12V USB Outlet, Ollcuz 12V/24V 36W Aluminum Waterproof Dual QC3.0 USB Fast Charger Socket Power Outlet Adapter w/LED Digital Voltmeter for Car, Marine, Boat, Motorcycle, Truck, Golf Cart, etc

Excellent buy. Works like a champ. They scan be used at the same time without issues like the cheap dual chargers.

Purpose: replace the factory cigarette lighter with a more usable dual USB port (2015 Willys Wrangler). Likes: easy to install. I had to use a dremel tool to slightly enlarge the opening. Wiring was simple, I just used the factory negative and positive wires. It took me approximately 30 min. to install in my Jeep. Dislikes: none at this time.

Not bad if youre mechanically inclined.

this is the 2nd one of a different brand that is total junk and DOA out of the box ! im beginning to wonder what it takes to get one thats not DOA. total Chinese junk. I put 12.63 volts DC on it and no meter reading on the front of it and both ports dead. just more Chinese junk. buyer beware. I suspect these are all made in the same factory with different names on them. I guess im off to find yet another one that may or may not be DOA. wish me luck

This is an extremely high quality charger/voltmeter. The shell is made of machined aluminum and anodized vs being painted. It comes with a tight fitting rubberized cover, so you know its doing is job of keeping liquids out, instead of cheap hard plastic which will crack over repeated use. The voltmeter accuracy is great. I tested it against 3 different calibrated multimeters and the voltage read out was with .05 volts which plenty good for all application where this is used/needed. I installed this charger in my car to monitor its charging output after numerous parts store alternator failures. The dual QC 3.0 ports, for me, was a bonus and works as expected(measuring up to 2500ma with my battery monitor app). Installation is very easy if you are looking to replace your factory outlet. The only modification necessary is to slightly enlarge the original mounting hole a tiny bit, which can easily be done with a file or Dremel. I have to also say, not only is this a great charger/ voltmeter, the company has great communication and is a pleasure to work with. I did have some issues with my first order. However, after contacting the seller my problem was quickly rectified. They were very understanding and quickly sent me out another charger, no questions asked. Not only that, they followed up with me a few days after receiving the replacement to make sure everything was perfect. Great customer service, like this, is rare thing now and days.

Excellent product and very useful!

I installed this on my golf cart which had a 12 volt cigarette lighter charge and switch it to USB charger. It is a perfect upgrade

Replaced my cigarette lighter in my truck with this charger. It works great and charges my phone fast. Only thing that I personally do not enjoy is the LED voltage reading is bright compared to the back lighting in my truck. Only downside so far.

Works great!

Works great used it for a homemade jump box and its perfect
