It's frustrating to run out of battery when you're about to level up with your Nintendo Switch. Though there are a lot of external battery options, many of them require you to leave the console turned off in order to charge it properly, so you can't keep playing right away.

But Anker's new battery packs are specially optimized for playing and charging a Nintendo Switch at the same time, said Anker in a release on Thursday. They're the first portable battery packs that are officially licensed for the Nintendo Switch.
