ALLPOWERS12V-24V DC Car Charger Adapter Car Power Supply Cable - Cigarette Lighter Charger Plug Car Cable to DC 5.5mm x 2.1mm

Very handy for charging power generator from car.

ALLPOWERS recommended this to charge the battery I got from them, the light comes on to show there’s power to the charger but it doesn’t charge the battery I bought from them

Really happy with it, I would definitely recommend it,It's a game changer being able to charge on the go
