LiDiVi 2 USB Charger Socket Power Outlet 2.1A & 2.1A with Red Voltmeter LED Digital Display for Car Boat Marine Mobile

I installed this on my motorcycle side panel. Looks great and it is within .1 VDC of my multimeter reading. So I think it is very accurate. Fast charging worked great too with my Samsung phone. The meter is readable with the cap on and is very bright for daytime viewing. I bought this unit mainly because I like to keep an eye on my bike's battery charge level. There's something draining it and I haven't figured out what is causing it yet. By monitoring the voltage I know when to reconnect the charger. I have a lithium battery which replaced the Lead Acid one, and as I understand it, it is best to not use trickle chargers all the time on these types of batteries. I don't know if that's true, but what I do know is that if the voltage gets too low, they are impossible to charge with a smart charger. Thankfully I have an old dumb charger which charges anything regardless of charge level. But it's a pain to have to get to the battery terminals to use it. Now I can simply connect my battery tender as needed without the additional hassle. Hope this helps someone shopping for this type of device.

The dual USB charger with voltmeter was a great purchase to customize my bass boat console, allowing me to remove one of the instrument gauges so that a large fishfinder could be custom mounted where the instrument cluster was! In addition, I can easily keep my phone charged as well as any remotes for the trolling motor (or other)! Installation was easy and all necessary hardware supplied with unit. Considering it is exposed to the environment, the sealing lid is a huge benefit and when closed, you can still read the voltage display through the lid! Highly recommend!Oh, this is one of only a few with dual 2.1 amp ports for fast charging and/or for your larger pads, etc!

I’ve been wanting to replace my useless cigarette lighter in my 2008 Mazda 3 for a while now but never got around to doing it. I did it in about forty five minutes, I think? And it only took so long because this was my first time ever attempting anything like this and I couldn’t find any tutorials on how to remove the lighter socket for my particular car (but that’s an issue with my car not the product itself). After I managed to (finally) remove the lighter, the charger socket just slipped right in and all I had to do was tighten it on the other end. It comes with two blue terminals to connect the wires to your new socket. Easy! I’ve seen some tutorials where this product is too big for the socket hole of certain cars but it fit mine to a T that I just about laughed at how well things were going. Really, if I had opted to not preserve the original housing for my cigarette lighter (“just in case”) and had just snapped everything out, the whole thing would have taken only ten minutes at the most. After I was done I tested it, and it worked perfectly!I bought the red version and it looks really good with the red lighting in my Mazda 3!

Displays car battery voltage which is exactly what I needed for my Jeep Wrangler. And 2 UBS charging ports 2.1 vEdit: JUNK!!!!!Dropping ratings to 1 STAR. This item stopped working after 3 month of usage. I thought it was the digital display that went out, But the USB ports were not charging either. I tested to voltage on the Jeep's harness and the voltage is there but the USB charger stopped working period!

I installed it in a old cigarette lighter hole. You will have to use a 1 1/8th drill bit to complete the job. But way cool on how you can check your charging system. Just remember in different application your stock wiring might be direct off the battery and has power on all the time. Might have to put a switch in or will run down battery.

I purchased one, however the voltameter gave very low readings, inaccurate voltage readings. With all the great reviews, I thought I may have just gotten a bad unit, so I returned it and got another. While the second one did not read as inaccurately as the first, the voltameter reading was still too low.

I am a Over The Road truck driver. I installed this usb port in my truck about 3 months ago. I use it to recharge a tablet and a phone all the time. The voltage readout lets me know what my battery charge is on my truck when I first wake up in the morning. It has worked very good for me. I am happy with it.

Not the highest quality but installed easily and seems to register within .5 volts of my DVOM.
