LIXINTIAN Car Cigarette Lighter Female Socket to DC 5.5mm x 2.1mm Plug Jack Adapter，for Car Charger UPS Battery Backup and Portable Generator-(2 Pack)

While its not these things fault, they didnt work for me since what I wanted to use it for, air pump, seems to require more amps than my 12v adapter provides.

I Like that i can use this item for a portable power station that has a 5.5mmX2.1mm 12 volt output to power 12v Accessories that use a Cigarette Lighter plug Like a portable Electric Fridge,12V DC Air Pump, or any thing that You would normally plug in your cars Cigarette Lighter/Accessory Power Port

Works, thats all it needed to do.

Got them to use with a Grecell solar generator they work.

Was able to power the tire inflator using my battery bank with DC output.

Does what it is supposed to do.

Good for low amps applications.
