Why is realme's charging treasure so cheap and reliable?

It's just that I have a realme charging treasure now. I have been using Xiaomi's charging treasure, because I bought it early, only the Micro USB interface has no Type-C interface. Every time you charge the charging treasure, you need to prepare another Micro USB cable. Realme's charging treasure is my first large-capacity charging treasure, 10000mAh. Let's talk about its advantages: 1 and 10000mAh can be charged twice (usually when there is no electricity), which is more than enough for daily use. 2, charging treasure shell grid texture design, not easy to contaminate fingerprints, to prevent slipping. 3, curved surface design, rounded edges, fit the palm of your hand, feel comfortable, about the size and thickness of a mobile phone, and the weight is similar to that of a mobile phone. 4, dual input, two different ports, better compatibility. Dual output, which can charge two mobile phones at the same time. In addition, the low current charging mode is very friendly to the popular wireless headphones.

However, there are many things to complain about. 12w power is really stingy, which is almost the same as my new mobile phone 33W for one day. And the total power of dual output is only 12w. Who will charge two devices at the same time with such power? In addition, the overall length is a bit long, and it will be more harmonious if it can be shortened by 2cm. But overall, the quality is reliable, which does not mean that there is no good product if it is cheap, and it is worth the money.
