String winder question
Years ago, I bought a battery-powered (rechargeable li-ion) string winder. Like a small, cordless drill gizmo. Says "STP," like the motor oil treatment company, on it, I guess it was some kind of promo deal. But I didn't get it free! Maybe it was made by Ernie Ball? I see now those babies are over $40, yikes!
I can't find the power supply cord to recharge it. All I see on the winder is "4v" and nothing else. I am pretty ignorant on electrical issues, how can I tell what rating power supply I need? I have a bunch of power supply cords around here! I hope I can find the original but so far, nada. Of course, the end fitting is key to even insert it to charge it.
