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℃).

B**.

Best power bank

The quality of the power bank is good. Its strongest point is beast mode, which helps charge very quickly. The three out gates are truly unbelievable. It's very easy to use. It would be perfect if it were a little lighter.

Found out by accident.

the cable you use makes a difference. The display tells you the capacity of the cable when you start to charge. The supplied cable is 6A but the ones I already had were only 3A.

It has a Beast Mode! Excellent power bank.

This Power Bank is a beast in a few ways. It can charge other devices very quickly and it can be charged extremely quickly. This is a 20,000 mAh Power Bank that puts out enough power to charge a laptop. It has one of the nicest LED screens I've seen on a Power Bank. Not only does it tell me what charging port is in use, but it also lets me know the amount of power going out to each device.When charging the Power Bank itself, the 'beast mode' can be activated by connecting two separate USB C power sources. Ideally one 100W and one 65W. Connecting two USB C cables charges this Power Bank significantly quicker.The footprint of this bank is small, its rectangular in design and small. Very portable.Not much is needed to understand about this Power Bank other than that fact that it can have two input cables to charge it. Other than that it manages itself pretty well charging up everything as needed.
