The iGo Charge Anywhere Wall Charger/Battery Backup (Universal) is great device for people who travel a lot and / or use their mobile devices extensively. I picked one up from AT&T and use it considerably, especially while I am on a flight and my iPhone is running low on battery which is atleast twice a week. It has two USB ports to charge two separate devices concurrently, however I would recommend saving and using the 'juice' for your preferred device. It could have a little bit more power, but it still provides a good 60-70% charge for the iPhone4. The iGo Charge Anywhere has an internal battery that recharges while the device is plugged into a wall socket. It also functions like a regular wall charger and is compatible with devices that can be charged via USB cables including most devices from Apple/ Blackberry / HTC/ LG / Motorola / Nokia/ Samsung / Sony etc. The device has worked out quite well for me, especially to recharge my power hungry battery draining iPhone. It is small and easy to use, and has indicator lights to disply when it is out of juice or when it is recharging the internal battery. This is a fairly low-priced device which is perfect for business and frequent travelers
