USB-C to Big Square Male Power Adapter

This cable connects a USB-C power source to laptops that use a big square male charging port. It is designed for users who need to charge compatible ThinkPad, ThinkBook or Xiaoxin notebooks from a USB-C charger or power bank. The adapter handles power delivery only and does not transmit data. Its 1.5 metre length gives enough reach for desk or travel use.

Replaces proprietary barrel chargers

The adapter lets you leave the original bulky power brick at home and use a single USB-C charger for multiple devices. It is worth switching when you want lighter travel kit or a universal charging setup for USB-C laptops and legacy square-port models alike. The plug-and-play design needs no drivers or configuration. Buyers who need data transfer or video output should look elsewhere.

Sustained charging behaviour

The 4 mm diameter cable carries continuous charging current without a data channel to manage. Heat dissipation relies on the wire gauge and the charger's own regulation. Under prolonged load the connector remains passive, so performance matches the limits of the attached USB-C power source. No active cooling or throttling circuitry is present.

Questions about this item

Will the big-square male plug on this 1.5 m cable fit my existing ThinkPad power brick?

The big-square male connector is designed for notebook adapters that use that specific rectangular power jack, so it matches the port on compatible ThinkPad, ThinkBook and Xiaoxin chargers.

What is the correct way to connect the USB-C end so the laptop actually charges?

Plug the USB-C side into a USB-C power source that delivers enough wattage for your laptop, then attach the big-square male plug to the notebook; the cable carries power only and does not transmit data.

The cable is 4 mm thick — how should I store it to avoid damaging the wires?

Coil the 1.5 m length loosely without sharp bends, secure with a Velcro tie, and keep it in a dry bag or drawer; the 4 mm diameter sheath resists everyday flexing but sharp kinks can break the internal conductors over time.
