USB-C Female to Square USB Adapter

The eForChina adapter converts a USB-C power source into a square USB plug for compatible ThinkPad, ThinkBook and Xiaoxin laptops. It delivers up to 100W at 5A through a zinc alloy housing measuring 33 by 29 by 7mm. The compact form factor makes it easy to carry in a laptop bag.

Suited for square-port ThinkPad owners

Users with laptops that charge via the rectangular square USB connector can reuse existing USB-C chargers or power banks. Buyers whose devices use barrel jacks, proprietary slim tips or standard USB-C charging cannot use this adapter.

Sustained 100W delivery

The zinc alloy body helps dissipate heat during continuous 100W charging sessions. The short 7mm depth keeps leverage stress low on the laptop port when the cable pulls. No active cooling is present, so adequate airflow around the adapter is required during prolonged maximum load.

Questions about this item

Will the 5 A, 100 W adapter work with my older square-tip charger?

The adapter passes up to 5 A at 100 W through the square USB connector; your existing charger must supply the voltage and current your laptop requires.

Does the 33 mm by 29 mm zinc-alloy housing block adjacent ports on a ThinkPad or Xiaoxin?

At 33 x 29 x 7 mm the adapter is compact enough to sit beside most side-mounted ports without interference.

How can I confirm the 100 W link is active after plugging in?

The laptop should show a 100 W charging rate in its power settings and the battery indicator will reflect full-speed charging.
