First of all, the balance of price and performance is a highlight of the millet wireless charger. The 20W wireless charger purchased at the price of 99 yuan, its appearance design, charging efficiency and texture quality can make people feel excellent value for money. The product's dual coil design, whether vertical or horizontal, enables stable and efficient charging to meet the needs of different use cases.
Simple all-black body design, matte texture of the surface, with round base non-slip design, noJust beautiful, but also quite stable when used. In terms of charging performance, whether it is with 40W fast charging head, or in the case of horizontal or vertical placement or with a shell, it can quickly identify and start fast charging, and the efficiency is close to wired charging.
The only pity is that on wireless charging, the charging efficiency of 5v1a is still a little low. Finally, in terms of my personal experience, this wireless charging bank has a good performance in daily charging, portability, and appearance level. At this price point of more than 100, it is still considerable.
After placing the phone, the charger can immediately recognize and start working, and the LED light is on. Tests of different phone cases show that cloud sense phone cases are thicker but more efficient at charging. In IOS14, it takes about 45 minutes to fully charge, after rising to IOS11, the time is extended to 50-55 minutes, which may be a system problem, looking forward to the subsequent update
Magnetic wireless charging is more convenient, direct, gently close to magnetic charging; Wired charging is faster and can achieve PD fast charging, but it is relatively not so convenient. The Apple iPhone8 began to support wireless charging, and the iPhone12 was upgraded to MagSafe magnetic charging.
iPhone general meA cable is required, and the device can be charged by simply placing it on the charging dock. The disadvantage is that the charging speed is slow, the charging efficiency is also low, and the device needs to be placed on the charging base, which is not flexible enough.
2, low efficiency. At present, wireless charging technology is not mature, many problems have not been solved, and the efficiency of energy storage and transmission is less than that of wired charging; Charging speed is slow. Due to low efficiency, the charging speed is slow under the same input power; The cost is high. Wireless charging has high technical content, consumes more manpower and material resources, and the corresponding manufacturing cost is also relatively high; Low compatibility.
3, wireless fast charge noIt's gonna be fast, not slow. Wireless fast charge is much faster than wireless fast charge, and slower than wired fast charge. The power that the charging head wired outputs to the wireless fast charge base is not the wireless fast charge output power but the wireless fast charge input power. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.
4. Despite significant advances in wireless charging technology, some challenges remain. First of all, its efficiency is slightly inferior to the wired charging method, and the charging speedIt's relatively slow. In addition, the performance of wireless chargers is affected by environmental factors, such as electromagnetic interference and signal interference, which can reduce charging efficiency. In addition, for many consumers, the high price of wireless chargers has become a major consideration for purchase.
5, modern wireless chargers usually have fast charging function, and its charging efficiency is not inferior compared with wired charging. At the same time, wireless chargers can also adapt to different equipment needs to meet the charging needs of a variety of devices. This can be very beneficial for multi-device users.
