Four-Port 78W Charger

This Leelbox charger delivers up to 78W across four USB ports, combining two PD 30W and two QC 18W outputs. It supports PD 2.0 and QC 2.0 or 1.0 protocols for compatible phones, tablets, power banks and other USB devices. The unit suits 12V and 24V vehicles including cars, boats, motorcycles and RVs.

Aluminium Body With Voltage Display

An all-aluminium alloy housing dissipates heat during high-power charging and resists scratches better than plastic alternatives. A blue LED voltmeter continuously shows the vehicle battery voltage so you can monitor electrical system health while driving. The waterproof design protects internal circuitry in marine and outdoor environments.

Fused 60cm Lead For DIY Fitting

Installation uses a 60cm fused power cord with two spare fuses and blue terminals included; connect red to positive and black to negative. The charger replaces a standard 12V cigarette lighter socket and frees up the original outlet for other accessories. It is not suited for installations requiring a longer harness or panel-mount dimensions not listed here.

Questions about this item

How do I wire the 60 cm fused cord to a 12 V or 24 V system?

Connect the red wire to positive, black to negative, and fit the supplied fuse before powering the 78 W charger.

Which fuses protect the four USB ports over time?

The kit includes two spare fuses for the 60 cm power lead; replace a blown fuse with the same rating to restore charging.

At what combined load does the 78 W limit engage during continuous use?

When total draw from the 2 PD 30 W and 2 QC 18 W ports reaches 78 W, output is capped to prevent overheating.
