What this means for flying

Below threshold

This model is comfortably below the common 100 Wh threshold. You still need a trip-specific check because country, airline, recall, and carry-on rules can add stricter conditions.

This is a catalog-level hint, not a final travel verdict. Final checks depend on the route, airline, recall status, and current rules.

How this Wh value is supported

This model uses a derived rating: 21,000 mAh × 3.70 V ÷ 1000 = 77.70 Wh, stored as 77.70 Wh in the catalog.
