I have the original 3DS and I use the charging dock to charge it pretty much exclusively. But lately I've been seeing some oddness going on with it. Sometimes the orange light that shows that the 3DS is charging will flicker a lot. I can then adjust the cord connecting into the dock to get the flickering to stop. I'm also noticing that the cord itself feels rather loose when plugged into the dock, and a little loose when plugged into the system itself, but not as much. I don't remember if it's always been loose like that or not, or know if a little looseness is normal or not.
I haven't noticed any decrease in performance or battery life, but I'm worried that the charger may be sending irregular amounts of electricity into my 3DS and damaging it. Is this something I should be worried about? And can I send the charger and dock to Nintendo for repair or replacement? Any suggestions would be wonderful to hear.
