Manufacturers call them so to begin with  :palm:. It depends on what voltage you take, nominal or fully charged. Also if we start nitpicking, septics do not talk, they collect excrements.

The power output of usb-c isn't up to the job in any case, for the bigger batteries and the requirement for fast charging, but apart from that, keep shitty, fragile consumer crap out of my workplace, thank you very much. Also that would require impractical increases of size for batteries or tools. No.

What power tool charger you have that's greater than 240W?

As stated, any fast charger for modern size packs may exceed 240W or 5A. USB-C until recently was limited to 20V - you need 21V to charge an 18V pack. You're also now adding extra connectors to a device already equipped with all the contacts it needs.

You can have a USB-C port on your toy drill you use to assemble Ikea furniture. There is no demand for such on serious tools.

Any modern real power tool with a fast charger. Personal example would be my DeWalt fast charger that does an 18V 5.0Ah battery in 20 minutes. Then there's the DeWalt FlexVolt, not sure what the charge power is on those but it's going to be more than 240W. Pretty sure all the main manufacturers have a fast charger for their pro/pro-sumer grade tools.

The highest current Dewalt charger have is the XR12A, that's 12 Amps at 18V which can charge a 9AH battery in 45 minutes so that would seem roughly analogous to your 5AH battery in 20 mins.

However, a quick cig packet calculation will tell you that 12 amps at 18V is 216W and, if you actually read the spec sheet of the charger,  it only charges to 80% in that 45/20 minutes, a full charge will take a lot longer.

For your reference and to help you not look silly in future, the power formula:

P=VI

Note how I mentioned that IP65 or greater should be exempt, ruggedize it to at least that level and it wouldn't be required to have USB-C charging. That still leaves how to standardize the ones that do go that route, I suppose Qi charging would make sense for the smaller ones. For the bigger ones, some sort of standardized rugged connector would be the way to go.

It seems you were deep frozen in 2017, but hello again and welcome to year 2023! You know, that USB-C thing happened many years ago, and despite your warranted fears, none of that nasty stuff happened, and I have never heard anyone have any compatibility problems whatsoever with USB-C chargers and devices, which are everywhere. I'm very glad your prediction was wrong.
