Charging. Charge MacBook only with the included 29W USB-C Power Adapter, or with other
third-party cables and power adapters that are compatible with USB-C and are compliant with

electric shock, injury, or damage to your MacBook or other property. When you use the included
29W USB-C Power Adapter to charge your MacBook, make sure the USB-C Charge Cable (2m)

Use common sense to avoid situations where your skin is in prolonged contact with a device
or its power adapter when it’s operating or plugged into a power source. For example, don’t
