Dual USB 4.2 A charger with 12 V socket
This Dell PT01122 adapter adds two USB ports and a 12 V cigarette lighter socket to a vehicle 12-24 V supply. Total USB output is 5 V at 4.2 A for 21 W maximum. It can charge two phones, tablets, GPS units or dash cams at the same time while still powering 12-24 V accessories such as tyre inflators or coolers.
Check vehicle voltage and wiring
Confirm the vehicle provides 12-24 V DC from the lighter socket before connecting. The unit uses a 16 AWG pure copper cable 16 inches long with a 15 A blade fuse; verify the fuse rating matches the intended load. Ensure the red wire connects to positive and the black wire to negative during installation.
Suits drivers needing USB and 12 V power
Ideal for motorists who want simultaneous USB charging and a working 12 V socket for car appliances. Not suited for buyers who need a higher USB current than 4.2 A total or who require a pure USB-C Power Delivery charger without the 12 V socket.

Questions about this item
Does the PT01122 come with everything needed to install it, or do I need to buy extra wire or a fuse?
The package includes one complete unit with a 16-inch 16 AWG pure copper cable and a 15 A blade fuse already fitted, so no extra parts are required for installation.
Which output version should I pick if I want to charge a phone and a tablet at the same time?
The adapter has one USB Type-A and one USB Type-C port sharing a total 5 V 4.2 A output, letting you charge two devices simultaneously at up to 21 W combined.
What does the 21 W rating actually deliver when the adapter is plugged into a 12 V vehicle socket?
At 12 V the two USB ports together supply up to 5 V 4.2 A, providing 21 W maximum for phones, tablets, GPS units or dash cams while the female cigarette lighter socket can still power 12–24 V accessories.
