The Holiday season is on and we all will fly to different places to reunite with our family for the X-Mas celebration. With this many people are asking about the restriction when it comes to flying with power banks.
Mighty Gadgets wants to try to help so here is our guide:
Are Power Banks Allowed on Planes?
In short, yes you can fly with most power banks. That’s great news if you’re in need of a quick recharge when you touch down or if you’d like to be able to do work when 40,000 feet in the air. However, like all great things there is a catch. First, power banks, which use lithium-ion batteries, need to be stored in carry-on baggage only. Second, power banks over a certain size cannot be brought onto flights at all.
What Sized Power Banks Are Restricted?
The restrictions as per the Federal Aviation Administration are for lithium-ion batteries rated above “100 watt hours (Wh) per battery”. Anything above that limit is restricted. While that limit allows most power banks to be brought on flights, there are still consumer power banks that exceed that limit. Thankfully some airlines, with prior approval, will allow power banks rated between 100.1-160 watt hours to be taken onboard.
How Is Wh Calculated?
Calculating the watt hours of your power bank is particularly easy and can be done with your phone’s calculator or even in your head. Here’s the formula:
(mAh)/1000 x (V) = (Wh)
In other words, Milliamp Hours/1000 x Nominal Voltage = Watt Hours
This means our 26800mAh Power bank is the largest power bank in our collection that can still be taken in board.
26800mAh/1000 x 3.7V = 99.16Wh
When using RAVPower’s 32000mAh Power Bank:
32000mAh/1000 x 3.7V = 118.4Wh
As it’s over the limit, you would need approval from the airline to bring it on board.
While these are the rules as per nearly all major airlines, some airports have their own rules that may differ from the rules listed here.
