US power supply manufacturer iGo is aiming to help the planet and save users cash by reducing what it calls 'Vampire Power': energy drawn from devices that are plugged in but not in use.

According to an iGo spokesman who met with PC Advisor at the CES tradeshow in Las Vegas last week, such power drawn from the grid costs consumers $10bn each year in the US alone.

iGo's solution is a range of green-branded power products that sense whether a plugged-in device is drawing power. Should the iGo powerstrip sense that a laptop or phone is in standby, it will stop the power draw, saving cash and electricity.

iGo says its products can be optimised to suit your needs - checking power draw at 15- or 30-minute intervals depending on the type of device. They also include jump start buttons for if you need to quickly power your device.

iGo expects to launch an eight-outlet power device with four USB power points into UK retail in May. There is a review of the iGo Green here.
