The Energizer 84020 12V All-In-One Jump-Start System is a practical buy considering its great features, its ease of use and ease of maneuverability.

Energizer 84020 12VThe product has a 12V, 18Ah sealed lead acid battery which allows it to be stored in any position. Furthermore, the device is capable of delivering 350 CA, making it powerful enough to jump start any vehicle and also to provide power to almost any appliance or gadget.

Aside from being able to jump start vehicles, this device is also equipped with two 12V cigarette sockets that can provide power for 12V accessories. Moreover, these are protected with a 30A manual reset circuit breaker that will prevent your accessories to be exposed to more power than they can handle.

This charger allows the battery to be charged and prevents it from overcharging so that it can be left in the outlet for indefinite periods of time.

Moreover, you won’t have to worry about overheating, for the compressor is thermally protected and it also has a strong output hose, covered with fabric, with a screw-on valve stem coupler.

Customer Reviews


“Had to get back on here and write a review- I bought two of these, one for me and one for my wife. We both used them more than 6 months after purchase to jump our cars and they worked like a charm. Mine saved me one morning when my battery died before work and my wife used it at the airport one night. These are very important emergency road tools to have and this particular brand gets an A+ in my book.”

“Purchased in August 2010. After fully charging it, I placed it in my girlfriend’s trunk (2008 mustang) and forgot about it. Well one year later, last night, she was able to jump start her dead battery without any issue! My only complaint was having to hear her BRAG about how she did it all by herself without calling me :)”
