Are you going on a plane trip soon and would you like to take a power bank with you? Smart! With a power bank you can charge your smartphone, tablet or e-reader on the go - ideal during long flights or transfers. But beware: There are rules associated with taking a power bank on the plane. In this blog we explain How many mAh a power bank can have on the plane, what to look out for, and provide useful tips for travelers.
In short: Until about 27,000 mAh (100 Wh) is never a problem for the plane, this is always allowed in hand luggage. Provided the mAh is stated on the power bank.
However, sometimes you can also take power banks with you with a larger capacity. When this is possible, you can read in the article below.
Why are there rules for power banks on airplanes?
Power banks contain lithium-ion batteries, which can be a fire hazard if used incorrectly or damaged. That is why there are worldwide regulations for taking power banks on planes. These regulations are usually set by airlines, but are often based on international guidelines from, for example, the IATA (International Air Transport Association).
The main limitation has to do with the capacity of the power bank, expressed in mAh (milliampere-hour) or Wh (watt-hour). The higher the capacity, the more energy the power bank can store – but also: the stricter the rules for taking it with you.
Taking a power bank on the plane? This is what you need to know
The answer to this frequently asked question depends on the capacity in watt hours (Wh)Most airlines have the following guidelines:
- Up to 100 Wh (approx. 27,000 mAh at 3.7V) → permitted in hand luggage, without reporting requirement.
- Between 100 Wh and 160 Wh (approximately 43,000 mAh at 3.7V) → often allowed, but only with permission from the airline.
- More than 160 Wh → prohibited in both hand luggage and checked luggage.
Please note: power banks are not allowed in checked baggage. So you should always have them in your hand luggage take along.
How do you convert mAh to Wh?
Most power banks only list mAh, but airlines look at Wh. You can easily convert it:
Wh = (mAh × Voltage) ÷ 1000
Most power banks have a voltage of 3.7V. A power bank of 20,000 mAh so it comes out to:
(20,000 × 3.7) ÷ 1000 = 74 Wh
And that is well below the 100 Wh limit, which means you can take it with you in your hand luggage without any problems.
Can you take multiple power banks with you?
Yes, but rules apply here too. The IATA stipulates that you can carry a maximum of two spare batteries between 100 and 160 Wh per person may take, with the permission of the airline.
For power banks under 100 Wh, like most standard models, there is usually no maximum number as long as it is for personal use. So if you are traveling with two or three people, for example 20,000 mAh power banks, then that is usually not a problem – as long as they are in your hand luggage.

What should you pay attention to when taking a power bank on a plane?
To avoid problems at the airport, it is wise to follow the tips below:
1. Take your power bank in your hand luggage
So don't put it in your hold luggage. This is prohibited and can lead to delays or even confiscation.
2. Check the specifications on the housing
Make sure the capacity (mAh or Wh) is clearly stated on the power bank. If this is missing, the security can be difficult.
3. Make sure it is charged (but not completely full)
Sometimes airline staff will ask you to turn on your power bank as a check, so make sure it has some charge.
4. Use a protective cover or anti-short circuit packaging
Protect your power bank from impact or short circuits, especially if you have other metal items in your bag.
5. Check your airline's rules
Although most airlines have the same guidelines, there can be minor differences, so always check your airline's website.

What happens if my power bank is too big?
If you have a power bank that exceeds 43,000mah, it can be confiscated at the airport. In some cases, it can be taken with approval, but you have to arrange that in advance.
Are power banks allowed on all flights worldwide?
IATA guidelines apply worldwide, but some countries (such as China or the US) may have stricter controls. Always check the policy of your departure and arrival country.
Summary
A power bank is essential when traveling, especially during a long flight. But you must adhere to the rules for taking electronics on the plane.The main question is.
In short: how many mAh power banks can I take on a plane?
