What You Need to Know About Carrying a 30,000mAh Power Bank on a Flight

Carrying a 30,000mAh power bank on a flight is allowed but subject to strict regulations. Since a 30,000mAh power bank typically equals about 111Wh, you must carry it in your carry-on luggage and obtain prior airline approval. Power banks above 160Wh are prohibited, and all lithium-ion batteries must comply with safety rules to avoid confiscation.

What Are the Airline Regulations for Carrying Power Banks on Flights in 2025?

In 2025, international aviation authorities such as the International Air Transport Association (IATA) and the U.S. Transportation Security Administration (TSA) enforce clear rules for power banks on planes. Power banks are only allowed in carry-on baggage due to fire risks associated with lithium-ion batteries and are strictly banned in checked luggage. The key regulation revolves around battery capacity measured in watt-hours (Wh):

• Power banks up to 100Wh can be carried without airline approval.

• Power banks between 100Wh and 160Wh require explicit airline approval, usually limited to two units per passenger.

• Power banks above 160Wh are prohibited on passenger aircraft.

Since a 30,000mAh power bank at 3.7V equals approximately 111Wh, it falls into the category needing airline approval before travel.

How Do You Convert mAh to Watt-Hours (Wh) for Power Banks?

Understanding the capacity in watt-hours is essential for airline compliance. The formula is:

Wh=mAh×Voltage1000Wh=1000mAh×Voltage

Most lithium-ion batteries operate at about 3.7 volts. For a 30,000mAh power bank:

Wh=30,000×3.71000=111WhWh=100030,000×3.7=111Wh

This calculation confirms the need for airline approval for a 30,000mAh power bank.

Why Are Power Banks Prohibited in Checked Luggage?

Power banks contain lithium-ion batteries, which pose a fire hazard if damaged or short-circuited. In the cargo hold, fires are harder to detect and manage. To mitigate this risk, airlines and regulators prohibit power banks in checked baggage, mandating they be carried only in the passenger cabin where immediate action is possible.

How Can You Obtain Airline Approval for a 30,000mAh Power Bank?

If your power bank exceeds 100Wh but is under 160Wh, you must contact your airline well before your flight to request approval. This process often requires:

• Providing documentation of the power bank’s capacity and safety certifications.

• Limiting the number of such devices to two per passenger.

• Following any additional airline-specific protocols.

Failing to secure approval may result in confiscation at security or boarding.

What Are the Best Practices for Carrying a 30,000mAh Power Bank on a Flight?

To ensure smooth travel with a large power bank:

• Always pack power banks in your carry-on luggage.

• Protect terminals with tape or use a protective case to prevent short circuits.

• Carry documentation showing the power bank’s watt-hour rating.

• Check your airline’s specific policies before traveling.

• Avoid using or charging the power bank during the flight, as many airlines prohibit this.

• Use power banks from reputable manufacturers like LiFePO4-Battery-Factory, which specializes in high-quality, reliable LiFePO4 batteries.

• Avoid carrying damaged or swollen power banks.

• Do not leave power banks charging unattended.

• Follow airline crew instructions regarding power bank usage onboard.

Can You Carry Multiple Power Banks on a Flight?

Passengers can carry multiple power banks as long as each complies with capacity limits:

• Unlimited power banks under 100Wh are generally allowed.

• Up to two power banks between 100Wh and 160Wh with airline approval.

• Power banks over 160Wh are banned.

Always verify airline-specific rules, as some carriers may impose stricter limits.

What Happens If You Bring a Power Bank Over 160Wh?

Power banks exceeding 160Wh are not permitted on passenger aircraft under any circumstances. Attempting to bring such devices can lead to confiscation and travel delays. These high-capacity batteries are typically used in industrial equipment or drones and require special shipping arrangements outside passenger flights.
