Most travellers now fly with several battery-powered items: a phone, laptop, tablet, camera, headphones, smartwatch, portable charger or vape. But packing considered one of them within the unsuitable bag could cause real problems on the airport.
In 2026, aviation safety authorities are warning travellers to pay closer attention to lithium batteries after reports that thousands and thousands of batteries are still being packed incorrectly. The biggest mistake is straightforward: power banks, portable chargers and spare lithium batteries mustn’t go in checked luggage.
They belong in your carry-on bag or personal item, where they may be reached quickly in the event that they overheat, smoke or catch fire. This matters much more when your carry-on gets taken away on the gate and sent underneath the plane.
2026 Airline Battery Rules at a Glance
| Item | Checked luggage | Carry-on / personal item | What to know |
|---|---|---|---|
| Power banks | No | Yes | Must stay within the cabin |
| Portable chargers | No | Yes | Treated as spare lithium batteries |
| Spare camera batteries | No | Yes | Protect terminals from short circuit |
| Spare drone batteries | No | Yes | Check airline quantity and watt-hour limits |
| Vapes / e-cigarettes | No | Yes | Do not use or charge onboard |
| Phone charging cases | No | Yes | Treated like external battery packs |
| Laptops | Rules vary | Best selection | Must be powered off if checked |
| Phones | Rules vary | Best selection | Keep with you each time possible |
| Tablets | Rules vary | Best selection | Keep protected and powered off if checked |
| Smart luggage batteries | Remove before checking | Yes | Bag could also be refused if battery will not be removable |
The safest habit is straightforward: power banks, spare batteries and removable batteries stick with you. Valuable electronics are often higher within the cabin too.
Why Are Power Banks Not Allowed in Checked Luggage?
Power banks aren’t allowed in checked luggage because they contain lithium batteries that may overheat if damaged, poorly packed, overcharged, exposed to heat or affected by a defect.
In rare cases, lithium batteries can enter thermal runaway. That means the battery heats faster than it may cool itself down. It may swell, smoke, burn or ignite.
If that happens within the cabin, passengers and crew can spot the issue quickly. Cabin crews are trained to reply to battery incidents. If the battery is hidden inside a suitcase within the cargo hold, it is way harder to access.
That is why this rule will not be just airport red tape. A small charger within the unsuitable bag can change into a serious safety issue.
What Batteries Should Never Go in Checked Luggage?
Before you check a suitcase, search for anything with a loose, spare or removable lithium battery.
These items should stay in your carry-on or personal item:
- Power banks
- Portable phone chargers
- Spare lithium batteries
- Spare camera batteries
- Spare drone batteries
- Spare laptop batteries
- Rechargeable battery packs
- Phone battery charging cases
- Removable smart-luggage batteries
- Vapes and e-cigarettes, where legally permitted
You also needs to consider carefully before checking precious electronics with installed batteries, including:
- Phones
- Laptops
- Tablets
- Cameras
- Headphones
- E-readers
- Smartwatches
- Handheld gaming devices
Some airlines may allow certain devices with batteries installed in checked luggage in the event that they are completely powered off and protected against damage. But for many travellers, the smarter selection is to maintain electronics within the cabin.
Checked bags get dropped, delayed, searched and sometimes sent on their very own little vacation. Your laptop doesn’t need that character-building experience.
Spare Batteries vs. Batteries Installed in Devices
This is where the principles confuse a variety of travellers.
A spare battery is any battery that will not be installed contained in the device it powers. An influence bank also counts since it is an external battery used to charge other devices.
A battery installed in a tool is different. This includes the battery built into your phone, laptop, tablet, camera, headphones or smartwatch.
| Battery type | Examples | Best place to pack it |
|---|---|---|
| Spare battery | Loose camera battery, drone battery, spare laptop battery | Carry-on only |
| Power bank | Portable charger, phone charging case | Carry-on only |
| Installed battery | Phone, laptop, tablet, camera | Carry-on preferred |
| Removable battery | Smart-luggage battery, some camera grips | Remove before checking |
The easiest rule to recollect is that this:
If the battery is loose, removable or used to charge something else, don’t check it. The FAA’s lithium battery guidance says power banks and spare lithium batteries must travel in carry-on baggage, not checked luggage.
What Happens If Your Carry-On Gets Checked on the Gate?
Gate-checking is considered one of the simplest ways to unintentionally break the battery rule.
You may pack your power bank appropriately in your carry-on at home. Then you reach the gate, the overhead bins are full and the agent tags your carry-on to go underneath the plane.
At that moment, your carry-on has change into checked luggage.
Before handing it over, remove:
- Power banks
- Portable chargers
- Spare batteries
- Vapes or e-cigarettes, where legally permitted
- Medication
- Travel documents
- Valuables
- Anything you can not afford to lose
The easiest system is to maintain all power banks and spare batteries in a single small pouch inside your personal item. If your roller bag gets gate-checked, you’ll be able to remove the pouch in seconds as an alternative of digging through your suitcase while the boarding line gives you the collective death stare.
What Is the 100 Wh Rule for Power Banks?
Airlines measure lithium-ion battery size in watt-hours, written as Wh.
Most standard phone power banks are under 100 Wh and are often allowed in carry-on baggage. Larger batteries may require airline approval, and really large batteries are generally not allowed in normal passenger baggage.
| Battery rating | What it often means |
|---|---|
| Under 100 Wh | Usually allowed in carry-on baggage |
| 101–160 Wh | Airline approval could also be required |
| Over 160 Wh | Generally not allowed in normal passenger baggage |
The 100 Wh rule matters most for giant laptop power banks, skilled camera gear, video equipment and drone batteries.
A typical 10,000 mAh power bank is commonly around 37 Wh. A 20,000 mAh power bank is commonly around 74 Wh. Larger power banks can get near the limit, so check before you pack.
According to CATSA’s battery packing guidelines, travellers should keep batteries and electronic devices containing batteries of their carry-on baggage, avoid damaged or recalled batteries, and protect spare batteries from short-circuiting.
How to Find the Watt-Hours on a Power Bank
Look for the Wh rating printed on the back, bottom or side of the facility bank. Newer batteries often show this number clearly.
If the label only shows mAh and volts, you’ll be able to calculate watt-hours with this formula:
Volts x amp-hours = watt-hours
Since 1,000 mAh equals 1 Ah, a 20,000 mAh power bank is 20 Ah.
For example:
3.7 volts x 20 Ah = 74 Wh
That would often fall under the 100 Wh carry-on limit.
If the label has rubbed off and the airline cannot confirm the battery rating, the item could also be refused. Do not depend on guessing on the airport.
Can Laptops, Phones and Tablets Go in Checked Luggage?
Laptops, phones and tablets have batteries installed contained in the device, in order that they aren’t treated the identical way as loose spare batteries or power banks.
However, airline rules vary. If an airline allows these devices in checked luggage, they must be completely powered off, protected against damage and packed in order that they cannot unintentionally activate.
That means fully powered off, not sleeping, hibernating or sitting there quietly planning to get up mid-flight.
In practice, keep phones, laptops and tablets within the cabin each time possible. They are precious, easy to break and sometimes essential in case your checked bag is delayed.
Are Vapes Allowed in Checked Luggage?
No. Vapes and e-cigarettes mustn’t be packed in checked luggage because they contain batteries. They should travel within the cabin and must not be used or charged in the course of the flight.
Rules for vaping products also vary by destination, and a few countries restrict or ban them. If an adult is legally travelling with one, it still must follow airline battery rules.
If you’re packing for another person, check for these before closing a checked suitcase. A vape tossed into checked luggage can create the identical battery issue as other lithium-powered devices.
Can You Check Smart Luggage?
Smart luggage can often be checked provided that the battery may be removed.
A sensible bag is luggage with built-in charging, tracking or other battery-powered features. If the bag goes into the cabin and meets carry-on size limits, it might be accepted as a carry-on. If it must be checked, the battery must often be removed and brought into the cabin.
If the battery can’t be removed, the airline may refuse to just accept the bag as checked luggage.
Before travelling with smart luggage, find the battery compartment at home. Do not wait until the check-in counter to find that the “removable” battery requires a tiny screwdriver, a prayer and the patience of a saint.
Can You Pack Drones and Camera Batteries in Checked Luggage?
The drone or camera body could also be allowed in checked luggage by some airlines, but spare lithium batteries must be removed and carried within the cabin.
Spare camera batteries and drone batteries must be individually protected so the terminals cannot touch metal or one another. Use the unique packaging, a battery case, a protective pouch or tape over exposed terminals.
If you travel with several batteries for photography or video work, check your airline’s quantity limits before you fly. Battery rules may be stricter for skilled video gear and bigger drone batteries.
How to Pack Batteries Safely for a Flight
Loose batteries should never be thrown right into a bag with coins, keys, jewellery, cables or other metal objects. Battery terminals can short-circuit in the event that they touch metal.
Pack batteries safely by:
- Keeping them in the unique packaging when possible
- Covering exposed terminals with tape
- Using a battery case or sleeve
- Keeping each battery separate
- Storing them in a protective pouch
- Keeping them away from sharp or heavy items
- Packing them somewhere easy to access
This is particularly necessary for camera batteries, drone batteries and loose rechargeable cells.
Do Not Fly With Damaged or Recalled Batteries
Do not travel with a battery that’s swollen, cracked, leaking, unusually hot, damaged or recalled.
A swollen power bank will not be “probably wonderful.” It is a damaged battery and must be taken to an appropriate recycling or disposal location.
Before flying with an older power bank, check the model number and search for current recall notices from the manufacturer or your government recall site. Some recalled power banks could also be prohibited onboard entirely.
If a battery looks questionable, leave it at home. Replacing a charger is cheaper than coping with a security incident on the airport.
What to Do If a Battery Overheats on the Plane
If a battery or device becomes hot, starts swelling, smokes, sparks or smells strange during a flight, tell the cabin crew immediately.
Do not put it within the overhead bin. Do not hide it in a bag. Do not take it to the washroom. Cabin crew are trained to reply to battery incidents, but they should know instantly.
The goal will not be to handle the issue yourself. The goal is to alert the people trained to take care of it.
Two-Minute Battery Check Before Every Flight
Before leaving for the airport, do that quick check:
- Find every power bank, spare battery and battery-powered device.
- Check each battery for swelling, cracks, heat or damage.
- Look for the Wh rating.
- Check for recalls if the battery is older or unfamiliar.
- Put power banks and spare batteries in your carry-on or personal item.
- Protect loose battery terminals.
- Check the principles for the airline operating your flight.
- Remove batteries before gate-checking a carry-on bag.
This takes lower than two minutes and may prevent a pulled bag, confiscated item or airport delay.
Before You Check Your Bag: Battery Packing Checklist
Before you check a suitcase or hand over a carry-on on the gate, make sure that:
- Power banks are in your carry-on
- Portable chargers are in your carry-on
- Spare batteries are in your carry-on
- Vapes or e-cigarettes are in your carry-on, where legally permitted
- Battery terminals are protected
- Watt-hours are checked
- Damaged batteries are removed
- Recalled batteries are left at home
- Smart-luggage batteries may be removed
- Your battery pouch is simple to grab before gate-checking
Final Advice
Before you check any bag, open it and search for batteries.
Power banks, portable chargers, spare batteries and removable lithium batteries stick with you within the cabin. Phones, laptops, tablets and cameras are often safer in your carry-on. If your carry-on gets taken on the gate, remove your battery pouch before the bag goes underneath the plane.
The goal will not be to stop travelling with electronics. The goal is to stop packing them on autopilot.
A two-minute battery check before every flight can save your bag, your gear and possibly your travel day.
