Want the freedom to use your phone while topping up the battery? This Samsung wireless charger gets it. Just pop your device on the pad and it'll boost the juice, but if you need to send a quick text, then there won't be any cables getting in the way. Plus, there's an LED indicator that shows when it's fully charged, so you can leave that unlock button alone. It can also hold two devices on at once, which means no more deciding on whether to top up your phone or your earbuds. Heading out to see your mates? Don't worry, the super-fast charge time will make sure your plans aren't delayed. But if you need to leave now, then bring the travel adapter with you, and revive the battery on the go. Please note that this device comes complete with a 3-pin UK plug.
