External battery backup

[primetime34]

I am looking for an external battery backup for the Nexus 7 so I can charge it on a long international flight. Any suggestions?

Take a look at this from pack from Newtrent.

Apple the new iPad Battery Pack - iPhone Battery Extender IMP1000 | NewTrent.com

They focus on the iPhone/iPad market but this one shows as compatible with the Nexus 7

I've had a battery case and an external pack from Newtrent for a couple of years. Both still work very well for my old iPhone 3gs.

Nexus 7 need 2A to charge,indeed many external battery backup cann't meet the 2A output,so cann't charge for Nexus 7.But this one can charge for it,you can take a look at it:Amazon.com: RAVPower Dynamo-On-the-Go RP-PB02 External Battery / Power Bank Charger (4800mAh 2A output), with 1W High power Flashlight for iPhone 4/4S/3GS, iPad, iPad 2, the New iPad (iPad 3), iPod Touch/Classic/Nano; HTC: One X, Sensation/XE/XL, Rad

The N7 can and will charge at lower rates, albeit more slowly. The amperage is certainly worth considering when buying a portable charger, though, and unless there's a huge price difference, not getting a 2a would probably be silly.

I've tried both the 5200ma and 8400ma Powergen packs, they work fine with both the Nexus 7 and the Galaxy Nexus.

I emailed them directly to see which models they could confirm with the Nexus 7 since it wasn't all clear on the site. Here's their response:

These are 12000, 11000, and 9900 mAh backups respectively, starting from about $62, with even the smallest having more than 2x the capacity of the built-in battery. That's a lot of reserve power, and they don't look to be too large.

Most recommendations made on the above posts are two years old.

Any newer, better packs out there...?

Some of the above mentioned can be had relatively cheap - older models, or just lesser performance?

My interest is to get enough supplemental juice for a day in the field, with intermittent use of GPS.
