fun discovery of the day: turns out my laptop will happily slow charge overnight to full from the slightly sketchy "5V 2.1A" USB-A port built into a wall socket using a type-A-to-type-C cable; what a world
@eval I once forgot my laptop charger when going into the office and managed to just about sustain charge by plugging into a USB-C port on a colleague’s laptop, so long as I didn’t do anything more strenuous than running a web browser.
