500W Car Power Inverter DC 12V to AC 110V Adapter with 2 AC Outlets and 2A USB Charging Port

The media could not be loaded. Works great for supplemental power to offset the devices we use a lot of. Free power to the TV and tablets and phones. Can handle 12k BTU AC unit just fine as long as you have a good battery system in. Bluetooth function would be nice if we mounted it in a utility closet or in the camper.

it is a quality product . works great

I have the 1500w Pure Sine Wave Inverter with Bluetooth. 118v with no load 👍. Drops a little to 117v with 450w load 👍. 59.5 hertz which is excellent 👍. 17w parasitic draw which isn't bad for inverter of this size.Best of all, when i hooked to oscilliscope, the pure sine wave stayed true to 600 watts. I didn't push load beyond that, and given this is a budger inverter, I won't be pushing past 1000 watts.Lastly, the Bluetooth is sweet!!! Downloaded app with scan of qr code in manual...hooked right up to dongle without any problem whatsoever. Full readout of all the parameters on app so no need for display on inverter itself. App has on/off capability, and timer to shut down inverter.The only bummer is fan runs continously. Its not real load, but definitely noticable. This is what drops rating to 4 stars.Got at great price at $89!!! Exceptional value for money.

I use this in my construction trailer. Paired with two 100 amp hour lithium batteries, it runs the microwave no problem

We need an inverter for medical equipment when my wife is in the vehicle. The equipment has battery backup but need the batteries when we get where were going. The machine is only 2.5 amps the most i would require is 3.5 amps which should be easy for a 700 watt inverter. I tried about 4 different ones and others would overheat because the fan wouldn't stay on. Or other issues. This one works as it is intended to work.It has been used approximately 5 hrs. now no issues. I have an older inverter in my truck that I have had for years and I can't really understand why that old one never has an issue but all the newer models I was trying did? It's a quality issue of course. We used to just use my truck when we needed a 110 source but life changes. The truck is hader to get in and the 110 source is needed most of the time now. The 12 volt won't charge and run some equipment. Sorry for the long post

Standby power was somewhat high at 50 mA @ ~13 V even when the switch was in the off position. My guess is that it's powering the USB regardless of switch state. Idle state consumed quite a bit of power but it's normal for inverters of this size. Was able to power everything I needed for my treehouse I built for my kids.I had three grips with it:1) Produced a bit of back EMI at 50% power that was causing odd behavior on the devices connected to the same DC bus. With the inverter disconnected and off, the problems would go away.2) I HATE when these cheapo inverter "manufacturers" state the choice is random when it comes to configuration. I wanted the non-Bluethooth version but got the Bluetooth version. My guess is that the other version is sold elsewhere. The Bluetooth dongle is truly useless. It would *occasionally* work, sometimes I could turn it off, sometimes I could turn it on, but the odds of it working correct were low. Same thing with the voltage reading via Bluetooth, it would sometimes work. All the other values were dummy values and would not display properly.3) The biggest problem was that about 50% of the time, the inverter would not shutdown if I turned the switch to the off position. I maybe could have lived with the other issues but this one is a big no-no.I ended up getting a Renogy inverter for more money but far less problems. Wish I had saved time and just bought the Renogy in the beginning.

Helpful to power my laptop in the car on the go.A portable backup source of power for homeschooling. I don't have to have my student miss a class during a power outage.

Great Product
