Check the On The Road M9 flashlight.
Besides having a configurable UI (3 group modes), it has USB charging (a ring under which you find the USB-C port). Sturdy light, well made. It takes 18650, though, not 21700s.

My review in case you have some questions: “REVIEW”: On The Road M9 – 1x18650 – 1100 lumens – USB-C Charging – 3 UI Groups
