The Dexim Frixbee is a smartphone charger that allows you to replenish the battery of two gadgets at once. Similar in concept to the Powermat wireless charger range, the Frixbee is a neat little charging mat to keep two iPhones or iPods powered up.

The Dexim Frixbee is first connected to a mains supply, where it sucks up its fill of electricity. It then stores the power within the mat, ready to disperse it when it comes into contact with a suitable receiver such as your trusty iPhone. The device needs 3-to-4 hours to fully charge devices and adds just 100g to the weight of your suitcase. 

It costs £79 inc VAT from O2 stores and Sainsbury.
