Hi, I've been looking for days for a charger of a hair trimmer Babyliss E709E but unfortunately I couldn't find one with the exact voltage (5.6v), thus I bought an adjustable AC/DC charger with multi voltages that can go for 1.5/3/4.5/6/7.5/9/12V.
So my question, which voltage is it safer to use on a 5.6v battery, 4.5v or 6v?
These are some images of what I have:
