Are you one of those travelers who cannot imagine a trip without a power bank? You are not alone! In today’s world, where our smart devices have become an essential part of everyday life, external batteries – also known as power banks – have become indispensable travel companions. But do you know all the rules related to carrying them on airplanes? In this article, we will подробно review the latest guidelines and tips for safely and legally carrying your external batteries when traveling by air.

Latest International Air Transport Association (IATA) requirements for external batteries

According to the latest International Air Transport Association (IATA) Dangerous Goods Regulations (DGR) and Lithium Battery Guidance, external batteries (power banks) are considered spare lithium-ion batteries. They may only be carried in carry-on baggage. This means your power bank must travel with you in the aircraft cabin and not in checked baggage.

Important: if your carry-on baggage is taken at the boarding gate and placed in the cargo hold, the power bank must be removed and carried with you into the cabin.

How many external batteries can you bring?

IATA guidelines do not define a strict quantity limit for batteries under 100 Wh intended for personal use, but they must be for personal use only. Airlines may apply additional restrictions, so it is recommended to check the rules of your airline before traveling.

External battery capacity: why it matters

When choosing an external battery for travel, the most important factor is its capacity, measured in watt-hours (Wh). The battery capacity is usually indicated on the device casing. If only the mAh value is shown, it can be converted into Wh using the following formula:

Wh = (mAh × V) ÷ 1000

Most power banks use a voltage of approximately 3.7 V.

Higher-capacity batteries have stricter restrictions:

1. Up to 100 Wh: Allowed in carry-on baggage without airline approval. These are typically standard travel power banks (e.g., 10,000–20,000 mAh).
2. From 100 Wh to 160 Wh: Allowed only with airline approval. Typically limited to no more than two batteries per passenger.
3. Over 160 Wh: These batteries are not allowed on passenger aircraft and may only be transported as dangerous goods cargo under special regulations.

Tips for safe and smooth travel planning

1. Check battery capacity: Before traveling, make sure you know the watt-hour rating of your battery. This information should be indicated on the battery itself.
2. Contact your airline: If your power bank exceeds 100 Wh, it is recommended to obtain airline approval in advance.
3. Keep in carry-on baggage: External batteries are not allowed in checked baggage.
4. Protect the terminals: Ensure battery terminals are protected against short circuits. Protective cases or original packaging are recommended.
5. Use only undamaged batteries: Damaged or swollen batteries are not permitted on flights.
6. Stay informed: Regularly check the latest IATA and airline rules, as they may change.

External batteries are a great way to ensure your devices never run out of power during a trip. However, it is important to know and follow the rules for carrying them on airplanes. When choosing a battery for travel, consider its capacity and always check your airline’s requirements. By following these guidelines, you can enjoy uninterrupted device usage during your trip without safety or legal concerns.

If you have friends or family members who travel frequently, be sure to share this important information with them. Knowing how to properly transport external batteries can help avoid unpleasant situations at the airport and ensure a smooth journey for everyone.

Safe and pleasant travels with your trusted external battery!
