500 Watt Power Inverter

Works well. Run at 460 watts (small space heater) for 5 hours. Fan runs but noise level is tolerable. Case gets warm after about 2 hours with MOSFET mounting points warm enough to be uncomfortable to touch for more than 5 seconds (so don’t do that LOL). The rest of the case is warm but reasonably so. For the price this 500 Watt PSW inverter works well. If your application is under 500 watts continuous this compact inverter should work fine. For a step above you might check out the Bestek 500 watt PSW inverter which easily handles 600 watts and stays lukewarm… but for $30 more. If you’re application is PSW under 400 WATTS watts continuous the Cantonape is a good choice. In my case this unit is for a 55 inch OLED TV, a surround sound bar, and a Roku. About 230 watts.

The fan kicks on every few minutes. It will not power a full load. The inverter turns off with the fault light on as it should with an overload. It will charge from the USB ports. The unit is defective does not run a anywhere to a 500W load. I have it connected to a 12v 600Ah battery bank of LiFePO4 batteries. Update: Sept 2025 The company's customer service rep reached out to me since the unit was not working as it should. To make a long story short the sent me a new unit to replace the one that didn't work right. Got the unit today and tested it. It works fine and even powers MUCH more than I was trying to do with the old one. So not everything is 100% all the time but the customer service rep was great and made it right. I am now giving this 5 stars for caring about the people and their products.

Works great but wish I'd have bought bigger. Maybe a 2500 watt

I'd like your R&D design group to improve the sine wave invertor. The fuses should be accessible from the outside of the unit. There should be a ground wire connector from the chassis of the unit to ground to the chassis of a vehicle. The fan should not turn on and beep every time it is powered in and off. Very annoying feature. silicon goop should be applied better to electrical components. AC plugs are to tough to plug in and pull out wires.

I bought this 13 months ago. until last week it sat unopened, waiting for the next power outage. our power went out as the big chill of Jan. 2024 started. this inverter and car battery were used to power fan on fireplace it worked great for 3 hours before power returned. A week later we are at the end of an ice storm power has gone out again, 20 hours so far and another 24 estimated before power restored. this 500 watt inverter worked fine powering the fan on the gas insert for 3-4 hours this morning then shut down with fault indicator. resetting (on\off) will enable it to work 1-2 minutes before next fault failure. the internal smart fan never comes on that I can tell. I tried using an external USB desk fan to blow into the fan port, had same 1-2 min. shutdown. small fan load, less than 30watts, should not overwhelm 500watt inverter.

I purchased the 1500W, which i've installed on my Sail boat, & it has been great! Easy enough to install, also. I highly recommend the product. Amazing Customer Service: I bought the inverter through another Amazon vendor, & it arrived without the manual. I called Cantonape customer service directly, because I did not realize I had bought it through another source. They quickly assisted me, even knowing that I had not purchased it directly through them, by sending the manual via email, AND sending me a complimentary 150AMP Breaker for my inconvenience! ABOVE & BEYOND :-)

Using it camping to power a CPAP breathing machine, from a car battery. Works for 3 nights. The 9volt low battery alarm is annoying, and loud a d shuts off the power but not the alarm. Helpful if you are using your vehicles battery, but not helpful using a stand alone battery camping. I was able to use a small electric heater, but that thing uses up too much power. Nice digital display for voltage of battery and electricity.

Thought Cobra was a good name brand. But two units came with dysfunctional USBC ports. Giving the Cobra company a third try. I almost ordered one more, but, hesitantly got this half price Chinese unit. Wow, solid metal case, bigger power lugs, heavier wiring with bigger copper clips. Photo. Ran blow dryer on low endlessly and effortlessly with car off. Needed car running to add the electric blanket. Way more than just the stated extra 100 watt output. ¯\_(ツ)_/¯ Oh, and AC outlets don't need gorilla effort to insert or remove the plugs. Don't waste your time with the bigger fancy plastic name brand.

Lo estoy usando en un robot con computadoras caras y de momento (un mes de uso) sin ningun problema tiene buena calidad en los materiales. Se calienta un poco pero dentro de lo normal. Buen producto
