USB Power Port

the charging jack. It can power/charge devices that require 5 Volts up
to 500mA through the use of a user-supplied cord.
Extending Run Time
Extending the run time of Power Dome’s inverter or compressor can be accomplished by
powering these functions from a charged external 12 volt automotive-type battery.
1. Follow the procedure for jumpstarting an engine as far as connecting the cables
checking for correct battery polarity and turning on the Cable Switch.
2. Now the compressor or inverter can operate for an extended time
• The low voltage protection feature will shut off the inverter when the external
and internal batteries discharge to 10 volts.
• The compressor does not have a low battery shut-down feature so the
user must check the Battery Status meter on the Power Dome.
3. After The Power Dome is used in an extended run time configuration, turn off the
compressor or inverter.
4. Turn off the Cable Switch and store the cables and clamps
5. Recharge the Power Dome and external battery as soon as possible
