Best charging spots
These are the most reliable places to charge at Seattle–Tacoma International Airport:
- North Satellite Charging Lounge near gates N1–N12 — largest dedicated charging area at SEA
- Concourse C, gates C17–C25 — USB-C bars along full window-facing seating
- Satellite Terminal S-gates — USB-C at nearly every seat after the 2022 refresh
Dedicated charging stations
A large dedicated charging lounge is in the North Satellite (N Concourse) near gates N1–N12; dedicated charging bars run the full length of seating near gates C17–C25 and throughout the S-gates Satellite.
Bring your own charging cable — dedicated kiosk stations at US airports provide the power outlet but not the cable. USB-A, USB-C, and standard 120 V outlets are the most common configurations.
Pro Tip
The underground connector train to the Satellite Terminal maintains WiFi and you arrive at a terminal with excellent charging at the S-gates — don't rush to charge before the train; charge at the gate instead.
