adapter from my old Hero that works (folding plugs), also LG 5V 700ma works as well (from Optimus One). I am sure these are slower at charging but they do work. Would be good for overnight charging.

Any ideas on a good, AA powered USB charger? I know AAs will get eaten pretty quick, but I have some Eneloops sitting around doing nothing and I'd love to get a little more juice on the go.
Juice on the go. Now I have a picture of a white Bronco slowly fleeing the cops down the freeway stuck in my head.

Thanks. I guess as long as they work it doesn't really matter how long they take to charge. Hopefully with all the tablets coming out, a/c to USB 2 amp chargers will become more accessable at lower prices. Until then ill just use a 1 amp charger.

I got that one, but it only worked for about 20 seconds and then never worked again. I got a replacement, same deal. It seems very cheaply made and heats up very quickly. I made sure my Eneloops had a full charge, too.

I use the newest iphone 4 (white phone) usb plug. The printed spec says 1 amp, but it works fine, I am assuming it is the same unit as the ipad, but a different sticker. iphone 3 plug did not work.

Yeah, i thought it looked shady. But hopefully the cheap 1 amp charger i bought will work. There were some promising rechargeable external batteries on amazon, they run like 60 bucks but they put out an amp and look like they are high quality.

The charger that I bought works great! I'm sure its a little slower charge than the original charger but it is much easier to travel with. Link below replace "DOT" with ". "

naw not same as ipad charger that charger is kinda big about 2X2X1 with foldable plugs and also removable plugs to attatch an extension

fyi....1amp is definitely fine. Their car kit includes a 1amp 12v usb charger. Kinda peeved. I was expecting a 2amp one similar to the ac one that comes with the streak. Thankfully I only paid $7 for the car kit which is pretty much what I'd pay for another dock cable.

Is 1Amp enough to charge with the screen on the brightest setting while using gps and wifi ?
Also, I ordered 3 cables from china for $9 total. Ill let you know if they work properly and if so ill link them. Im planning on a cable mod for usb-otg on one of them. Will report back. Also, anyone have a complete pinout on the dock connector? Trying to find out if the only charging pins are the ones used for usb connection. We are going to need to be able to charge while supplying power via usb to devices. Thanks!

I haven't re-downloaded copilot yet since upgrading to DJSteve's 3.2. So I haven't tested everything out yet. Have my hotspot though so I theoretically can. With more 2amp chargers out there, it should be a moot point though. I just picked up a dual one that has both a 1amp and 2amp. With the loaner car at the moment, I'm kinda just dealing with the usb port for charging. Kinda cool it even has usb.
I will say, the viewpad 7x is catching my eye though. And with HC on the Dell, resell should be easy. Just saying.

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,

Fast charge hack

I bought what i thought were a couple higher quality universal chargers. They charge my razr fast but won't charge my nexus 7 at all. I have one of the chargers pulled apart but before I do any soldering I want to make sure -- if I cross the 2 data points will it work?

Well I couldn't wait 10 minutes so I tried. Answer: no. Wtf?

Can anyone tell me how to hack these chargers to make them work? Is there a resistor I need to remove?

Isn't it more likely to be a software thing?
With my samsung Tab 7.7 i couldn't charge it using my ipad charger until a Dev modded the software on the tablet.

are they 2Amp chargers? most universal chargers are only 1Amp

Well whatever the problem is, I want to charge my tablet in more than one place, I want to charge it faster than the 16 hours generic chargers are taking, and I don't want to pay $30 for OEM chargers.

If your tablet is taking 16 hours to fully charge, return it. I can drain mine after heavy use of the day and its still fully charged in under 6 hours.
Sent from my Nexus 7 using xda app-developers app

@soldeus: There's nothing wrong with my tablet. The OEM charger works fine and some of my generic chargers work, they just don't have the current. (See below)
@vivan: They are 1A chargers, but they should still work. They don't charge at all. The 500ma Blackberry charger I'm using here at work will charge it in about 8 hours.
Ironically the move to almost-universal micro usb chargers has made the market for them even worse. Now, instead of having to buy a new charger every time you buy a new phone, you have to buy a dozen different chargers till you find one that actually works. Like I said, I didn't try to cheap out. I got a high quality charger.

The OEM charger is 2A for a reason. Because the tablet uses more power, it needs more current to charge at a fast pace.
Your generic 1A chargers are probably just enough to keep the tablet powered on, without draining (or charging) the battery.
If you can find a 2A universal charger, it should work just like the OEM one.

No, my 1A chargers are doing NOTHING at all. I plug it in and the charging icon doesn't come on. Reviews have tested these chargers at about 950ma and as I said, my 500ma Blackberry charger isn't too bad.. It's not lack of power, it's something else.
My guess is it has whatever resistor it needs to make it an "ipad" charger. And the vast majority of 2A chargers will, too.
So.. back to my original question: what do I need to do to make this charger charge my tablet? I KNOW it's possible. I just need to find the guy who can tell me how.

I also need a charger for my car, my usb power adapter in the car does not work, need to know what car charger will work as this tablet is supposed to be my car stereo replacement, sucks having to bring your stereo in to charge it and hope it lasts till you get done work

I bought the Scosche dual 10 Watt car charger, isn't here yet though. It does say it wont charge the Samsung tablets, maybe due to the proprietary cord because apparently there is a cord that works with them. It's not a specific ipad charger and does say it works with Android devices and tablets.
On a side note, what's the best way to determine what your N7 is actually charging at?

Both of my generic chargers won't work either, a 2.1A generic iPad charger, and a 1A standard USB charger. Considering it WILL charge off a 500ma USB port, it's not a current/amperage issue, it's a software/proprietary hardware issue.

For $30 you could order a handful of different ones on ebay or monoprice and find something that works. But I want a dual charger.

I won't say 100% but I would bet the probability is very high. For the 1A charging they all seemed to play the same game with the voltage on the data lines. Not sure you'll get 2A but you'll at least get 1A.

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.

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.

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.

Will using chargers not putting out the proper amperage cause any hard ware issues? Just curious.

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.

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.

Car chargers

Just thought I'd share something simple that helps if ur charging ur phone in the car. I've noticed a lot of chargers charge at 1 amp. Seems like it took for ever to charge my phone in the car. I recently bought a 2.1 amp charger for $10 and the charging difference is huge. 6-7 % in 10 minutes with full brightness and gps on. Just thought I'd pass this info on. Sometimes it's the simple things we overlook..

There is a lot more to it than just that. Many actual 2 amp + battery chargers refuse to charge at the full 1.9 amp. Apparently the stock samsung charger gives off a certain resistance between the data terminals. Some cheap usb cables drop the resistance to where it will not charge at full 1.9 even with the correct adapter.
I ended up soldering some resistors in my car charger and replacing the 2 wire usb cable with a 4 wire usb cable that I had laying around. It now charges at the full 1.9 amps. It's rated for 2 amps.
Found all the info here. http://forum.xda-developers.com/showthread.php?t=2274321

i like this one

thanks for pointing out the amps primo.. went and got 2 amp charger from biglots for 8$..much better.. was using a very old one and it was worthless.. also using factory cable instead of aftermarket made huge difference

I charge using external batteries...most of the time. I take it that using the correct cable would make a large difference as well

I use Monoprice PID 10239, works great
edit: scratch that, monoprice PID 10239 has a 3 amp fuse which blew when my gf tried to charge her iPhone at the same time as my GS4.
search TopG charger on Amazon for a more compact, fuseless 4.4A car charger. It's $9 and Prime eligible. Fuses in car chargers are pointless since the cigarette lighter receptacle is already fused to 10 or 15 amps in your car.

I bought a car charger from a Chinese eBay vendor and my phone charges from <5% to 50% in roughly 30 minutes.

I actually built my own charger that I hard wired into my car and I love it. I had a snap fish desk charger that crapped out on me, so I bought a lm2596 adjustable power supply for a couple bucks on eBay. Wired that up to the snap fish cable, adjusted the voltage and away I went. The module has a 3 amp capacity so it charges my phone or tablet quickly.

i'm using one of these but the charging keeps cutting in and out. i think i may have fudged up the wiring, i wired it to an add-a-fuse but i may need to just wire it directly.

I would keep the fuse in there. You never know when these cheap electronics will crap out and could potentially start a fire. I would make sure your connections are secure. To me it sounds like loose worrying or a bad unit. I used one of those in girlfriends car, works great-I put a switch in there to cut power if not being used.

I have 4 of these. I love them. I use them with oem Samsung cables and get full charging power on 2 devices.
