For the price, it' s a pretty good powerbank. my only regret is that it was in the laptop section, but instead of buying it, it charges itself. It was purchased in order to extend the life of the laptop.
capacity
several types of USB
laptop won' t charge

MacBook Pro 16“ (2019 model) charges with a voltage of approx. 8.67V and a constant current of 2.15A (~18.6W). (In another port, the Mac only supplied about 4.4V, but I think with a higher current, I haven' t tested that properly. ) As it approaches discharge, the voltage starts to drop to ~7.51V, then shuts off. It' s a shame that she didn' t agree on a higher voltage with Mac, but it wasn' t far from the maximum supported 20W at 12V. In total, it lasted 3 hours and 11 minutes and even charged the laptop by a few percent during light work. After full charge and first discharge, I measured a capacity of approximately 58.68 Wh at room temperature, which is about 80% of the stated capacity of the cells. That the converter losses would be 20%, or is the cell capacity smaller, or a measurement error? We will see how the capacity will change over time and if the efficiency is better without fast charge.
Price
Although not an advertised feature, “pass through“ almost seems to work: when charging via USB-C from a 20W charger, it powered my devices connected to the USB-A connector of the power bank. But when disconnecting/connecting the charger, it interrupted the output for a while, so it is not suitable “as a UPS“ for devices without its own battery. It seems that it cannot fast charge in this mode (the green LED goes out).
The included microUSB cable could be replaced by the subjectively more useful USB-C
Attention: holding the button for 10s not only turns off the power bank as written in the manual, but also forgets that it is charged and needs to be charged again (although this is faster than charging from a truly discharged state)

the first one purchased did not hold its capacity, I bought it fully and it was exhausted in a day, after a complaint with the second, the same problem. Definitely the worst product I have bought in the last few years

Decent capacity
Good price
USB-C combo port
Appearance
Higher weight
I do not recommend switching off by pressing the switch for 10 sec. Then the power bank does not show the real state of charge. After connecting to the network via Micro USB and at the same time connecting the charging device, the status of the lights is reset and they show correctly again. No need to turn off the power switch. Without a device connected, it switches itself off.
