Here’s the bad news: The Nintendo Switch can only run for about three hours on a charge while playing Zelda. The good news? Nintendo opted to use USB-C for charging, meaning you can use a battery pack to keep it alive during a long flight.
Jackery’s Titan S includes two standard USB ports (one with Quick Charge 2.0), plus a USB-C port that you’ll use both for input and output. Depending on the game you’re playing, it might not actually charge the Switch so much as dramatically slow down its discharge rate, but either way, the result is longer battery life. So hook up a C-to-C cable, recline your seat, and enjoy the trip sans-battery anxiety.
