good price
quite compact
From time to time, it's noisy when dispensing – a rushing or even a whistling sound.

Small and compact with a large capacity. And on top of that, it's also relatively light compared to similar solutions. Ideal for a backpack for a trip into town or into the countryside.

I bought this to use with the Meta Quest 3, where the battery life had rapidly deteriorated after two years, even in the strap I’d bought separately for it. So the solution is to buy a new strap for around 3,000 CZK or a battery for around 700 CZK, but according to the instructions, you have to take the Quest apart completely, which isn’t a good idea. The problem was solved by this power bank, which extended my usage time by about 4 hours. I’ve only had it for a short while, so I’ll have to put it through its paces. The PB not only manages to hold its charge whilst gaming, but also recharges it – and has been doing so very well so far.

I’m deducting two stars for the instructions. Caption:
1 LED indicator light
2 USB-C1 inputs/outputs
3 USB-A ports
4 USB-C2 inputs/outputs
5 Control button
and then it says: "Charging the power bank – Plug one end of the charging cable into the power bank’s USB-A port and the other end into the USB
the port on your laptop or network adapter. "
