I'd debating whether to get a 3kW Granny cable or a 7kW charge point installed at home. I have a ZE20, so overnight charging is not an issue and it would be handy to throw the granny cable in the boot for short trips away. However, I was wondering what the charge efficiency of each solution is - presumably there is conversion efficiency to consider (which ultimately impacts the total amount of electricity used), but my google skills have failed me in finding what difference there might be!
