If I had to pick the one item I see most often at the X-ray machine, it would be the power bank. Almost every international passenger carries one, and the mistake is nearly always the same: it ends up in the wrong bag. Electronics look harmless, but they contain lithium batteries, and airlines treat them very strictly. Here are the electronics and power bank rules for international flights, explained in simple words.
Khulasa (Urdu Summary): Power bank aur spare lithium batteries sirf cabin bag mein rakhein, checked baggage mein bilkul nahi. 100Wh (takreeban 27,000mAh) tak bina ijazat ke allowed hai, aur 100 se 160Wh tak airline ki manzoori chahiye. Laptop aur tablet screening par alag tray mein nikalein.
Reference: ICAO & IATA lithium battery guidance. Your airline may apply stricter limits.
Quick Answer: Power Bank Rules for International Flights
Power banks and spare lithium batteries must travel in your cabin (carry-on) bag only, never in checked baggage. A power bank up to 100 Wh (about 27,000 mAh) is normally allowed without special permission. Between 100 Wh and 160 Wh you need your airline's approval, and usually only two such batteries are allowed. Anything above 160 Wh is not allowed on passenger flights.
1. Why Power Banks Must Stay in the Cabin
A lithium battery can overheat or catch fire if it is damaged or short-circuited. In the cabin, the crew can see and handle the problem quickly. In the cargo hold, nobody can reach it. That is the reason for the rule, and it applies to every airline.
2. Power Bank Capacity Limits (mAh and Wh)
Airlines count battery size in watt-hours (Wh), while most power banks show mAh on the label. You can convert easily:
Wh = (mAh ÷ 1000) × 3.7 volts
| Power Bank Size | Approx. Watt-Hours | Rule |
|---|---|---|
| 10,000 mAh | 37 Wh | Allowed in cabin bag |
| 20,000 mAh | 74 Wh | Allowed in cabin bag |
| 26,800 mAh | about 99 Wh | Allowed in cabin bag |
| 30,000 mAh | 111 Wh | Needs airline approval |
| 40,000 mAh | 148 Wh | Needs airline approval |
| Above about 43,000 mAh | Over 160 Wh | Not allowed |
If the label already shows Wh, use that number. If you cannot read the label at all, do not carry that power bank, because an officer cannot confirm its size.
3. How to Carry Power Banks Safely
- Keep them in the cabin bag, in a pocket that is easy to reach at screening
- Protect the connectors: use the original box, a small pouch, or cover the ports with tape
- Do not carry a damaged, swollen or overheating power bank
- Do not carry loose battery cells without protection
- Carry only the number you really need. Several airlines limit how many you can bring
- Check your airline's rule on using a power bank during the flight, because some airlines now restrict charging from a power bank onboard
4. Laptops, Tablets and Phones
- Keep all of them in the cabin bag, since they carry lithium batteries and valuable data
- At the security check, take laptops and tablets out of the bag and place them in a separate tray. See our airport security check guide
- If a device must go in checked baggage, switch it off completely (not sleep mode), and protect it from being pressed or switched on
- Phones and earbuds can stay in your pocket or bag until an officer asks you to place them in the tray
5. Cameras, Drones and Other Gadgets
- Spare camera batteries must travel in the cabin bag, with the terminals covered
- Drone batteries also travel in the cabin bag
- Many countries, including some Umrah destinations, restrict or need permission for drones, so check before you carry one
- Electric shavers and trimmers with built-in batteries are usually fine in the cabin. Keep them switched off
6. Smart Luggage and E-Cigarettes
- Smart suitcases with a built-in battery are accepted only if the battery can be removed, so you can take it into the cabin. Check with your airline before you buy or travel
- E-cigarettes and vapes must be in the cabin bag, and they cannot be used onboard. Check the laws of your destination country as well
7. Chargers, Cables and Adapters for Umrah Travelers
Chargers and cables are safe in either bag, but your power bank is not. For Saudi Arabia, many hotels use Type G sockets, and some also use Type C or F, so a universal travel adapter is a good idea. Keep it in the cabin bag together with a short charging cable.
8. If Your Cabin Bag Is Gate-Checked
Sometimes the overhead bins are full and the airline asks to take your cabin bag to the hold at the boarding gate. Before you hand it over, take out your power bank, spare batteries, laptop and other lithium devices and keep them with you.
9. What Happens If a Power Bank Is in Your Checked Baggage
Checked bags are also screened by X-ray. Batteries show up clearly on the image, so a bag can be pulled aside for a manual check. You may be asked to open it, take the power bank out and move it to your cabin bag, and that can delay your check-in. It is much easier to pack correctly the first time.
From My Duty Desk: What I Notice Most
- Power banks placed in the suitcase at the last minute, right before the bag is closed
- Power banks with no readable label, so the capacity cannot be checked
- Laptops left inside the cabin bag, which makes the X-ray image unclear
- A tangle of cables and chargers that hides other items and slows down the check

Frequently Asked Questions
Can I put a power bank in my checked baggage?
No. Power banks and spare lithium batteries must go in the cabin bag only.
How many mAh is allowed in a power bank on international flights?
Up to about 27,000 mAh (100 Wh) is normally allowed without approval. Larger ones up to 160 Wh need approval from your airline.
How many power banks can I carry?
For power banks under 100 Wh, airlines usually allow a reasonable number for personal use, but some set their own limit. For 100 to 160 Wh, usually two. Always check your airline's rule.
Can I carry a laptop in checked baggage?
It is allowed if the laptop is fully switched off and protected, but it is safer to carry it in the cabin bag, since it is valuable and can be damaged in the hold.
Do I have to take my laptop out at the security check?
Yes. Laptops and tablets are normally placed in a separate tray so the X-ray image is clear.
Can I use my power bank during the flight?
It depends on the airline. Several airlines now restrict or ban charging from a power bank onboard, so ask before you fly.
Airline rules can change, so always confirm with your airline before you travel. To avoid other surprises at the counter, also read our prohibited items list and the Umrah packing checklist. Safe travels!
