DC-to-USB-C power conversion

This cable converts a 5.5×2.5mm DC barrel jack into a USB-C power output for laptops, notebooks and tablets. It lets you run USB-C devices from existing DC adapters without replacing the original power brick. The compact design suits desktop, travel and DIY power setups.

Built-in protection and flexible routing

Over-voltage, over-current and short-circuit safeguards keep connected devices safe during charging. The flexible cable eases routing behind desks or inside tight enclosures for custom power projects. No extra software or drivers are required for operation.

Check adapter voltage and device power needs

Verify that your DC adapter voltage matches the USB-C device input specification before connecting. Confirm the adapter can supply enough current for the laptop or tablet you intend to power. The cable only passes power and does not support data or video signals.

Questions about this item

Will the 5.5×2.5mm DC jack need replacement if the center pin loosens over time?

The DC jack is a standard 5.5×2.5mm barrel connector; if the center pin wears or loosens, the cable end itself would need replacing since the jack is moulded onto the wire.

What limits continuous use when powering a laptop from a DC adapter through this cable?

The built-in protection against overvoltage, overcurrent and short-circuit will trip first under sustained heavy load, cutting power to protect the connected device.

Does the cable get warm or draw extra power when running a notebook all day?

The compact flexible cable is designed for steady power delivery; normal operation should not produce noticeable heat or parasitic draw beyond what the DC adapter supplies.
