DC jack to USB-C cable with LED display

This 21 cm cable converts a 7.4x5.0 mm DC barrel input into a USB-C output with a built-in LED panel that shows voltage, current and power in real time. It supports up to 140 W at 20 V / 7 A and works with laptops, tablets and phones that accept 5 V, 9 V or 20 V profiles. The woven braid jacket resists tangling and adds durability for daily carry.

Check your power source and device voltage

Verify that your DC adapter delivers between 15 V and 20.5 V and can supply the wattage your device needs up to the 140 W maximum. Confirm the target device charges over USB-C at 5 V / 1.5 A, 9 V / 2 A or 20 V / 7 A and that its barrel jack matches the 7.4x5.0 mm plug. The cable is plug-and-play but will not negotiate power if the source or sink falls outside these ranges.

Suits users wanting visible charging data

Ideal for anyone who wants live read-outs of charging voltage, current and wattage while powering a compatible USB-C laptop or phone from a barrel-output supply. Not suited for devices that require a different barrel size, need more than 140 W, or operate outside the 15 V–20.5 V input window. Buyers needing longer reach or a straight USB-C-to-USB-C cable should look elsewhere.

Questions about this item

What comes in the box and does anything else need to be purchased separately?

The package includes the 21 cm USB-C cable with a 7.4x5.0 mm DC jack input and an integrated LED display. A compatible DC power source supplying 15-20.5 V and a USB-C device are required but not included.

Which version or capacity should I choose for my laptop?

This single model supports up to 140 W at 20 V/7 A and automatically negotiates 5 V/1.5 A, 9 V/2 A or 20 V/7 A to match 65 W, 100 W or 140 W laptops.

What does the 140 W rating mean when the cable is connected to my machine?

It indicates the maximum power the cable can pass when the source delivers 20 V at 7 A; actual charging power depends on the device’s negotiated voltage and current.
