Dual USB-C PD charger for 12V and 24V vehicles

This NSI accessory adds two 20W USB-C Power Delivery ports and one 18W QC3.0 socket to a car, boat, truck, RV or motorcycle. It draws power from a standard 12V or 24V DC supply and is built with a waterproof cover for exposed mounting. The integrated on/off switch cuts parasitic draw when the vehicle is parked.

Independent fast charging under continuous load

Each USB-C port can deliver 20W simultaneously while the QC3.0 socket supplies 18W, so three devices charge at rated speed without throttling. A 10A inline fuse protects the circuit from overload during sustained use. The extended housing contains additional smart chips that maintain stable output over long journeys.

Check voltage, fuse rating and panel space

Verify the vehicle electrical system is 12V or 24V before wiring the unit. Confirm the 10A fuse rating matches the circuit protection required for the installation. Ensure the mounting location has enough depth for the extended body and that the waterproof cover can close fully over the ports.

Questions about this item

Does the 10A inline fuse and physical power switch prevent heat build-up and battery drain when the charger runs all day?

The 10A inline fuse protects against overloading during continuous use, while the on/off power button stops current draw when the vehicle is parked, preventing battery drain.

Must the vehicle already have a 12V or 24V DC socket to install this charger?

Yes, the unit is designed for 12V or 24V vehicle electrical systems and connects to the existing DC power source in cars, boats, trucks, RVs or motorcycles.

Will the two 20W USB-C PD ports and 18W QC3.0 socket charge older phones and tablets that only support standard 5V charging?

The ports are backward compatible and will safely deliver standard 5V charging to older devices while providing fast charging to newer ones that support PD or QC3.0.
