Hamzan 78W 4-Port Car Charger

This 12V USB outlet delivers up to 78W total output across four ports. Dual PD USB-C ports supply 30W each and dual Quick Charge 3.0 ports supply 18W each. It charges up to four devices simultaneously and is backward compatible with Quick Charge 2.0 and 1.0. Suitable for vehicles with DC 12-24V systems including cars, boats, motorcycles, RVs, ATVs, trucks and golf carts.

Aluminum Alloy Build Thermals

The charger casing is made from advanced aluminum alloy rather than plastic for improved heat dissipation and durability. Anti-scratch technology helps maintain appearance in harsh environments. The integrated blue LED voltmeter display automatically monitors the vehicle battery and electrical system, providing real-time voltage readings when connected to the battery.

Dustproof Waterproof Cap Mounting

Each USB port features a protective cap that is dustproof and waterproof. When the cap is closed it continues to show the current voltage reading. The DIY kit design allows installation in a variety of 12V panel locations across marine, automotive and recreational vehicles. The voltmeter functions only when the unit is connected to the battery.

Questions about this item

How do I install the Hamzan 78W charger and what step is often missed?

Drill a panel hole for the socket, connect the red lead to 12-24V positive and black to negative, then tighten the retaining ring; the blue LED voltmeter only activates once the unit is powered, so verify the display lights before finalising the mount.

What maintenance or replacement will the charger need later?

The protective caps over the two PD 30W and two QC 3.0 18W ports keep dust and water out; inspect the seals periodically and replace a cap if it cracks or no longer snaps shut to maintain the waterproof rating.

What limit appears first during sustained high-load charging?

The 78W total ceiling is reached when all four ports draw maximum current simultaneously — two PD ports at 30W each plus two QC ports at 18W each — so the charger will throttle or cycle if the combined load tries to exceed that figure.
