Review on 🔋 Leesky Pure Sine Wave 200W Power Inverter: DC 12V to AC 110V/120V Converter with PD 30W USB Charging & AC Socket for Car Laptops and Phones by Cole Dutta

Of course, if I need a pure sine wave inverter, the most important thing is the pure sine wave, otherwise it will be a 1 or 2 star product. Because the price is ($50), while a typical non-sine wave inverter with comparable performance is only about $20 or less. With a few resistors forming a voltage divider (1/5) and a portable CRO, the numbers and waveform can't lie - yes, it's a pure sine wave output. Then I look at the other "features" of this product, unfortunately only one cigarette lighter is "hardwired" to the inverter, there is no power clamp to connect the alligator clips. or other means of power supply. Normally the fuse or maximum output power in a car is only 15A, which means that such a "hard wire" cigarette lighter will limit its output to 200W. Also, the cigarette lighter plug either doesn't have a fuse, or the fuse is also "hardware" in the cigarette lighter. The USB-C PD output is only 30W and no 20V output, so the laptop can only be charged by the AC adapter. It's heavy, bulky and big as you can see. So yes, it works like a pure sine wave inverter, but gives about 2.5 times more than a traditional inverter, some details are not given, for example a flexible power connection terminal, a reduced power USB-C PD connector. If a pure sine wave is all you need and care about, this works great. Size, weight and features can be improved to make it better.
