Why is my power bank providing fewer charges for phones than expected?

Power bank loses 30%-45% energy as heat during charging due to cable resistance and internal circuitry. A fully charged 20000mAh bank provides about 11000mAh-14000mAh to devices.

How to activate 165W Max "beast mode"?

Pair Type-C1 with a 100W+ PD adapter and Type-C2 with a 65W+ PD adapter. Both ports charge simultaneously, reaching ~70% in 20 minutes at ambient temperature (25±2℃).

Is this power bank allowed on flights?

Yes, this power bank is under 100Wh, meeting TSA requirements for carry-on luggage.
