Q&A's:
"Will my charger for my stinger be the same as the strion hp"
No a Stinger uses P/N 75100 charger, and a Strion HP uses a P/N 74102, they may look the same but Streamlight shows different part numbers for the lights.
"I have a charger and cord for a Stinger... does this Strion charger base work with the Stinger cord?"
The cords are interchangeable.
