Tripp Lite 39W Dual USB Car Charger

This Tripp Lite charger delivers 39 watts of total power from a vehicle's 12 V socket. It provides two output connectors: a USB-C port with 27 W Power Delivery 3.0 and a USB-A port rated for 12 W. The adapter suits drivers who need to charge a phone and a tablet simultaneously on the road.

Capacity and headroom

The USB-C port handles laptops, tablets or phones that accept up to 27 W via Power Delivery 3.0, while the USB-A port covers standard 12 W devices. Combined draw cannot exceed 39 W, so two high-power laptops will exceed the adapter's limit. Buyers needing more than two ports or higher single-port wattage should look elsewhere.

Questions about this item

Will the 27 W USB-C PD 3.0 port charge my phone while the 12 W USB-A port powers an older GPS unit at the same time?

Yes, the charger delivers up to 39 W total — 27 W through the USB-C PD 3.0 port and 12 W through the USB-A port — so both devices can draw their rated power simultaneously.

How can I confirm the 39 W dual-port charger is operating correctly after plugging it into my vehicle's 12 V socket?

Connect a USB-C device that supports PD 3.0 and a USB-A device; both should begin charging at their rated 27 W and 12 W respectively, indicating the adapter is functioning as designed.
