Can I Carry a 20000mAh Power Bank on EasyJet Domestic Flights?
Updated 2026-08-01 · Power Bank Guide
When you ask, “Can I carry a 20000mAh power bank on EasyJet domestic flights?” the answer is yes—under the right conditions. The 20000mAh power bank EasyJet policy hinges on the 100‑watt‑hour (Wh) rule that applies to all U.S. and European airlines, including EasyJet. Below you’ll find the numbers, the math, and a practical recommendation for a power bank that meets the policy.
Understanding the 100‑Wh Rule and the Math for 20000mAh
The International Air Transport Association (IATA) and the Federal Aviation Administration (FAA) set a 100‑Wh cap on lithium‑ion batteries for carry‑on luggage. To convert milliampere‑hours (mAh) to watt‑hours, use:
Wh = (mAh ÷ 1000) × 3.7V
For a 20000mAh pack:
Wh = (20000 ÷ 1000) × 3.7 ≈ 74 Wh
74 Wh is comfortably below the 100 Wh threshold, so a 20000mAh pack is allowed on EasyJet flights as long as it’s in carry‑on luggage and the battery is not damaged or defective.
Carry‑On Only: No Checked Luggage for Power Banks
All major airlines, including EasyJet, forbid placing lithium‑ion batteries in checked bags. The battery’s high energy density makes it a fire risk if exposed to temperature extremes or pressure changes during the check‑in process. Keep the power bank in your cabin, preferably in a clear, padded pouch or a dedicated power‑bank sleeve. This also ensures you can reach it quickly for charging during the flight.
How Many Charges Can You Expect?
Real‑world efficiency for USB‑C PD power banks ranges from 60–70%. The INIU 20000mAh Portable Charger, rated at 22.5 W, delivers a practical output of about 18 W to a phone. Here’s a quick look at typical devices:
- iPhone 17 (approx. 10 Wh battery): 4–5 full charges
- Samsung Galaxy S23 (approx. 11 Wh battery): 4–5 full charges
- Google Pixel 8 (approx. 10.5 Wh battery): 4–5 full charges
- Xiaomi Mi 13 (approx. 12 Wh battery): 4–5 full charges
These numbers assume the phone’s battery is near empty and the charger is fully functional. If you’re traveling with multiple devices, plan accordingly.
EasyJet’s Specific Policy (2024)
EasyJet states that:
- Power banks with a capacity up to 100 Wh are permitted.
- They must be carried in cabin luggage only.
- Passengers should be ready to remove the battery if requested by cabin crew.
Because regulations can shift, double‑check the EasyJet help page or call customer service before you fly.
Comparing Other Airlines for Reference
- Delta, United, American (U.S.): 100 Wh limit, carry‑on only.
- British Airways, Lufthansa, Air France (EU): Same 100 Wh rule, carry‑on only.
- Qatar Airways, Emirates: 100 Wh limit, but allow larger batteries in special cases if you notify in advance.
In every case, the 20000mAh (74 Wh) power bank is well within limits, provided it’s in your carry‑on.
