Nilight 4-in-1 Charger Socket Panel — Dual USB and LED Voltmeter with 12V Outlet

The Nilight 4-in-1 ON/Off Charger Socket Panel combines dual USB charging, a built-in LED voltmeter, a 12V cigarette-style outlet and an illuminated rocker switch into one compact, mountable unit for 12–24V vehicles.

This all-in-one panel is designed to centralize power access in cars, trucks, RVs and boats. It replaces multiple single-purpose sockets with a single, tidy module that includes wiring, mounting screws and a clear wiring diagram to simplify installation. The panel’s LED voltmeter displays real-time battery voltage, while the dual USB ports and 12V outlet supply power for phones, tablets, dash cams, coolers and other accessories.

How does the Nilight panel make charging more convenient?

The panel gathers several charging options into one dashboard-mounted unit so you don’t need extra adapters or loose sockets. The two USB ports deliver reliable 5V/2.1A output each for simultaneous device charging, while the 12V outlet accepts standard cigarette-plug accessories. A lighted rocker switch makes it easy to turn the entire module on or off without unplugging devices.

• Dual USB ports: 5V/2.1A + 5V/2.1A outputs for two devices at once
• 12V cigarette-style outlet for accessories like air pumps and fridges
• Illuminated rocker ON/OFF switch for quick power control
• Detachable panel design to swap or replace sockets as needed

Is the voltmeter accurate and useful while driving?

The integrated LED voltmeter gives a continuous readout of your vehicle’s battery voltage, helping you monitor electrical health without extra instruments. It’s visible in low light and offers a quick reference to spot voltage drops or charging issues while on the move. The display is meant for general monitoring, not for precision laboratory measurements.

• Real-time LED voltmeter for quick battery status checks
• Readable in darkness thanks to backlighting
• Helps detect major drops or charging anomalies early

What safety features protect devices and wiring?

Safety is built into the panel with an in-line 10A fuse that guards against overload and overheating. The included wiring harnesses and insulated terminals help ensure correct, secure connections during installation. Properly installed, the panel reduces the risk of short circuits and protects connected electronics from simple faults.

• Built-in 10A fuse for overload protection
• Three connection wire packs and nine insulated terminals for secure wiring
• Clear wiring diagram included to assist correct installation

How easy is installation and what’s included?

The panel is designed for DIY fitment into dashboards, consoles or custom panels and comes with the primary hardware required for mounting and wiring. A wiring diagram and multiple connectors simplify hookup to existing 12–24V systems. The detachable face allows future swaps or upgrades without replacing the full assembly.
