Trailer brake controllers
CURT Echo Mobile Bluetooth Trailer Brake Controller, 7-way, 1 to 2 axles: published ratings and specifications
Plugs in between the truck and trailer connectors with no wiring at all, and is controlled from a phone. It moves between vehicles in seconds, which is the entire point: a rental truck, a borrowed truck or a second vehicle needs no install.
This page carries only what CURT publishes for this part. Where a figure is not published we leave it out rather than estimating it, because a reader comparing two pieces of towing hardware on a table cannot tell a published rating from a guess and should never have to.

What the manufacturer says about it
- PORTABLE, Echo installs between compatible vehicle and trailer 7-way RV blade connectors and easily transfers between vehicles without under-dash wiring. The vehicle 7-way must provide active +12V power, ground and turn-signal circuits; a vehicle brake-output circuit is not required. Echo uses the 7-way +12V connection to power the trailer brakes, and this circuit should be fused at 30 amps. Some vehicles require tow/haul mode or trailer load detection before 7-way power activates.
- SMARTPHONE-READY, Use the OneControl Auto app on iOS 14+ or Android 9+. Enable Bluetooth and location permissions, then pair Echo inside the OneControl Auto app, not through your phone's Bluetooth settings. Keep the app in the foreground for prompt manual-override response and only adjust settings while stationary. OneControl Auto 2.2.0 adds improved larger-font support, fixes an Echo-screen crash on smaller Android devices and includes additional bug fixes.
- ZERO-TOOL INSTALL, When your vehicle's 7-way already provides the required power and ground, Echo installs without under-dash wiring or tools. The safety strap is stored inside the Echo cap and should be installed before use. With the vehicle running or ignition ON and in Park, plug Echo into the vehicle 7-way first, pair through OneControl Auto, then connect the trailer on a level surface. Flashing yellow indicates 5-8 second calibration; solid green indicates Echo is paired with the trailer connected.
- HIGHLY RESPONSIVE, Echo uses a triple-axis accelerometer for proportional trailer braking and supports trailers with 1-2 axles / 2-4 brakes. Adjust maximum output and sensitivity for your trailer and load. If Bluetooth communication is lost, the brake controller continues operating at the most recently programmed settings; app-based control and controller notifications require app communication. Always test trailer lights and braking before driving.
- VERSATILE, Compatible with cruise control, ABS and low-voltage/PWM systems. An existing factory or aftermarket brake controller will not function while Echo is installed. When vehicle hazard lights are active, use the app's Hazard Lights setting to prevent pulsing trailer-brake output. Echo is designed for Bluetooth communication up to 50 ft unobstructed, though actual range can be limited by the phone, vehicle construction and other obstructions.

Every figure here is the manufacturer's own published rating. A blank is a figure the maker does not publish, and we leave it blank rather than estimating it. The rating stamped on the part you actually receive is what governs.
Before you rely on any of these numbers
A published rating is the maximum the maker will stand behind for that part in isolation. The assembled hitch is limited by its lowest rated component, so a receiver, a shank, a ball mount, a ball and a pin each carry their own figure and the smallest of them is your real limit.
And none of them raises anything on your vehicle. Your payload, GVWR, GCWR and axle ratings come off your own door jamb sticker and owner manual, and no part on this page changes a single one of them.
Frequently asked questions
What are the published ratings for the CURT Echo Mobile Bluetooth Trailer Brake Controller, 7-way, 1 to 2 axles?
CURT publishes controller type of Proportional, trailer axles supported of 1 to 2, connector of 7-way pass through, and more in the table above. Every figure on this page comes from the manufacturer's own listing. The rating stamped or labelled on the part you actually receive is the one that governs.
Is the CURT Echo Mobile Bluetooth Trailer Brake Controller, 7-way, 1 to 2 axles rating the same as what my vehicle can handle?
No. A part rating and a vehicle rating are completely separate things. This part will carry what its maker says it will carry, and your vehicle will carry what the sticker in your door jamb says. The lower of the two governs, and on most vehicles it is the vehicle. Work your payload sum before you choose hardware.
What limits an assembled hitch?
Whichever component is lowest rated. The receiver, the shank, the ball mount, the ball and the hitch pin each carry an individual rating, and the assembly is limited by the smallest of them. A class V receiver fitted with a 5,000 lb ball mount is a 5,000 lb hitch, not a 17,000 lb one, and the same logic applies to every part in the chain.
Why are some specification cells blank on the comparison?
Because that manufacturer does not publish that figure. We leave it blank rather than estimating it, inferring it from a similar model, or copying it from a retailer listing that may have invented it. On a site about load ratings, a plausible looking number in a specification table is more dangerous than an honest gap.
Where do these figures come from?
From CURT's own product listing, pulled programmatically rather than retyped, which is how the price and image on this page stay current too. We do not test towing hardware in person and we never claim to. Nothing here is a measurement we took, and everything here is a figure the maker published.

Researched, not professional advice. This page is compiled from published standards, manufacturer towing guides and product specifications, and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are towing convention rather than published standards, and they are labelled that way wherever they appear. Nothing here overrides your own ratings. Work your payload sum before your tow rating, because payload is the limit that actually binds on most half ton trucks and nearly every SUV. Load a conventional trailer to 10 to 15 percent tongue weight and a fifth wheel to 15 to 25 percent pin weight, and never lighter: a tail heavy trailer is what starts sway. Weigh the rig loaded rather than trusting a brochure dry weight. A weight distribution hitch and a set of air bags both restore ride height and control, and neither one raises a single rating. Trailer brakes are required by state law above a threshold that varies by state, and a breakaway battery that has quietly gone flat is the normal condition of most trailers on the road.
