Why aren’t you allowed to take a power bank on a plane?
Power banks are limited on airplanes mainly due to safety concerns with lithium-ion batteries. These batteries may present a fire hazard if they malfunction or become damaged. Regulations are in place to minimize risks by limiting the size and capacity of external batteries that can be carried on board.
The risks of fire and the difficulty of managing them in flight justify these precautions.
Am I allowed to take a power bank on a plane?
You can take an external battery on a plane, but you must follow specific regulations.
Most airlines and aviation authorities allow external batteries in carry-on baggage, but place restrictions on their capacity. Generally, external batteries with a capacity of up to 100 watt hours (Wh) are permitted without special authorization. Larger power banks may require airline approval or be restricted entirely.
Is a power bank allowed on a plane?
The size of an external battery you can take on a plane is generally limited by its capacity, measured in watt hours (Wh).
Most airlines allow external batteries with a capacity of up to 100 Wh (approximately 27,000 mAh at 3.7 V) in carry-on baggage.
External batteries with a capacity between 100 Wh and 160 Wh may be permitted with airline approval, while those exceeding 160 Wh are generally prohibited.
When choosing an external battery to take on a plane, make sure it meets the airline’s capacity regulations.
As a general rule, external batteries with a capacity of up to 100 Wh are allowed in carry-on baggage. Always check the specific regulations of the airline you are traveling with, as requirements may vary. Some airlines may have additional rules or restrictions.
To convert 20,000 mAh to watt hours (Wh), use the formula: Wh = (mAh × V) / 1000. Assuming a standard lithium-ion battery voltage of 3.7 V, the calculation is: (20 000 mAh × 3.7 V ) / 1000 = 74 Wh.
This means that a 20,000 mAh power bank is approximately 74 watt hours.
We hope this explanation helps you to understand on Why aren’t you allowed to take a power bank on a plane? and answered your questions.
