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: 20,000 mAh × 3.70 V ÷ 1000 = 74.00 Wh, stored as 74.00 Wh in the catalog.

Identity notes

Official BOROFONE product page URL identifies POWER BANK Bj20a 20000mah and states 20000mAh capacity. Wh is derived from nominal 3.7V because the official page URL/title evidence does not publish a durable Wh value.
