Bestek Power Inverter MR13013BU inverter review

Best price: £22.99
Continuous output: 300W

At well under £25 and measuring only 12cm long, this will suit many drivers’ pockets and gloveboxes. Uniquely here it has two USB sockets, which are compatible with Apple devices, alongside the 13-amp outlet, plus itworks through the car’s cigar lighter. Admittedly the lead is a bit short, and it only just took all our devices, but for electronic kit this is all the inverter most will need – and at a cracking price, too.
