Designed for the Strion LED, Strion LED HL and Strion HPL series of flashlights, the Streamlight Strion PiggyBack Charger enables simultaneous charging of a Strion flashlight and a spare battery. The dual power input charging system permits charging through either traditional AC/DC or USB power sources, giving automotive technicians the flexibility of charging their light and spare battery from devices like a laptop or USB port-equipped toolbox. With the security of having a fully charged spare battery at all times, auto professionals can keep working under darkened conditions, doubling a light’s run-time and increasing productivity.
