  • Someone answered that the TSA rule limits spare (non-installed in a device) lithium ion batteries to 100 watts. That's not true. The limit is 100 watt-hours. And in most cases, the airlines will allow spare lithium ion batteries up to 160 watt hours. This unit is 70.875 watt-hours so it is well under the limit and permissible. One other thing to note: you cannot put them in checked luggage. They must be brought in your carry on (where if there is a problem with a battery malfunction it will be discovered immediately).

  • Answer

    Yes it is TSA approved. I have taken this battery pack, along with two others, on flights to London and Shanghai. While I was in China, the rules about external battery packs changed and I was questioned about it by TSA. The rule is that any external battery pack under 100w can be taken on a plane. This battery pack is 30w. They did initially state that they were going to confiscate them. I nicely and respectfully informed them of the rule; they checked the rule and allowed me to take them onboard.
