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

Works great

Not weatherproof.

Replaced my faulty cigarette lighter in my 99 civic with this product. The car doesnt have a voltage meter within the cluster so this was a perfect solution.

Use for 12v charger replacement

Everyone has a ton of cigarette lighter ports....these are much more useful and easy to change. The cover got in the way so it got cut off. Charges batteries super fast!

Replaced cigarette outlet in my UTV. Quick job, plugs into OEM Kawasaki wiring.

USB charger works fine. The volt meter rocks. I have it on my pontoon. I can see when the solar panel is charging or when my stereo is draining the battery.

True Fast charge for my Note 9. Easy install. Replaces cigarette lighter port. 2X USB ports. Nice voltage readout display too.

Voltage measurement is accurate, but ONLY when not charging using the USB ports. The input wires are quite thin. This unit requires a round hole, not the round with two flat sides that I had previously.

Works great. I use for charging phone and portable speakers while on my boat. I wired through a switch so I can turn it on and off which is convenient when saving battery power. My only complaint was the didn’t send the dimension for the size hole need to install.
