Portable external batteries have very tightly entered the life of a modern person who does not hesitate to use the digital achievements of civilization. Smartphones, tablets and other "smart" electronics are now capable of a very wide range of tasks, but one problem has still not been resolved. And it consists in the autonomy of the device, that is, the time of its operation without connecting to the electric network. After all, without power, the gadget automatically turns into a brick, no longer capable of anything. Portable chargers were able to solve this problem . Indeed, thanks to them, you can now put in your bag a battery pack weighing only 100 grams and not worry about how much the regular battery will last in a smartphone. Moreover, now manufacturers of "smart" gadgets focus not so much on the size of the battery in the device, but on the ability to quickly charge, which also positively affects the industry and the comfort of each individual person.
Who makes batteries for batteries
Batteries for modern electronic equipment are getting cheaper every year, which has contributed to the growth of the range of external batteries in the world market. There are not so many major manufacturers of high-quality lithium-ion batteries in the world today. Giants such as LG, Samsung and Panasonic belong to these companies. But their prices for the retail consumer are often very high. Therefore, other technology market players began to produce their products at lower prices in order to gain a competitive advantage. For example, Xiaomi, whose external battery is now very popular.
What does a battery consist of?
Xiaomi's external battery is built using lithium-ion cells based on batteries from the Japanese company Panasonic and South Korean LG.
This technology is today the most advanced achievement in the field of energy storage. Therefore, Xiaomi, creating its own external battery for smartphones and tablets, used it. Lithium-ion compounds allow you to recharge the battery for thousands of cycles without compromising battery capacity or, more correctly, within the accuracy of the measurement accuracy.
An external battery for smartphones is also called a power bank. Xiaomi, creating its first “power bank”, made it powerful enough to allow it to charge the modern flagship smartphone 100% three times. Therefore, the external battery Xiaomi Mi Power Bank has a nominal capacity of ten thousand milliamps * hours.
Continuing to gain experience and improve technology, Xiaomi made its external battery 21.4% faster in terms of charging speed, and also increased the density of power cells by as much as thirty percent. This solution allowed us to achieve the dimensions of a "business card" in area, but the thickness is twenty-two millimeters, like some smartphones of the first generation.
Battery Form Factor
The Xiaomi Power Bank external battery is made in an anodized aluminum shell in the role of a housing using the latest Apple housing technology.
The design has one input for charging and one output for transferring energy to daughter devices. Four LED mini-bulbs are responsible for displaying the battery level. The more light bulbs that are lit, the more charge the Xiaomi Mi Power Bank external battery now stores.
Device security
Xiaomi external battery has several levels of protection against various external factors. Battery cells can easily cope with overcharging or deep discharge of the battery. Mi Power Bank is able to withstand strong temperature stress, as well as short circuit and a number of other factors. In addition, the battery is always in standby mode, which allows you to use it at any convenient time.
The battery is highly productive - the conversion coefficient is more than 93%.
How to use the device
For comfortable work with the universal battery pack from the Xiaomi company, the first thing you need to do is charge it to full, while avoiding overcharging. Yes, the device has protection against deep discharge and excessive charge, but it’s better not to allow such situations.
To power another gadget from Mi Power Bank, simply connect it via a USB cable, or use the adapter to the standardized connector you need. This could be, for example, a lightning cable designed for use with latest-generation Apple devices.
The battery pack is a monolithic device, and it is quite convenient to carry it in a backpack or purse to use immediately when charging is necessary. Do not allow moisture to enter the battery unit. You should also avoid dirt and loose substances like sand, because they can ruin the contacts of the device. Stick to these simple operating rules and your Mi Power Bank will last you a very long time.
