Playing the Nintendo Switch in portable mode is incredibly convenient, but the short battery life can leave users wanting. Today, Anker announced two new battery packs that are optimized for fast charging the Nintendo Switch. One is a $70, 13400mAh pack that provides up to 10 hours of additional play time. The other allows for 15 additional hours of play time with a 20100mAh battery, retailing for $90. Both devices look quite sleek, like all of Anker's products, and are branded with the Nintendo Switch logo.
