Innovative flashlight with induction charger. The integrated USB charging function in this case is not operated with a USB port in the light but with a magnetic induction charger; this means that the charging cable is simply held onto the contact surface of the light, which is then charged magnetically. The cable can also be used as a standard Micro-USB cable to charge other devices. The side switch features easy operation and a lockout function. The light is shipped with a li-ion rechargeable battery (18650/2600mAh), magnetic charging cable, cordura pouch wrist strap, spare gasket, and removable clip. Aluminum housing, water-proof as per IPX-8. 5 light levels with (1000/500/150/50/10) lumens plus strobe. Low profile housing socket for candle stand. Head diameter: 2.5 cm. Also operable with 2 type CR 123 batteries. Please note that 18650 rechargeable batteries with flat head (e.g. 09FN928) CANNOT be used in the RC11.
