Review on 🔌 KOOSLA Pure Sine Wave Inverter: 300W Power Inverter with 60W PD USB-C, Car DC 12V to AC 110V Car Plug Adapter Outlet by Donald Phillips

This inverter works properly. I like that the outlets are far apart. Exactly what I need for my application as I need to connect two wall warts at the same time. The build quality is excellent. I connected the output to my oscilloscope and the output was a perfect sine wave. My load is very light so the fan never turns on. The inverter works absolutely silently, no hum, hum and other noise. However the quality control could be better, this is a replacement for the first inverter I bought which turned out to be faulty. The case temperature reached over 95 degrees even when switched off. This inverter stays completely cold even when it is on and running.
