Bringing external batteries/powerpacks to Egypt?
We will be traveling to Zurich on LX, to Cairo on Alitalia, inter-Egyptian flights on EgyptAir, transiting through AMM from CAI to DOH on Royal Jordanian, and home to the US from DOH on Qatar. I have been reading that some airlines will not allow external batteries/powerbanks that I expect will be essential to keeping my phone and camera charged during our 15 day trip. I always have at least one powerbank on me at all times here at home.
I can't find anything specific on the airlines' websites that we will be traveling on about guidelines for powerbanks/external batteries. Has anyone heard of any of these airlines making you relinquish your powerbanks?
