PowerCore Speed 20000 PD Review

Most power banks are currently designed for smartphone charging which is much slower than what the Switch is capable of, and won't provide a net positive charge while the Switch is on. The Anker PowerCore Speed outputs the full 30W of power that the Switch is capable of, meaning it will power the Switch at the same speed as a wall outlet.

At 20000 mAh it is the maximum capacity that's allowed to be taken on a plane, and enough to charge the Switch 4 times, which depending on the game will add over 12 to 22 hours of extra play time.
