POWER DOME 400 JMPSTRT

Bought this to run a fan on low for craft shows. Was really hot and waited till the last minute to turn it on so it would last for the rest of the day. Much to my disappointment it only lasted 2 hours on a full charge. Not like my last one of another brand. Very disappointed. Will be returning.

Dont buy it if you want to use the air compressor on it. It is about 10x weaker than if I were to blow with my mouth. I bought it to inflate scooter tires when I replace the valve stems and I highly doubt it will even inflate a bike tire seeing as how it wouldn't inflate my air mattress. I held the air against my arm and I could barely feel it. Returning it.

I have tried the DC and AC outlets, light, voltmeter, and air compressor. They all work. So far I have not had a situation to check the jump start. The unit is well designed and well built, My only complaint is not with the unit, but with the shipping. I paid for two day shipping and received the unit after five business days. Also the unit was in a damaged, but intact original manufacturer's box, which was in turn in a cardboard box with no cushioning. The inner box was free to move around, which is probably what damaged it. Such amateurish packaging should embarrass Walmart.

I charged as instructed and tried to start my tractor and it didn't have enough power charge to boost the battery. Had to revert to using a different auto charger. I think I will need a more powerful power booster like at least 600 and up watts. I will utilize this unit to power other items.

It jump started two different cars without any problems. It also topped off my 35" jeep tires pretty quickly. I haven't had time to see if it can handle them from zero to 40lbs. yet. It's a tad bit bulky and the compressor is a bit loud, but other than that it is a nice tool.
