Dell 78W 4-Port USB Power Adapter

The Dell SK-001 is a 78-watt 12-volt USB power adapter designed to replace a standard cigarette lighter socket. It provides four ports, two USB Type-A and two USB Type-C, housed in an aluminum alloy body with a built-in blue LED voltmeter. The unit is waterproof and suited for cars, boats, RVs, trucks and motorcycles.

For multi-device charging in vehicles

Drivers who need to charge phones, tablets, GPS units or smartwatches simultaneously will find the four ports and 78-watt total output practical. The LED display shows real-time battery voltage for system monitoring. Buyers who require a mains-powered charger or a unit with fewer than four ports should look at other options.

78-watt total output across four ports

The adapter delivers up to 78 watts combined through two PD ports rated at 30 watts each and two QC ports rated at 18 watts each. This single figure determines how many devices can charge at their maximum speed at the same time.

Questions about this item

What comes in the box and what must I buy separately?

The package contains the 4-port 12 V USB adapter with two USB-A and two USB-C sockets, an integrated blue LED voltmeter, and aluminium-alloy housing. A 12 V vehicle socket or wiring harness for installation is not included.

Which version should I choose for fast charging?

This single SK-001 model delivers 78 W total: two ports support 30 W PD and two ports support 18 W QC. Select it when you need simultaneous fast charging for phones, tablets, GPS units or smartwatches.

What does the 78 W rating mean in my vehicle?

The adapter can supply up to 78 W shared across all four ports from a 12 V input, so you can fast-charge two devices at 30 W and two at 18 W at the same time while the LED shows real-time system voltage.
