Ring RMS15

The RMS15 is one of our favourite 12V adapters, offering two 12V sockets and one USB socket, as well as a single Micro USB on the end of a 60cm retractable cable.

The latter is ideal if you have a gadget like a hands-free earpiece or Android smartphone. However, the coiled power cable which goes into your car’s 12V socket is a bit short compared to the Sakura pair’s, so you won’t be able to mount it too far from your car’s 12V input.

And although the sockets light up when in use, the Ring looks too pricey in this company.
