Best charging spots
These are the most reliable places to charge at John Glenn Columbus International Airport:
- Power tower kiosks in the Concourse B gate area — CMH's busiest concourse has the most charging infrastructure
- Gate seating with built-in outlets across Concourses A, B, and C
- Escape Lounge (Concourse B, near gate B32) — power outlets at every seat for lounge guests
Dedicated charging stations
Blue-lit "power tower" kiosks stand in the gate seating areas of each concourse; additional outlet strips are at food-court seating throughout the terminal.
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 airport's official amenities page confirms USB and standard outlets at gate power towers but doesn't specify USB-C — bring a USB-A cable or your own USB-C wall adapter as backup since some older gate seating may only have standard AC outlets and USB-A ports.
