Streamlight’s SolarStream is a supplemental solar charging panel for emergency responder and fleet vehicles. The SolarStream helps to offset battery drain from computer systems and other rechargeable electronics when a vehicle’s engine is off, extending battery life and limiting battery-related vehicle maintenance. The charging system works by dispensing up to 1 amp of current to a vehicle’s battery, helping to prevent it from draining completely and reducing the need for jump-starts and frequent battery replacement due to battery drain. The Streamlight SolarStream comes with a five-year limited warranty.
