YONHAN 12V USB Outlet Quick Charge 3.0 Dual USB Charger Socket, USB Cigarette Lighter Socket with LED Voltmeter, Waterproof Aluminum Car Charger Adapter DIY Kit for Car Marine Truck Golf Cart RV, etc.

voltmeter is accurate to within 0.1V lets see if its USB outlets lasts longer then its predecessor (a different rand) It will not provide enough current for mu iPad Air old model to run YouTube and increase battery charge at any useful rate. So it’s a disappointment in that regard.

Muy bueno, fácil de instalar

Installed this in my slingshot. Needed extra USB charging ports. Voltmeter was a bonus. Drill 1 1/8 hole saw, then some slight grinding with file or dremel tool and you are home free. Only consideration is the rain cap is open when charging devices. But I probably wouldnt have phone out in rain anyway.

Great speed of charging - 3 amp but there is one slight problem. I installed two and they indicate different voltages. , Whic one is correct or neither?

Any audio devices will have a great amount of noise while plugged in to the charger.

Very good product works great

Used as a replacement to the cigarette lighter in an older Mini Cooper that I had just updated with the addition of a Bluetooth system that works with the original radio. Car is updated to new technology and the power adapter is low-profile, clean and cool compared to a cigarette lighter with a bulky adapter sticking up. The blue voltmeter readout is a plus feature!

I ordered this the first time for my mustang, and liked it so much that I decided to order it for my truck!

I installed this in my boat for phone charging. It looks good and works well.

Installed this in an old car to replace the lighter plug with USB ports. Very well made, works great
