I finally caved and bought a 3DS a few months ago, and while I love the thing, it’s always bothered me that it shipped with a bulky AC wall adapter, instead of a USB power cord like I’d grown accustomed to with all of my other gadgets. So on a lark, and with a few long flights on the horizon, I Googled around for 3DS USB cables. Lo and behold, they exist! And they work!

If you own a 3DS or 3DS XL and don’t have this cord, it’s the best $4 you’ll spend today. In addition to taking up less space in my bag, the cord lets me power my 3DS anywhere I charge my iPhone, including from an inexpensive external battery pack like this one.

This all means that I don’t have to crank down my brightness to save power, or suffer through minor panic attacks during long car or plane rides without an AC outlet. In fact, if I lost the 3DS’s original power brick, I’d have zero motivation to buy a new one. [Amazon]
