I read previous threads about on-board compressors, etc. I received a Husky (Home Depot's brand) Jumpstarter System for Christmas and I think some of you may want to take a look at this. Here's a pic and features:
Instant vehicle startup complete with air compressor and 400 watt power inverter. Unit includes digital readout, built-in 110 volt charger, LED area light and a DC to DC charger.
? 450 amp jumpstarter.
? 400 watt inverter.
? 260 PSI air compressor w/ attachments.
? 12 volt power outlet.
? 3 LED area worklight.
The unit sells for only $89.99. It's rugged, compact (16wx9hx8d), versatile, and can bail you out of many jams as well as providing convenience. Jeez, I sound like a salesman. Anyway, this thing seems pretty cool so far and I thought I'd share it with you.
