Korea-based company NewQ has recently launched the world's smallest mobile phone charger, the UPlus 2. It is a USB-powered phone charger that almost looks like a little black book. Opening the UPlus 2, reveals 2 USB cables, the first of which you can connect to your computer, while the other one connects to your mobile phone. On top of charging your phone, this USB connection also allows you to transfer files from your phone to your PC or notebook and vice versa.

This nifty little charger is great for people who are always on the go but need to pack light, as the UPlus 2 is also small enough to be carried as a phone accessory. Unfortunately, it is currently compatible with Korean phones at the moment, but the company has expressed intentions to launch to launch a new model that will be compatible with 19-pin and 17-pin mobile phone models. At this time, the UPlus 2 retails in Korea for 12,000 Won or the equivalent of around $13.
