Portable battery air travel rules have undergone significant changes in 2025, impacting travelers worldwide.
The European Union Aviation Safety Agency (EASA) and U.S. aviation authorities have updated their safety protocols concerning the transport of lithium-ion batteries, most commonly found in power banks and other rechargeable electronic devices. The goal is simple: prevent fire hazards mid-flight.
Understanding the New Regulations
The latest EASA regulation prohibits travelers from placing portable batteries—also called power banks—in checked luggage. Instead, they must be packed in carry-on bags only. This shift addresses serious concerns about the risks of lithium batteries overheating, short-circuiting, or catching fire when stowed in the cargo hold, where a fire may not be detected or extinguished quickly.
According to the agency, “if a battery is swollen, excessively hot, or producing smoke, these are clear signs that something is wrong.” While such issues can be safely managed in the aircraft cabin, they pose a much higher risk if they occur out of sight in checked baggage.
Why Are Lithium Batteries Dangerous?
These batteries are found in almost all modern electronic devices—mobile phones, tablets, laptops, cameras, e-cigarettes, and even smart luggage. The risk lies in their chemistry. If damaged or poorly manufactured, lithium batteries can combust spontaneously, sometimes with explosive force. Temperature changes, impact, or manufacturing defects can all lead to dangerous malfunctions.
What the Rules Now Say
The EASA has issued strict guidelines for carrying electronic devices and spare batteries onboard:
- Power banks must be in hand luggage, not checked bags.
- Only two spare batteries per person are allowed.
- Each battery must be individually protected to avoid short circuits (e.g., covering terminals or storing in original packaging).
- Recharging batteries during the flight is prohibited.
- Power banks up to 100 Wh are permitted in most cases. Between 100–160 Wh may be allowed with prior airline approval.
Smart Luggage and Other Devices Affected
The rules don’t just apply to power banks. Other battery-powered gear is also subject to the updated safety regulations. That includes:
- Digital cameras and extra camera batteries
- Drones and spare drone batteries
- Vape pens and e-cigarettes
- Smart luggage with non-removable batteries
For smart suitcases, the battery must be removable. Batteries must not exceed 2.7 Wh or 0.3 grams of lithium content. If the battery cannot be removed, the bag may be refused at check-in.
Battery Condition Matters
Even if your batteries are packed correctly, they must be in good working condition. EASA advises travelers to avoid using damaged, swollen, or non-certified lithium batteries. Always check for visible damage before flying, and purchase only from trusted brands and retailers. A defective battery may not just get confiscated—it could endanger your entire flight.
Enforcement and Penalties
This isn’t just a recommendation—it’s a rule. Airports and airlines across the EU and U.S. are increasing enforcement, and security personnel may scan checked baggage for prohibited items. If a battery is found inside your checked luggage, you may be called to open your suitcase, face delays, and in some cases, even be fined or have the item confiscated.
Some airlines are proactively warning passengers and updating their online policies to reflect the changes. If you’re planning to fly soon, it’s a good idea to double-check your airline’s specific battery guidelines before heading to the airport.
Summary Table: Battery Air Travel Guidelines
| Device/Battery Type | Allowed in Checked Luggage? | Allowed in Carry-On? | Special Conditions |
|---|---|---|---|
| Power Banks | No | Yes | Max 100 Wh (160 Wh with airline approval) |
| Spare Lithium Batteries | No | Yes | Max 2 per person, terminals must be protected |
| Laptop/Tablet/Phone (with battery installed) | Yes | Yes | Must be turned off in checked luggage |
| Smart Luggage | Only if battery removable | Yes | Battery must be under 2.7 Wh |
| E-cigarettes/Vapes | No | Yes | Use and charging onboard prohibited |
Final Tips for Travelers
- Pack your power banks and spare batteries in your carry-on bag.
- Check battery capacity and condition before travel.
- Use original packaging or terminal covers to protect batteries.
- Review your airline’s battery policy ahead of time.
- Don’t recharge your power bank or vape onboard.
The bottom line? Lithium batteries have become essential for modern travelers—but with that convenience comes responsibility. Stay informed, pack smart, and fly safe.
