The drawback of smart mobile devices lies in the limitation of battery capacity and the disadvantage of large power consumption, which is plagued by users. As a result, a portable power supply has swept through, and mobile power has quickly been welcomed by consumers. As for equipment manufacturers, they have begun to develop similar products. Products, Xiaomi is undoubtedly the leader among these manufacturers, with a low price advantage and a broad product distribution line, occupying a large share of the mobile power market.
However, due to the low technicality of mobile power, mobile power technology has been widely copied, refurbished, prices have dropped, and vicious competition has intensified. Anti-products have also continuously flowed into the market, thus making mobile power quality unsecured and problems arise. Nothing to fear, such as virtual standard capacity, unable to charge, fever, fire, and even more directly explode.
Then, we need to pay special attention to the daily use of mobile power, it is necessary to popularize some knowledge.
Rated Capacity
The rated capacity is not the effective use capacity, the rated capacity is the capacity marked on the mobile power supply, and the actual capacity is the actual output capacity. Any electronic product will be depleted, and the quality of mobile power depends on the energy conversion rate of up to 80%, the average is about 70~75%, and the difference is even only 30%. If the conversion rate is lower than 75%, it means The loss of the mobile power line is large, and the heat generated by the battery itself is also large.
[Approximate conversion method of virtual standard capacity] Capacity of mobile power supply X 80% ÷ Mobile phone battery capacity = number of chargeable times (powered down charge), that is, you can judge the conversion rate of a mobile power source from the capacity and the number of charge times. quality.
Millet mobile power heating problem
When the mobile power is charged without load, it will not overheat. It may be that the input voltage is too large or the output is unstable. At this time, you can look at the output voltage of the mobile power supply and compare it with the smart mobile device. (Do not use it while charging, damage the battery, it is easy to make the mobile phone overload, it is also one of the phenomena that cause the phone or power supply to heat up, and even more causes a short circuit.)
It is normal to have a slight fever when charging. Under normal conditions, the surface temperature will not exceed 50 degrees.
Xiaomi mobile power supply adopts LG/Samsung lithium ion battery, the latest USB intelligent control chip and charge and discharge chip of Texas Instruments. This mobile power supply is protected by multiple protections such as temperature protection, short circuit protection, input overvoltage protection, input anti-reverse protection, etc. The quality is relatively guaranteed, so there is no safety accident when used under specified conditions, if you are specific In case of use, you should pay attention to the abnormal phenomenon. In addition, if it is a quality problem, you can directly call Xiaomi customer service to find out the situation.
