DC Accessories Panel
Some Vulcan units are equipped with an optional DC voltage power panel that provides QC 3.0
USB and 12Vdc accessory power. The USB connections can be used to power and charge 5Vdc
devices such as mobile phones. The 12Vdc accessory port can be used to power devices such as
radios, food warmers, 12Vdc refrigerators and coolers, air compressors and other devices that
may be powered from a car accessory port. This port is unregulated and the output voltage can
vary from 11.5Vdc - 14.4Vdc.
