Haven’t seen an A/C unit say it works from 100-240 volt.No different than the nameplate on the AC unit on the side of the house.
Not likely, but probably not impossible either. Especially if has a rectifier at the front end of the equipment.Haven’t seen an A/C unit say it works from 100-240 volt.
That doesn’t help figuring voltage drop, or even ocp. Should be in watts instead of having to assume 16 amps @100 volts.Yep, switch mode power supply can operate over this large voltage range.
And a docking station would most likely have a switch mode power supply, like most computer equipment. Even if this does not dock a computer.
I agree. Too ambiguous. We can all agree on guessing what it MIGHT mean, but labels are not supposed to allow guessing. I'm surprised that UL allowed that, amkes me wonder if the UL listing is fake...That doesn’t help figuring voltage drop, or even ocp.

So I guess to the minimum letter of the requirement, it is marked with the voltage and INTENDED LOAD RATING in amperes. So I would take that to mean the OUTPUT is 16A maximum, regardless of the input voltage, which makes more sense, but is still lacking (lazy). I picked up my PC Power Supply and it tells me the DIFFERENCE between Input and Output ratings.All power-supply types covered under this category are marked with input and output ratings that include the voltage and intended maximum load rating in amperes.
Yes, with a load like a battery that can accept a wide range of charging currents, a switched-mode power supply could be designed to draw a relatively constant current from an input over a 100-240VAC range. The battery charging current with 240V could then be as much as 240/100 = 2.4 times higher than at 100V. That way the charger could take full advantage of branch circuits that can supply 16A by reducing the charging time when higher supply voltages are available.Yep, switch mode power supply can operate over this large voltage range.
