Review on ⚡ GoWISE Power 1500W Pure Sine Wave Power Inverter 12V DC to 120 V AC | 3 AC Outlets, 1 USB Port | 2 Battery Cables & Remote Switch (3000W Peak) PS1005 (Brand Name/Packaging May Vary) by Jeff Robeson

Delivery was fast and complete. I tested it and it worked great. I use it as a backup generator for medium power outages (up to 1 day) to keep my work computers running. The modified square wave was not recognized as a valid power source by my UPS (did not charge, this was true for several brands) and I thought I'd try a full sine wave inverter. It worked great and the device is way more powerful than the modded square ones I was able to get my hands on. Now, if there is a power outage (which is common in the mountains of eastern Kentucky), the UPS will run long enough to pull the lead-acid batteries from the cradle and connect the UPS to the inverter with no runtime loss. I used to have to turn off the power and switch all the individual lines straight to the inverter and then vice versa when the power came back. Now I just plug the UPS back into the wall. I only did a test run at full load for 4 hours so I don't know how long-lasting this device will be. The combo draws around 800 watts (I ramped up the inverter on purpose) and the inverter shows no signs of heating - the case stays around room temperature and the fans don't turn on. The no-load current is 10 to 100 mA. There is no display apart from a few LEDs, but separate products for measuring power, battery voltage, etc. can be found quite cheaply.
