Two-pack 78W charger for multiple vehicles

This two-pack supplies a 12V USB outlet with four ports rated at 78W total. Each unit provides two PD 30W USB-C ports and two QC 3.0 18W USB-A ports. The set suits owners of cars, RVs, boats, golf carts, trucks or motorcycles who want identical charging stations in more than one vehicle. Buyers needing more than four simultaneous ports per vehicle should look elsewhere.

Sustained output across four ports

The charger delivers its rated 78W continuously across all four ports without speed loss. Smart IC regulation maintains stable current during extended charging sessions. A pre-installed 10A fuse on the positive wire protects against overload and short circuits. The aluminium alloy housing dissipates heat effectively so performance does not throttle under load.

Thermals, noise and power draw

Aluminium alloy construction provides passive cooling with no fan noise. The blue digital voltmeter draws minimal current while displaying real-time system voltage. A translucent rubber cover seals the ports against dust, splashes and moisture for reliable operation in marine or off-road conditions. The unit installs directly to a 12V supply with the included accessories.

Questions about this item

How much heat does the aluminum-alloy body dissipate when all four ports run at the full 78 W for hours?

The aluminum-alloy housing is designed for superior heat dissipation compared with plastic, and a built-in smart IC chip plus a pre-installed 10 A fuse protect against overheating during continuous high-power use.

What must my vehicle already provide for this charger to work?

A 12 V DC power source with a positive (red) and negative wire so the supplied 10 A fuse on the red lead can be connected, plus a panel cut-out to mount the waterproof outlet.

Will the dual PD 30 W USB-C and dual QC 3.0 18 W USB-A ports charge older phones that only support 5 V 1 A?

Yes, the smart IC negotiates down to 5 V for legacy devices while the blue voltmeter continues showing real-time system voltage.
