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 has a manufacturer-stated energy rating of 74.0 Wh.
