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
Oh I think I get it now. So you can terminate the solar panel with something like this and then charge phones with a standard car charger with PD. I like that idea.
Exactly. Except I’m trying to avoid those kinds of “cigarette lighter” style adapters, but I’ve used them before (which is why I’m trying to avoid them this time around lol).
Yeah, it’s hard to find good ones. You could invert it to 120v AC and plug in a regular charger, but you lose efficiency doing that, not to mention the added danger, weight, and complexity.
