Using damaged cables or chargers, or charging when moisture is present, can cause re, electric
shock, injury, or damage to your MacBook Pro or other property. When you use the included
USB-C Charge Cable and 61W or 87W USB-C Power Adapter to charge your MacBook Pro, make
sure the AC plug is fully inserted into the power adapter before you plug the adapter into a
power outlet. You will hear and may feel a vibration when it connects.
Prolonged heat exposure. Your MacBook Pro and its 61W or 87W USB-C Power Adapter may

Adapter comply with applicable surface temperature standards and limits dened by the
International Standard for Safety of Information Technology Equipment (IEC 60950-1). However,
even within these limits, sustained contact with warm surfaces for long periods of time may
cause discomfort or injury.
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
sleep with a device or power adapter when it’s plugged into a power source. Don’t operate your
MacBook Pro on a pillow, blanket, or other soft material that can block ventilation openings.
It’s important to keep your MacBook Pro and its 61W or 87W USB-C Power Adapter in a well-
ventilated area when in use or charging.
Never push anything into the ventilation openings, as doing so may be dangerous and cause
your computer to overheat. Never place anything over the keyboard when operating your
MacBook Pro. If your MacBook Pro is on your lap and gets uncomfortably warm, remove it from
your lap and place it on a stable, well-ventilated work surface. Take special care if you have a
physical condition that aects your ability to detect heat against the body.
