## Description

Powerful 3000A jump starter with air compressor for 8.0L gas/diesel engines. Advanced safety features ensure a safe jump start even with a drained battery.

Review: Multi function and great! - Really good bit of kit! Cheap for me in sales but I would pay full price it’s worth it! Fits under my seat, charges in couple hours, seems to last but I don’t need to use it only for emergencies, torch light is handy! All rounder works. Easy to use.
Review: Works really well. Excellent piece of kit and great value. - Just had a chance to use it for the first time this morning, on someone else's car. It was very simple to connect up and the car with the gutless battery started first time. Very impressed and pleased that I had it. I bought this neat little device to carry around in my EV just in case the 12v battery on that failed (which it never has) and also so that I could jump start other people's cars (I always carried jump leads in the past for this reason, but the EV's 12v battery can't be used with those). I've yet to try starting a car with a completely discharged battery but that seemed like a pretty important feature when I was considering which jump starter to buy. Pros: Simple to use, plenty of power capacity, seems to be solidly built, packs into a tidy little case, has potentially useful additional features (emergency light, powering coolbox, charging phone etc), holds its charge for a very long time when not in use and is very good value for money. Cons: None
