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 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.

The TEKONSHA PRODIGY P3 Electronic Trailer Brake Control is highly regarded in the trailer-brake-controller category. One of its key strengths is its reputation for best value and performance within its class, supported by 15 years of being a premier solution provider. This brake controller is particularly well-suited for those seeking a reliable and high-performing device for their trailer braking needs.

It supports multiple axles, making it versatile for various trailer types and sizes. The unit is known for its user-friendly interface, featuring a clear display and intuitive controls that simplify the adjustment process. The complimentary white glove service is a nice touch for users who may need additional assistance with installation or troubleshooting.

However, some potential drawbacks include its weight of only 0.01 ounces which might raise questions about its durability and build quality. Additionally, the product dimensions (11 x 5 x 3 inches) may be bulkier compared to some modern, compact alternatives. Despite these minor issues, its ranking as #12 in Trailer Brake Controls on Amazon and the same-day shipping option on request make it a compelling choice for users prioritizing performance and ease of use. It is also worth noting that the product has been available since 2015, which indicates a proven track record but might suggest it lacks some of the latest technological advancements seen in newer models.
