Most people have heard that you are not supposed to bring lithium-ion batteries on planes, but did you know that this also includes power banks? Power banks are devices used to charge electronic devices, such as phones and laptops. They usually have a lithium-ion battery inside, which is what is not allowed on planes.
So, how can you tell if a power bank is allowed on a plane? There are a few considerations to make. Today, we're going to help you know whether or not you can bring your power bank (or banks) along with you on your plane ride:
Can I Carry My Power Bank on a Plane?
If you're planning to bring a power bank with you on a plane, there are a few things you need to know.
First, most power banks are considered lithium-ion batteries and are subject to the same restrictions as other lithium-ion batteries. This means that they can only be carried in your carry-on or checked baggage and not in your pockets or on your person.
Second, power banks are subject to the same size and capacity restrictions as other lithium-ion batteries. This means that you can only bring power banks that are less than 100-watt hours (Wh) in your carry-on or checked baggage.
Finally, power banks must be placed in a secure, well-ventilated area of your baggage. This means that they should not be placed in your pockets or in an area where they could be crushed.
If you follow these guidelines, you should be able to bring your power bank on a plane without any problems. However, it's always a good idea to check with your airline before you travel to make sure that they have no additional restrictions. Some may be more lenient, while others may be more strict.
Can I Bring My 20000 mAh Power Bank?
In some cases, you can. However, most airlines follow the 100 Watt-hour limit. As such, you should check if your power bank is lower or equal to 100 watt-hours and not anymore.
If you cannot find this in your power bank's specification, you should do a little map. First, get your mAh number, then find the voltage. Divide the mAh number by 1000 to convert it to amp hours (Ah). After that, multiply the Ah by the voltage, and then you get watt-hours.
Generally, if you see that your power bank is 3.6V or 3.7V and your power bank is less than 28000 mAh, you should be okay. Again, check with the airline to be 100% sure!
Can I Bring Multiple Power Banks on a Plane?
Usually, you can. While you can't bring a single power bank that exceeds 100 Wh, you can bring multiple power banks that do not exceed that number individually but add up together to over 100 Wh. Again, check with the airline.
Conclusion
So, if you find that your power bank is less than 100 Wh, there's not much to worry about. That's the general rule with most airlines, but if you aren't sure, you can't go wrong checking with the specific airline you're flying with. Just be sure to carry them in your carry-on luggage for safety reasons. While a fire in the cabin will be frightening (though it rarely ever happens), it is much better to deal with a power bank that fails there versus one in the cargo hold that slowly grows in fire!
