Traveling with electronics is now a standard part of modern life, and with those devices comes the inevitable need for portable phone chargers on a plane. But can you bring a battery pack on a plane? The answer isn’t always straightforward.

Regulations surrounding battery packs can be confusing, varying based on the type of battery, its size, and the airline you’re flying with. This comprehensive guide will break down everything you need to know to ensure your travels are smooth and compliant with all safety regulations.

Why Are There Restrictions on Battery Packs?

Before diving into the specifics, it’s crucial to understand why airlines and aviation authorities have implemented these restrictions. The primary concern is safety. Lithium-ion batteries, commonly found in battery packs, can pose a fire risk due to:

• Overheating: Batteries can overheat if they are damaged, short-circuited, or improperly manufactured.
• Thermal Runaway: In extreme cases, overheating can lead to a thermal runaway, a chain reaction that causes the battery to rapidly increase in temperature, potentially leading to fire or explosion.
• Cargo Fires: Fires in the cargo hold can be particularly dangerous because they are difficult to detect and extinguish quickly.

To mitigate these risks, aviation authorities like the Transportation Security Administration (TSA) in the United States and the International Air Transport Association (IATA) have established regulations for transporting batteries on aircraft.

General Guidelines for Battery Packs on Planes

The rules for carrying battery packs depend on several factors, but here’s a general overview:

• Type of Battery: Lithium-ion and lithium metal batteries are the most common types of batteries found in portable chargers. Regulations differ slightly between the two.
• Watt-hour (Wh) Rating: For lithium-ion batteries, the Wh rating determines whether the battery is allowed, and if so, under what conditions.
• Lithium Content: For lithium metal batteries, the lithium content (in grams) is the key factor.
• Carry-on vs. Checked Baggage: Generally, spare lithium batteries are only allowed in carry-on baggage.

Lithium-Ion Batteries: The Watt-Hour (Wh) Rating

Lithium-ion batteries are commonly used in smartphones, laptops, tablets, and, of course, battery packs. The key metric for these batteries is the watt-hour (Wh) rating, which indicates the amount of energy the battery can store. The TSA and IATA have specific guidelines based on this rating:

• Up to 100 Wh: These batteries are generally allowed in carry-on baggage without quantity limits (for personal use). Examples include batteries for smartphones, standard laptops, and many power banks.
• 101-160 Wh: These batteries require airline approval and are limited to a maximum of two per passenger. This category includes extended-life laptop batteries and larger power banks.
• Over 160 Wh: These batteries are generally prohibited from both carry-on and checked baggage due to safety concerns.

How to Find the Watt-Hour (Wh) Rating

The Wh rating is usually printed on the battery itself or on the device containing the battery. It can also be found in the product specifications or the user manual. If the Wh rating isn’t directly available, you can calculate it using the battery’s voltage (V) and amp-hour (Ah) rating:

Wh = V x Ah

If the battery is rated in milliamp-hours (mAh), convert it to amp-hours by dividing by 1000:

Ah = mAh / 1000

For example, a battery rated at 3.7V and 5000mAh would have a Wh rating of:

Ah = 5000 mAh / 1000 = 5 Ah

Wh = 3.7 V x 5 Ah = 18.5 Wh

This battery would fall well within the allowed range for carry-on baggage.

Table: Lithium-Ion Battery Regulations

Watt-Hour (Wh) Rating	Allowed in Carry-on	Allowed in Checked Baggage	Airline Approval Required	Quantity Limits
Up to 100 Wh	Yes	No	No	No Limit (for personal use)
101-160 Wh	Yes	No	Yes	Maximum of 2 per passenger
Over 160 Wh	No	No	No	Prohibited

Lithium Metal Batteries: The Lithium Content

Lithium metal batteries are typically non-rechargeable and are often found in devices like watches, calculators, and some cameras. The regulations for these batteries are based on their lithium content, measured in grams:

• Up to 2 grams of lithium: These batteries are generally allowed in carry-on baggage. They can also be installed in a device in checked baggage.
• Over 2 grams of lithium: These batteries are typically prohibited from both carry-on and checked baggage unless specifically approved by the airline.
