Review on Yinleader Inverter Converter Intelligent Display Car & Vehicle Electronics by Marcus Zimmerly

Waste of time. On a good day, it only manages about 500 watts. My Powerdrive 400w competes with this. My similarly cheaper Jupiter 1500 km is better. I gave it a load of 800W and the voltage dropped to 33V. My Jupiter didn't even flinch. I measured the load with a multimeter, below 800W. Maybe I have a bad blockage? More likely, it's a Ponzi scheme where 500-watt devices are sold as 3000-watt devices. The terminals are oddly close together and quite open. The fan never turns off, even when idle, making it a poorly designed security risk.
