For most Falklands travelers, a 10,000–20,000 mAh USB-C Power Delivery power bank gives a useful balance between capacity and baggage weight. More important than the marketing capacity is its watt-hour rating, output power and compliance with your airline’s lithium-battery rules.
Airline rules come first
IATA passenger guidance treats power banks as spare lithium batteries: they belong in carry-on baggage, not checked luggage. Up to 100 Wh is generally allowed for personal portable electronic-device batteries; 100–160 Wh requires airline approval, and airlines may impose stricter limits.
USB-C PD matters
Adequate USB-C output can charge modern phones, tablets and some laptops while reducing the number of separate accessories you carry. Check the output your device requires.
Cold and wet conditions
Lithium batteries can perform worse in cold conditions. Keep the bank protected from water and, when practical, inside an inner pocket rather than exposed in a cold external pouch.
Use watt-hours when comparing airline limits
mAh is convenient for shopping, but airline lithium limits are expressed in watt-hours. Reputable power banks print Wh on the case; keep that marking legible for travel. IATA guidance treats power banks as spare batteries carried in cabin baggage, while individual airlines can impose stricter conditions. Check every carrier on your route, including connecting flights.
