The Battery dying in your phone is everyone’s nightmare and it always seems to happen right when you need it the most! USB charging ports are becoming more plentiful these days, but sometimes you are just not anywhere near one. This little gadget from Duracell promises to help fix that.

It is a very simple device. It is basically just a battery with a standard USB port on one end. When you need some extra juice for your phone, iPod or MP3 player, just plug it in using the USB cable that came with your device and turn the on/off switch to the on position. Juice will start flowing into your device immediately. A typical phone with a dead battery will be charged up to about 80%.

But what happens when you exhaust the battery inside the Instant USB charger? Well, fortunately, there is a mini USB port on the other end and it comes with a USB cable that will allow you to plug into a computer or anything else that has a USB port so that you can recharge. Recharging the Instant USB Charger takes about 3 hours to take it from completely dead to full charge.
