Description

Overview

Four-port USB charging outlet for 12–24V vehicle and marine systems: two 30W PD ports, two QC 3.0 ports rated 18W, and a voltmeter in the face. Supplied as a 4-port socket with a wiring tail for a fixed panel install.

Specifications

  • Ports: four USB outlets
  • PD ports: two, 30W each
  • QC 3.0 ports: two, 18W each
  • Input: 12V to 24V DC

Purpose

A boat or camper often has one tired outlet for a crew’s phones and tablets. This puts four independent ports in that hole, and the meter shows whether the battery holds up under charge load.

Applications

  • Helm and cabin charging on boats
  • RV, camper and caravan dash outlets
  • Marine fuse-panel and switch-panel upgrades
  • Truck and van cab charging for two drivers
  • Replacing a single 12V lighter socket

How to Use

  1. Split devices between the PD and QC 3.0 ports, then check the cut-out size.
  2. Isolate the battery and run a fused 12–24V feed to the position.
  3. Crimp the supplied tail, keeping polarity correct.
  4. Seal the rear of the socket against spray in a marine panel.
  5. Caution: stay inside 12–24V and the port ratings; a 24V fault carries more current.
  6. Watch the voltmeter under load to spot a sagging battery.
