When I click the "authorized dealers" button above, it just says" click here for details" & when I do, it comes back to original screen?

This charger says it is 110-220 volts and 50/60 cycle. Does that mean it can plug into a 220 plug directly (with the right adapter of course)? I have a 220-110 converter but can I plug this in to a wall with only the appropriate adapter (American 2 prong to whatever country's two or 3 prong wall adapter for instance without the converter)

I have 3 battery and in all cases the charger take more the 5 hours to complete the charge, and in some cases the yellow light, become weak,(almost turned off) whats happening ?
someone have some ideia ? my power source is 127v 60hz

Hi, I asked the previous question, a think my charger is broken, or I bought a fake one, because when I plug on power without the battery, the LED is always off, when a put the battery the LED is always on, for almost 6 hours, 3 times more than indicated, then the LED turn off, no blinking, no change color, nothing,
Im worried because I dont want damage my baterrys.
I will continue charge via camera.
any ideia ? thanks of answer in so short notice.
