result: 4.5 volt charger, not 5 volt?

On the 24th of March I posted the following, and many of you had opinions,
so I thought I'd let you know the result of my test:

Yes, the cheap COBY device, set to 4.5 volts, works just fine. The camera's
"charging" light goes on for about 1/2 hour, then goes out. The battery
indicator then shows the battery to have a full charge.

Thanks, all who helped.

I have 3 FujiFilm digital cameras that all use the same type of 5 volt
chargers. One of the chargers is missing, and I want to give my oldest
camera to my daughter. I can only find 4.5 volt universal chargers that
fit
the camera's plug-in. I can set the polarity correctly. Will the slightly
lower voltage damage the camera? Will it be sufficient to recharge the
battery? I hesitate to "just try it" because of the possible damage.


FujiFilm MX-700. Battery is model no. NP-100 - Lithium Ion 3.6v 1350mAh.
And, yes, I plug the charger into any of my 3 cameras to charge their
batteries. I have purchased a COBY universal adapter CA-11, that is one
integrated unit with the polarity and voltage switches on the transformer,
so are less likely to be accidentally changed. One of the 4 rigidly
connected male jacks fits the camera female exactly. So I'll give it a try.
I'll let you all know if smoke is emitted! Thank you for the help.
