Nobody will deny the 3DS's biggest downfall is it's abysmal battery life. I think it surprised everybody because Nintendo's portables have always been about reliable battery, usually at the cost of newer tech and better performance.
As always, Nyko is here to offer a solution. They provided a Wii remote charger almost before anyone realized it was an issue, and now my Nyko Wii charge base is an essential part of my setup and still kicking five years on. Now Nyko has the Power Pack+, a heavy duty 3DS battery that adds a quarter-inch to the handheld's width but more than doubles its battery life. Check out the unboxing below...I have a feeling this will be another piece of indispensable equipment.
