Review on ⚡️ GoWISE Power 600W Pure Sine Wave Inverter 12V DC to 120V AC + 2 AC Outlets, 1 USB Port, 2 Clamp Cables (1200W Peak), Model PS1001 by George Bell

Inverter works great. Use it as an emergency power supply for the boiler. The boiler will not work with a modified sine wave inverter, but will work fine with this pure sine wave inverter. It was disappointing that the picture had an on/off toggle switch, which I needed. The actual switch is a button. The difference is that if you turn on the inverter and then turn off the 12 volt power supply, the push button switch will reset to the "off" position when 12 volts are reapplied. The toggle switch keeps the inverter on. If the 12V power supply is cycled off and on again, the inverter will turn on if the switch was on before the power supply was turned off. The end result was that I had to leave the 12 volt supply on for the inverter even when not in use (the backup power turns on automatically if utility power fails). 4 stars given because the photo was wrong and I bought it for the characteristics seen in the photo.
