Amps for 12 volt tire inflation pump
I'm trying to attach an AC adapter to a 12-volt tire inflation pump (the kind that plugs into your car's cigarette lighter), then convert it into a vacuum pump for degassing molds. I tried connecting the only 12 volt wall wart I have and it just barely got the motor moving. I'm guessing that the amperage of the adapter is too low. What sort of amps would this unit need to run correctly? Is it even possible to run this thing from a wall outlet?
