500W Pure Sine Wave Inverter 12V DC to 120V AC Converter for Home, RV, Truck, Off-Grid Solar Power Inverter with Built-in 5V/2.1A USB, Reliable Cable, Remote Controller

This pure sine wave inverter was on sale and the lowest price for 500 watts. Small cables, spare fuses and a slightly updated model arrived with a usb-c pd port. I've just connected it to a Lifepo4 battery, the green indicator illuminated and it functions with small fan. I will test a higher load and durability but build quality seems good for the low price.

I am always a little sceptic when it comes to the quality and specs claims of anything that was not manufactured by a major brand. After testing this inverter with an oscilloscope and putting it through a load test, I am happy to say that it produces a very nice and stable sine wave and puts out the stated power. Would recommend.

With a 82W load I measured 122V, fan did not turn on and unit was not even warm.Idle power usage was around 4W.When powered off USB is working and is using 1W.USB was able to charge my Motorola phone in turbo mode.On the scope sine wave looked perfect when unit was loaded or unloaded, voltage was the same in both cases. All measured parameters looked fine.I like the cable screw terminals and thick wires that come with it.

Had a power outage. Was able to use my blender that stated 500w to run it with no issues.The unit looks and feels solid, the design of the plugs slightly closer to each other making it a bit hard to plug two plugs (especially if one is a bigger than normal). The fuses are inside and really difficult to get to.

Works well with the two 300 watthour batteries I have. The only issue I have is no low voltage alarm sounds, just instant power loss when batteries die.

I purchased this inverter expecting reliable performance, but after only two months of use, it completely failed without warning. It was running normally and then just died. No reset or troubleshooting has worked.To make matters worse, the seller provides no contact form or useful support information to resolve the issue. I’m now left with a non-functional product and no way to get assistance. Very disappointing—would not recommend.

The most quiet inverter of my four inverters. I can use it while sleeping because the unit's cooling fan doesn't wake me up. When the fan does run, it is more "whoosh" and not an ear piercing scream. And, it has a low no-load consumption which saves battery power. I use this 500 watt unit to run lights and small fans, and then use the louder large load (3000 watt) inverter for tea kettle, space heater, or window air conditioner. Very happy with this unit.

I use this inverter for emergency backup for my garage. Will power my lights and garage door openers. Also great for camping when no electricity is available.
