78W Triple-Port Car Charger

This 78W charger combines dual 36W USB-C ports with an 18W USB-A port for simultaneous fast charging of three devices. It operates on 12V or 24V systems, making it suitable for cars, trucks, RVs, boats, and motorcycles. The integrated voltmeter displays real-time battery voltage at a glance. A built-in 10A fuse and rubber cover add protection against electrical faults and weather.

Replaces Single-Port Low-Wattage Adapters

The jump is worth it when you need to charge a laptop and two phones at once without fighting for a single socket. The physical on-off switch cuts all power draw, preventing battery drain during long parking periods. It upgrades vehicles that only offer a basic cigarette lighter with no voltage monitoring. Buyers who need more than three ports or higher per-port wattage should look elsewhere.

Sustained Load With Voltage Monitoring

Under continuous triple-device loads the 10A fuse protects the circuit while the voltmeter lets you watch system voltage in real time. The switch isolates the charger completely so parasitic draw stays at zero when the vehicle is off. The rubber cover seals the ports against moisture and dust during extended outdoor or marine use. Installation uses the pre-wired fused lead for a permanent, low-resistance connection.

Questions about this item

What size panel cut-out does the charger need to fit into a dashboard?

The unit is designed for a standard cigarette-lighter socket opening; no separate panel cut-out dimensions are provided.

How is the pre-wired fuse lead connected and what step is often missed?

Connect the fused wire to a 12 V or 24 V supply, fit the 10 A fuse, then toggle the on/off switch — forgetting the switch leaves the voltmeter active.

Which user-replaceable part protects the circuit and when should it be checked?

The built-in 10 A fuse is user-replaceable; inspect it if the ports stop delivering power or after an overload event.
