The Nintendo Switch is officially the fastest-selling video game console in US history. After the colossal flop that was the Wii U, Nintendo came back with a vengeance last year and released a novel new video game system that people absolutely adore. Portability is one of the console’s best features, but battery life isn’t quite as good as some people had hoped. That’s where the Antank Switch Battery Charger Case comes in. It packs a nice big 6,500 mAh battery that doubles your Switch’s battery life, and we definitely recommend picking one up.
