Instead of the sane approach of specifying 5, 9, 12, 15, and/or 20 volts and the amperages, products insist on listing every model of device in existence instead.

Most will do 12V, but I always want to make sure it’ll power my laptop (20V) as well.

A big thank you to reviewers who post images of the actual products where it shows the relevant info in one short line on the labels:

e.g. PD Output: 5V=3A, 9V=3A, 12V=3A, 15V=3A, 20V=3A

      Should be, but not all of them support 20V. I’m less concerned with the wattage (I usually buy a minimum of 20W) since my laptop is designed for 45W but is smart enough to throttle and not charge the battery if supplied with less. I’ve tested it down to 20W (which the BIOS warned me about) and it works about the same as when it’s in “Battery saver” mode. However, if I put it to sleep or power it down, it’ll charge from 20W just fine.

          Oh, well, silver lining: the misinterpretation of that comment inspired more discussion than it would have had it been interpreted correctly as grammar pedantry lol
