Note: For models with a dedicated rectangular power connector, the USB-C connector is not designed as
the primary power input port. If it is used as the only external power source, the computer may not operate at
its full capacity and battery charging may be longer than expected. Whenever possible, use the included ac
power adapter to provide power to your computer.
CAUTION:
When purchasing third-party USB-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
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
people living in other countries and regions, consult a qualified electrical engineer for how to select a
safety approved electric charger.
A power plan
