DC CABLE REQUIREMENTS
DC cable gauge and length requirements
DC power systems have significantly higher losses over cable and this can be exacerbated by
insufficient cable or bad cable joins. When running the Benchy Carbon off battery power it’s
important to understand that longer cable requires thicker cable to avoid excessive power loss. We
recommend pure copper cable (not aluminium or copper plated). The table below shows the
necessary minimum gauge required. It’s ok to use smaller cable but do
not use larger cable than this.

DC Voltage requirements
The voltages in the table below specify the voltage required to the compressor. This does not take
into account voltage loss in fittings such as cigarette lighter sockets, cable joins or the cable itself
that you might have in your system. For best performance use quality fittings, thick cable and firm
fitting Anderson sockets to ensure your DC cabling losses are kept to a minimum.
DC power systems can operate between 9.6V DC and up to 18V DC or alternatively from 21.3V DC
and up to 31.5V DC.
NOTE: If you would like to run this unit on DC Voltages between 18V and 21.3V you will need to
purchase a step down power module (DC to DC converter). This ca be handy if you want to run the
Benchy Carbon off commonly available 18V Drill Batteries.
