AC to DC Converter, 100-240V to 12V 10A Power Adapter with Cigarette Lighter Socket and Voltage Display, 2 USB Ports & Type-C, Power Converter for Car Vacuum Cleaner, Car Refrigerator, Inflate Pump

Mainly used for a Power Supply to power a 12VDC Air Pump and a 12VDC Water Pump.

Since most new cars don't have cigarette lighters you may find a need for one.

Cord is a little too long. Have not had the opportunity to use it yet!

I have used this AC/DC converter to connect my vacuum/inflator combo and not have to use the car battery and it has worked really well so far.

Got a little warm to be expected but works very well.

Defective and unable to use. The red digital display blinks between 95 volts AC and 10.5 volts DC. Voltage readings too low to be useful. Tried a tiny rechargeable flashlight in the 12v output receptacle (car accessory output) and it showed a blinking input power from this unit. Would not charge. Digital display smaller than picture - difficult to read. Really looked forward to the potential of this contraption. Consumed 45 minutes of testing, then 45 minutes to return. Used $4.50 in fuel to drive to a UPS return store. Summary: Cannot trust this product to run when received, nor depend on it later if it should work at first. You will likely be further behind for buying it than not buying it at all. Find something made here - the USA, pay a higher price, get something that works. Good luck and let the Force be with you.

very convieniant until it stopped working
