One of my favorite Milwaukee "tools" - it can make good 'everyday' use of extra M18 batteries that otherwise may sit idle for long periods of time.

They're also great for seeing how your batteries hold up over time. With a USB-C power meter, I was able to confirm that every M18 battery I have (including a 6+ yr old 9AH) can legitimately deliver >=85% of their rated capacity.
According to a YouTube video this is not a pure sine wave, it's kind of a messed up square wave.

No reason this should cost so much. Just sell it to me cheap without the battery.

On home depot that's how much they list that kit for before any discounts.

Just remember that you're losing some efficiency in the conversion of 18-20V -> 5/9/15V or whatever USB-C PD voltage you're testing at. Those buck converters are usually around 90% efficient, depending on the amp draw, so 85% of rated is basically near perfect.

I don't have a Milwaukee battery charger. Can I use a type C charger to charge the battery back up?

What is everyone using this for?

Seems like small loads (lights) would be best suited to staying in the M18 family. And M18 and M12 have light and other options that convert to USB 5v 2.1 amp out for phone and other USB accessory charging.

And large loads, like saws or small appliances are too much for the inverter and most batteries.

Even a portable inflator has a M12 or M18 version that isore efficient.

Friend said that he killed a battery by letting it go to zero during power outage. I am not sure if he had factory or one of the off brand fleebay models that are available.

He had to run wires from battery to another battery to get a little power in it before charger would recognize it.

Any issues or experience with running a battery "dry"

No, unfortunately, the USB-C is unidirectional on this one. If you're looking for one with a bidirectional USB-C, and are indifferent on battery platform, the DeWalt DCB094K has it. However, unlike the Milwaukee, the DeWalt does not have AC power, only USBs. You can pick up the DeWalt one for about $65 [amazon.com] without a battery.
