I bought it to power a Christmas nativity, in which a USB cable lights up 3 LEDs that shine on the characters. It proved to be unsuitable for this use. The power consumption of the crib is low, so the power bank switches itself off after a few seconds.
Relatively small, lightweight yet powerful
Status check with ice
Not functional for low load, at low load it shuts down the outputs after a few seconds!
Not suitable for powering doorbells, children's bedside lamps, toys with low power consumption, etc. In short, it's only good for charging your phone.

This 5000mAh powerbank is reasonable in size and weight. My son was constantly burning up his phone, but he didn't want a power bank. So this was a compromise choice so he wouldn't carry a big, heavy box. This one is fully sufficient for one emergency recharge. I consider the price to be average. It is too early for further evaluation. The power bank is a long term use item, so I hope it lasts a few years. What else to write. It is wittily solved charging cable. The power bank has 2 USB-C and Lightning connectors and a cable with both ends, so it's versatile and you can provide a little juice to a friend despite having a competing product.
The cable is not fixed.

Size
Good as a crash cart before it broke.
After five months the powerbank stopped charging, it cannot be charged to more than "one dot" (25% of capacity). Next, the side button stopped working.
The capacity absolutely does not match the power bank's performance. It charges a few tens of percent of your phone's battery.

I bought them for the RGB chairs. After 3 days, they completely discharge even when the RGB is turned off. The HVAC will spontaneously discharge in a few days. If one or two commas are missing, so be it, But it is reduced to zero.

As I wrote in the negative, the powerbank would be a lot more practical if it came with the now common USB-C port for charging. I feel like I've gone back 10 years with this power bank.
small and lightweight
The powerbank can only be charged with the outdated microUSB port, which I didn't notice when I chose it, it's quite annoying because you still have to have 2 types of cables with the powerbank
