Alright, so. I bought a refurbished Gold Nintendo 3DS XL directly from the Nintendo website a little less than a year ago. Recently, I've been having some problems when I try to charge it. When I plug it in, it doesn't easily start charging. It usually takes a little wiggling of my charger to get the orange light to turn on. To test out whether it was my charger or my 3DS, I tested out my sister's charger with my 3DS and it had the same results. I then decided to see if the chargers work smoothly on my sister's 3DS (she bought it basically on it's launch date), and they both charge her 3DS just fine.
I'm just wondering if this is simply the port on my 3DS or the chargers themselves, as they are fairly old chargers. My 3DS does hold a charge and will last for a few hours on a full charge, but charging it is the problem. I don't want to have to continue to wiggle around the port with the charger just to get it to charge because I feel like I'm damaging my 3DS everytime I do it. Help?
