Streamlight’s 75205 Piggyback Smart Charger charges an extra Stinger-series battery quickly and intelligently, keeping your lighting tools ready without interrupting your work.

Compact and purpose-built, the Streamlight Piggyback Smart Charger (model 75205) is a standalone charger that plugs into your existing Stinger system to charge an additional battery. It accepts both 5V/1A USB and 12V DC inputs, offering flexible charging speeds and reducing the need to wait for a single battery to recharge. The unit ships without a battery or charging cords so you can pair it with your current Stinger batteries and cables for a tailored setup.
