Nilight 2-Gang Rocker Switch Panel with Dual 4.8A USB Charger and Voltmeter, Blue — 12V–24V Waterproof

Nilight 90116C is a compact, waterproof 2-gang rocker switch panel that combines two switches, a dual 4.8A USB charger and a built-in voltmeter for 12V–24V vehicles.

This all-in-one panel replaces cluttered dash spaces by integrating switching, fast USB charging and a clear voltage readout in a single aluminum housing. Designed for cars, trucks, boats, RVs and off-road UTV/ATVs, the unit fits standard mounting holes and includes night glow stickers for low-light visibility. Robust contacts and a corrosion-resistant faceplate keep it working in wet or mobile environments.

How does the Nilight panel simplify vehicle dash setups?

Instead of adding separate chargers, switches and meters, the Nilight 90116C combines those functions into one neat module. That reduces wiring runs, cuts panel clutter and gives a tidy, factory-like appearance once mounted.

• Two independent rocker switches control accessories without extra housings.
• Dual USB ports provide two simultaneous device charges at up to 2.4A each.
• Built-in voltmeter shows battery or system voltage at a glance.
• Compact footprint fits common dash and panel cutouts for easy retrofit.

Will the dual USB charger power modern phones and tablets reliably?

Yes. The Nilight USB block delivers 2.4A per port (4.8A total), which supports charging smartphones, GPS units and many tablets at faster rates than typical 1A vehicle chargers. Charging speed can vary by device, cable and battery state, but the higher per-port current helps reduce charging time.

• 2.4A available on each USB port for faster charging than standard 1A adapters.
• Total combined output of 4.8A for powering two devices simultaneously.
• Works with a wide range of 5V USB-powered devices and accessories.

How does the integrated voltmeter help monitor my vehicle?

The central voltmeter displays real-time system voltage so you can spot low battery conditions or charging issues before they cause failures. Clear numeric readout helps with troubleshooting electrical loads, alternator performance, or parasitic drains while parked.

• Continuous voltage readout for monitoring battery health and charging status.
• Quick visual check during start-up and while accessories run.
• Integrated into the charger housing for minimal extra wiring or dashboard space.

Is the Nilight switch panel durable and easy to install?

The housing uses strengthened aluminum and well-conductive pins for long service life in mobile and marine environments. Installation is straightforward with the included screws and sticker templates; basic wiring and fuse protection are all that’s required to get the panel running.

• Corrosion-resistant aluminum face for rugged, long-lasting use.
• Includes four mounting screws and two DIY sticker sheets for neat installation.
• Fits 12V–24V systems common in cars, trucks, RVs, boats and ATVs.

Who is this for? The Nilight 90116C panel is aimed at drivers, boaters and outdoors enthusiasts who want a tidy, multifunction dash accessory: someone upgrading older vehicles, adding USB charging to a boat or RV, or consolidating switches and monitoring into a single waterproof module. It’s best for DIY installers and technicians comfortable with basic 12V wiring and fuse protection who want reliable charging and easy voltage monitoring without multiple devices cluttering the dash.
