Ring FM e:Can+ Inverter
Price: £44.99, Type: Charger, Connection: 3.5mm cable
Bulky e:Can+ is an inverter, so it can be used to charge household gadgets. The FM transmitter was strong on signal, but didn’t offer 87.9FM as a preset. There’s a USB connection to plug in your own charger, and a 3.5mm cable is included. Preset list on the back means it’s easy to use. Yet the coiled 12V cable made positioning tricky in one of our cars.
