With the increasing number of intelligent devices in modern society, a safe, reliable and beautiful mobile power supply has become inseparable from our life. Whether it is for travel or daily study, the mobile power supply in your pocket can be seen everywhere, almost every person has one as a spare part of electronic devices. Xiaomi Mobile Power has conquered many users because of its exquisite workmanship, unique aluminum alloy metal shell and cheap price. After experiencing 5200mAh, 10400mAh and 16000mAh colorful metal shell mobile power, on November 25 last year, Lin Bin, partner of Xiaomi Company, "flattened" Xiaomi 16000mAh power supply with a pan, 5000mAh ultra-thin portable polymer mobile power supply was born, and this mobile power supply has been introduced with objective sales and continuous praise. Xiaobian currently owns 5200mAh, 10400mAh, 5000mAh mobile power supply and some other brands of mobile power supply, but my favorite is Xiaomi Ultra thin 5000mAh mobile power supply. Because it is thin, it can be carried around, which is very suitable for girls. I hope I can add new members to my power supply family when the opportunity arises

This is our product manual. Open the manual and see the relevant information, use method and three guarantee certificate about Xiaomi Mobile Power. The most thoughtful thing is to add a method to verify the authenticity of Xiaomi Mobile Power on the last page. Who makes Xiaomi so hot? There are often vendors selling fake Xiaomi mobile power supplies on the roadside.

The 10cm data cable is really short. I hope it can be lengthened, but it is suitable for daily portable use. A good data cable can not only guarantee the charging speed, but also reduce the power consumption. As for the selection of mobile power and data lines, different data lines, due to differences in internal resistance and other aspects, will lead to some differences in the charging voltage. If the charging voltage is higher than the bearing capacity of the phone, the phone will be damaged, serious or even completely unusable. Therefore, a good data cable is very important for mobile power and mobile phones.

This is our protagonist - 5000mAh mobile power main body, silver aluminum alloy metal shell, the front is the mi logo, there is nothing else, and the back is the website of Xiaomi.com. The simple and generous design can be regarded as an aesthetic feeling.

At the bottom of the 5000mAh mobile power supply is the product information and certification information: power supply model, input and output voltage and current, production and manufacturer, warning signs and large power capacity.

There is a sticker at the end of the key and the output port, which proves that it has not been used for unsealing. Tear it off After the sealing strip, from left to right are: power check key, 4 LED power indicators, Micro USB interface, USB-A interface. Due to the flattening of the shell, the power key has changed from the original 5200mAh, 10400mAh, 16000mAh circle to the current ellipse, and the power charging port and output port have also changed from the original top and bottom rows to the current left and right rows. Hidden keys, although invisible, can be found with a touch.
