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.

Product was as advertised and more sturdy feeling than expected. I’ve had it in use for three days now with an iPhone charger and a dash cam and experience no drop in performance.

Replaced a cigarette lighter. Spliced in new wires. Dedicated usb ports, better than plug adapter.

This is a great size - fits right where the lighter socket was, and is small enough to fit almost any application. The USB chargers seem to work well, so its a bonus having two chargers where the light was. The integrated voltmeter is handy if you sit in the car with accessories plugged in: you can monitor the battery. Wish I had one of these as a teenager - no more run down batteries on make-out point! But, the blue light is BRIGHT. Bright enough that it is a distraction. I had to take it off the motorcycle and put it in the car with some shaded tape over it.

Seems to be a very high quality product. Wiring is thick and has good connectors. Really like the AMP display and USB port cover. Definitely recommend this. I replaced the cigarette lighter in my 1995 Jeep Wrangler, great mod.

I purchased these for our business vehicles. We used tablets for our inventory purposes and they need to be charged on and off throughout each shift. These hold up much longer than the adapters you put in the regular car cigarette lighter and with them securely mounted, they dont get lost like those adapters do.

I have this installed on a boat and so far after about a year and a half its still working good. The LED display is bright enough to see in the sun. The voltage readout is accurate. The USB charging works good and applies enough current for fast charging. I havent seen any corrosion yet. The only issue Ive had is the flexible plastic that attaches the cap recently broke. But thats common in a saltwater and sun environment. For the price its a good product.

All is good with one exception. The voltage reading is only when you turn on the unit and not constant. Some what annoying.

Easy installation, look and works as it should.

Have installed in my travel trailer so I can see battery voltage from the kitchen & dining area without needing to walk into the sleeping area at the opposite end. Was easy to install. The combo of USB and USB-C ports is really nice and I use both all the time. However, the display is really bright and disturbs my wifes sleep, even over the length of the 20-foot trailer with a privacy curtain in place -- so I need to cover it up at night. A way to dim the display would be nice, but would surely add to the cost.

For someone who uses usbs for nearly everything this was so handy, and with fast charging. No complaints at all, having this as a replacement is cool plus I can see it very easily in the dark
