Does anyone know how large of a pack (I'd ideally like to bring 2) that they would reasonably allow? I aim to drive to Best Buy or Target tonight to get them.
The limit is 8 grams of Lithium content - the actual metal element. Don't bother with the chemical compounds, percentage calculations, etc. - the TSA limit is 100WH (unlimited) and 160WH (up to 2) in carry-on. (a translation of the 8g limit into a usable metric). I suspect Copa saying it must be "between" 100 and 160 is a poor translation of that rule (they're certainly not going to turn away a 90 WH/18K mAH device because it's not "between" 100 and 160)
For a standard 5V charger, 100/160WH is 20,000 and 32,00 mAH.
