If you travel with tech, you know this feeling: your phone’s at 2%, you’re halfway through a layover, and every outlet is either taken—or not working. That’s where a power bank steps in. But here’s the question we hear all the time: Can I bring a power bank on a plane? Short answer: Yes—but not just any power bank, and not in just any bag.
Whether you’re off-grid or heading overseas, this guide breaks down how to fly with portable power—without getting held up at security.
Airline Regulations: What You’re Allowed to Bring
When it comes to flying with a power bank, it’s not about brand—it’s about battery chemistry and watt-hours. Most airlines follow the guidelines set by the International Air Transport Association (IATA) and the International Civil Aviation Organization (ICAO).
Here’s what matters:
- Power banks must be carried in your carry-on—never checked.
- Most airlines allow power banks up to 100Wh (roughly 27,000mAh) without prior approval.
- Some may allow between 100Wh and 160Wh, but you’ll need airline consent.
- Anything above 160Wh is a no-go.
Our Poseidon Pro and Poseidon Nano, you're well within these limits.
Carry-On Is the Only Way
To put it plainly: do not pack power banks in your checked luggage. Lithium-ion batteries can pose fire risks in cargo holds, which is why airlines are strict about this. Keep your power bank in your carry-on, and make sure it’s:
- Turned off or in a standby mode
- Protected from accidental activation (a solid case helps)
- Easily accessible in case security asks to inspect it
Our power banks are built with internal safety tech to prevent overcharging, short circuits, and other in-flight issues.
Travel Tips: Keeping Power in Your Hands
Before you take off, run through this checklist to avoid any power—or TSA—surprises:
- Know your airline’s rules. Some have stricter limits, especially international carriers.
- Charge up before you fly. A full power bank keeps your gear alive through delays and layovers.
- Bring the right cables. A power bank’s no good if you can’t connect it to your gear.
For International Flights: Know Before You Go
Heading overseas? Each country has its own take on lithium battery rules, so double-check both the airline and the destination. You’ll also want the right travel adapters—especially if you’ll be recharging your power bank abroad. If you don’t already have one check out our International Travel Adapter
