What this means for flying

Near 100 Wh

This model sits close to the common 100 Wh threshold. A clear printed Wh label matters more here because an unclear label can trigger conservative handling at security.

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: 27,000 mAh × 3.70 V ÷ 1000 = 99.90 Wh, stored as 99.90 Wh in the catalog.
