10 Best Trailer Brake Controllers 2025 in the United States

The Tekonsha 90160 Primus IQ Electronic Brake Control is a solid choice for those in need of a reliable trailer brake controller. One of its key strengths is the Plug-N-Play feature, which allows for easy installation with compatible T-connectors. This is a significant benefit for users who may not be very experienced with wiring or installation, as it helps simplify the process. The digital LED readout adds another layer of convenience, providing real-time diagnostics and making it easier to monitor performance.

This brake controller boasts good performance with its proportional braking feature that works in reverse, enhancing safety while reversing a trailer. The Boost feature is also a plus, allowing for adjustable braking power for different situations and improving control, especially for heavier loads.

However, there are some drawbacks to consider. The T-connector required for installation is sold separately, which could be an additional expense and a slight inconvenience for users who might expect a complete package. Additionally, while the self-diagnostics feature is useful, it may not cover all potential issues, leaving some users uncertain about specific problems. The dimensions and weight of the device make it compact and lightweight, which is great for minimizing extra bulk in your vehicle. The Tekonsha 90160 Primus IQ is well-suited for casual to moderate trailer users who value ease of use and reliability. Its strong performance and user-friendly features make it a commendable choice, though users should be prepared for the additional purchase of installation accessories.

The REESE Towpower 8507111 Brakeman IV Digital Brake Control is a compact and efficient choice for those needing a reliable brake controller for trailers. One of its standout features is its digital display, which allows for easy monitoring and adjustment of output settings. This can be particularly useful for users who want precise control over braking, enhancing safety while towing. The unit supports up to eight braking systems, making it a versatile option for various trailer setups. Its small design is another advantage, allowing for flexible installation in different orientations without the need for leveling, which can simplify the setup process for users who may not be very tech-savvy. Additionally, the advanced internal circuit protection helps prevent damage from overloads or short circuits, providing peace of mind during use.

There are a few considerations to keep in mind. While the compact design is beneficial, some users might prefer a larger interface for easier readability, especially during night driving or in less-than-ideal lighting conditions. Furthermore, the installation process, while generally straightforward, might still pose some challenges for those unfamiliar with brake controller setups.

In terms of compatibility, it’s essential that users verify whether this model suits their specific towing needs, as not all trailers may benefit equally from its features. For those looking for a reliable and straightforward brake controller that doesn’t take up much space but still performs well, the Brakeman IV is a solid option. It particularly caters well to occasional users or those with standard towing requirements. More experienced users or those with larger, more complex setups might find themselves wanting additional features or more robust control options.

The Tekonsha 8508220 Brake-EVN Proportional Electric Trailer Brake Controller is designed for trailers with 1 to 4 axles, making it a great option for a range of users, from occasional travelers to more frequent haulers. One of its key strengths is the proportional braking system, which adjusts the brake power based on how hard you apply your tow vehicle's brakes. This feature enhances safety by providing automatic and smoother braking in various situations. The inclusion of an internal inertia sensor is a notable plus, ensuring that the braking response is aligned with your needs.

Installation is made easy with the Plug & Play port and removable electrical connector—this means that users can set it up without extensive technical knowledge. Additionally, the easy-to-read LED display provides real-time diagnostics and alerts, which can be especially helpful for monitoring the system while driving. The manual control lever is another useful feature, allowing for direct application of the brakes when necessary.

While it boasts compatibility with a wide range of vehicle brands, the vehicle-specific wiring harness required for installation is sold separately, which could incur additional costs and complicate the setup process slightly. Some users may also find the display information to be minimal in terms of detailed diagnostics.
