Backpacker Magazine's review of Power Practical's lithium 4400 rechargeable USB Battery
I took to carrying the Lithium 4400 in my purse all the time. It’s so small I hardly noticed it, but it saved the day many times.

Backpacker Magazine's review of Power Practical's lithium 4400 rechargeable USB Battery

The inclusion of a good, bright, flashlight makes this a good choice for a battery charger and the charger itself works well! For its size, it has excellent recharging abilities.
