Portable Type-C to Big Square Power Adapter

This new eForChina adapter converts a USB Type-C charger with Power Delivery into a Big Square connector for ThinkPad, ThinkBook and Xiaoxin notebooks. The housing uses PC and metal and measures 51x20x10mm, weighing about 9.5g for easy transport.

For owners of compatible Lenovo ultrabooks

It suits users who want to charge a Big Square laptop from a modern PD charger they already carry. Buyers whose devices lack a Big Square input or who need a charger without PD support should look at something else.

Single specification: output is Big Square.

The adapter only passes power when the source charger negotiates a PD contract; a standard Type-C supply will not work. The connector orientation is fixed, so reversing it prevents operation.

Questions about this item

Does the big-square female port on this adapter wear out after repeated plugging?

The connector uses a metal housing with PC material rated for standard insertion cycles; no user-replaceable parts are inside the 51x20x10mm body.

What stops me from drawing more power than the adapter can pass continuously?

The big-square output port and Type-C input are limited by the PD charger you supply; the adapter itself has no active current-limiting circuitry.

Does the adapter get hot or make noise when left plugged in all day?

At roughly 9.5g with no fan or electronics beyond the passive metal contacts, it produces no audible noise and negligible heat during continuous use.
