Will TSA and Qatar allow carrying multiple power bank?
They are gift - will be kept in my backpack.
Is six powerbanks or 12 is too many to carry?

"Spare batteries are allowed only in hand baggage and must be individually protected to prevent short circuits. Power banks and similar devices are considered batteries and are subject to the same restrictions. All lithium batteries must comply with UN regulations"

"You can bring a maximum of 15 PEDs. For lithium batteries, the watt-hour rating must not exceed 100 for lithium-ion batteries, and the lithium content should not exceed 2g for lithium-metal batteries."

"You are allowed to carry up to 20 spare batteries"
