[0025] Since Palm launched the Palm Pre, the first mobile phone to support wireless charging technology, in 2009, wireless charging technology has undergone development, but it still faces many challenges on the road to popularization.

[0026] On the one hand, wireless charging speeds are unsatisfactory, lagging significantly behind wired charging and failing to meet users' demands for fast charging. On the other hand, heat generation is particularly prominent when charging devices (such as power banks) or charging docks charge mobile phones and other devices, affecting not only the lifespan of the devices but also potentially posing safety hazards. To alleviate this problem, charging power is typically reduced, but this further exacerbates the slow charging speed. Furthermore, the high production costs of wireless charging technology lead to expensive products, undoubtedly increasing the barrier to entry for consumers and reducing market acceptance. In summary, these factors collectively constrain the large-scale application of wireless charging technology.

[0027] Therefore, this application proposes a charging base, charging and discharging device, and charging device based on the contact principle, which can solve the problems of slow charging speed, short service life, and high production cost in the prior art.
