Nowadays, the mobile phone has become a big power consumer. In the case of action use, it rarely uses the mobile phone, and can persist in a whole day's life. Therefore, more and more consumers are used to carrying a power bank to the mobile phone as their partner. So why is the price of the same milliampere power bank several times or even dozens of times different?
Let's take the ordinary 10000 Ma power bank as an example. If the power bank adopts inferior cell circuit boards or uses inferior materials in materials and safety protection circuits, its cost will be reduced. However, our consumers will fall into the probability of small probability of safety accidents. Therefore, no matter what the architecture of mobile borrowers is, We always have to consider its quality first.
In the power bank, whether it is its power management chip or boost circuit, conversion circuit, USB interface or charging line, all the components involved in the conversion have a certain conversion efficiency loss. It can also be said that the vast majority of the power bank, in fact, its actual charging capacity can have 70% of the label, has been regarded as a very excellent product in the power bank, and naturally its price will be higher than that of other power bank.
The most common factor that affects the price of some brands of power bank is the brand effect. For example, the specifications of Huawei and glory's 10000 Ma fast charging power bank are very similar, but the price of Huawei's power bank is a little higher, so part of the price is its brand value, so its price is naturally more expensive.
When we choose the power bank, we must choose the power bank of a big brand, but we should also analyze the cost performance of them. We should not blindly believe in the brand and ignore its cost performance. The price is only one of the criteria for judging the quality of power bank, not the only one.
