Two-pack aluminium USB charger for 12/24 V vehicles

Each pack contains two round sockets built from aluminium alloy with a scratch-resistant finish. The metal body resists overheating better than plastic alternatives. Three ports on each unit deliver simultaneous charging for multiple devices. A blue LED display shows real-time battery voltage while the engine runs.

Integrated switch and waterproof rating suit daily

An on-off button cuts power to all ports and the voltmeter, preventing parasitic drain when the vehicle is parked. The housing is rated waterproof for boat, golf cart, RV and motorcycle installations. Round cut-out mounting replaces a standard cigarette-lighter socket without extra adapters. Aluminium construction withstands vibration and salt-spray exposure.

78 W total output with dual PD 30 W

Two USB-C ports support Power Delivery at 30 W each and one USB-A port supports Quick Charge at 18 W, sharing a 78 W budget across all three. Compatible with PD 2.0, QC 2.0 and earlier 1.0 standards for broad device support. Buyers needing more than 78 W combined or additional ports should consider a higher-capacity distribution block.

Questions about this item

What USB standards do the PD 30W and QC 18W ports support, and what is the total output?

The two USB-C ports deliver up to 30W each via PD 3.0, and the USB-A port provides up to 18W via QC 3.0. Combined maximum output reaches 78W, with backward compatibility to PD 2.0 and QC 2.0/1.0.

What panel cut-out and voltage range does this aluminium socket require?

The round body fits a standard 12V cigarette-lighter cut-out and operates on 12/24V DC systems, making it suitable for boats, golf carts, RVs and motorcycles.

How is the unit wired and which step is often missed during installation?

Connect the leads to a fused 12/24V supply and secure the retaining ring; the common oversight is forgetting to use the built-in power switch to isolate the ports and LED voltmeter when the engine is off, preventing battery drain.
