The speed comparison of the four magnetic charging banks is as follows:
The first Anker is really good, the charging speed is the fastest, the capacitance, adsorption capacity, and appearance design are good, and the disadvantages are expensive. The second Bex charging speed is good. The third product sheng, the charging capacity is the smallest, the adsorption force is very strong, the size is small, the charging speed is also OK. The fourth has the most unique appearance, has the power display, the charging capacity is not high, and the charging is relatively slow.
The charging speed of Apple's original 15W MagSafe magnetic wireless charger was tested as a comparison: under the same environment (screen charging, room temperature 24℃, no additional heat dissipation), Apple's original 15W magnetic wireless charger charged 12mini in 30 minutes: 32%
