You’re looking at about a 2600 milliamp hours and so you’re getting about a full charge on a cell phone or a couple of charges on a camera, stuff like that. Really handy is the flip out USB tip  which means you don’t need a cable to charge the Flips. That’s a whole bunch of convenient. There’s USB output  at about 1 amp. Push on the USB when it’s flipped in and you get a handy battery indicator. It comes in a bunch of really rad colors and an affordable price point of $29.99.
The big brother, the Flip 20, doubles the power,  so you’re looking at 5200 milliamp hours, 2.1 amp output so you’re going to get a fast charge on your gear and then that same great flip out tip. It comes in 2 colors and gives you multiple charges on phones and other USB gear. The Flip 20 is $49.99.
