In our tech-savvy world, power banks have become essential accessories to keep our devices charged while on the go. Whether you’re traveling for business or leisure, having a reliable power bank is a lifesaver. However, it’s crucial to know the rules and restrictions surrounding power banks when you’re embarking on international flights.
The International Air Transport Association (IATA), a prominent international aviation organization, has established specific guidelines for traveling with power banks. Let’s delve into the details and understand what size of power banks are allowed on international flights.
The IATA Rules for Power Banks
According to the IATA regulations, passengers are generally permitted to carry up to two power banks during their flights. These power banks are subject to specific size and capacity limits to ensure safety onboard aircraft.
Size and Capacity Restrictions
The combined capacity of the two power banks should not exceed 27,000mAh or 100 Watt-hours (Wh). It’s important to note that this limit applies to the total capacity of both power banks. This capacity restriction is put in place to minimize the risks associated with lithium-ion batteries, which are commonly used in power banks.
But what does this mean for travelers? Let’s break it down further.
Understanding Capacity: mAh and Wh
Power banks are typically rated in terms of milliampere-hours (mAh) and Watt-hours (Wh). These ratings help you gauge how much charge your power bank can provide to your devices.
- mAh (Milliampere-Hours): This measurement reflects the power bank’s capacity to provide a certain amount of electrical charge over time. For example, a 10,000mAh power bank can deliver 10,000 milliamperes of current for one hour.
- Wh (Watt-Hours): Watt-hours represent the total energy capacity of a power bank. It’s calculated by multiplying the voltage (V) by the capacity in ampere-hours (Ah). For instance, a 20,000mAh power bank with a voltage of 5V provides 100Wh of energy (20,000mAh x 5V = 100Wh).
Examples of Permitted Power Banks
- A 20,000mAh power bank is generally allowed in international flights. As 20,000mAh equates to less than 100Wh, it can be safely carried in your cabin luggage.
- Similarly, a 10,000mAh power bank is acceptable for travel. The 10,000mAh capacity equates to 50Wh (10,000mAh x 5V), which is well within the 100Wh limit.
Beyond the 100Wh Limit
However, if you possess a power bank with a capacity that exceeds 100Wh, like a 30,000mAh power bank, you will require airline approval to carry it on the plane. It’s essential to communicate with your airline well in advance to seek permission and adhere to the specific regulations.
Safety First: Understanding the Rules
Power banks are essential travel companions, but it’s crucial to prioritize safety. Keeping power banks within the allowed size and capacity limits helps ensure a secure flight experience. If your power bank is within these limits, you can comfortably keep it in your carry-on luggage.
It’s also important to remember that when carrying power banks in your hand luggage, they must be completely switched off during your flight to prevent any accidental activation. However, if your power bank is installed within a device, it may be carried in checked baggage.
By understanding these rules, you can ensure a hassle-free and safe journey with your power bank during your international adventures. So, pack your power bank wisely, stay charged, and enjoy your travels with confidence.
