I bought it for my son to keep his phone from going dead outside. I got the same one, but 20,000. I'm satisfied.

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.
