Re: [DMCForum] Ohm's Law

[Samuel <samuel_yahoo@xxxxxxxxxxxxx>]

I havent tried in my car, but was in a friend's delorean and had the 
fuse of my car charger pop while it was perfectly fine in my other 
driver (hyundai accent). I'm guessing it may be normal for that much to 
be coming thru the lighter.
