Brandgefahr in großer Höhe: Powerbank im Flieger: Anzeichen und Regeln für kaputte Akkus

In-flight powerbank fires pose a significant safety risk, as demonstrated by recent incidents involving Lufthansa and Ryanair aircraft. To prevent such accidents, passengers must adhere to airline regulations regarding powerbank transportation. These guidelines vary between airlines, with some allowing only two powerbanks per passenger, while others permit up to two devices with a capacity of 100 watt-hours (Wh) or less. Exceeding these limits requires the powerbank to remain on the ground.

The primary concern with powerbanks is the risk of internal battery failure, which can lead to fires, especially if left unchecked during flights. Lithium-ion batteries, commonly found in powerbanks, e-cigarettes, and other portable devices, should not be placed in checked luggage, as any internal issues could go undetected and result in a potentially catastrophic fire. Instead, these devices must be carried on in hand luggage, where they are more easily monitored and controlled.

Airline policies on powerbank usage during flights also vary. Some airlines only permit the use of powerbanks but prohibit charging devices like smartphones, tablets, or headphones. In such cases, passengers are prohibited from charging any devices, including the powerbank itself. Charging a powerbank at a seat's power outlet may also be forbidden. In some instances, airlines require passengers to keep the powerbank within easy reach throughout the flight, meaning it cannot be stored in checked baggage.

To ensure the safety and functionality of their powerbanks, passengers should be aware of the following signs that the device may be malfunctioning:

1. Frequent charging cycles with visible damage

2. Excessive heat generation during use

3. Physical deformation or discoloration around connectors

4. Exposure to high temperatures prior to the flight

When purchasing a new powerbank, it is essential to consider the following factors:

1. CE and GS certifications, ensuring the device meets minimum safety standards

2. Manufacturer-provided data and technical details

3. Built-in protective features against overcharging, deep discharging, or overheating

Many low-cost devices or those purchased from online retailers may lack these essential safety functions. By adhering to these guidelines and examining powerbank condition before boarding, passengers can help ensure a safe and enjoyable in-flight experience.
