OK,
review update:
The BL-21 light itself and battery pack is fine, this thing works great for a long time
The charger, however, is junk. It already died (only charges to 3.99 volts then stops)
--
so I am keeping the light and will charge it's pack using my Xtar wpII and some gator clips
I cannot recommend this light 100% due to the cheezy charger,
but as a light with a small battery pack (3x18650), the BL-21 is pretty awesome
