[Caevlist] Caevlist Digest, Vol 77, Issue 9

[A V.]

I use a 10 or 12 gauge extension cord with quality ends, never gets hot
with the amperage that my car's charger draws (~8 amps). I would assume
that a good 10 gauge cord will do the trick for any level 1 charger. you
can also check the amperage that the cord is rated for when you buy it, it
may say on the packaging.
