USB-C Power Metering with the ChargerLAB KM003C

As mentioned by upon_drumhead (https://news.ycombinator.com/item?id=36841141) there are much better devices for this job.

I'd recommend anyone looking for this sort of device to check out the devices on this list here (just the Energy Meters section) https://sigrok.org/wiki/Supported_hardware#Energy_meters

Sigrok support will ensure you have a well supported open specification device that already has alternative software available in case whatever software is bundled with the device turns out to be substandard or eventually unsupported.

I wish they would have compared against the TC66C. It's an amazing bit of kit at a quarter of the cost.
