How to choose power bank battery

The cell is the most important part of the mobile power supply. The quality of the cell basically represents the quality of the mobile power supply product.So this is the first choice. Rechargeable lithium ion batteries have the several on the market. Polymer batteries, batteries, aluminum shell, batteries, steel shell cylindrical metal case batteries (the most commonly used is 18650 cylindrical batteries).

Aluminum batteries are mainly used for mobile phone batteries.Bbatteries steel shell is too low-level basic need not, is mainly used as mobile power polymer batteries and cylindrical batteries, relatively speaking. Cylindrical cell price cost is lower, but the performance of polymer cell will be better, capacity and discharge platform and cycle times are better than cylindrical type, the most important is that the safety of polymer cell is significantly better than cylindrical cell, polymer cell is aluminum plastic film shell, no matter what the case will not explode, The cylindrical cell is a metal shell once abnormal charging and discharging may explode, causing physical injury to the user. Like exploding cell phone batteries, there is no way to prevent it, only to reduce the probability of it happening.

Therefore, the best choice of mobile power supply polymer cell. There is no need to take a mobile power supply to risk the explosion.

Large-shared charging station market

The leasing business of shared charging banks currently accounts for about 97.2 percent of the total transaction size, followed by advertising revenue.

How should I operate abroad? What steps are required for the development of an overseas shared power bank brand?

It need three steps required for the development of an overseas shared power bank brand.

The overseas market needs to use a separate server. Therefore, we need the corresponding server protocol to ensure the normal operation and data management of the foreign shared power bank OEM brand.

In China, there are three major operators: China Mobile, China Unicom, and China Telecom, while in foreign countries. The management of shared charging treasures requires the use of foreign communication networks. Therefore, if you need brand customization, you need to provide foreign communication operators first.

In China, there are three main ways to share the power bank. Among them, WeChat and Alipay scan the code to jump to the applet to rent the shared power bank without deposit. Another way is to download the shared power bank APP and then pay the deposit and operation in the APP. In many foreign countries. The people do not used WeChat and Alipay. And there are some social software and payment methods abroad. So that users can scan the code to pay for use.

Overseas Shared Power Bank System Solution Development

The shared charging treasure system is divided into: the total back-end . the agent end. the user front-end

1.Overseas shared charging treasure terminal: The physical part of the entire system is also the part we can see. There is a QR code on the cabinet, each product is different, the size. Whether it is touch screen, the type of power bank and so on. The terminal divided into a mechanical part and an electronic control part. The electronic control part controls the mechanical part through software programming control and is responsible for the storage. Rental and return of the power bank.

2.WeChat public account or Alipay service account or APP client: This is the client for users to operate. Usually WeChat public account, Alipay service account, overseas markets are mainly APP. Although the functions are similar, mainly charging treasure Borrowing and returning process, fee payment, deposit payment and withdrawal.

3.Cloud server: It is the central control of the entire system, Because it connecting all other parts to realize the corresponding business process.

4.Merchant management background: Usually, the charging treasure rental cabinet will develop agents. The agent needs to understand the operation of the cabinet. Through the management background, you can view the relevant operation data, charging conditions, etc.

5.System management background: The management background can view the operation status and usage data of all charging treasure rental cabinets, Because can manage its merchants to manage the operation of the entire product.

How does the power bank enter the store

The first: free delivery
Get in touch with the local shared power bank brand through official website. Or contact the operation headquarters of the shared power bank brand to inform the merchant type, address, phone number, contact person and other information to apply for placement. Different merchant types can get different share ratios, generally between 30% and 50%. Merchants in this cooperation model do not need to pay any fees, but merchants have only one withdrawal entrance and no management authority.

The second: self-purchased equipment
In the early stage, many merchants used the operator to put in the equipment. But saw the income still considerable. And there was no after-sales problem. So they would buy the machine and do it by themselves, so that they could get all the income. The advantage of being an agent by yourself is that you have an independent management background, you can set the charging standard independently, and you can view the income data in real time. Generally, the cost can be recovered in one to two months. Of course, it will also be related to the type of merchant and the flow of people.

How to buy a power bank

Firstly, Battery. (Soft pack lithium batteries and 18650 )

Soft pack lithium batteries. Also known as a polymer cell. It is a paste-like battery that can be manufacture in a variety of shapes. The appearance of soft package on the market is more beautiful and rich in personality. Safety factor is higher, but go up the probability of bag, combustion is a bit bigger relatively.

18650.liquid lithium battery, 18 and 65 refers to the size of the cell, 0 refers to its cylindrical shape. Large capacity, up to 3000mAh but may explode, low safety factor. If the protective outer packing plate is attached, the probability of explosion will be greatly reduced.

Secondly, Protection plate.

The guard plate is design to automatically adjust when the power supply is overcharging or discharging. The charging function is automatically turne off after the battery is fully charged. The guard also improves the conversion rate and reduces the impact of resistance on charging.

Third, appearance.

I believe that the appearance is one of the primary factors when many friends buy mobile power supply. A stylish look can add a lot of fun. The higher the capacity in the same volume. The compact shape can highlight the portability of mobile power supply increase practicality.

Fourth, electrical parameters.

• Charging voltage and current: charging voltage generally requires 5V. Universal mobile phone adapter. The theory of charging current is that the bigger the better, the faster the charge. Pay attention to fever

• Cell capacity: general cell capacity is proportional to the volume. The larger the volume, the larger the capacity. Try to choose products with large capacity under the same volume.

• Output voltage, output current: the output voltage must require 5V. The discharging current theory is also to be the larger the better, the faster the charge. Be aware of heat issues and characteristics of digital products.

Development prospect of overseas shared charging bank

The functions of other mobile digital devices such as large-screen smartphones, tablets and digital cameras are increasingly diversified. It is also used more and more frequently, especially during business activities or outings. These terminals are at peak hours and consume power very quickly. In order to extend the use time of mobile devices, give full play to the maximum role of mobile devices. DuDucharge has developed an overseas shared charge bank. Which is suitable for scenic spots, KTV/ bars, shopping malls, cinemas, cafes and other areas. You can borrow the shared charge bank from any street in the business circle. You can use it by scanning the code of the APP, and you can return it at any time, which is simple and convenient.

As for the charging bank purchased by themselves, First of all, few people can guarantee whether the power of the charging bank is enough when they go out. Secondly, carrying a power bank will add a certain amount of weight. However, some people do not have the habit of carrying bags, and bringing their own power bank becomes a liability. This shows the convenience brought by shared charging bank. In the sharing economy, the emergence of overseas shared charging banks is inevitable. With the quickening pace of life, the sharing of charging bank makes people’s life more convenient and has a broader prospect.
