Dual-Port Car Charger with 39W Output

The Monoprice 143796 delivers up to 39W total output through one USB Type-C and one USB Type-A port. The Type-C port supplies up to 27W via USB Power Delivery 3.0, while the Type-A port provides 12W. It is compatible with a wide range of iOS and Android phones and tablets, including models such as iPhone 13 and Samsung Galaxy S10. The unit is supplied new with a polished black finish and an LED indicator light.

Plug-and-Play Installation

Installation requires only inserting the charger into a standard vehicle 12V accessory socket; no tools or configuration are needed. The compact form factor sits flush in most sockets, though depth can vary between vehicles. The LED confirms power presence immediately. The main issues reported are intermittent contact in worn or loose sockets and reduced output if the vehicle circuit cannot sustain the full load.

Suited for Multi-Device Charging on the Road

This charger suits drivers who need to power a tablet and a phone simultaneously during a journey. The 27W Type-C port handles larger devices that exceed the capability of 18W adapters. Buyers who require more than two ports, higher single-port wattage for laptops, or a hard-wired installation should look at alternative solutions.

Questions about this item

How do I know the charger is working after I plug it into the 12 V socket?

The built-in LED indicator lights up when the unit receives power, and each connected device shows its own charging icon once the Type C port delivers up to 27 W or the Type A port delivers 12 W.

What comes in the box and what must I supply myself?

The package contains the 39 W dual-port car charger only; you need to provide a USB-C cable for the 27 W PD 3.0 port and a USB-A cable for the 12 W port.

Which version of this charger should I choose for a tablet that needs more than 18 W?

This single 143796 model supplies 27 W from the USB-C port, which exceeds 18 W and can charge power-hungry tablets, while the USB-A port adds 12 W for a second device.
