Can your powerbank fly with you a plane? Check what capacities are allowed, where you need to hide it and what surprises are waiting at the airport.
Powerbanks and planes – what exactly is allowed to bring on board?
Packing on travel is often stressful in itself – especially if we rarely fly by plane and do not know what to prepare for. When we add a handful of unclear recipes, regarding electronics, preparations for the trip become even less pleasant. One of the devices that raise the most doubts is Powerbank. You can not prepare for everything, but it is worth complying with a few basic rules to avoid surprises at the goals. In the era, when we feel like a hand without a phone, and the sockets in aircraft do not always work, taking a power bank on board is a obvious decision for many. What to look for? We suggest.
Why are there restrictions at all?
Powerbank is nothing but a set of lithium-ion batteries enclosed in one housing. The problem begins when something goes wrong. Just overheating or damage to the cell to cause so -called “Thermal Runaway” – an avalanche chemical reaction that ends with fire, smoke and of course stress on board. Sounds dramatic, but such situations really happen. According to reports, in January 2025 it was Powerbank that led to a fire on board Air Busan. This is one of the incidents that led to the fact that many airlines have decided to tighten the rules. Here, however, we come to the most problematic issue. How many airlines, so many different regulations.
In some aircraft Powerbank must be turned off throughout the entire flight. There are also regulations saying that PowerBanki must not be kept in the compartment above the head. They are to be under the seat or in the pocket of the chair. The point is that the crew could react immediately if something began to smoke. However, such requirements are still rare, but it is worth knowing about it and it’s best to get acquainted with the guidelines of the carrier who takes us on a journey.
Powerbank on the plane: What do the recipes say?
Let’s start with the principle that functions at every airport: Powerbank can never get to the checked baggage. There are no exceptions in this field. If the powerbank lights up in the luggage hatch, nobody will notice it until it is too late.
What can you take with you?
As I wrote earlier, each airline has its own regulations, but the most common standards are as follows:
- Powerbank up to 100 Wh (i.e. up to 27,000 mAh) – You can take him on board without a problem, as long as he is in hand luggage.
- Powerbank from 100 to 160 Wh (i.e. up to approx. 43,000 mAh) – up to two pieces, but often only with the consent of the airline.
- Powerbank over 160 Wh – Most often it is no longer allowed.
How to convert mah to WH?
Most of the powerbanks have something like “20,000 mAh” on the housing and that’s it. The problem is that the regulations operate in WH units. Fortunately, the pattern is simple:
- Wh = (mah × voltage) / 1000
For a voltage of 3.7 V (i.e. the most common), it looks, for example, in this way:
- 10,000 mAh = 37 Wh
- 20,000 mAh = 74 Wh
- 300,000 mah = 111 Wh
You don’t have this information on the housing? Look in the documentation or on the manufacturer’s website. It is important because some airlines can refuse to transport if the capacity cannot be verified.
Not all airlines allow the same
The fact that the flight or Lufthansa allow you to transport a 100 Wh powerbane without paper -free, does not mean that in China Eastern will be the same. In Asia, the situation is more tense – some lines require special certificates (e.g. 3C in China), others do not allow you to use powerbanks at all during flight. The rule is always the same: Check the page of a specific carrier.
What to do on security control?
On safety control, you must usually remove the powerbank from luggage and put it separately on the tape – just like a laptop or tablet. Make sure:
- Powerbank is clearly described (capacity in mAH or WH),
- there is no visible damage,
- is partially charged (services can ask for its inclusion),
- You have documentation with you if it is a larger capacity model.
Powerbank regulations in aircraft will probably be even more tightened – this is unfortunately the safety price in aviation. With a little preparation and knowledge of current rules, your energy supply can easily accompany you on travel. You just need to know what a carrier requires.
