USB-C to DC 5.5×2.5 mm adapter

This adapter converts a USB-C power source into a DC 5.5 mm barrel output for laptops that lack USB-C charging. It supports Power Delivery and Quick Charge protocols to negotiate the required voltage. The unit is designed for users who need to power a barrel-jack laptop from a compatible USB-C charger.

Plug-and-play with voltage selection

The cable works immediately when connected to a suitable 140 W USB-C charger. A button cycles the LED display between voltage, current and power readings without interrupting the power flow. The only common issue is using a charger rated below 140 W, which prevents the adapter from delivering its maximum output.

Limited by charger capability

The adapter can request up to 20 V at 7 A, but the actual power depends entirely on the connected USB-C charger. If the charger cannot supply 140 W, the output will be lower and may not meet the laptop’s needs. The fixed 1.5 m cable length also restricts placement between the charger and the device.

Questions about this item

How can I confirm the cable is delivering the correct voltage and current after I plug it in?

The built‑in LED display shows real‑time voltage, current and power, so you can verify the output matches the selected 20 V, 15 V, 12 V, 9 V or 5 V setting.

What comes in the box and do I need to buy a charger separately?

The package contains the 1.5 m USB‑C to DC 5.5 × 2.5 mm cable with LED display; a USB‑C PD charger rated at 140 W or higher must be purchased separately.

Which voltage setting should I select for a laptop that requires 20 V 7 A charging?

Press the button to cycle the display until it reads 20 V; the cable’s PD trigger will then request 20 V 7 A (140 W) from a compatible 140 W or higher USB‑C charger.
