How to choose a high-quality power bank?

As people’s demand for mobile power and mobile power continues to increase, the safety and quality of these products are getting more and more attention. In addition to using portable power supplies and charging pads to ensure correct charging and placement, the selection of high-quality products is also more intensive.

We know that the quality of the power bank is very important, because the built-in core contains more power, and its fracture will cause serious damage, so customers also want to buy high-quality products, easy to use and peace of mind, buy mobile power and Charging time.

At present, high-quality mobile power supplies will use high-quality metal shells, use polymer batteries, and cooperate with multi-channel protection planning, fully considering the safety and convenience of customers. However, due to cost reasons, this product is much more expensive than ordinary mobile power charging stations, so it is more popular in the high-end market.

How to buy high-quality mobile power and charging stations, but also pay attention to the following three aspects:

1. The power bank should have a good battery

There are two types of portable power batteries, one is the ordinary type, and the other is the ordinary type. The two media are very different in form and structure. Lithium batteries have the advantages of low price, but the disadvantages are that the system is large, heavy, and has a short service life, which may cause an explosion, which is very fatal. Polymer batteries are safe, non-explosive, and light in weight, and are used in high-end digital devices. The disadvantage is that they can be expensive.

High-quality mobile power supplies often use high-quality national standard polymer cores, which can maintain the stability and safety of the product under severe external conditions such as high temperature and knock, and fundamentally protect the safety of users.

2. The circuit board of the mobile power supply should be able to provide high conversion rate and comprehensive protection

The circuit board has several important functions. Automatically control charging and discharging to prevent battery damage. For example, when the power supply of a mobile phone is full, it will automatically shut down and charge. In fact, the protection is the same as that of a mobile phone charger.

In addition, the board has another important function, which is the conversion rate. For example, the nominal 5000mAh battery charging user’s device is not 100% fully converted. Your phone has a 1500mAh battery, which can be charged with a 5000mAh mobile power bank. In theory, it can be charged more than three times, but in practice, it may not be fully charged. This is because the battery and the charged object have resistance, which consumes part of the battery. Therefore, the circuit board plays a role in reducing internal resistance and optimizing IC circuit planning, thereby improving functions.

The better the quality of the mobile power supply, the more professional the intelligent selection circuit, which can supply more than 90% conversion rate, and output adjustment according to the characteristics of different charging equipment, in order to achieve higher energy utilization and protect the charging equipment. In actual use, whether it is over current, over voltage, overload, or accidental short circuit, the power can be cut off immediately and enter the protection state to ensure the safety of users.

3. The shell of the mobile power supply should be sturdy to fully protect the internal structure

The important purpose of the mobile power room is to protect the internal circuit, heat dissipation and beautiful planning. Nowadays cheap portable power supplies have plastic casings, and protection and cooling functions are also common. The high-end mobile power supply is made of a metal shell, which not only provides high-strength protection, but also provides better heat dissipation function, and the appearance of the handle is much better than the plastic shell.
