Overview
12V DC Self-Regulating Heating Cable for RV, Camper & Off-Grid Pipe Freeze Protection
YeloDeer 12V RV Self-Regulating Heating Cable is a low-voltage external pipe heating cable designed for RVs, campers, trailers, boats, off-grid plumbing, outdoor water lines, small hoses, and battery-powered freeze protection applications.
Unlike standard 120V pipe heat tape, this cable runs on 12V DC power. It is ideal for mobile and remote setups where standard household power may not be available, such as RV water lines, camper plumbing, boat pipes, solar battery systems, emergency water systems, and outdoor low-voltage installations.
The cable uses self-regulating heating technology, which automatically adjusts heat output based on surrounding temperature. It produces more heat in colder areas and reduces output as the pipe or cable warms up. This helps provide safer, more energy-conscious freeze protection for 12V systems.

Important Before You Order
This product requires 12V DC power. It is not a 120V plug-in pipe heat cable. Do not connect it directly to a household 120V AC outlet.
Before purchasing, please confirm:
• Your power source is 12V DC
• Your power supply or battery can handle the required current
• You can install proper fuse protection
• Your wire gauge is suitable for the cable length and current
• The heating cable will be installed externally on the pipe
• The cut end will be sealed correctly if the cable is shortened
• The electrical connections can be protected from moisture
This Product Is for External Pipe Use Only
This cable should be installed on the outside of the pipe, hose, or water line.
Do not insert it inside drinking water pipes, sewer pipes, drain lines, tanks, or any pipe where the cable will be in direct contact with water inside the pipe.
For internal pipe applications, choose a dedicated in-pipe or in-water heating cable.
Self-Regulating Does Not Mean Auto-Off
Self-regulating means the cable changes heat output as temperature changes.
When the pipe is colder, the cable produces more heat.
When the pipe becomes warmer, the cable reduces heat output.
However, self-regulating does not mean the cable fully shuts off by itself.
If the cable is connected to 12V DC power, it may continue to draw power. For battery-powered systems, use a thermostat, switch, fuse, or power management method if you want better control and battery protection.
