Two-pack 4-port 12 V charger

This pack contains two identical 12 V USB chargers, each fitted with four ports. Every unit delivers up to 78 W total output from two 30 W PD 3.0 ports and two 18 W QC 3.0 ports. The waterproof design suits marine, motorcycle, RV and golf-cart installations as well as standard automotive use. A push-button switch cuts power to all ports to prevent battery drain when the engine is off.

Ideal for multi-device vehicles

Drivers who need to charge two phones and two tablets simultaneously will benefit from the four-port layout and 78 W shared budget. Boaters and riders requiring a sealed 12/24 V socket replacement are also well served. Buyers who only ever charge a single device or who need a higher single-port output than 30 W should look at something else.

78 W shared across four ports

Each PD port can push 30 W, taking an iPhone 15 Pro from 0 % to 65 % in 30 minutes, while each QC port peaks at 18 W for 0 % to 60 % in 35 minutes on typical Android handsets. When all four ports are active the 78 W ceiling is divided between them, so simultaneous fast charging of four large tablets will hit the shared limit.

Questions about this item

Does this charger need a 12 V or 24 V DC socket to operate?

It installs in any DC 12 V or 24 V vehicle socket, so a car, boat, motorcycle, RV or similar 12/24 V system is all that is required.

Will the two 30 W PD 3.0 ports and two 18 W QC 3.0 ports still fast-charge my older phone that only supports QC 2.0?

Yes, the ports are backward-compatible with QC 2.0 and 1.0, so an older QC 2.0 phone will still charge at its maximum supported speed.

How can I confirm the 78 W total output is active after I wire the unit and press the power switch?

Connect devices to all four ports; the combined draw will reach up to 78 W and the push-button LED shows the circuit is live.
