I was using the GB40 model, which was enough power for my car, but when it couldn't start a friend's truck, I decided to get the largest model. I really liked the GB40 so I purchased the same brand but just bigger model. I haven't used it yet but I'm sure it'll work better than the lower model I had. Only thing that surprised me was the size. After using a small gb40, the gb150 looks huge. I didn't think the size difference was going to be that big. But now I could worry less about which vehicles it won't be able to jump start. And the gb150 has a screen that shows the battery power when you connect it.

Never worked. Brand new out of the box. I read all of the instructions, plugged it in to fully charge the unit and it wouldn't take a charge, wouldn't turn on and the light wouldn't stay on for more than a half second. Don't be fooled by the "designed" in the U.S.A it's still "MADE" in China....enough said.

The jump starter works great, helped neighbor start car and he was impressed. My only disappointment was the fact that a charger is not included.I used my cell phone charger which took two days to charge. I would think a charger would be included for the price that it cost, otherwise it is great.

I tried this jumper on a 1999 f650 Cummins engine with dead batteries. Mind you this truck had not been started in 3 years and it was 20 degrees in Chicago that day. These batteries were so dead I had to turn on the manual override on the noco genius to turn on. I had someone crank it over while I tended the noco jumper and OH MY GOD IT CRANKED OVER FOR ABOUT 6 SECONDS AND STARTED! This thing started a truck over with completely dead dual batteries. If you work on diesels and or heavy equipment get this now. It's rare I take the time to review an item but this is a real gem!
