4.5×3.0mm DC Jack to USB-C Cable

This cable converts a 4.5×3.0mm DC jack into a USB-C output, delivering up to 140W of Power Delivery charging. It supports 5V, 9V and 20V voltage profiles for laptops, phones and other USB-C devices. The built-in protection circuit guards against overvoltage and overcurrent during operation.

Universal Compatibility Benefits

The single cable replaces multiple proprietary chargers by working with laptops, smartphones, power banks and other USB-C gadgets. Its wide voltage support lets one power adapter serve devices that negotiate different PD levels. The integrated safety design maintains stable output across varied loads for daily and portable use.

140W Power Delivery Rating

The 140W maximum output decides whether this cable can charge a specific laptop or high-power device at full speed. Buyers must confirm their power adapter and device both support the required 20V profile to reach this ceiling. Devices limited to lower PD wattages will charge at their own maximum rate instead.

Questions about this item

Will the 4.5×3.0mm DC jack or the USB‑C plug need replacing after heavy use?

The cable has a built‑in protection circuit against over‑voltage and over‑current, which helps prevent connector wear during daily high‑power charging.

What limits the 140W output during continuous laptop charging?

The 140W ceiling is set by the PD negotiation at 20V; sustained loads cannot exceed that negotiated voltage and current.

Does the cable get hot or draw extra power when running at 140W all day?

The multi‑protection design regulates temperature and current, keeping heat and parasitic draw low even at full 140W PD load.
