HOPI-9800 Power Meter Review
I take a look at the HOPI-9800 from #Shenzhen #HOPI Electronic Technology, a meter that displays the supply Voltage and frequency (or "frequence") as well as the Amperage draw, overall power in Watts, power factor, and annual power consumption.
It's a somewhat dangerous contraption that's not all that well put together. And I forgot to even mention the sketchy multi-national power socket.
With thanks to @bigclivedotcom for recommending-ish this thing.
