Draper 400W Inverter 28815 review

Draper 400W Inverter 28815
Overall Auto Express rating

4.0

Best price: £39.32 | Continuous output: 400W

You get plenty of grunt with this well priced Draper inverter, but it does require an earth connected to the car’s shell. Not surprisingly it clips direct to the battery, but the supply is good, easily coping with all five of the devices used in this test at once.

The fan kicks in only when needed, and usefully it comes with spare blade fuses. Less impressive is the USB socket, which unfortunately we couldn’t get to work with our Apple equipment.
