For the price (I bought for 450Kč) probably ok lighter powerbank for emergencies on the go. But don't expect any miracles. The 10000mAh capacity is declared for lithium cell(s) at ~3.7V. The resulting capacitance is therefore much lower (due to the conversion to 5V+) and losses on the converter+cable.
I measured a capacity of 6190mAh at a consumption of 12.5W (5V/2.5A) which corresponds to an efficiency of about 84%. So the cell probably does have about 10Ah nominal capacity, but expect a maximum of one full charge for a larger phone when charging at slow charging. Fast charging (more than 5V PD) will unfortunately be even worse.
Overall, I rate it positively; ) If you need more real capacity, buy the thicker 20000mAh.
Size, weight, design
Pretty funny little cable as a keychain
The voltage and current indicator is a bit of an unnecessary waste of energy, as it lights up all the time during discharge.
Wouldn't a higher PD power (e.g. 45W)

I don't know if I've had terrible luck. But I've had four pieces pass through my hands. Only one was okay. The others beeped, the voltage fluctuated, the charge on the display did not correspond to reality. Even the best piece squeaks and the voltage around 30% charge fluctuates a lot. Which is not good for the facility.
They should have limited the power to 65W, then it would have been usable. I don't recommend for 100W because of the bad current. It will reduce the endurance of the device.

It is listed as having a capacity of 10000 mAh (37 Wh), which evokes the use of a standard Li-ion (NMC) cell at 3.7 V. After a full charge, I connected the load to 5 V (CC) and discharged with 0.5 A. This way I was able to squeeze 32.2 Wh out of the claimed 37 Wh from the powerbank. This corresponds to 87%. Voltage conversion efficiency and losses are usually around 10%, so everything fits.
All parameters fit
Pleasant shape without sharp edges
Display - makes it easy to keep the capacity at appropriate values during storage
