This advanced electric trailer brake controller delivers reliable, proportional braking performance for a wide range of towing needs, from recreational vehicles and boat trailers to heavy-duty cargo hauling, ensuring safety for drivers who frequently transport loads across varying terrains. Featuring intuitive proportional sensor technology, it automatically adjusts braking force based on your vehicle's deceleration, providing smooth, controlled stops whether navigating steep hills, busy highways, or sudden emergency situations. Users benefit from an easy-adjust knob for setting power output, a boost function that adds up to three levels of extra braking strength for heavier loads, and a manual override for unexpected stops, all while monitoring real-time data like voltage delivery through a clear LED display. Designed with versatility in mind, it supports electric or electric-over-hydraulic brake systems, mounts conveniently on or under the dash with self-leveling capability within a 90-degree vertical range—no post-installation tweaking needed—and includes multiple mounting options, such as brackets and pockets, along with a quick-disconnect feature for simple storage when not in use. Continuous diagnostics check for proper connections and potential issues like shorted magnets, while reverse operation remains proportional yet customizable, and battery-saving modes minimize drain. Ideal for trailers with 1 to 4 axles, this complete kit includes all necessary hardware and is backed by a two-year warranty for peace of mind on every journey.
