Travel Regulations: What You Need to Know

When flying with a power bank, it’s important to follow airline regulations to avoid security issues or confiscation.


TSA and International Guidelines

  • Carry-on Only: Power banks must be packed in carry-on luggage; they are not allowed in checked bags due to fire risks.

  • Capacity Limits: The maximum capacity allowed is 100Wh (Watt-hours) per power bank without airline approval. Some airlines may allow up to 160Wh with prior permission.

  • Multiple Power Banks: Most airlines allow two or more power banks within safe capacity limits, but it's best to check with your airline.
