Many people are curious, how does electricity "run" through their phones when they can be charged just by putting them on? This article takes you through the core principle of wireless charging - electromagnetic induction. The coil inside the charging base generates an alternating magnetic field, and the coil on the back of the phone captures the change in magnetic field and converts it back into electrical energy to charge the battery. Simply put, it's like magic, but behind it lies Faraday's law of electromagnetic induction silently
Power banks on the market are getting thinner and thinner, but will you really choose? This article teaches you to avoid pitfalls from three dimensions: first, look at "protocol compatibility", whether it supports the mainstream fast charging protocols of Apple and Android; Second, looking at the "temperature control performance", the ultra-thin body has a small heat dissipation area, and the temperature control technology directly affects charging safety and battery life; Th
The power bank is bulging, hot, and cannot be charged...... What are the potential safety hazards behind these phenomena? This article popularizes the basic working principle of lithium batteries, and lists the four major signs before the "scrapping" of power banks: shell deformation, intermittent charging, abnormal heating, and odor emanation. At the same time, users are reminded that the power bank also has a "shelf life", the general cycle life is 300-500 times, and the bu
