Power Banks

Capacity in mAh is not a structured field on the largest B2B marketplace — it survives there only as a variant label and as free text stuffed into titles. Here it is a real attribute you can filter on, and the watt-hour rating is computed from it by the database rather than typed, so the figure and the freight consequence beside it can never disagree. What that buys you in practice: you can tell before you enquire that a 20,000 mAh bank at 74 Wh ships under IATA PI 965 Section IB while a 27,000 mAh one at 100.4 Wh crosses into the fully regulated Section IA. Both are cargo aircraft only — a power bank is a battery travelling on its own, so the section is what moves the rate, not whether it flies at all. That is usually the difference between a workable quotation and a wasted week.
