Lithium-ion batteries: Allowed in carry-on, not checked luggage
When travelling with an Anker battery bank, it's important to ensure it meets airline regulations. Most airlines allow passengers to bring power banks in their carry-on luggage, but not in checked baggage, due to the risk of fire caused by lithium-ion batteries. The International Air Transport Association (IATA) states that power banks with a capacity of up to 100 watt-hours (Wh) are permitted in carry-on baggage. This is equivalent to around 27,000 milliampere-hours (mAh) or 27,027mAh.
To check if your battery pack complies with regulations, you need to convert mAh to Wh. Most power banks use lithium-ion batteries with a typical voltage of 3.7V. So, for example, a power bank with a capacity of 10,000 mAh would be approximately 37Wh, which is within the allowed range for carry-on luggage. Similarly, a 20,000 mAh portable charger would be approximately 74 Wh, which is also permitted.
It is worth noting that some countries and airlines may have different regulations. For instance, China has banned all power banks manufactured before 2024 on domestic flights. Therefore, it is always a good idea to check the specific airline's regulations and the guidelines from aviation authorities like the FAA or IATA before travelling to ensure that your portable charger is allowed on the plane.
In summary, when travelling with a power bank, keep it in your carry-on luggage and ensure it complies with the relevant airline and country regulations regarding lithium-ion batteries and power bank capacity.

Airline regulations: Vary, so check before flying
Airline regulations regarding power banks vary, so it's important to check the specific rules of your airline before flying. Most airlines permit power banks in carry-on baggage but prohibit them in checked luggage due to the risk of fire associated with lithium-ion batteries. The International Air Transport Association (IATA) states that power banks with a capacity of up to 100 watt-hours (Wh) are allowed in carry-on baggage. However, the capacity limit may differ between airlines, with some allowing up to 160Wh with prior approval.
To determine whether your power bank complies with airline regulations, you may need to convert its capacity from milliamp-hours (mAh) to watt-hours (Wh). For example, a power bank with a capacity of 10,000mAh and a voltage of 3.7V would have an approximate capacity of 37Wh, which is within the allowed range. On the other hand, a 50,000mAh power bank would exceed the 100Wh limit and would typically not be permitted on flights.
It's worth noting that some countries may have specific restrictions on power banks. For instance, China has banned all power banks manufactured before 2024 on domestic flights. Therefore, it's crucial to familiarize yourself with the regulations of your destination country and airline before embarking on your journey.

Capacity: Typically, 100Wh or 27,000mAh is the limit
When it comes to bringing a power bank on a plane, capacity is a crucial factor in complying with airline regulations. Most commercial airlines allow power banks with a capacity of up to 100 watt-hours (Wh) or approximately 27,000 milliampere-hours (mAh) in carry-on baggage. This limit is set by aviation authorities like the Federal Aviation Administration (FAA) and the International Air Transport Association (IATA), ensuring standardized rules for international travel.
It's important to note that the capacity limit may vary slightly between different airlines and countries, so checking the specific regulations of your airline is essential. Some airlines may allow power banks with capacities between 100Wh and 160Wh with special approval, but anything exceeding this range is typically prohibited.
To determine the capacity of your power bank in watt-hours, you may need to convert the mAh rating. For example, a power bank with a capacity of 10,000 mAh and a typical voltage of 3.7V would have an approximate capacity of 37 Wh, which is well below the allowed limit.
Anker offers a range of power banks that comply with these regulations. The Anker Nano Power Bank 10,000mAh, for instance, is compact and affordable, making it a popular choice. Additionally, the Anker 737 Power Bank and the Anker Laptop Power Bank (25K, 165W) are also allowed on planes and provide higher capacities for charging multiple devices simultaneously.
In summary, when travelling with a power bank, ensuring it adheres to the capacity limit of 100Wh or 27,000mAh is crucial. By following these guidelines and checking the specific regulations of your airline, you can confidently bring your power bank on board and stay charged throughout your journey.

Calculating watt-hours: Convert mAh using a formula
When choosing a portable power charger for air travel, it's important to check the airline's specific regulations on lithium-ion batteries, as well as any restrictions on the size and capacity of power banks. Power banks are typically allowed in carry-on luggage but not in checked baggage due to the risk of fire caused by lithium-ion batteries.
The capacity of the power bank is usually limited to 100 watt-hours (Wh) or around 27,000 milliampere-hours (mAh). Power banks between 100Wh and 160Wh may be permitted with airline approval, but anything over this is usually prohibited.
To check if your battery pack complies with regulations, you need to convert mAh to Wh using a formula. Wh measures the amount of energy that a battery can deliver over time, while mAh measures the battery's charge capacity, indicating how much electrical charge it can supply at a given voltage over time.
The formula to convert mAh to Wh is:
Wh = (mAh x V) / 1000
For example, most power banks use lithium-ion batteries with a typical voltage of 3.7V. If you have a power bank with a capacity of 10,000mAh, the calculation would be:
Wh = (10,000mAh x 3.7V) / 1000 = 37Wh
So, a 10,000mAh power bank is allowed in carry-on luggage as it falls below the 100Wh limit. Similarly, a 20,000mAh power bank would be approximately 74Wh, which is also within the allowed range.
It is always a good idea to check the specific airline's regulations before travelling to ensure that your portable charger is allowed on the plane.

Power banks vs. spare batteries: The former is allowed in carry-on, the latter isn't
When it comes to air travel, it's essential to be aware of the regulations surrounding power banks and spare batteries. While both are convenient for keeping your devices charged on the go, there are important distinctions in how they are treated by airlines and aviation authorities.
Power banks, also known as portable chargers, have become increasingly popular among travellers due to their convenience. Most commercial airlines allow passengers to carry power banks in their carry-on luggage. This includes popular options like the Anker PowerCore 24K and the Anker Laptop Power Bank. However, it's important to note that power banks are typically not permitted in checked baggage due to the risk of fire associated with lithium-ion batteries. To ensure compliance, travellers should always check the specific regulations of their airline, as well as aviation authorities like the FAA and IATA, before their journey. These regulations often include capacity limits for power banks, typically capped at 100 watt-hours (Wh) or around 27,000 milliampere hours (mAh).
On the other hand, spare batteries, including uninstalled lithium-ion and lithium metal batteries, are strictly prohibited in checked luggage for safety reasons. These batteries must be carried in carry-on baggage, and any spare lithium batteries must be protected from potential short circuits. While some airlines may permit larger spare batteries (101-160 Wh) with prior approval, it's important to note that this isn't always guaranteed, and travellers should be prepared to comply with any restrictions.
The distinction between power banks and spare batteries is crucial when planning your travel gear. While power banks are generally allowed in carry-on luggage, spare batteries are subject to stricter regulations due to safety concerns. By understanding these differences, travellers can ensure they comply with airline regulations and have a smooth journey while staying connected. Remember to always check the latest guidelines from your airline and aviation authorities to stay informed about any updates or changes in policies.
