Can you take a power bank on a plane? UAE rules explained
Short answer
Yes — but carry-on only, never checked baggage. Power banks up to 100Wh (roughly 27,000mAh) fly without approval on UAE carriers; 100–160Wh needs airline approval; over 160Wh is banned. A standard 20,000mAh power bank (74Wh) is comfortably within the limit.
Why the rule exists (and why it's strict)
Power banks are lithium batteries, and a damaged lithium cell can enter thermal runaway. In the cabin, crew can handle it; in the cargo hold, nobody can — which is why every airline worldwide bans them from checked luggage, and why security will pull a checked bag off the belt to remove one. Pack it in your hand luggage, ideally where you can reach it.
Doing the Wh maths
Airline limits are in watt-hours (Wh), power banks are sold in mAh. The formula: Wh = (mAh × 3.7V) ÷ 1000. So 10,000mAh = 37Wh, 20,000mAh = 74Wh, 27,000mAh ≈ 100Wh — the no-approval ceiling. Reputable power banks print the Wh figure on the casing; unlabelled units are the ones security confiscates, regardless of size.
UAE airline rules at a glance
- Emirates, Etihad, flydubai, Air Arabia — all follow IATA rules: carry-on only, ≤100Wh free, 100–160Wh with airline approval (usually max two units), >160Wh prohibited.
- Usage on board — policies on charging devices from a power bank mid-flight have tightened; several carriers now restrict in-flight use, so check your airline's current policy and always keep the unit visible, not buried.
- Damaged or swollen units — don't fly with them, full stop. A swollen battery is a battery asking to be retired.

Frequently asked questions
Is a 20,000mAh power bank allowed on Emirates and Etihad?
Yes — 20,000mAh equals 74Wh, well under the 100Wh no-approval limit. Carry it in your hand luggage only.
What happens if I leave a power bank in checked baggage?
Baggage screening flags it, your bag gets pulled and searched, and the power bank is removed — sometimes making you and your bag miss the flight. It is never worth it.
How many power banks can I bring?
Under 100Wh, most carriers allow several for personal use (commonly up to 15–20 under IATA guidance, though airlines can set lower limits). In the 100–160Wh band, the cap is typically two, with approval.
