Power Inverter 350W Ucerami DC 12V to 110V AC Car Inverter with 4.2A Dual USB Car Charger

I wired it directly to my batteries in my fifth wheel to get the maximum output. Wife and I use CPAP machines to sleep so when boondocking it's a life saver. The USB outputs are great, too. However, I didn't know that it will start fussing (beeping) when the voltage drops to about 11 to 10.5 volts and will shut off at some point after that. Anyway we can only sleep a few hours with our CPAP machines before it shuts off. Better than nothing and it lasts longer if we take turns.My complaint is that the instructions are incomplete and never mentioned the alarms and shutdown features. Had I known about those thresholds I would have bought a more robust model. Hence 4 stars instead of 5.The price is great as well as the build and the aluminum housing. Comes with extra fuses, cigar plug in and alligator clips.Conclusively, I have to decide whether to buy a more robust model or add more 12 volt batteries to my system.

Nice quite small inverter, perfect for cellphones and small devices. The ad says it supports 150 watts through the cigarette lighter, but the instructions that come with the package say it supports only 120W. This was not enough to power my laptop. So if you wanna get this inverter make sure your devices work with no more than 120w otherwise you will have to run the inverter directly from the car's battery to be able to use the full 350 watts :/ I'mReturning it since having a laptop in a road trip is vital for my kids lol

Works great, handy to have in the truck for emergencies.

Works like a charm. I can use my heating pad on my back while driving. Perfect for us nurses

work good

It only lasted half a hour charging a drill battery
