Problems solved by technology

As people become more and more dependent on the benefits of these portable electronic devices, it is very important to enable users to use these devices at any time, but the existing chargers for these electronic devices need to be wired. To connect with these electronic devices to be charged, on the one hand, when carrying the charger of the electronic device, the entanglement of the extended wire of the charger brings troubles to people, on the other hand, when charging, the wired connection is also very inconvenient
[0003] Now there is a wireless charger that uses electromagnetic charging technology, but electromagnetic waves are divergent and are more likely to be interfered. Lasers are unidirectional and less susceptible to interference, so they are more conducive to energy concentration; in addition, electromagnetic waves are divergent , its radiation range is larger than that of laser
[0004] The existing chargers have the following disadvantages: 1. The chargers of most electronic devices are wired, and the chargers and electronic devices must be connected by extension wires; 2. The wireless charging method using electromagnetic waves is easily interfered, and Its charging radiation is larger than that of laser
