Doubling Up on Power: Navigating Airline Rules for Carrying Two Power Banks

Staying powered up on the go is essential for many travelers. Power banks are a lifesaver for keeping our devices charged, but navigating airline regulations surrounding these portable powerhouses can be confusing. Can you carry two power banks on a flight? The answer, like most things related to air travel, is: it depends.

The key factor lies in the battery’s Watt-hour (Wh) rating, which indicates its energy capacity. Most power banks fall under 100Wh, and for these smaller power banks, the good news is you can generally carry two in your carry-on baggage. Airlines typically permit a reasonable number of these smaller power banks for personal use, understanding their necessity for modern travelers. However, it’s always prudent to check with your specific airline, especially if you’re carrying an unusually large number.

The rules change significantly when dealing with larger power banks. For batteries with a Wh rating between 101 and 160, a limit of two spare batteries is usually imposed, and critically, these require prior airline authorization. Contacting your airline well in advance of your travel date is crucial to ensure they approve your specific power banks. Simply packing them and hoping for the best at the airport is risky and could lead to them being confiscated.

Here’s a breakdown to simplify things:

• Small Power Banks (Under 100Wh): Generally, two are allowed in carry-on baggage. Check with your airline for specifics, especially if carrying more than two. These should never be packed in checked luggage.

• Larger Power Banks (101-160Wh): Maximum two spares allowed in carry-on baggage, but only with prior airline approval. Prohibited in checked luggage.

• Power Banks Over 160Wh: Generally prohibited both in carry-on and checked luggage.

Remember, Watt-hour (Wh) ratings are different from milliampere-hour (mAh) ratings. To calculate Wh, use the following formula: (mAh * Voltage) / 1000 = Wh. This information is usually printed on the power bank itself.

Beyond the number of power banks, safe handling is paramount. Protect the terminals from short-circuiting by covering them with tape or storing them in separate cases. Damaged or recalled power banks are strictly prohibited.

By understanding these guidelines and checking with your specific airline, you can ensure a smooth journey with your essential power banks, keeping your devices charged and ready for anything.
