Can I Bring My Power Bank on Planes?admin
With all the excitement going on in your digital devices, power bank is a must have for both daily life and travel. Nobody wants to wait a delayed airplane with a dead phone, or land in an unfamiliar city holding a phone with only 5% battery left. Just imagine that!
Before you pack your power bank with your travel essentials, you may be wondering if your power bank is allowed on planes. Can I take a power bank in carry-on luggage? Is it cabin luggage or hand luggage?
Besides, there are various capacities power bank from 1000 mAh to tens of thousands mAh. Is there any limitation of power bank capacity on planes?
All your confusions can be ended today.
The International Air Transport Association (IATA) points out:
“Spare (uninstalled) lithium ion and lithium metal batteries must be carried in carry-on baggage only. Lithium ion (rechargeable) batteries are limited to a rating of 100 watt hours (Wh) per battery. These limits allow for nearly all types of lithium batteries used by the average person in their electronic devices.”
Most of the power bank is labeled mAh. So how to calculate Wh?
Here is how: (Wh) = (mAh)/1000 x (V)
The last parameter, V, is also called Nominal Voltage, which is normally 3.7V for most of the lithium-ion cell.
Take a ROMOSS Polymos 20 20000 mAh as an example. It’s 20000 mAh /1000 x (3.7V) = 74 Wh. And you can surely bring it in carry-on baggage, since it’s less than 100 Wh.
Above information covers most of the airline regulation. However, different countries may have different rules regarding power banks on airplanes. If you’re still worried about the regulation, the safest way is to check the website of the airport and search for their rules.
Travel safe and enjoy more!
