What capacity (mAh) should I choose when buying a power bank? What's the difference between 10,000 mAh and 20,000 mAh? Does it charge my phone just once or extend its battery life more? In which situations is which capacity more reasonable, bro?
How does power bank capacity affect performance?

Thanks for sharing. I've also been looking at 20,000mAh power banks, but I guess a 10,000mAh one is usually enough for regular use.
