DaierTek 12V USB C Car Charger Socket, 12V USB Outlet, 48W PD Type C & QC 3.0 12 Volt Dual USB Charging Socket Port Waterproof with Voltmeter & ON/Off Switch for Car Marine Boat Golf Cart -3Pack

The media could not be loaded. I took these immediately out of the box and hooked up to my DC power station to test their claimed voltages and surprisingly they are very accurate (~.1v) according to my power station and my fluke multi meter. They power my new iPad Pro 12.9 and my iPhone every night and I wake up to full charge on each. I have these installed in my RV next to my bed. I bought a wood hole saw and drilled through the passthrough where I wired them directly into my power block. Wires provided are a little short for what I used them for, but were easy enough to splice and extend. It came with 3 so I have no need to buy more ( I used two in my bedroom on either side of the bed, and 1 in my kitchen. Very happy with them and when I am boon docking it's great to see the voltages of my batteries knowing they are accurate enough.

Looks and works perfect. Good way to keep informed on battery charge too!

Great add on for any vehicle. Gives charge ports for modern chargers without having to have an adapter. Installs easily and love it displays voltage as an accessory battery gauge

I used these to replace cigarette lighters in our vehicles. Make sure to to switch them off when leaving the car if you install them on circuits that are always hot.

Easy to install plugs that have USB A&C ports. Voltage meter is accurate.

Very good item

I used this product on our farm tractors to allow phone charging and free up the other ports for other electronics. This also gives us a visual readout of voltage that is not available on the tractors

Use this in an experimental plane to provide continuous power for an IPAD. Keep the IPAD charged up while using the I PAD
