What Changed in 2026?
Airline and authority rules that took effect in 2026. Older and regional updates are in our articles section.
You can still bring your power bank on board, but using it or charging devices during the flight is now banned on Lufthansa, Swiss, and Austrian — except for medical devices.
DGCA directions reported in early 2026: no charging phones or power banks from aircraft outlets during flight; keep spare batteries in hand baggage and out of overhead bins as your airline directs.
Dangerous goods rules for the 2025–2026 edition updated via the official addendum; pair the IATA passenger lithium PDF with your airline notice for trip-level compliance.
JAL announced MLIT-aligned limits: two power banks per passenger, 160 Wh or less each, and no in-flight charging from power banks — confirm wording on the official notice.
From 15 January 2026: two power banks per passenger, cabin baggage only (no overhead bins on Edelweiss), switched off for the whole flight — medical exceptions per airline policy.

Can You Bring a Power Bank on a Plane?
Yes, you can bring most power banks on a plane -- but there are a few rules you need to know. The most important one: your power bank must go in your carry-on bag. It is never allowed in checked luggage. This rule applies everywhere in the world, on every airline, no exceptions.
Whether your specific power bank is allowed depends on how much energy it stores, measured in Watt-hours (Wh). Our free tool above does the math for you.
What Size Power Bank Is Allowed?
Airlines group power banks into three categories based on their energy.
- Small and medium (under 100 Wh): Allowed on all airlines. No special permission needed. This includes most power banks up to about 27,000 mAh. IATA
- Large (100 to 160 Wh): Allowed, but you need to ask your airline first. Maximum 2 units. Contact your airline at least 48 hours before your flight. FAA
- Extra-large (over 160 Wh): Not allowed on passenger flights. No exceptions, even with permission. TSA
How Do I Know How Many Watt-Hours My Power Bank Has?
Most power banks show their size in mAh -- the big number like 10000 or 20000 on the back. Here is the simple formula:
Wh = (mAh × 3.7) ÷ 1,000
3.7 is the standard voltage for most power bank batteries.
Use our calculator at the top of this page -- enter your mAh number and we will convert it instantly.
Quick Reference: Common Power Bank Sizes
| Size | Wh | Verdict |
|---|---|---|
| 5,000 mAh | 18.5 Wh | Always allowed |
| 10,000 mAh | 37 Wh | Always allowed |
| 20,000 mAh | 74 Wh | Always allowed |
| 26,800 mAh | 99.2 Wh | Allowed (just under the limit) |
| 27,000 mAh | 99.9 Wh | Very close to the limit, check with your airline |
| 30,000 mAh | 111 Wh | You'll need airline permission |
| 50,000 mAh | 185 Wh | Not allowed on passenger flights |

Why Can't I Put It in My Suitcase?
It comes down to safety. If a battery catches fire in the cargo hold (where checked bags go), no one can get to it. But in the cabin, the crew can respond immediately. That's why every aviation authority in the world says: power banks in carry-on only.
If security finds a power bank in your checked bag, they'll remove it and your bag could be delayed. At some airports (especially in China and India), they may pull your entire bag off the flight.
Do Different Airlines Have Different Rules?
Yes. While the basic rules (under 100 Wh = OK, over 160 Wh = no) are the same everywhere, airlines can add their own restrictions on top:

Tips for Traveling With a Power Bank
- Always carry it on — never put it in checked luggage.
- Cover the ports — use a case or tape over the USB ports to prevent accidental short circuits.
- Check for damage — if it's swollen, cracked, or feels unusually hot, don't take it on a plane.
- Keep the label readable — airport security may refuse power banks without visible capacity markings.
- Keep it within reach — don't bury it at the bottom of your bag. Crew may need to see it.
- Unplug during turbulence — if you're charging a device, disconnect it when things get bumpy.
Common Questions
Is a 20,000 mAh power bank allowed on flights?
Yes. A 20,000 mAh power bank equals about 74 Wh, which is well under the 100 Wh limit. It's allowed on virtually every airline. Just put it in your carry-on.
What about a 27,000 mAh power bank?
That's about 99.9 Wh — technically under the limit, but extremely close. Most airlines will allow it, but since it's borderline, we'd recommend checking with your airline beforehand just to be safe.
Can I use my power bank during the flight?
It depends on your airline. Many Asian and European carriers now ban in-flight use. North American airlines generally still allow it but want you to keep the power bank visible. Use our tool above and select your airline to check.
What if my power bank is over 160 Wh?
It's not allowed on any passenger flight, anywhere in the world. There are no exceptions, even with airline approval. If you need that much portable power, consider getting a smaller power bank for travel or contact your airline's cargo department about shipping it separately.
