Are battery packs allowed in hand luggage?

  • When flying, are you allowed to bring battery packs / power banks? I'd like to bring my ACC 10400mAh Power Bank on several flights.

    NB - Battery packs **MUST BE** in hand luggage.

    There are limits that were introduced by the US Federal Aviation Administration. Those have been used as well by numerous other airlines, for example Cathay Pacific. They generally impose a limit on capacity per passenger and on top of this disallow checking them in, so you must take them into your hand luggage.

    If a website lists grams of Lithium, use this formula (source):

    Equivalent Lithium Content (ELC). ELC is a measure by which lithium ion batteries are classified.

    8 grams of equivalent lithium content are equal to about 100 watt-hours.
    25 grams of equivalent lithium content are equal to about 300 watt-hours.

    You can arrive at the number of watt-hours your battery provides if you know how many milliamp hours and volts your battery provides: mAh/1000 x V = wh

    There is additional information available from the TSA and the IATA.

    Some more information here from Thailand, as of Jan 2015 (sorry, a bit shaky)L enter image description here Essentially, anything above 32'000 mAh is forbidden, below that and above 20'000 mAh is limited to 2 per person, below that there are no limits, but all only in hand luggage.

    I don't see the details as far as size in any of those links (outside of "grams of lithium content" which is NOT labeled on any battery afaik..)
