What this means for flying

Above 100 Wh

This model is above the common 100 Wh threshold, so it should not be treated like an ordinary carry-on power bank. Run the trip-specific verification before relying on it for travel.

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: 40,000 mAh × 3.70 V ÷ 1000 = 148.0 Wh, stored as 148.0 Wh in the catalog.

Identity notes

Also known as

B731

Official CHOETECH product page URL identifies CHOETECH B731 Pd22 5w DUAL USB A TYPE C POWER BANK 40000mah BLACK and states 40000mAh capacity. Wh is derived from nominal 3.7V because the official page URL/title evidence does not publish a durable Wh value.
