500W Power Inverter 12V to 110V for Vehicles

500 Watts equals 4.5 Amperes at 120 volts. I used it in Colorado to inflate a large queen size air mattress. When I received the inverter I realized that the cord was not long enough to reach from the tent to the car. I took a 12 foot extension cord with me and the problem was solved. The unit is well built of heavy aluminum. The cord which connects to the battery or the accessory outlet in your car is okay. It looks like the wire gauge is approx. 18 ga. This is more than enough to handle the 4.5 amp, 120 volt output. Attaching directly to the auto battery bypasses your car's fuse box. There is no danger of blowing a fuse. Most accessory outlets (cigar lighters) in cars can easily provide enough current for this unit if the load is appropriate. Check your fuse size to see the capacity of the 12 VDC outlet. For charging ipads and cellphones there is more than enough capacity. For my trip I was looking for a unit that would allow me to use LED lights in the tent or around the car after dark. No problems there. The air mattress pump only required 350 watts. For a submersible one-cup water heater to make coffee in the morning this was ideal. The size and weight were a consideration. My goal was to keep the load in the car to a minimum. This fits that requirement well. It seems to me this unit will last for years. I will be looking for camping items that work on this unit. Lighting, Small cooking pots, etc. It is also adequate to power small soldering irons, radios, TV's. The limitation is mainly lack of imagination. During storms when power is disrupted, it allows you to continue to use your car to charge your phone. If you are caught in a snow drift and have to stay with your car. Have a small submersible heater and make hot coffee or tea using clean melted snow if you have a cup, ground coffee/tea bags and water. Life saver. Also, if you are camping you can also bring soup to a boil. I will continue to explore the uses of this unit when I am driving or camping. I am also considering a much larger inverter for cooking. This is especially useful on Bureau of Land Management lands and National Parks where it is required that you take you trash with you. I am very satisfied with this unit.

When charging heavy equipment is better to connect it directly to the battery, I connected a super tool drill which takes up lot s of power and a 110 v bulb at the same time , worked well, usb ports charge very fast, I recommend this product

It needs to be unplugged each time you shut off the engine( in my vehicle) It will beep when it loses power from the battery after engine shut off. Due to my battery life isn't all that great. But it's a good product and I just need a new battery

Device worked well and was relatively easy to connect either with the 12V utility plug (cigarette lighter) or directly to the 12 V car battery. When turned on the device had a small quiet fan running. Please note that this particular device's AC output is a modified sine wave as opposed to a pure sine wave. Not all electronics can run with modified sine wave power output. Certainly no problem for phone charges and lights but it would not run my small freezer chest. Also the 12V adapter plug was only about 18" long so the device had to remain in the vehicle when it was running.

Muy vien la entrega excelente

Purchase this and mounted it to a 12 V motorcycle battery. Currently using it on the property where there’s no power. Also have used it several times in power outages. Runs very quiet and the USB ports are handy. Charge it from time to time with the battery tender. It gets warm, but not too hot.

This inverter worked for one usage on a road camping trip in the car to power 2 small led lights. Maybe drawing 50 watts each max @ .5 amps per (if that). Went to use it again this last weekend and it kept faulting after 30 seconds or so with the exact same load. Of course this happened a week after the return window closed. So I wasted my money. DO NOT BUT THIS CHEAP CHINESE CRAP.

Very nice, Sturdy, Runs most of the things I need in my desert cabin.

This unit is not a pure sine wave output as advertised, but rather a normal modified sine wave for this price range. In my case this will not matter, but just so you are aware

pour nous éclairé au chalet . très facile d'utilisation

The product came out very good, it was for my brother to use in his car and it served him throughout his trip where he was able to connect all the accessories. El producto salio muy bueno era para que mi hermano lo usara en su carro y le sirvio para todo su viaje en el pudo conectar todos los accsesorios.

I used it to power my modem, router and network drive in case of power outage, ran everything with no issues for a 5 hr test. Also separately used it to power a laptop as a test, again worked well

the only problem is the connections were to short for where I wantd to mount it.
