In the long list of pointless USB devices, this USB camping lamp and FM radio must surely be challenging for top spot.
Granted, you could have taken a full charged laptop with you into the country – and you might need a lamp and radio. But chances are your laptop isn’t going to get a signal in the wilds of Wales (I know – I’ve tried), so it’s probably surplus kit on that hiking holiday. However, it also works with 3x AA batteries, it’s small (7.3 x 7.3 x 10.0cm) and features an FM radio with auto scan and retractable aerial, not to mention the torch/lamp for those dark nights in the middle of nowhere.
And the best point of all – it’s cheap. Just $12.
