12 Volt USB Outlet RV Accessory 12V Marine Switch Panel,
$24.99
Product Overview
This 12 Volt USB Outlet RV Accessory is engineered for marine and recreational vehicle environments, offering a dependable power solution that supports both legacy and modern electronic devices. Designed to integrate seamlessly into standard switch panels found on boats, RVs, campers, and other 12V systems, this outlet delivers reliable performance where it matters most. Whether you’re navigating open waters or exploring remote campsites, this accessory ensures your essential gadgets stay powered without risking circuit overloads or battery depletion.
The dual-output design merges a traditional 12V DC power socket with built-in USB charging ports, eliminating the need for multiple adapters or separate chargers. This smart integration allows users to simultaneously power classic 12V accessories—such as LED lights, dash cameras, or small appliances—while also charging smartphones, tablets, GPS units, and other USB-powered electronics directly from one centralized location. Built with durability at its core, the unit withstands the rigors of off-grid adventures, including exposure to moisture, salt spray, vibrations, and wide temperature swings typical in marine and RV settings.
Key Features
- Dual-Purpose Power Delivery: Combines a standard 12V DC outlet with integrated USB charging ports to support both older and newer electronic devices simultaneously, streamlining power management during travel or operation.
- Marine-Grade Construction: Engineered to endure harsh conditions—resistant to water ingress, corrosion, and thermal stress—ensuring long-term reliability in demanding aquatic and outdoor environments.
- Easy Installation: Designed to fit standard switch panel cutouts (typically 30mm diameter), enabling quick retrofit into existing dashboards or control panels without requiring custom fabrication.
- Secure Electrical Connection: Features robust screw-terminal connections that maintain stable contact even under vibration, minimizing loose wires and intermittent power issues common in mobile applications.
- Compact and Space-Efficient: Saves valuable real estate on crowded dashboards or control consoles while delivering full functionality in a minimal footprint.
- Universal Compatibility: Works with any properly wired 12V DC system—ideal for marine vessels, RVs, campers, trucks, and other vehicles using standard automotive or deep-cycle battery setups.
Technical Specifications
- Input Voltage: 12V DC (compatible with standard 12V marine, RV, and automotive electrical systems)
- USB Output: Standard 5V DC via USB-A port(s); typically provides up to 2.4A total output, suitable for fast-charging smartphones, tablets, and portable devices
- DC Outlet Output: Continuous 12V DC power for compatible low-draw accessories such as LED strips, fans, or navigation equipment
- Mounting Type: Panel-mount with pre-drilled mounting holes; designed for flush installation into standard 30mm circular switch panel openings
- Operating Environment: Optimized for use in marine, RV, camper, truck, and outdoor recreational vehicles—resistant to water splashes, humidity, and temperature extremes ranging from -20°C to +70°C
- Certifications & Safety: Includes built-in protection against over-current and short circuits; complies with basic safety standards for DC automotive and marine applications
Benefits & Use Cases
This 12V USB outlet addresses a critical need for modern travelers and operators who depend on multiple connected devices but face limited power access in remote locations. RV owners can now charge their phones overnight or keep navigation tools active during extended trips without draining auxiliary batteries prematurely. Boaters benefit from the unit’s resistance to saltwater corrosion and splash damage, ensuring consistent power for radios, chart plotters, or emergency beacons—even in rough seas.
Beyond recreation, this accessory is invaluable in professional applications such as fishing charters, survey boats, or utility vehicles operating away from shore power. Its compact size means it fits neatly into tight dash spaces, while the dual-output design reduces clutter by replacing two separate outlets with one efficient interface. Users no longer need to juggle different chargers or worry about compatibility—everything connects through a single, ruggedized port.
The inclusion of both USB and traditional DC outputs makes this product future-proof: it supports legacy 12V gear today while accommodating tomorrow’s USB-C devices (when paired with appropriate converters). This versatility ensures lasting value regardless of how technology evolves within your vehicle or vessel.
Important Notes
This product is intended for use within a properly wired 12V DC system. Installation should only be performed by individuals familiar with basic electrical principles to ensure safe and compliant setup. The unit does not include wiring harnesses, fuses, or mounting hardware; these components may need to be sourced separately depending on your specific application and local regulations.
Before purchasing, verify that your switch panel has an available 30mm cutout and confirm that your existing 12V system can safely supply the combined load of connected devices. Always use appropriate gauge wire for your current requirements to prevent voltage drop or overheating.

Alternative wiring
At first I didn’t like the wiring compared to a similar one I bought. I also didn’t like that the 12v cigarette charger is lit. But then I quickly realized I could wire it differently, so that the USB port was always on, and the rest only turned on with the switch. This way there isn’t constant drain, because the USB port has its own on/off switch built into itself. This was easy to do. As long as it keeps working for a few years, I’m happy.

Fell apart trying to assemble.
Both of the parts that I tried to push wires onto fell apart in the process. The voltage meter also completely fell apart. Return to sender.

Nice little debice
Used this in our off grid cabin. Use a 12v battery for lights. Gives me a status of the charge left in battery

Made correctly, but designed to be panel mounted.
This is pretty well made, it connects easily and securely and the ports have covers to protect them from rain and splashes. The rear connections are not protected from water, and this is designed to be mounted through a panel, where the rear of the panel is not exposed to direct moisture.With that in mind, everything works well, and charges my iphone and ipad, runs additional power for my marine radio and allows me to keep track of the battery voltage on my boat.

The other charge ports are equally as important as RV Manufacturers spend less on comfort and this is a comfort on the road.5 stars for an excellent product with features of major importance.
