Satechi Icel

Has anyone been using this with their IPhone 4's? Seems like even when its been properly charged via a powered usb port, I can only get 1.75x charges out of it which is nowhere near its 4800 mAH capacity.

Been using this for about 2 years with an iPhone 3G. It really does charge the phone battery about 1.5 times. And it really does have a long shelf life once you charge it and flick the on/off switch. It's tiny and lightweight. I've never found a need for more than this between hookups to the grid.

Spec-wise, it's only 1800mAh, which is pretty piddly.

For around the same price, you can get an iUp 5400 or Trent IMP500. Both of these should have twice the capacity of the 3G Juice.

(Disclaimer: I've never used either of these, and don't know how reliable/durable they are.)

I use the Energizer/XPal XP4001. It's a 4000mAh charger that also features two USB ports. A little larger than most of the other external chargers, but it's thin enough to slip into my back pocket. It helps when out for a day taking pix and shooting video

I use a Brunton Solo 3.4 which I've been happy with. It's very lightweight, it can charge any device powered by USB (and charges my iPhones quickly), and the battery lasts a long time in storage - I've had it sit in my travel kit for over a month and it was still fully charged when I went to use it. I'd say I get 2+ charges of my iPhone from it, and it's widely available for under $40.
