What is the Purpose of a Power Bank?
The purpose of a power bank is to recharge battery-powered electronics when you’re on-the-go! A power bank can be small enough to fit in your pocket or they can be larger with a higher capacity.

What Does mAh Mean?
For rechargeable batteries found in power banks, the mAh shows how much charge the battery can hold, and how long it can power another electronic before needing to be charged.
How Do I Know My Power Bank Capacity?
If your power bank has 10,000 mAh, you would divide that by the mAh of the device you want to charge. A quick online search can tell you the mAh of your device if you aren’t sure or can’t find the battery. For example, an iPhone XS uses a 2,658 mAh battery. Using the equation, it would take 3 hours and 7 minutes of charging your iPhone XS before your 10,000 mAh power bank ran out of battery life.
What Power Banks Are Allowed on Planes?
The Federal Aviation Administration (FAA) does not allow any type of battery onboard an aircraft that exceeds 27,000 mAh. Keep these guidelines in mind before flying and be sure to properly pack your power banks!
