I want to use my Warm & Safe heated jacket off the bike to keep warm while stargazing near my home. Just wanted to ask whether anyone has successfully powered their heated gear directly from a battery tender. The daisy chain would be AC power outlet—extension cord—Battery Tender—24’ SAE to SAE cord—SAE to Coax Female adapter—Heat Controller Unit—Heated Jacket. This path eliminates the battery which is typically how power gets to heated gear while riding. Will this setup fry the controller, the jacket, or me?
