LIFETIME Cars’ Triple Socket (above) is an old design brought up to date, and this is the original version. It has two USB outlets limited to half an Amp each, which rules out charging most tablets. Even phones and frugal gadgets will charge slowly. Things aren’t much better with the 12V sockets, as the peak combined output is restrictive for a three-outlet adapter. But it’s easy to use, an adhesive pad secures the unit in place and the lightly-coiled power lead easily stretches to more than a metre.
