The International Air Transport Association (IATA) guidelines suggest that power banks with capacities of 100Wh to 160Wh may be carried on a plane, subject to airline approval. For power banks over 160Wh, special permission is usually required. Since 40,000mAh equates to approximately 148Wh (based on a typical 3.7V), you can bring a 40,000mAh power bank on a plane, but it's critical to check with your specific airline as policies may vary.

FAQs & Answers

  1. What is the maximum mAh capacity allowed for power banks on planes? Most airlines allow power banks up to 100Wh (approximately 27000mAh at 3.7V) without special approval, while those between 100Wh and 160Wh require airline approval.
  2. How do I convert mAh to Wh for power banks? To convert mAh to Wh, multiply the battery voltage by the mAh and divide by 1000. For example, 40000mAh at 3.7V equals about 148Wh.
  3. Do all airlines have the same rules for carrying power banks? No, airline policies can vary. It's important to check with your specific airline before traveling with high-capacity power banks.
