3 Port 12V USB Outlet Surface Mount Lightweight with Voltmeter, Dual USB C 30W and QC 18W Car USB Port 12 Volt Cigarette Lighter Charger Socket Panel with Button Switch for RV Bus Marine

Upgraded Voltage Display: Building upon our previous 3-port USB panel design, we've added real-time voltage monitoring to track your vehicle's battery health. Stay informed about battery status during your journey for w-o-r-r-y-f-r-e-e driving.

Ideal Choice: This 12V car socket charger features a surface-mount design requiring only a single wire hole for installation—no need for large round holes like most products on the market. If your car or boat dashboard has space for a big or long charger, this 12V USB socket is your perfect solution.

Installation Method: Surface mountable on any flat surface. Drill a small hole for wiring, connect black wire to negative terminal and red wire to positive terminal. Tighten two screws and secure the cover plate.

Dual PD & QC Independent Outputs: Features dual USB-C PD ports and USB-A QC ports. Input Voltage: DC 12-24V. USB-A Output: 5V=3A/9V=2A/ (Max 18W). USB-C Output: 5V=3A/9V=3A/ (Max 30W). Total power output across all three ports reaches 78W.

Independent Anti-Slip Switch: The upgraded 12V USB power outlet features an anti-slip push-button switch to turn power on/off at any time. This design effectively prevents battery drain, extends battery life, and controls the blue voltage display. (Note: The switch has a memory function, automatically resuming the last on/off state after power loss.)

Safe Charging: The 12V USB charger utilizes a nylon housing with scratch-resistant and wear-resistant properties. It includes a flip-up waterproof cover that can be easily operated with one hand, effectively protecting the 12V USB-C port from water splashes and dust. An integrated smart IC chip prevents overvoltage, overheating, overload, or short circuits in connected devices.
