500W Power Inverter Converter DC 12V to AC 110V Car Charger with 4.2A 2 USB Ports Car Power Adapter-Red

With this inverter I run a tv-dvd combo, a laptop, an air fan and 2 lights. All in my sailboat and at the same time.It's quiet, powerful, efficient and easy to connect to the battery bank!Thi is the best choice for low comsumption electronics!

I built a lithium-ion suitcase charging station for camping, and this little guy was the perfect cheap/small inverter for the job. I wanted an inverter that had a toggle switch so that I could leave it in the "on" position and use an exterior main power switch for the station as a whole. The charge side only featuring outlets and USB ports, rather than on-off switch and other gadgets, was also a must. I looked at a few models, but this was the only one with good reviews that checked those boxes.It didn't disappoint upon receipt. I removed the charge-side end cap and installed it directly to the case, which made installation easy and provided airflow at the expense of waterproofing. The fan does seem to turn on with the inverter, but it's essentially silent and shouldn't be an issue. It also has a green LED next to the USB ports to tell you that it's on.This survived our first camping excursion with aplomb, and nary a fault. One issue, however, is that the inverter beeps once voltage drops below 11v, and shuts off at 10v. This would be a rare occurrence when connected to your car, but it became annoying when the charging station battery voltage dropped. My lithium batteries have 3.7 nominal voltage, which is 11.1v in a 3s configuration. In fact, it beeped incessantly for over an hour while when I tested using a portable fan. I reached out to Bapdas to see if I could use a 4s (14.8v) battery, and will update with their response. Otherwise I plan to clip the wire to keep the little guy silent.Included are source wires for both cigarette lighter and direct battery connection, which I haven't used but kept in my camping box as back-up if my station ran out of juice.

Works amazing! Used it to punp up inflatable kayaks as well as a power drill. No issues- note that it takes a second to work after you pull the trigger on power drills and the air pump

Was great while it worked. One of the plugs stopped working after fiew weeks.

I bought this to use during camping trips. Camping is a cheap get-away and this well-priced power inverter keeps everything charged while we're there. We use it to charge our portable fans, phones, string lights, and my husband's laptop in case he needs to dial in when he gets a call from work. It also runs the device we use to inflate our air mattresses. I like that we can have many devices plugged in at once and don't have to fight over who gets to charge their device first. I've only ever had to use the cigarette power plug, but I like that the option is available to hook up directly to the car battery. We live in a hurricane prone state that has had week long power outages in the past. I feel that this could come in handy if that happened again.

It only came with a cable to directly connect to a battery. The cable that connects to a cigarette jack in the car was not included. Thus, I wasted my money since I cannot use this inverter in my car.

Is a good quality product for the money. With bought it for camping and it performed perfectly.

had drove so little in fla last battery went like 7 years but wore it then with inverter(powering a computer hard drive) well if not kill the circuit will drain empty in 3 days parked and kill a cell and well wont hold charge then worse when replace again the glovebox lamp did the same thing and now just add charge a lot had set it in glovebox and car glovebox lamp there didn't work reliably and only knew on a rainy dark day finally out of dry season saw the light with door shut
