The power size of the magnetic charging bank needs to be selected according to the personal use needs and the power of the charging device. Generally speaking, the power of the smaller magnetic charging bank is between 5W and 10W, which is suitable for smartphones or other small electronic devices with smaller rechargeable battery capacity. The power of the larger magnetic charging bank is between 15W and 20W, which is suitable for tablets, laptops or other high-power electronic devices with large rechargeable battery capacity. In short, the power size of the magnetic charging bank should be considered according to actual needs and safety.
Magnetic charging bank 7.5W or 10W is more suitable.
At present, the wireless output power of the mainstream infinite magnetic charging bank is 5W, 7.5W, 10W and 15W. Big brands such as Xiaomi and Apple are estimated to take into account charging efficiency and heating, and their wireless charging power is generally about 7.5W and 10W, which is relatively conservative.
So when buying a magnetic charging bank, you can give priority to 7.5W or 10W.
The power selection of the magnetic charging bank needs to be determined according to individual needs and use scenarios. In general, 7.5W magnetic charging bank can meet daily charging needs, and if you need faster charging speed, you can choose 10W or 15W magnetic charging bank. However, it should be noted that with the increase of charging power, the volume and weight of the charging bank will also increase accordingly. Therefore, when choosing a magnetic charging bank, you need to make a trade-off between power, volume and weight to find the most suitable style for you.
