Absolutely GARBAGE!!!!! Made by the same company that makes the $80-$159 Stanley and Everstart jump starters. 1600 amp my butt, I load tested mine and it was around 225 amps. The 110/120v inverter can only handle around 200 watt MAX. If you plug something in that has a 200+ watt startup the inverter inside of it will literally catch on fire. They should be recalled and banned from selling them until this MASSIVE Fire hazard is fixed. Plug something in that draws 200+ watt at startup if you want to test it. Make 100% sure that you do this Outside and near your garden hose because there is Zero overload protection on these units and they will catch on fire.
