I have 3 FujiFilm digital cameras that all use the same type of 5 volt\nchargers. One of the chargers is missing, and I want to give my oldest\ncamera to my daughter. I can only find 4.5 volt universal chargers that fit\nthe camera's plug-in. I can set the polarity correctly. Will the slightly\nlower voltage damage the camera? Will it be sufficient to recharge the\nbattery? I hesitate to "just try it" because of the possible damage. Is\nthere a better place for me to post this query?
