Sony's grey CPF10LS 10,000 mAh Portable Power Supply is a USB portable charger that provides on-the-go backup power. It provides four USB ports but only allows you to charge two USB devices at a time if you don't have easy access to an AC outlet.

This charger employs lithium polymer battery technology and has a rapid charge feature that lets your device charge faster than an electrical AC outlet. Featuring a lightweight form factor, this charger can easily be packed into a bag or backpack for travel. It eliminates the need to carry around each original car charger for your individual devices so wherever your path takes you, rest assured that your devices will stay powered and ready to go when you need them.
