Power Bank Bans Are Spreading on Airlines
What You Need to Know Before You Fly
Can I Still Bring a Power Bank on a Plane in 2025?
Yes, but the rules are getting stricter by the day.
In 2025, more airlines began banning in-flight use of power banks and tightening how they must be carried. Southwest, Singapore Airlines, and all major Korean carriers have already rolled out new restrictions.
If you fly with a power bank, especially internationally, you need to follow these updated rules or risk being stopped at the gate.
What Are the New Airline Battery Restrictions?
Global rules you must follow:
Carry-on only: Never place a power bank in checked luggage.
Capacity limits: Up to 100 Wh: allowed without approval
100–160 Wh: allowed with airline approval (limit of two)
Over 160 Wh: prohibited
Clear labeling: Wh (watt-hour) capacity must be printed directly on the device
Powered off: Use and charging may be banned during flight
Placement matters: Most airlines require it to be stored under your seat, not overhead
These rules originate from the FAA, ICAO, and IATA and are enforced by nearly all major commercial airlines.
Why Are Airlines Banning Power Banks?
Because most still use lithium-ion batteries, which contain flammable liquid electrolytes.
When these batteries are damaged, overcharged, or overheated, they can go into thermal runaway, a chain reaction that causes the cell to smoke, swell, catch fire, or explode.
How Do I Make Sure My Power Bank Is Allowed?
Before you fly, double-check these essentials:
- It’s under 100 Wh, or you’ve received airline approval
- The Wh rating is printed clearly on the battery
- It’s carried in your hand luggage, never checked
- You don’t plan to use or charge it mid-flight (unless specifically allowed)
- It shows a trusted safety certification: UL, CE, or 3C (China)
Rules vary by airline and they’re changing fast.
Some carriers now ban in-flight charging altogether. Others require power banks to be stored under the seat or submitted for pre-approval.
Always check your airline’s most up-to-date battery policy before you pack.
Why Solid-State Batteries Are the Future of Travel
Traditional lithium batteries use flammable liquid. Solid-state replaces it with a stable solid—reducing fire risk at the source.
In tests shared with global regulators, solid-state cells stayed stable even when heated to 250°C—far beyond failure points for lithium-ion.
No rule changes yet, but regulators are actively reviewing solid-state tech. Safer chemistries are in focus—and likely to shape future travel rules.
Introducing SolidSafe™
Power That Meets the Moment
SolidSafe™ is one of the world’s first solid-state power banks designed for travelers.
- Cuts down the flammable liquid inside
- Built to align with the strictest airline policies
- Designed around the same solid-state chemistry now being evaluated by regulators
- Delivers dependable power with a dramatically lower fire risk
It’s more than a better battery. It’s a smarter way to stay charged, especially when the rules are changing fast.
Final Take: Don’t Risk Lithium. Go Solid.
Airlines are cracking down—and they’re not bluffing.
If your power bank isn’t flight-ready, it can be flagged, confiscated, or even keep you off the plane.
SolidSafe™ gives you more than power, it gives you peace of mind.
It’s engineered with the same solid-state chemistry regulators are actively evaluating, and it’s built to align with today’s travel requirements and where battery safety is clearly headed.
Fly smarter. Fly safer. Go solid.
