AdHitch Necessities

AdHitch External Battery System


     The AdHitch Portable Display System can easily be attached to any vehicle with a 2 inch hitch receiver. The next step is giving the sign power.

     While running off the main battery of the vehicle is possible, it requires the vehicle be turned on in order to give power to the sign. This may or may not be the best option for your use. 

     We have developed an external battery system that is easy to install, cost-effective and efficient. This system allows you to give power to the AdHitch when the vehicle is off. The other main benefit is that your secondary battery recharges whenever the vehicle is turned on. 

Everything you need to get started!
