When I plug my MacBook Pro charger into the extension lead I noticed I can see it spark through the Extension lead plastic which I thought was a bit odd I also noticed today that the plug pins are burnt. I tried the charger in other extension leads and it does not happen also tried other appliances with that extension lead and it doesn't happen is the charger not compatible with the extension lead in some way
Got a tip for us?

Don't think your supposed to fit the extension lead with the power on/plugged. Plug the extension into the charger, then plug it into the Mac. It may also be a grounding issue depending on the type of plug/socket, equally connecting the computer last should mitigate any arcing.
