USB-C and QC 3.0 are not bounded.
I think most people are not ready to pay extra $15-20 for modern internal charger with Q.C. support board chip or with extra intrenal dc-dc boost converter to make usb charge real with serial cells connection.
In this case, you can look through single 26650 lights with internal usb charger. Recently were discussed here: Which is the best ~100-220 gram >=3000 lumen light?
Bigger lights dont offer usb charging, there is no much sense in having charger that require 6-8 hours for full charge.
P.S. You can try to repiet such mod or ask builder to make one for you… Noctigon Meteor M43 USB Rechargeable
