AC Wall Outlets: The Laptop Power Adapter for home/office can be operated
from any standard wall outlet using the attached AC power cord. After attaching
the appropriate power tip (see the “Tip Selection” section) to the output cable
of the power supply, insert or attach the tip to your device to begin charging.
Power will immediately be delivered to your device whether it is powered on or
not. Generally, if your unit is not powered on, the battery will begin to charge. It
is normal for power supplies to be warm during use. Avoid placing it near heat
sources, direct sunlight, or heat-sensitive materials.
Air/Auto/Boat/RV: If a DC input is required, we recommend the Belkin Laptop
Power Adapter for travel, which supports both AC and DC input.
