Craig, if you paid £160 for a weatherproof cable with a spike then you seriously got taken for a ride.

I've successfully charged at 10A from a Masterplug extension cable like this on many an occasion. I was doing it for 2 months at a colleague's house before work installed a charge point.

Fwiw the extension you've posted is IP54 (waterproof from spray) rather than water proof from Low or high pressure water. I'd feel more comfortable with IPX5 or better still IPX6.

Re my original post, I've ordered an official Vauxhall/Opel charge cable from the link you guys provided.. We shall see how long it takes to arrive.
