Rare Item Streamlight Piggyback Smart Charger Stinger Type It appears to be a product that allows you to stock spare rechargeable batteries in a piggyback configuration. (Based on AI search) This item was found at home, but the seller is unsure how to use it, so it is being sold as junk. The items in the photos are all that is included. Please refrain from purchasing if you are concerned about the item's condition due to home storage. I connected the adapter and confirmed that it powers on. Regarding the lamp lighting photo, the lamp blinks several times after the power cord is unplugged. The lamp does not light up during normal operation, but since I do not have the light itself, I cannot confirm whether this is normal. Please be aware of this. Please ask any questions in the comments. ● Charger Body MODEL No.75203 Contents written on the body: STINGER* CHARGER FASTIPIGGYBACK" NM MODEL NO. 75203 INPUT: 12-15VDC 6A MAIN OUTPUT: 4.6-8.3 VDC .9A LED STEADY: CHARGING LED BLINKING: CHARGED AUX, OUTPUT: 3.6VDC .14A LED STEADY: CHARGING FOR SAFETY READ MANUAL STREAMLIGHT 30 EAGLEVILLE ROAD EAGLEVILLE PA 19403 ● STREAMLIGHT dedicated AC adapter cable P/N 22667 ※ Price adjustments are made at the seller's discretion and are generally not accepted.
