OK, this post is a bit off-topic, but here goes. Hopefully this might help out folks who have had the same problem.
I have bought about four
different tire inflators over the years--$50 Slime and Vi-Air inflators, and a $20 Campbell-Hausfield inflator.
I bought the more expensive Slime and Vi-air inflators, hoping to buy more durable ones that
would last a long time and were of better quality than the cheap ones I've had
in the past. Both of these inflators works
well but they both blow the fuses of all my cars -- a 2006 Ford E-150 van, Dodge
Caravan, and Honda Odyssey. The
thing that I don't understand is that there is a fuse in the power cord of the
inflator. Theoretically this fuse
should blow before the ones in my car (which are rated at 20 amps!), but the Vi-Air and Slime inflators both blow the fuses in my cars, and it is a
hassle to replace the fuses.
solved this problem by buying an adapter that I can clamp directly to my car battery. This adapter has a cigarette lighter
female socket on the other end, so it supplies power directly from my car
battery to the tire inflator. I
have had no problems with blown fuses, whether in the car or in the inflator,
since using the car battery directly.
I have a cheaper Campbell-Hausfield inflator that is much louder and
slower to inflate, but it has never blown a fuse in my car.
