DETAILS
Overview
Twin USB charging socket, 3.1A
A tough, simple twin USB-A socket for your dash, battery box, canopy, caravan or boat. Two ports share 3.1 amps: a 1A port for phones, GPS units, headlamps and torches, and a 2.1A port that charges tablets and larger phones at full speed. It runs on any 12V or 24V system, a blue LED shows when it has power, and a hinged cap keeps dust and water out of the ports.

Which one is right for you? All six fit the same 29.2 mm hole, so you can upgrade an older socket without re-cutting the panel.

Two ports, two jobs
| Port | Output | Max Power |
|---|---|---|
| USB-A (top) | 5V / 1A | 5 W |
| USB-A (bottom) | 5V / 2.1A | 10.5 W |
| Both together | 5V / 3.1A total | 15.5 W max |
Plug a tablet or a large phone into the 2.1A port and a smaller device into the 1A port to charge both at once. This socket gives standard 5V charging; for fast charging of the latest phones and laptops, see the QC 3.0 and USB-C PD sockets in the comparison table above.
Tested for vehicle life
Every socket in our range is built to the same factory test standard, so it holds up to dust, damp and corrugations, not just a clean office desk:
- ✓Low contact resistance (under 100 mΩ): less power lost as heat in the port, so more reaches your device
- ✓Firm plug grip: plugs push in with under 1,000 gf and need up to 1,500 gf to pull out, so a cable stays put on rough tracks
- ✓Salt spray tested: 8 hours minimum in 5% salt fog, for boats, beach trips and coastal caravans
- ✓Impact rated to 8 kgf: takes a knock from a boot, bag or esky lid
- ✓Hinged weather cap: keeps dust and water out of the ports when not in use
- ✓Rated -25°C to +85°C: handles a hot dashboard in summer and frosty mornings in the high country
Fitting
- ✓Hole size: cut a round hole of at least 29.2 mm (a 30 mm hole saw works) in any panel, dash, battery box or canopy wall
- ✓Space behind the panel: allow about 50 mm for the body and terminals, plus room for the wires
- ✓Mounting: push the socket through from the front and tighten the threaded retaining nut from behind
- ✓Wiring: push-on spade terminals marked + and −. Run the positive through an inline fuse close to the battery
- ✓Suggested fuse: 5A on the positive feed
- ✓Blue LED: lights when the socket is powered, so you can find it at night and know it’s live
USB sockets draw a small current even with nothing plugged in. If the vehicle or caravan will sit for weeks, wire the socket through a switch or the ignition, or turn off the battery isolator.
