So how many times has this happened to you? You’re driving down the road (or you’re cruising on the boulevard or what have you) and suddenly - your cell phone dies. (Okay, it’s not exactly sudden since most cell phones will give you an ample “low battery” warning, but it certainly feels sudden). This is no fun. However, if your electronic device charges via USB you might be in luck.

The Portable USB Power Supply allows you to take some USB power with you when you travel around. It plugs into any wall outlet and can simultaneously charge up to two USB devices, but it also charges its own built-in batteries. Then when you take it with you, you’ll have a nice supply of USB power available to re-charge your gadget that has “suddenly” died.
