I need some help choosing my first power bank. I've seen some brands like iniu, Anker or ugreen, but I've also read about some Anker catching on fire.

I want my power bank to be around 30-35 v and 20k mAh and less than 50 euros (if the product is perfect I'm willing to pay more but I prefer to stay in budget).

Which one would you recommend if I want to buy one good product and forget about buying another one in a very long time?
