Customers are saying

Customers are delighted by the power output and overall performance of the POWER 500 Watt Power Inverter, as well as the reliable USB charging capabilities. The inverter is also praised for its ease of use in compact vehicles and reasonable price. However, some customers have reported concerns about excessive noise and unusual smells, while others feel the battery life does not justify the cost.

    I wasnt real impressed with this unit. Biggest one they had and was hoping to use it to keep my Cpap machine running overnight. Started out well but didnt last the night. Added 2nd 12 volt deep cyle battery and didnt last much longer. Draw is only a few amps on the Cpap, just think it takes to much 12v to make 120v
