iworkmart 2-Pack 12V 3-Port USB Charger 78W Voltmeter Switch

SKU CH-AD31-T1HSC

A two-pack of 12 V three-port USB chargers with a built-in voltmeter, on/off switch and waterproof cover delivering up to 78 W total output

  • TypeCell Phone Automobile Chargers
  • Dual USB-C ports deliver up to 30W each for rapid device charging
  • USB-A port adds 18W Quick Charge support for legacy devices
  • Combined 78W output powers three gadgets simultaneously without slowdown
  • Built-in LED voltmeter monitors battery health in real time
  • Waterproof cover protects ports from moisture and dust while keeping voltage visible

Dual 12 V marine charger pack

This two-pack supplies a pair of round 12 V sockets, each offering three ports: two USB-C and one USB-A. The units are built for boats, golf carts, RVs and motorcycles where a waterproof, panel-mount outlet is required.

Suits open-cockpit and exposed-mount installs

The IP-rated cover keeps water and dust out while still showing the LED voltmeter, so users who need a permanent, weather-sealed charge point benefit. Buyers who only need a temporary plug-in adapter for a standard cigarette lighter should look elsewhere.

Bundled wiring kit simplifies fitting

Each charger ships with a 23.6 in power lead, two 10 A spare fuses and two blue ring terminals, letting an installer complete the job without sourcing extra parts. The aluminium housing also improves heat dissipation compared with plastic-bodied alternatives.

Questions about this item

What existing 12 V socket size does the round 3-port charger replace?

The round body fits a standard 12 V cigarette-lighter cut-out, so it mounts directly in the hole already cut in your boat, RV, golf cart or motorcycle dashboard.

Can I leave the waterproof cover closed while the built-in voltmeter is running?

Yes, the translucent rubber cover lets you read the LED voltage display even when sealed, keeping the ports protected from water and dust during operation.

How do I confirm the charger is delivering power after wiring it in?

The LED voltmeter lights up as soon as the 23.6 in lead is connected to a 12 V supply, showing real-time voltage so you can verify the circuit is live.
