A British start-up called SplashPower has come up with technology that can wirelessly charge all of them at once, without having to plug any of them into the mains.

The system is based around a small flat mat that plugs into the main electricity supply and a special module inside a gadget.

“You pick up your phone, drop it on the pad and it charges. The pad does all the thinking for you,” explained David Whitewood, Vice President of Business Development for SplashPower.

The technology developed by SplashPower is based on the principle of magnetic inductive power transfer.
