About Check N Tow
Where Innovation Meets Practicality
Welcome to Check N Tow — a brand born from real-world experience and a simple goal: make trailer-light testing fast, reliable, and frustration-free.
As someone who works hands-on with trailers and electrical systems, I saw the same problem time and time again — testing trailer lights required hooking up to a tow vehicle, wasting time and creating safety headaches. I knew there had to be a smarter way.
So, I built one.
How It Started
What began as a garage project quickly grew into a solution trusted by haulers, mechanics, and RV owners nationwide. Every Check N Tow unit is designed, 3D-printed, and hand-assembled right here in the U.S., using high-quality components and rigorous testing to ensure reliability with every use.
Because when it comes to towing, safety and dependability shouldn’t be optional.
Built for Real-World Use
The Check N Tow tester is compact, durable, and built for on-the-go performance. Each unit features:
-
Compatibility with 18V–48V batteries
-
Interchangeable battery adapters for major tool brands like Milwaukee and DeWalt
-
A 12V cigarette-style port for powering accessories
-
Three resettable circuit breakers that protect your gear and keep you working
Whether you’re in an RV park, managing a fleet, or prepping for the weekend tow, Check N Tow lets you test and troubleshoot trailer lights anywhere, anytime — without needing a tow vehicle.
