[Nexus 7 Accessories] dewiniaid:
Edit: I've edited in a summary of working/non-working chargers on the bottom of this post:

I've read a lot of threads about various chargers not working with the Nexus 7 but not a particularly comprehensive list of those that do, so I figured I'd ask this question:

I'm looking to buy a portable charger/battery pack in the near future. I'm also soon to own a Nexus 7 (I'm in the second wave of Play Store pre-orders, so should be some time this week, so I'd like to find a charger that's compatible with it. I've done a fair amount of Googling (and a decent amount of browsing Newegg...), but the Nexus 7 is too new to be explicitly listed as compatible with most chargers.

Ideally:

- Capable of charging 2+ devices simultaneously. (Though the additional power draw of tablets means many devices can't charge two devices if one of them is a tablet -- that's an acceptable limitation for me).

- Capable of charging at the same time as being charged. (I'd like to use it as a regular wall charger when not traveling.)

- Bonus points if the charger can itself be charged via USB, which then makes it work with existing infrastructure (can charge it off of a laptop, existing car charger, etc.)

Has anybody had luck finding something that works? Considering some of the reports were of iPad chargers not being able to charge the Nexus 7, I'd rather not just assume something works and play the "buy and return until I find something that works" game.

Thanks in advance.

Edit: Summary of working/non-working charges through post #23:

"charger cable" means the cable that came with the charger in question. "Stock cable" means the the cable that came with the Nexus 7. "low power" means not on a high-power charging port (i.e. one meant for charging tablets), likely only when the screen is off.

WORKING (YMMV):

Note: Model names/etc below are only as specific as the original post. Links are to the poster who claimed the charger was working or not working. You're encouraged to visit any linked sites/view any posted pictures to ensure the charger being referenced by a poster is the same one you're looking at.

Anker 8000mAh (with charger cable, 2A)

iGo Green 6630079-1400RAV (tested with Samsung Vibrant charger cable, may work with others)

New Trent 5000mAh (conflicting reports, see below)

NewTrent iCarrier 12000mAh (44.4Wh) IMP120D (use included "Galaxy Tab" cable/adapter on 2A port)

New Trent IMP100P (charger cable only)

New Trent IMP1000 (charger cable only)

NewTrent IMP99D (charger cable only)

Poporta Usb Turbo Charger 5000 (charger cable only)

RAVPower Dynamo-On-the-Go RP-BP03 5200mAh Power Bank (charger cable only, only with screen off)

TomTom Universal High-Speed Multi-Charger (low power only)

Yoobao 11200mAh (with charger cable)

NOT WORKING:

There's been a lot of evidence that suggests that charger compatibility may be more a case of what cable you use moreso than which charger you use, and that any true 2A charger will work with the correct cable. That said, these have been explicitly listed as not working by some posters. Again, YMMV.

New Trent 5000mAh (conflicting reports, see above)

New Trent 9900

XPAL 8000
