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....
http://www.ebay.com/itm/130712043019?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_1459wt_1399
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,
Drops

If you have one of the roms that is in development yes. If you have the stock I have found it does a slow trickle but really not worth it. I would suggest using the original charger as it is fastest way to charge.
Now here is a cowboy.....
Any advice on a reliable, robust ROM that does have this functionality?
I used to have it on HC using motley's kernel and script (see development thread). Since moving to stock ICS I'm heartily fed up with waiting three weeks for a 1% battery charge! Joking (but only just)
I am currently using Official CyanogenMod 9 which seems to do well. I also bought a charger at best buy that supplies the required 2amp and my tab charges in around 6 hours to a full charge.
http://forum.xda-developers.com/showthread.php?t=1435868
I couldn't work my way through all 100 pages of comments on the CyanogenMod ROM but there is a pretty strong hint that it has problems with screen behaviour and Google Maps crashing - not really what I would call robust and reliable? Any other suggestions?
PS on the charger - there was plenty of stuff in various old threads that made it clear that having a charger with a 2 amp output is not the whole story. I have one at home from Maplin (I'm in the UK) and it still only trickle charges the tab (little red cross in the battery icon). With the Motley/Pershoot kernel on HC I was able to get a reasonable charging rate from the powered USB hub that sits on my desk.
Yes at first it was but they update it alot and I have had it now for a couple weeks and have had no problems with it. Other then that I would suggest lurking the development forums and tray a couple of them to find what suits you best

*nods* Samsung chargers have a resistor network in them to allow the tab/phone to detect them. There are in fact little USB dongles out there that provide that network so you can plug the unit into non-networked chargers (and even high-amp USB ports) to get (near) regular charging rates from them.
I use the P7300 stock rom with the A1 kernel on top. I have a docking station at work which is connected trouch USB.
It does charge the tab, but I'd rather not refer to this action as charging as it only marginally changes the battery state. better call it "It keeps the tab from discharging".

Has anyone found a wall charger that they're happy with? I have an Amazon basics 2.1 Amp one that charges OK and shows up as an A/C charger in the battery stats, but it's not as fast as the stock one (which already is slow).

If you don't really care about super fast charging time almost all usb wall chargers are the same because of the limitations of a usb cable. Just color, shape, and size might vary
I'm using the my hp Touchpad charger. It seems like it charges faster than the original charger. I'll have to test and see though.

I bought a pogo charger so it won't take up the micro usb slot and also safer charging with pets (or kids). If I'm lucky it will charge faster too.
the pogo charger uses the original samsung ac adapter though.. it doesn't come with one
I just use any random charger I have (I think I use an old Kindle one right now) and leave it charge while I sleep. I have no complaints and have a POGO on order.
I ordered the Powergen chargers for both the wall and my car. They supply 3.1 amps so whatever the max is that the N10 will take, it will get it.
Search for "powergen 3.1" on Amazon and you'll find both.

Thanks everyone for your input. I ended up ordering the Powergen 3.1 charger suggested above. I'll report back on what my experience is. I did note that one of the reviews of that item at Amazon says it charges the Nexus 10 well, so my hopes are high.
Next question - anyone know what happens if you plug in the POGO charger and a USB charger at the same time?
Your charger isnt going to make a great deal of difference in charge time. An updated and/or custom kernel will help a LOT more with that.
The AC wall unit isn't a charger, it's the power supply for the charger inside the N10.
Me and another N10 owner measured how much current the N10 draws from the PS and it was less than 1A, so the device isn't even asking anywhere near the max that the PS can supply. Unless there is someother reason and there very well could be, a larger PS "might" be a waste of time/money.
I think the N10 charger uses a special usb protocol which allows it to charger faster than most

I'm intrigued; how is that? More importantly, does such a kernel currently exist? I started this thread in search of a second charger that just worked as well as the original one. I'd be happier if could find something that did better than the OEM.

What I can tell you is that both powergen units charge the N10 fine.
What I can't tell you is whether they charge the N10 any faster than the stock wall unit. I haven't done any testing.
I'm expecting my pogo cable any day, maybe I'll do some testing then.
There are so many differing theories here, who knows?

Yes so many, maybe if someone would write to Mr google and ask him he would explains it to us hehehe
I have seen some dual USB port PS that are rated "total" for both "not" each port. How is this PowerGen 3.1?
Just check and it's listed as "shared", so that's 3.1A total.
The description clearly states that each port can supply up to 3.1A. If both are used at once, the 3.1A is shared.
I was one of those that ordered the magnetic pogo charger when it first came on sale and I am still waiting to see if I will get my cable.
So for those who are looking for something that could boost charging time I came across this while following the CES convention bloggers. It looks semi promising. It claims it boosts the amp of any USB port as well as wall charger by using this tiny adapter. Here's the official post about it take a look at it let me know what you guys think.
http://m.cnet.com/news/chargedr-lets-you-charge-your-tablet-from-a-laptop-usb-port/57563162?ds=1
From my understanding its our tablet that is preventing more draw from the usb cable not the output of the wall charger.
Sent from my Nexus 10 using xda app-developers app
I'm thinking they purposely slow the recharge to preserve the life of the battery, as this tablet is really designed as a template for the next gen tablets. I'm assuming that this tablet will be in the hands of many devs and constantly being charged and recharged more so than an average consumer device.
Sent from my Nexus 10 using xda app-developers app
That product looks interesting, but I wonder how safe it is. If it's making the USB port from the source actually draw more power, couldn't that cause issues and even trip some voltage-protection stuff on certain motherboards on computers?
It might trip the USB controllers when it draws too much (in modern computers this wont be permanent damage). This is stupid though, there's a reason the tablet manufacturers limit the current draw when it's connected to a computer's USB port.

The only way to accurately read the input rate into the wireless charger is with a USB multimeter. The S7/S7E will lost about 30-50% of the input current the moment you turn the display on regardless of the charging method. In this case the input should be ~9V/2A or 12V/1.5A (both 18W) in theory. If the charger was pulling via 5V instead there would be a lot more heat, and it might cause some issues if the cable has a higher resistance.

So, does S7E benefit from Quickcharge 3.0? I know smartphone and tablet manufacturers need to implement the specific circuitry required to make full use of the fastest charging speeds available.

It's still quite fast regardless of it being an 'old' standard. Maybe there will be a wya to enable it via root unless there's a hardware controller that is holding it back.
Yes, but what i've gathered 3.0 is more of efficiency over speed. Hopefully, an update would do the trick. Not unless, like you said, it's about a hardware thing...

It is if there's support for that standard. It allows you to ste up/down voltage more granularly so that's why
So I tried the original cable that came with the phone and still the battery drops, even with the screen on and GPS off. I may just have a defective unit. I did browse through some of the reviews on Amazon and it seems there was mixed results with the S7, some people were also having issues with fast charge not working.
According to the first note on the item:
Note: For normal charging use any car USB but for faster charging you will need QC 2.0 Car USB like this one - http://www.amazon.com/dp/B01A54EAHE. You can get 10% off by buying both together and using code MNBXDSUK at checkout.
The only reason why the American version of this handset does not support 3.0 is because the Exynos international equivalent does not support 3.0 so rather than create two sets of charges Samsung decided to make 2.0 the standard and not make the international handset owners feel jealous or a certain kind of way. Remember it's a feature offered by Qualcomm and not Exynos chips.

After messing around with the placement of the phone on the charger it seems to now be working. I was able to run waze, bluetooth and stream audio and the battery climbed and held at 100%. Also I noticed the phone did not get as hot. You have to get the phone in just the right place with this charger it seems. I have an older regular wireless charger on my night stand and do no have any issues.
