4-in-1 USB charger panel with voltmeter

The Nilight 90310G-D panel combines dual USB sockets, a 12 V cigarette-lighter outlet, a green LED voltmeter and an illuminated on-off rocker switch in a single panel-mount unit. It is designed for 12-24 V electrical systems in cars, trucks, boats, ATVs and RVs, giving drivers a central point to charge phones and run 12 V accessories while monitoring battery voltage.

Sustained-load behaviour

The panel is rated for 10 W total output with each USB port delivering 5 V at 2.1 A, while the built-in 10 A fuse protects the wiring from overload during continuous use. The LED voltmeter provides a real-time voltage readout so the operator can verify that the supply remains within normal limits throughout a journey, and the green illumination stays visible in darkness without drawing excessive current.

Installation and common issues

Mounting uses four screws and the kit supplies three connection-wire packs, nine insulated terminals and a wiring diagram for a straightforward panel-mount fit. The plastic enclosure is water-resistant for marine or exposed locations, but the unit is not portable and requires a suitable flat surface and access to a 12-24 V supply; installers should verify fuse rating and wire gauge match the 20 A input rating to avoid nuisance tripping.

Questions about this item

How much heat does the 10 W panel produce when both USB ports run at 3.5 A all day?

The unit draws up to 10 W total; at 12–24 V input the built-in 10 A fuse limits current, so warmth stays low during continuous use.

What wiring must already be in the vehicle for the panel to function?

A 12–24 V DC supply with a suitable fuse block is required; the kit includes three connection wires, nine insulated terminals and four mounting screws for installation.

Will the green LED voltmeter and dual 5 V 2.1 A ports work reliably on a 12 V system that also powers older accessories?

Yes, the panel operates on 12–24 V, shows real-time voltage on the LED display, and each USB port delivers 5 V 2.1 A alongside the 12 V cigarette-lighter outlet.
