Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging, in particular to a vehicle-mounted wireless charger. Background Art

[0002] As user needs increase, mobile terminals are used more and more frequently. Mobile terminals are portable, which greatly facilitates user use. Although the battery life of mobile terminals continues to increase, users need to charge the mobile terminals in time after the battery of the mobile terminals runs out. At present, users still need to use a power cord to connect the mobile terminal to the power source when charging the mobile terminal. This charging method requires users to carry a power cord and also requires users to connect the power cord when charging. Obviously, this is inconvenient for users to charge, which in turn affects the user's experience.
