Halfords Portable Powerpack 200

BEST BUY Our reigning champ retains its crown – helped by a £10 price cut. It has a raft of features, including a 240V inverter, 12V socket, fluorescent tubes and a compressor, but shows its age by not offering USB sockets. The compressor is effective, and while the gauge was 2.5psi out, the meaty battery performed well – which was just enough to see off the new RAC.
