How many amps can you pull through the 12V outlet?

How many amps can you pull through the 12V outlet?

I like to be able to fix flats on the road. To this end I normally carry a small jack, tire repair kit, and bicycle pump in cars that have no spares, like my Saleen Mustang and now the Tesla.

However, the 20" performance tires used on the Mustang take over 500 pumps to inflate. I imagine the 19" on my forthcoming P85 will take at least 450 or so.

So I'm looking for high quality 12V air compressors. The good ones seem to pull 15-20 amps@12V.

Anybody know what the rating on the Tesla 12V outlet is? Wouldn't want to blow a fuse pumping a tire...

The rating is 15 amps (as is the fuse). You'll need a compressor with something less than 15 amps (12-13 amps would be ideal).

Hm. Wonder how much amperage I could pull from the 12V posts?

Why not buy one of those jump starter/inflators. They run about $50-75 (I got mine at Costco).

My point (above) is that it has its own battery.

There's one in the Tesla store for $50, with a slime kit I think. As Tesla sells it, it should probably work from the 12V outlet. Is that what you are looking for?

Service Centers sell pumps for $50.

Not really. The slime ruins the tire and in my experience the low-end inflators take an absurdly long time to inflate the tire.

The Slime Safety Spair Flat Tire Repair System (70005) is suppose to be both tire and TPMS safe. It takes 7 minutes to pump in the Slime and inflate the tire.

Dramsey,

Get the Tesla inflator. If it's slime ruins either your tire or TPMS, take all of it back to Tesla. It's guaranteed to be safe.
