I was going to post something similar to this question.
I've got one that's 8000mAh with 300A peak as it's also a car battery jump starter, would there likely be any issue taking this.
Cathay Pacifics website says power banks are ok in hand luggage but doesn't say anything about this particular kind.
Fine. I've just this moment gone through airport security and had my bags checked because I'd kept my leatherman in my hold luggage power bank fine, mine is one of the Anker 20k hobbies.
Is that 8000mAh at like 11.x volts or something? should be just under the limit but you might be limited to only 1 battery/bank.
Never even thought about this, I fly pretty much every month both long and shorthaul with a couple of power banks (one is massive) and they have never been looked at. Will check I'm not over the limit next flight!
I honestly don't know, just scoured the Amazon page and can't find any voltage detail.
I only want to take this one when I go out to Indonesia, I can't see there ever being more than 24 hours when i'm away from a mains socket but would rather have it all the same.
