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.

Sturdy build quality, easy install & best of all it actually charges both phones on fast charge!

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.

I added a charging port in my motor home.

Product was easy to install made out of good material very satisfied with the product using it as a voltmeter in a classic automobile works great

I use it as a replacement for the cigarette charger. So far it has being working great.

Overall happy with the USB power ports, more than enough power for an Echo Auto and a phone charger, and installation was fairly easy. 4 star rating is because it would have been nice for a small courtesy if they had included a pair of T-Tap crimp connectors to get power off wires for the existing aux power port and if it had been a bit smaller to install. Didnt take a lot to ream out the existing spot. Once I had all the tools and connectors needed, it was a pretty quick install and has been working reliably

I replaced my dash cigarette lighter with this on my Volkswagen camper van so I can easily see my voltage on my solar battery bank. A few things to note are that it is not universal and I had to bore out the hole a little with a drill bit to get it into the dash. Also, the fuse (10amp) is not a common fuse and after blowing both fuses that it came with (dont ask) I ended up chopping out the in-line fuse and replacing it with a more standard sized fuse. (still 10 amp but can be found at any auto shop) Another note: The super bright and readable LED amp meter display is great but is always on and that may bother some, especially if it is in the area where you sleep. I taped over it so that when the cover is closed you cannot see any light from the display. Another option is to wire it to a switch that can turn it on and off. I may do this in the future. Overall, it does what it is supposed to do and am satisfied with this purchase.

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.

I added this to my 2015 boat which was technically behind the times - along with a cell phone holder and there you have it! This particular USB offers a battery voltage read out, which seems to be spot on as well. I would surely recommend this to anyone looking for an easy upgrade. A simple hole saw cut and it fits beautifully, and since its well made I expect no issues at all. Get one!

These are great little units. Installed 2 in the upper dash of my 2017 Jeep JKU and 2 in the rear of the center console. No more kiddos arguing about who’s phone needs a cord or cords dangling from front to back. I really wish they would change the connections because three are typically installed in tight spots and every mm counts. I was able to get them to fit but a different connector design would be great. Still A+
