STANLEY J5C09 Power Station Jump Starter: 1000 Peak/500 Instant Amps, 120 PSI Air Compressor, Battery Clamps $47.09

Stanley Jump starter/compressor combo is on clearance at Walmart, and to my knowledge is a good price. I’ve read that on some units the compressor dies after short use – I’d suggest buying Walmart’s 2 or 3 year warranty for it.
