Use the rear USB Type-C connectors to supply power to your PC

In addition to the standard ac power adapter, some models came with an included USB Type-C power
adapter. If you take your PC with you for travel or mobile computing, you may carry the USB Type-C power
adapter and use it and either of the rear USB Type-C connectors to supply power to the PC.
Figure 10. Either of the rear USB Type-C connectors can be used for supplying power to the PC
Note: The rear USB Type-C connectors are not designed as the primary power input connector. When the
computer is operating, the power supplied by a USB Type-C power adapter may be insufficient. As a result,
the computer may not operate at its full capacity and the battery charging may stop or is very slow. Use the
standard ac power adapter whenever possible.
If your PC model does not come with an included USB Type-C power adapter, you may purchase a Lenovo-
branded USB Type-C power adapter with the maximum output power of 140 W (20 V, 7 A). Power adapters
with the maximum output power lower than 140 W (20 V, 7 A) should only be used to charge your PC when
the PC is powered off or in sleep mode. Lenovo branded USB Type-C power adapters with the following
listed output powers have been tested and found to work with the PC. Power adapters of other brands with
the same ratings should also work but have not been thoroughly tested.
• 95 W (20 V, 4.75 A)
• 100 W (20 V, 5 A)
• 135 W (20 V, 6.75 A)
CAUTION:
When purchasing third-party USB Type-C chargers for use with the computer, choose a product that
is safety approved or certified. A disqualified charger may cause damage to your computer or pose an
electrical hazard. In many countries and regions, manufacturers or importers of electric chargers can
submit their products to a certification authority or approved and recognized testing laboratories.
Such a product usually carries a mark if it was tested to pass relevant quality and safety standards.
For some countries and regions, this certification process is even mandatory. If you live in mainland
China, choose a charger with the "CCC" mark; for users in many European countries, choose one with
the "CE" mark; for users in the United States and Canada, choose a Listed charger that carries a mark
by one of the Nationally Recognized Testing Laboratories. (for example, the "UL Listed" mark). For
