Wagan 400-Watt Power Dome Jump Starter with Built-In Air Compressor and LED Utility Light

• 400 cranking amps jump starter
• 275 PSI air compressor
• 5 built-in LED lights
• 18Ah DC power source
• Rechargeable via the included AC or DC adapters

Many useful features in this design: compact but capable and rugged. A recommended item for emergency power outages, and for general service where portable power is needed: starts dead car batteries, pumps tires, runs 120V tools, etc.

Two design shortcomings I hoped weren't there, keep it from 5 stars #1: it charges from either a wall-wart 12V adapter, or from a 12V cigarette lighter plug. I much prefer a direct 120V power cord connection versus the wall adapter variety. #2 shortcoming: it doesn't have a self float-charge cycle you must limit your charge times manually by unplugging it (battery damage if charged too long). Ach! Still, guess a person could attach his own float-charge unit instead of the supplied 12vdc adapter. But heck, Wagan, design that into it, like the better powerpacks have.

I dont like writing poor reviews and this is the first one I have ever written. My wife left the key on in her 2005 Stratus all night and ran down the battery. What an opertunity to show her my new Wagan power dome

Jump start in action. Freshly charged for 34 hrs and ready to go. Wrong!

Hooked it up, Hit the starter on the Dodge and all I got was click click click click. No start. What was wrong?? I checked it again, and again. Still nothing but clicking. The Power Dome was trying really hard but no luck. I got out my jumper cables and hooked them to my old 1994 chevy pick up and the Stratus took off Zoom Zoom, Zoom. No problem. To say the least I was shocked. The only thing I could think of was the cables on the Wagan are not strong enough to carry the load, I have read in other reviews complaints about the cable connectors. Some even have replaced them because of brakage. If any one has any sugestions what to do Im all ears. Sorry my review was not a good one.

I bought this jumper and fully charged it for a few days. When my car was dead I tried to jump it but apparently this Jumper didn't have enough juice. I then tried my older portable jumper and that was 2/3 charge and that was able to jump my car. I think this one didn't have enough amperage for my car since it was completely dead. This probably works well for most people because their cars aren't fully drained. However if your car is totally drained I would not completely rely on it.

I bought two, one for me and one for my daughter. Neither one had enough power to turn over the engine of a Honda Civic, even after complete charge. I then used the unit only for portable AC power and it basically burned out after a couple of hours use. Now it won't re-charge at all.

I have only had this product for a couple of weeks and have already used it about 9 times. One of these was unbeleivable. Out at our gold claim we had a military truck with 700 gallons of fuel on board in three tanks. Each tank has a 12volt pump on it. We emptied two of these tanks using the Power Dome. Realizing that we had 12volt power on the truck we disconected the power dome and used the truck battery. in just a few minutes the truck battery depleated to the point of failing to run the pump or turn over the engine. The Power Dome had enough power to jump start the truck and still showed 80 percent of it's charge remaining. I bought another one.
