Unknown details in power bank

More and more people can’t live without the convenience of digital technology such as mobile phones and tablet computers. Most digital devices rely on electricity as their driving force. Therefore, many people need to use charging treasures to give them a variety of digital devices. The devices add power to increase their battery life. Charging treasure industry has been hot for several years, can be described as strong and powerful, many brands have also grown up in the minds of consumers, "fighting brand", "well-known in the industry", everyone does not know, in fact, we do not really understand this product .power bank plant

Let's take a brief look at the details of the unknown design, functionality, and quality of ChargePad today.

Usually, everyone understands the quality of charging treasures are stuck in the obvious aspects of the shell material, circuit board workmanship and cell quality. It is not too much to understand some of the potential quality details of the product.

Because the market is becoming more mature, consumers' demands for charging treasures are also increasing. Therefore, manufacturers have different emphasis on product design and functional differentiation. Some products are rich in software function design, such as intelligent identification and intelligence. Matching output, smart protection, etc.; some products are more inclined to improve the hardware, such as making the product more user-friendly, improving component quality and workmanship, etc., which we can all call latent quality details, and they affect in all aspects. The user's comfort level.

There are many charging treasures on the market with dual USB output interfaces, but users will find many problems during use. For example, they cannot charge two devices at the same time. The maximum output parameters and so on.

When choosing the dual USB output interface, we must be clear about the following two questions: 1. Is the nominal output parameter the single interface output or the sum of the two interfaces? 2. What is the maximum output parameter that can be achieved when two ports are used at the same time?

Let's take the above diagram as an example. It has two standard USB output interfaces. The interfaces are marked with the maximum output parameters they can provide: Blue USB supports up to 5V/2.4A output, and black USB supports up to 5V/1A output. Then the problem comes: When we use the blue interface, can the black interface be used? 2. What are the maximum output parameters that can be reached when using both interfaces to charge the device at the same time?

If we are using the blue interface, the black interface can be used normally, it is proved that it can simultaneously supply a 5V/2.4A input parameter device and an input parameter 5V/1A device power;

If we use the blue interface, the black interface can not be used, then prove that the total output parameter of the two interfaces is 5V/2.4A, we can use it to charge the 5V/2.4A input device separately, and also can give two The device with the input parameter of 5V/1A is charged.

The necessity of output parameters is clearly defined: 1. It is safer to use the parameters that match the equipment being charged, to avoid charging the device. 2. The dual-interface charging Possibly requires intelligent distribution of output modes. Suppose a charging treasure charges two devices at the same time. If there is no intelligent allocation, it may result in insufficient output for both devices. The intelligent distribution output is designed to ensure the input power required for high-priority products. Allow users to urgently need the fastest charging speed;

The hazard of output parameters is not clear: Some manufacturers deliberately do not standardize the output parameters on the output interface, and play a word game when they are publicized. As a result, users cannot use the products normally after they buy the products or the charging speed is too slow, causing unnecessary losses; The protective function of the charged device is not perfect, and the user mistakenly uses a large current to charge the low-current device, easily causing over-current and causing damage to the device.
