I’ve been using the APC UPB10 Mobile Power Pack for three months. It costs around $60 (I bought mine from a local big box store) and can recharge most devices that can be charged from a USB source. The Mobile Power Pack comes with USB cable to recharge itself from either a PC’s USB port or an A/C outlet. However, I had to supply the cables to charge my devices (not a problem). The Mobile Power Pack has a standard sized USB plug at its top. I tested it with a T-Mobile SDA (Windows Mobile Smartphone), i-Mate K-JAM (Windows Mobile Pocket PC Phone Edition), and a 5th generation iPod (video). In fact, I recharged all three using the Mobile Power Pack without needing to recharge the Pack itself. The LCD display stripe you see lit up in the photo tells you what the Pack’s charge level is. A fully lit line indicates a fully charged pack.

The unit is small, thin, and light making it perfect for travel. I only wish its own A/C adapter transformer were smaller and had a folding plug. Other than that, this product gets a mobile thumbs up from me.
