Power Bank Specs — Claimed Capacity, Output & Airline Compliance
Manufacturer-claimed capacity, rated Wh, max output wattage, ports and airline compliance for 18 popular power banks — sortable, with independent-teardown citations where we found one.
The hard numbers behind popular power banks from Anker, Ugreen, Baseus, INIU, Belkin, Mophie, Samsung, Zendure and Shargeek: manufacturer-claimed capacity (mAh), rated watt-hours, max output wattage, port configuration, charging protocol, weight, price and whether the rated Wh clears the 100Wh US carry-on limit. ChargerLAB's independent teardown measurements are editorial content we cite by URL per row (`testedBy`) rather than bulk-reproduce — see provenance below for why this table leads with manufacturer specs instead of a scraped measured-capacity table.
