Anyone found a charger that can charge the N7 over a 2 amp port?
[Nexus 7 Accessories] currydude:
Yoobao 11200mah works with the small micro USB cable provided with the battery back. I'm still awaiting for my anker astro3 to arrive but all battery packs with true 2a ports can charge the nexus 7 (provided you have the right cable)
[Nexus 7 Accessories] dustinpn:
Another Newtrent 9900 post. It works, as the others have pointed out, with just the included USB cables and no others. I don't know if this is just unique to the N7, but to activate charging mode you have to hold the power down for a few seconds, other wise you just get a read out of how charged up it is. I guess maybe its made to work this way, but no instructions were included with mine so it confused me for a minute.

Anker 8000mAh works at 2A with the Anker cable, no go with a straight usb.

I have a Proporta Usb Turbo Charger 5000 that works but only with the supplied proporta cable, there are probably better options if you are looking to buy as its quite old (1.5 years or so)
[Nexus 7 Accessories] robdroyd:
This one works for charging when the tablet is powered off (most likely not enough current to charge the tablet when it's powered up).

I originally bought it for my Sansa Fuze MP3 player,but figured I'd give it a go with the N7 too- I charged it with the N7's OEM AC wall charger- then used the N7's cable to connect it to the N7, so it's pretty convenient... for $30 it's not bad for offline charging:

I have an iGo Green Backup Battery and Wall Charger that I'd previously bought as a secondary charger for our phones.

I can't post links to it (not enough posts), but it's on Amazon, model # is 6630079-1400. I bought mine as an impulse by inside an Office Depot.

The battery capacity is really lackluster ( only 1800 mAh, just over enough to fully charge my Vibrant), but it turns out it charges the Nexus 7 just fine, even while it's in use/screen is on. The catch is that its output is just low enough where the battery will still drain, but very slowly -- and its not nearly the capacity I'd like.

Used the stock Samsung Vibrant USB cord. Can't test with the one the charger came with, as its now damaged to the point of just falling out of the socket. Probably works with the stock Nexus 7 USB cord as well.
[Nexus 7 Accessories] Entropy512:
90% chance that the one cable which works is a special "charging only" cable.

If the charger shorts D+ and D- internally, it will work with a standard MicroUSB cable (including the stock one).

If the charger does NOT short D+ and D- internally (all iPad chargers are in this category because Apple does not follow the USB battery charging standard), then you will require a special cable or charging adapter that shorts D+ and D- together.
[Nexus 7 Accessories] dewiniaid:
This would seem to fit most of the evidence, but doesn't answer why my Samsung Vibrant cable (which does data, as well) works off of my charger. Granted, I might have one of the outliers that really does handle power intelligently, like understanding the portion of the USB spec that allows devices to negotiate for higher power.

Mine also charges fine from my PC, but then again, my PC has a few special USB ports which, among other characteristics, charge devices even when the PC itself is off.

Is the problem then the combination of "dumb" chargers that don't support power negotiation + cables that don't short D+/D- so the Nexus thinks it can actually talk to the other end to negotiate for more power (and then fails horribly)?

Disclaimer: I know just enough about the USB protocol spec to sound like I know what I'm talking about while probably being completely wrong.
[Nexus 7 Accessories] iElvis:
I'm pretty sure this is the case with all the NewTrent batteries. My 99D will only charge using the Galaxy Tab adapter.

[Nexus 7 Accessories] Entropy512:
As I said in the post, if the charger itself shorts D+ and D- (Stock charger will do this, Galaxy Tab chargers do, quite a few others too - just NOT iDevice chargers), then standard cables will work fine.

All that matters is that the device sees D+ and D- shorted to each other. If the cable does it, the cable will work with any charger but not work for data. If the charger does it, any standard cable will work (as long as it's not one with too short of a MicroUSB plug due to interference with the N7's case.)

As to charging from PC - As far as I can tell, the Nexus 7 does support charging at high rate from CDPs. I haven't tested this, but the kernel source indicates that it does.

CDP = Charging Downstream Port - a PC port that supports high-current charging - fairly rare and not many devices recognize them

DCP = Dedicated Charging Port - aka "dumb charger" - a charger that shorts D+ and D- together

SDP = Standard Downstream Port - PC port that only provides 500 mA

If the N7 detects an "other" port (none of the above), it will simply not do anything.
[Nexus 7 Accessories] PoXFreak:
If the cable is dual use (charging/PC connection), then shorting D+/D- is done in the charger. If the cable is charge only, most manufacturers will make the short at the micro USB plug to save a penny or two since they don't have to run 5 wires in a cable, it can be done with simple 2 conductor 22 gauge zip wire.

I had covered this once before In another thread pertaining to MHL, but essentially the USB controller has to see a certain resistance on D+ and D- for the charge cycle to start. As long as the resistance is less than 10 ohms, a charge cycle should start.

Had to back you up an little Entropy... I've done my homework after looking over MHL and USB HOST.
[Nexus 7 Accessories] dewiniaid:
My bad there, I misread the post as referring to the cable, not the charger.

It makes perfect sense now, and explains why so many devices require the "charger only" cables (too lazy to short D+/D- on the device end, presumably.) I guess I lucked out and got one of the few that short on the charger itself and thus works with any USB cable.

This works for me with the supplied retractable cord and USB/micro USB adapter.

If anybody is still looking for a portable charger I just tested my Fuel Tank Duo and it charges my Nexus 7 just fine. The Duo actually can charge two devices at once and I connected both my N7 and my HTC MyTouch 4G and they both were charging properly. I didn't run them to full charge, though. If anybody wants me to test them with full charge let me know. The pic just shows the N7 because I don't have another phone or camera to take a picture of both.

The Duo is available on Amazon: http://www.amazon.com/Callpod-Fuelt...&qid=1344733525&sr=8-1&keywords=fuel+tank+duo

Anker Slim talk charges with the integrated micro-usb . It is low capacity ( 3200), but small size ( this thing is smaller and lighter than my galaxy s2) and integrated micro usb makes it super portable.
[Nexus 7 Accessories] TheDoctor1971:
Just tested my Tylt Powerplant and it charges just fine. It has a full size USB port and an integrated Micro-USB charging cable. 5200mAh so it should give one full charge to a Nexus 7 before needing recharging itself. Plus it fits in my pocket nicely. Tylt has some other chargers they're coming out with but nothing available yet. Their customer service was great when I broke mine. They sent me a new one next day air without question and emailed a return label for the old one.

http://www.tylt.com/powerplant/index.html.

I think the only place you can actually buy it is from a Sprint store but you don't actually have to have a Sprint device to use it obviously.
[Nexus 7 Accessories] MZero:
it is available on Amazon,

looks like a better a choice than the anker since it can completely charge the nexus 7.

Tylt Powerplant working at high amp charge

Picked up the Tylt Powerplant from Amazon based on this thread. Very happy with it in initial testing. Charges immediately using the included cable (both the removable cable and the built in cable) and seems to charge at relatively high amperage. The shot attached was taken at ~73% charge.

PowerGen Mobile Juice Pack 8400mAh

After reading all these reviews I decided to try this pack: PowerGen Mobile Juice Pack 8400mAh

It works good for my Nexus 7 and Galaxy Nexus as well as my wife's iPhone and iPad2

The pack comes supplied with 2 cables and a bunch of connector heads. It has one 0.6mAh port and one 2.0mAh port

I am pretty happy with the purchase.
[Nexus 7 Accessories] bobs2012:
Modified USB-A cable enables charging

Finding that some chargers work with my N7 and some don't (including an expensive battery pack), I made an adapter cable from a short USB-A extension. I carefully cut open 2 inches of the outer cover carefully, separated the braided shield, peeled off the silver foil and found the 4 USB wires. Leaving the Red and Black power wires and braided shield intact, I cut he White and Green D+ and D- wires. On the male USB side I left the cut White and Green wires unconnected and covered them with a small piece of tape. On the female USB side I soldered a 15k resistor between the White and Green wires. ( As stated above, they probably should be shorted together without a resistor.)

Now, all my USB chargers including the power pack work with my N7.

Wish list: 1. find a car charger that works (here I need a mini to micro adapter)

2. an N7 app that turns off charging at a prescribed amount. Then I can set it to say 95% and leave a charger connected without over charging.
[Nexus 7 Accessories] mariolouis:
From what I have read, we cannot overcharge the batteries. There is a protection circuit even when offline charging (turned off). So you may opt out item #2. :)
[Nexus 7 Accessories] Entropy512:
I'm semi-surprised 15k worked - I think the standard requires it to be less than 2k but I'm not sure.

Correct. The SMB347 has built-in overcharge protection.

It can be slightly beneficial for the battery to reduce the maximum charge voltage, this requires a modified kernel. e.g. you can't permanently damage your battery by leaving the device connected to a charger, but you'll get a few more charge cycles out of it if you halt it at 95%.
[Nexus 7 Accessories] morbidpete:
I have a Zagg Sparq 2.0 I can use to charge my N7, I have to use the "General" port as it wont charge on the optimized port, I never leave home without it. It charges it's self and other devices while plugged into the wall, I use it nightly. I have yet to find a USB device it will not charge
[Nexus 7 Accessories] Troute:
The Anker Astro 3 works well using the (S)amsung port on a standard usb cable, it does not work using the i port. Mine charged the N7 from 60% to 100% with about 25% of the Ankers capacity last night.
[Nexus 7 Accessories] eyesparky:
I have found that the New Trent IMP 120D charges the Nexus 7 using either of the supplied cables. The USB to micro USB cable works plugged directly into the 2A USB port, all other micro USB cables I have from other chargers (from Nexus 7, Samsung S3 and HTC Desire) all work plugged into the 'Samsung Galaxy Tab Charging cable' (USB male to female) to the 2A port.

Sadly the same trick doesn't work for my Transformer Prime as it wants 15V 1.2A rather than 5V 2.1A. Frustrating as there is enough power to charge it if only the Prime would accept it. It does trickle charge but doesn't seem to pull down the available current.

Anyway, Nexus 7 works if you don't lose the supplied cables. ;)

Search Monoprice for a 5000mAh USB charger, as I haven't posted enough to be able to include URLs.

This Monoprice 5000mAh unit was able to charge both my Nexus 7 and Galaxy Nexus/iPod Touch at the same time from full size USB ports. It recharges via microUSB port (8-10 hours to fully recharge), but I haven't tested charging the battery and devices at the same time. However, the Nexus 7 only charges from the 1.0A port (battery increased about 2% every 5 min), while the Galaxy Nexus and iPod Touch could charge from either port. They also have 3000mAh with 2 USB ports and a 9000 mAh with one USB port, it's about the size of an iPhone 4 (a bit shorter and thicker).

I have the XPAL 18,000 (the BIG one) and can report the following:

Using a real USB cable, it will not charge the Nexus 7

Using the included XPAL 2-wire charging-only cable, it WILL charge the Nexus 7 at 1A.

This charger also has a 12-Volt power supply, which means you could basically plug a car-charger into it, allowing you to charge 5v at 2A

The XPAL 8000 also has a 12V output, and the cigarette lighter charger work-around would also be effective at charging 2A

Sort of like this:
[Nexus 7 Accessories] FrayAdjacent:
I just recently got 1 of the Anker 2600mAh tube style battery units, and can verify that it will charge the Nexus 7 albeit slowly. I got it more to be a power source for Galaxy Nexus while I'm out round because that thing sucks power and can't get through a day very well.

I'm using a PowerGen Mobile 5200mah battery pack. Uses standard USB cables and with a generic charging/data cable it shows AC-charging on my Nexus 7. It has enough power to fully recharge my Nexus. Also seems to charge (slowly) if it's plugged in and I'm actively using my tablet.

Very inexpensive for the battery size, only $30 on Amazon.

EasyACC 12000 mAh

I'd be careful with the Anker Astro 3. The technical descriptions from Anker on Amazon about the Astro 3 and 3e state in bold print: "Please note Astro3 [3E] is not compatible with Asus Tablets."

On the other hand, the EasyACC 12000 mAh unit is advertised on Amazon as being compatible with the Nexus 7, and the reviews indicate that it works for this tablet with the supplied cable. The Easy ACC input is 5V, 2A, so one can use the Nexus 7 plug-in charger to charge it up. According to the reviews it can fully charge the Nexus 7 twice and still have enough juice to charge other phones, etc. It has 4 output ports, including one outputting 2.1A for the Nexus 7.

I've ordered one of these and will report if I experience any problems.
