The Powerstrap is designed to be a wearable rechargeable battery pack providing quick and easy power for portable electronic devices. There are six Li-Ion polymer battery cells enclosed in a highly water resistant silica gel casing, with ten adaptors for all kinds of gadgets such as mp3/mp4 players, handheld games consoles, mobile phones and much more.

Simply connect your device to the wrist strap via one of the adaptors and continue to listen, watch, call or play without worrying about the battery cutting out. There are four LED lights to display the battery status and Mini USB connection for recharging/discharging.

The Powerstrap takes approximately five hours to recharge and can be used as a primary power source for devices, giving up to three hours talk time or eight hours mp3 use. It also comes in an array of colours including, yellow, green, blue and red, as well as white and black.

Available from January 2010 price £39.99. For further details check out www.powerstrap.co.uk.

Duracell offer several types of rechargeable batteries but my favourite is the super portable pocket charger. You can keep it in your handbag and if you’re ever out and about and your mobile or iPod dies you can charge it up and away you go.  You get up to 100% charge with your Nano and up to 50% with your Blackberry. It comes with 2xAA ultra cells and is available for £19.99.
