Where to charge your phone in public places?

I often go to shopping malls and cafes, and my phone runs out of battery at the most inconvenient moment. I don't always have a power bank with me, and it's hard to find a socket. Does anyone know any convenient ways to recharge in public places?

I encountered this when my phone ran out of battery at the airport and the outlets were occupied. That was the first time I tried a mobile phone charging station – I simply plugged in my phone and while I was drinking coffee, it charged up to 50%. Now such stations are installed in shopping malls, offices and even on the streets. They are convenient because you don’t need to carry a charger with you, and you can quickly recharge your phone when needed. If you often find yourself in a situation where your phone is dead, I recommend taking a closer look at such solutions!
