I just bought a cheap compressor (the kind commonly used for filling car tires) and I'm wondering if anyone knows where I could get a converter to power it from household current; I don't want to have to start the car every time I want to shoot.

Compressor specifications:
12V DC, 8A, 96W; plugs into a cigarette lighter

I already bought one adapter which I thought would work, only to find that it put out .5 amps rather than the required 8.

I know these tend to fail fairly quickly. I was just looking for a quick way to power it (since I was absolutely broke).

I'll see what I can do. Thanks for the feedback.

Overheating is definitely a problem with these little pumps, improvising some way of keeping the cylinder cool would definitely prolong its lifespan.

95% of the world^s population look at me funny when i say..anythign really (atleast in switzerland they do, but assuming you havent visited you are clueless about what im saying)...

@JSR: i think in the end it would be best to just buy a compressor, it would be some much easyer, oh and wouldnt lubricating also prevent overheating(if i said that last sentance to a normal person they would declare me as MAD!)

My main problem is that I can't afford a proper compressor.

A computer's PSU is your best bet. Easy to find, can drive large currents...

You could also just buy a lead-acid battery and a charger for it (that .5A thing you got would work well).

Radio shack should have the converter you need. If not, hit AutoZone's website, or whatever the equivalent is in whatever country you live in.
