YSK power banks arent banned on flights, theres just a watt-hour limit
Why YSK: Always thought you couldnt bring power banks on planes at all. Turns out TSA allows them in carry-on as long as theyre under 100Wh. You just cant check them in luggage because lithium batteries in a cargo hold are a fire risk with nobody around to deal with it.
The math: mAh x voltage / 1000 = Wh. A typical 20000mAh bank at 3.7v is about 74Wh, well under the limit. Been flying for years with mine buried in my bag praying nobody would confiscate it. Turns out I was fine the whole time lol.
