I connected lenovo thinkpad x1 via a typeC cable with QC purchased separately (It also works through the cable from the kit). When working on a laptop, its own battery does not change the charge level, while the power bank is discharged. In sleep mode, the laptop is charging. In the operating mode, Internet + video from YouTube, in the maximum power consumption mode with a screen brightness of 60%, it was discharged by 50% in 4 hours, that is, a full charge of the can should last for 8 hours. Before that, I bought xiaomi powerbank 3 (not pro), it only charged the switched off laptop, and during operation it was discharged.
