Think you've seen it all when it comes to USB powered gadgets? Think again. The USB powered mini microwave is here so grab your Spaghetti-O's and a spoon.

It is the world's smallest, portable microwave and can be powered via a link to the USB port on a laptop computer.

The turquoise device -called the Beanzawave – has been created in partnership with Heinz to allow workers tied to their desks to create a warm snack, or hot drink, to see them through the day.

And the convenience of powering it from a laptop computer means you could tuck into a hot snack while flying on holiday or even on the train.

To date, the device, which stands just 7.4inches tall by 6.2in wide and 5.9in deep, is only a prototype.
