Redmi says its new phone can be charged in nine minutes at 210W

If you juice something at 210 watts for 9 minutes, you've pushed 31 watt-hours. That's double the storage capacity of even a good-sized battery phone. The 210W is probably a pretty brief peak!

Still very impressive. I wonder how quickly the battery degrades from this. It'd be interesting to know if the user can elect slower charging when connected eith this charger.

Also very much looking forward to high power usb-pd starting to show up! Dunno if that's whats used here but it's a cool future having 240w over common consumer cables. (Yes Extended Power requires new specced cables, but tbh they shouldnt need to be that significantly more expensive).
