In our increasingly connected world, taking a power bank on the plane has become almost a necessity for many travelers. But, can you always take a power bank on board?

In this blog we discuss what you need to know about an airplane power bank , from capacity to useful tips. This way you are well prepared and you can be sure that your power bank can travel with you.

1. Airplane power bank: Limit of 27,000 mAh

When traveling by plane, you are allowed to take power banks with you in your hand luggage. However, there is an important limitation regarding the total capacity: you are allowed to carry two power banks with a combined capacity of no more than 27,000 milliamp-hours (mAh). This means you'll need to pay attention to the capacity of each individual power bank to ensure you stay within this limit. This rule was introduced to ensure safety during flight and is applied by most airlines and according to international aviation guidelines.

2. We recommend this power bank!

For those looking for a reliable power bank for use during air travel, we recommend the R2B Power Bank with a capacity of 20,000 mAh. This power bank falls within the allowed limits for airlines, which means you can take it with you in your hand luggage without worry. With its capacity of 20,000 mAh, it provides enough energy to charge your devices several times, without the need for a socket.

Bring a power bank? Tip: Place it at the top of your hand luggage

Do you want to take a power bank with you on the plane?: always place the power bank at the top of your hand luggage. This not only ensures easy accessibility during airport security checks, but also eases the process if the airline or security personnel want to inspect your luggage. By keeping your power bank at the top, you avoid having to unpack all your belongings and you can quickly demonstrate that your power bank complies with the set rules and capacity limits.

3. Converting from mAh to Wh: An Important Step

When preparing for your flight with power banks, it's important to know how to convert milliamp-hours (mAh) to watt-hours (Wh). This conversion is crucial because some airlines indicate their limits for power banks in Wh instead of mAh. The formula to convert mAh to Wh is relatively simple: multiply the capacity of the power bank in mAh by the voltage in volts (V), and then divide this number by 1000.

For example, if a power bank has a capacity of 10,000 mAh at a standard voltage of 3.7 V, then the capacity in Wh is: 10,000 x 3.7 / 1000 = 37 Wh.
