CEE plugs (IEC 60309) are the rugged industrial connectors you recognise by their colour: blue for single-phase 230 volts, red for three-phase 400 volts. You'll know the blue one as the 16A commando socket on a campsite hook-up post, where it delivers up to 3.7 kW. Red goes considerably further: 11 kW at 16A and 22 kW at 32A.

Domestic three-phase is rare in the UK, so red CEE usually means a workshop, farm building, unit or event site. Where you find one, a portable charger turns it into charging as quick as a public AC point. The blue CEE charger covers campsites and single-phase sockets, while the red versions deliver 11 kW or 22 kW.

All three are adjustable from 8A upwards, so you set the current to match the supply. Voldt® connectors are IP67 rated and built for repeated outdoor use, CE, UKCA and TÜV certified with a 3-year warranty.
