As long as mobile phones continue to have batteries with less than 24 hours of life, we will have to continue using external batteries with which to give our device a boost of energy. This is especially necessary on vacation, since when we travel we tend to use our cell phones much more, to talk to family, follow GPS directions or look for a restaurant to eat. Given that carrying an external battery is almost essential, what limitations are there for taking one on a plane?
The key is in the capacity
Due to the risk involved in accumulating high-capacity batteries, airlines have very strict limitations when it comes to accepting external batteries in the aircraft cabin, and even in the hold. Normally, when checking in online, the company you fly with reminds you of its rules, and it is quite common to see the guidelines regarding external batteries or Power Banks.
The key is usually the total capacity of the battery, since most airlines They limit this value to 100 Wh. This is a figure that you can see on one of the sides of the battery, although it can also be seen in mAh, which usually corresponds to about 27.000 mAh.
Each passenger may carry a maximum of 2 external batteries, and none of them may exceed 100 Wh. Drone batteries are also specified, which are regulated by the same rule, and cannot exceed 100 Wh. The airlines do not specify whether it can be combined in number with external batteries, although we imagine that in the global calculation the measure tries to limit a total of 200 Wh per passenger.
Laptop batteries, electric scooters and other devices
The bulkier battery models are the real problems. You won't have any problems with laptops, but forget about transporting electric scooters or any other variant. All types of scooters or devices with wheels that serve as a means of transportation are prohibited, since their batteries are highly dangerous.
The famous smart suitcases with integrated batteries are also not allowed. Airlines require passengers to remove batteries so they can carry them in cabin luggage. Whether checked in or not, the batteries in these suitcases must always be removed from the suitcase itself.
Each airline has its rules
The most advisable thing is that if you have batteries and think you might have problems, consult the official website of the airline you fly with so that you know in detail the rules that this company establishes on its flights. This way you will avoid any scare in case you have to forget your battery out of obligation.
