I did a little test to consider the EV manufacturer advice not to charge via extention cords (cables).
I connected my iMiEV charging from its 'portable' 10A EVSE unit at the end of 100m + 20m + 10m + 10m of extention cables.
The cables were just dumped in a loosely bundle on the ground...
I'm going through the boxes of bits out of my V8 trade in and thinking of what should be in my new imiev toolkit.
The plug spanner and spare spark plug can go and maybe the welding cable jumper leads. The old fan belt is out along with the can of aerostart and the 10 litre gerry can etc.
But...
