What to look for

  • Power banks: USB-C Power Delivery at 45 W minimum, ideally 65 W, so the handheld charges while you play.
  • Docks: HDMI 2.0 for 4K60 TV output, USB ports for controllers, Ethernet for steady online play, and 100 W pass-through charging.
  • Capacity: 20,000 mAh+ roughly doubles a handheld's play time; stay under 100 Wh for flights.
