Installing a commando socket at home in order to use this under UK wiring regs would be at least £200-300 + Anything more than 13A that is designed for EV charging needs to have a Pen-Fault detection device, important to avoid a risk that the earth could be different between the ground and the car. By that point there isn't much cost difference to an installed EV charger, that could be more convenient to schedule. Most sockets at work are intended for using with machinery that's indoors, so there is assumed to be a common ground. Using a lead to extend it outdoors does bring in this risk. Some people do argue this risk is low, but it's in our regs to protect us, lots of measures we take are against pretty low risks.
It's a 32A granny. Interesting. If there's a commando SKT at a destination then it's brilliant but they are rare, as you say campers may find it useful. As an alternative to a wallbox at home, we'll you've still got to run the same 32A circuit so why not put a conventional wallbox in - dumb ones mid £300s less the price of the commando outlet you would have fitted. The timer is a bit clunky and imprecise. If you did have a time of day tariff, you'd need to use the car timer to use the whole period and not loose upto an hour from it. With access to the correct power outlet, this is a 32A granny cum wallbox, so why wouldn't you have one. But I never travel anywhere commando 😮 An interesting review, thanks for taking the time to put this together, keep it up.
Without a CT clamp fitted, you risk tripping your main house fuse. You are still going to have a dedicated 32a supply which doesn’t come for free. Not something that I would consider
I can see people making a pigs breakfast of this with a non qualified electrical install and burning out the wire from the consumer unit or worse. Might be useful if you go to campsites often, then it would work as a Super Granny charger.
I've one of these. Simply brilliant and a no brainer ROI.

Good point.

A 7.4kW EVSE isn't going to trip a 100A fuse.

That's a possibility.
