Ring USB Charging Socket RMS18

Overall Auto Express rating

4.0

Best price: £15.99 | Sockets: 2xUSB

The need to connect to a computer has made USB charging a popular solution for electronic kit, and for many drivers this is the only power source they will need. Many 12V plugs offer exactly that, but this new version from Ring is our pick of the bunch. It comes with two 3.5-Amp sockets for lightning fast charging of two power-hungry devices such as tablets, and it breezed our tests.
