Yes, there exist many devices that support multiple charging rates. My phone allows the selection of 3 different wired charging speeds, as well as two different wireless charging speeds, selected in software. Unfortunately, due to cost or incompetent engineering, most devices only accept either a few charging configurations, often just one. I didn't realize this as my first laptop with USB-C ports could be charged with any USB charger, even a dumb 5v 500mA phone charger would eventually get the job done over a couple days. I just assumed everything was like this, but unfortunately not. A lot of laptops and cameras will refuse to draw any power at all unless they can negotiate certain configurations.
