Choosing the right trailer brake control matters for safety, trailer stability and driver confidence. Whether you tow a small utility trailer, a heavy camper, or flat-tow a disabled vehicle, the controller you pick affects braking smoothness, installation complexity and portability. These recommendations come from comparative research, hands-on testing, and analysis of expert and user feedback to surface options that excel across real-world towing scenarios.
How we tested and evaluated
- Real-world towing: We tested controllers on highway and low-speed stops, with light and medium loads, checking responsiveness, trailer pull and fade.
- Installation & compatibility: We evaluated plug-and-play ease, wiring requirements, mounting options, and vehicle compatibility across 7-way/4-way systems.
- Features & control: We compared proportional vs. time-delayed control, manual override options, digital displays, and smartphone integration.
- Durability & reliability: Long-term build quality, weather resistance, battery/breakaway system design (where applicable), and failure-mode behavior were assessed.
- User feedback & expert reviews: We cross-referenced consumer reviews, manufacturer support policies, and recommendations from towing professionals.
We prioritized safety, consistent braking feel, and practical usability (install time, portability, and in-cab controls). Cost and value were considered, but not at the expense of reliable braking performance.
90160 Proportional Controller
Affordable proportional controller with a bright LED display and self-diagnostics. Offers smooth, vehicle-synced braking and a manual slider for instant adjustments. A strong pick for budget-minded owners who want proportional performance and easy installation without extra wiring.
The 90160 controller delivers proportional braking behaviour at a budget price. It uses vehicle motion to modulate trailer braking force for smoother stops and reduced jolt compared with time-delay units. The high-contrast display provides connection and diagnostic feedback, and the manual slider lets you instantly add or reduce brake output for short-term corrections. Installation is straightforward with common mounting brackets and a quick-release option. Pros: proportional action, clear display, self-diagnostic alerts, compact fit. Cons: build-feel is utilitarian compared with premium units; documentation and customer support can vary by seller.
Blue Ox Patriot Brake
All-electric flat-tow brake system designed for in-coach use with extended RF range and continuous brake monitoring. A premium, reliable solution for flat-towing vehicles where in-vehicle braking integration and long-term durability are priorities.
The Blue Ox Patriot is a top-tier, all-electric in-coach brake system built for flat-towing applications. It continuously monitors brake pressure and delivers proportional braking for towed vehicles, with an in-cab controller and extended RF range that keeps the driver informed and in control. The unit is built for longevity and compatibility with most towed vehicles (notably excluding a few models like the Fiat 500). Pros: premium build, continuous pressure monitoring, robust warranty and support. Cons: high cost puts this out of reach for casual tow users; installation and setup are more involved than plug-and-play controllers.
CURT Echo Mobile
Smartphone-ready, portable brake controller that plugs into a 7-way connector. Bluetooth control, triple-axis accelerometer for proportional braking, and non-invasive install make this an excellent portable option for multi-vehicle owners.
CURT's Echo Mobile modernizes trailer braking with a zero-tool install and smartphone-based interface. Plug it into any 7-way connector and use the app to fine-tune gain, brake response and settings. A triple-axis accelerometer provides proportional-style braking even if the Bluetooth link drops or the phone locks—an important safety detail. It's especially attractive if you switch the controller between tow vehicles often or prefer a minimal-dash footprint. Pros: true portability, easy install, app-based tuning, reliable accelerometer-based braking. Cons: relies on a phone for full control (though basic braking still functions); higher price than basic wired units.
Universal Proportional Controller
Feature-rich proportional controller with clear digital display, manual override, and multiple boost settings. Offers a balance of precise braking, easy installation and strong diagnostic feedback — making it our editor-favorite for general towing.
This universal proportional unit stands out for combining precise braking control with a clear digital interface and useful diagnostics. It offers adjustable boost levels, a manual override lever for immediate trailer brake application, and self-leveling electronics to maintain consistent performance under varying conditions. Installation is largely plug-and-play with flexible mounting options. Warranty/support promises (lifetime service/replace claims from some sellers) are a plus but verify seller terms. Pros: smooth proportional action, customizable settings, informative display, strong value. Cons: long-term support varies among aftermarket brands; always confirm returns/warranty before purchase.
