I have a Canon SX210 IS which has not a connector to use a external power supply. So I wanted to connect "my" power source to the pins the battery usually touches.
In the back of my camera, it says 4.2 V but the battery has 3.7 (model NB-L5).
Right now, I have in my hands a voltage regulator (7805) and a diode which would drop 0.7 V. I plan to connect the 7805 to a car battery so there is no line noise. Do you know if it safe to feed my camera with those 4.3 V?
Should I use less voltage? Would the camera be damaged if I pass 4.2 V?
I haven't tried anything yet just for precaution.
Thanks in advance!
Does somebody know about a voltage regultor with arround (3.8 - 4.3)V of output?
