Product Description


USB power supply cord for the 9530 Brake Monitor

Use this cord to plug your 9530 Brake Monitor into a USB power supply.
Traditionally, most RVs included a 12-volt socket on the dash. But newer RVs usually have USB power supply ports. This cord replaces the 12-volt power cord that came with your Brake Monitor and plug in this USB cord instead.

The 9533 can be used on many accessories that utilize a DC jack with a 4 mm barrel.


Power Supply: USB port
DC Jack Size: 4 mm barrel with a 1.7 mm internal hole
