There's also something called the "Chargie" (chargie.org) which is basically the same capability but connected on the USB side of things. I assume it's Bluetooth controlled, and it seems to have a bunch of other charge control options including rate limiting. Probably a lot more important back in 2019 when they released it, and probably relevant now for people who want more control (or laptop control with one model, though I suspect a lot of USB-PD laptops can cap charge and you might not want the laptop cycling power on and off).
