Review on BESTEK 150W Power Inverter DC 12V To 110V AC Converter 4 by Joel Wright

I bought this inverter to charge and use my laptop during long car trips. It worked fine when I first bought it; However, on my second longer trip, it started to fail. Now when I plug in my laptop it keeps turning on and off charging so it can't be used. Additionally, it also works with charging one of my USB powered devices, turning charging on and off while my laptop is plugged in. I had high expectations of this device when I bought it and am very disappointed in the quality. .
