mac air m2 charges from 30% to 70% in 25 minutes, the mac was connected to an external monitor
even with the cable attached, this mac/ipad is charging faster
the connectors are robust and the power bank has a good overall quality
bigger and heavier than I expected - it is not a power bank for travelling, because of its size

After measuring all the values with a usb wattmeter, I must admit that it is admirable that the powerbank almost reaches the advertised 146Wh. My measurements, which consisted of charging one device at 5V (90% capacity) and alternating 9V (10% capacity), I concluded that the powerbank delivered 134Wh to my devices, which after adding small, but not insignificant, losses corresponds to the advertised capacity. The problem occurs when charging at higher voltages. At 12V voltage, charging starts to be more lossy and at 20V/5A the powerbank is already heating up significantly, the temperature exceeds 30°C. Heating results in lower effective capacity. A 74Wh laptop with a powerbank can be charged 1.25-1.5x, although theoretically it should charge 1.97x. The powerbank itself can be recharged really quickly, that's a big plus. For interest roundtrip efficiency, the ratio of watt-hours charged by the power bank to watt-hours delivered by the device, is 71%, which also shows high efficiency of charging in both directions.

Fast charging of the powerbank itself
100W charging wastes part of the capacity by heating

I am extremely satisfied with the product. It meets everything I expected and I can definitely recommend it!
Excellent capacity and charging speed
Can also charge a laptop
Slightly higher (but completely understandable) product weight

unlike another review I have to say that it works from the first unpacking and excellently
if you want the power supply as a backup power source for working from home or when travelling preferably by car, I can recommend it
this is to be expected with 40,000 mAh, no surprise: the source is big and heavy. Nothing for hiking.
apparently for the sake of battery life, the manufacturer recommends charging with a weak 5V/2A power supply. With one of these it takes a very long time to charge (15 hours according to the manual)

Lovely design
Does not work right after purchase - after charging via USB-C, charging from USB-C does not work. After half an hour of examining the manual and various combinations of plugging in the cable and pressing that one button, I conclude that it's rubbish, I return it.
