Accessory Power Socket - Honda Pioneer 1000 2017 Owner's Manual

The accessory power socket is located in the center of the lower
dash. The socket is intended for 12-volt DC accessories rated for 120
watts (10 amps) or less. Exceeding the limit can blow the accessory
socket fuse (see page 248).
The socket can be used to power such items as a trouble light,
spotlight, CB radio, or cell phone, but not a heat-generating
accessory, such as a car cigarette lighter.
