What I Saw Happen at Dubai Security Checkpoint – and Why It Can Save You from Stress and Hassle
At Dubai International Airport, I was standing in line for security when a traveler in front of me was stopped. His power bank was too large, and the agent was adamant: "This is not allowed on board." His expensive power bank was confiscated, and he was allowed to travel without further ado.
That's when I realized: many travelers don't know the exact rules. And honestly, neither did I until that day. Later, I looked into it in detail. These are the official carry-on regulations for power banks in 2025.
Why Are Power Banks So Strictly Regulated?
A power bank contains a lithium-ion battery. This can become dangerous if misused or damaged: overheating, fire hazard, or short circuit. Therefore, aviation regulations apply worldwide.
Powerbank Rules Hand Luggage 2025
1. Always in your hand luggage
-
Power banks are not allowed in the hold (checked baggage).
-
Reason: if a fire breaks out in the cabin, the crew can intervene immediately, but not in the hold.
2. Capacity in Wh (Watt hours) counts
-
Airlines look at capacity in Wh (not just mAh).
-
Calculation rule: mAh ÷ 1000 × Voltage (usually 3.7V) = Wh
Example: 20,000 mAh → 20 × 3.7 = 74 Wh
3. Limits according to IATA guidelines
-
<100 Wh (usually up to ±27,000 mAh) → allowed in unlimited quantities in hand luggage.
-
100–160 Wh (±27,000–43,000 mAh) → permitted, but max. 2 pieces and with airline approval.
-
>160 Wh → prohibited in commercial flights.
4. Maximum number
-
You are allowed to take multiple power banks <100 Wh , as long as they do not become a stack of 10.
-
Practical: take a maximum of 2 with you to avoid discussions.
5. Packaging
-
Use a case or protective cover.
-
Avoid loose cables or damaged batteries → this may lead to failure.
Examples: Which Powerbank Can I Take?
| Capacity (mAh) | Power (Wh) | Can I take it in hand luggage? | Terms and Conditions |
|---|---|---|---|
| 10,000 mAh | 37 Wh | ✓ Always allowed | No limit |
| 20,000 mAh | 74 Wh | ✓ Always allowed | Practically best choice |
| 30,000 mAh | 111 Wh | ✓ Only with airline approval | Max. 2 pieces |
| 40,000 mAh | 148 Wh | ✓ Only with airline approval | Max. 2 pieces |
| 50,000 mAh | 185 Wh | ✗ Forbidden | Do not take |
International Rules: Where Are They Stricter?
Although the basic rules are the same worldwide via IATA, in practice you will notice that some airports and airlines are stricter:
Dubai (DXB)
✓ Known for strict security checks . Power banks are often scanned individually. Capacity over 100 Wh can lead to confiscation without discussion.
Singapore Changi (SIN)
✓ One of the strictest airports. Even minor deviations (damaged housing, cables connected) can lead to refusal.
United States (JFK, LAX, ATL)
✓ The TSA (Transportation Security Administration) follows IATA guidelines but is known for additional checks. Sometimes they explicitly ask you to show the capacity of your power bank.
Europe (AMS, FRA, IST)
Generally in accordance with IATA guidelines. However, strict regulations apply to the number of units and packaging condition (no loose or torn batteries).
Smart Tips for Carefree Travel with Power Banks
1. Choose the right capacity
A power bank of 10,000–20,000 mAh (37–74 Wh) is ideal:
-
Big enough to charge your phone 2–4 times.
-
Small enough to take with you without questions.
2. Always check your airline
Rules are similar worldwide, but some airlines (such as Emirates or Singapore Airlines) explicitly ask for capacity.
3. Do not charge during security or boarding
Some airports are paying extra attention to "in-use" power banks. Unplug your cables and keep things simple.
4. Think of alternatives
Sometimes a small solar charger or two compact power banks are more convenient than one large one.
Frequently Asked Questions (FAQ)
Can I charge my power bank on the plane?
Yes, as long as the airline allows it. Preferably use a USB port in your seat and not the power bank itself during turbulence or takeoff/landing.
How many power banks can I take with me?
Unlimited under 100 Wh, but practically max. 2. Above 100 Wh, a maximum of 2 with permission.
How do I convert mAh to Wh?
Divide mAh by 1000 and multiply by 3.7 (standard voltage). Example: 20,000 mAh = 74 Wh.
Can I take a broken power bank?
✦ No, damaged or bulging batteries will not be accepted. Please recycle them.
Can I put a power bank in my checked suitcase?
✦ No, this is prohibited worldwide due to fire hazard. Always keep it in your carry-on luggage.
Complete Checklist: Power Bank in Hand Luggage
-
✓ Only in hand luggage, never in checked luggage
-
✓ Max. 100 Wh → always allowed
-
✓ 100–160 Wh → only with airline approval (max. 2 pieces)
-
✓ >160 Wh → prohibited
-
✓ Damaged power banks = risk of refusal
-
✓ Keep cables loose, use a case
Ready for Carefree Flights?
A good power bank gives you freedom: no stress about dead batteries during transfers or delays. But make sure you know the rules.
Just like with my complete carry-on travel experience in Turkey, one small detail can make or break your entire trip.
