Power Supply Bench Testing Question
I hope this is the right section. I am trying to bench test a aftermarket radio and I was going to use this cheapo jump starter I have for power. I hooked my multimeter up to the jump starter and got a reading of about 13v. I know I am supposed to connect both the red and yellow to the positive (+) and the black to the negative (-) and it should start. However, at 13v, is it safe to hook the radio up or should I wait until it goes down below 12v? It being a cheapo jump starter it doesn't hold a charge that well.
