You'd want to be careful buying anything electrical off Aliexpress. A lot of house fires are caused by cheap usb-plugs that are not certified for Europe. They overheat and go on fire. In America, specifically NY, they're thinking of banning e-scooters because, again, they tend to overheat when plugged in and go on fire. It causes huge problems because people live cheek-by-jowl in apartment blocks/tenements in NY.
