Best Portable External Battery (recharger) for S3?

[Howardmgm3]

Doing a lot of traveling and I hate trying to find outlets in airports to recharge.
Which of the external portable batteries that are also rechargers do you recommend for the S3?
Thanks....

I use a New Trent 4000mAh external for my gnex. Works well.

The external batter packs put out by New Trent are consistently some of the best around. I use the 7000mAh pack, which is thin (for an external charger) and has two USB ports: 2.1A for tablets and 1A for phones. When fully charged, it can completely charge my S3 about three times before it dies. And unlike some other external batteries, it charges its battery via microUSB, so that's one less dedicated cable/charger to worry about. I've used it with several different phones while traveling in the U.S. as well as abroad, and it's been nothing short of fantastic.

Depending on your needs, New Trent has external battery packs in several different sizes. The 7000mAh was the sweet spot for me in terms of capacity and size, but there's a size and capacity for just about everyone.
