Why does the power adapter of the Xiaomi Smart Projector L1 Pro get hot when in use?

Several factors will affect the power adapter of the Xiaomi Smart Projector L1 Pro to get hot when in use, such as power supply issues, and hardware damage.
If the power adapter of the projector gets hot when in use, please refer to the following details:
During the use of the power adapter, it will generate heat, which is a normal phenomenon. The main reason is that the power adapter needs to convert the mains electricity into the current and voltage required by the projector. During the conversion process, a large amount of heat is emitted, so the adapter will be relatively hot while in operation. However, you can rest assured that the materials of the adapter are all made of fire-resistant and high-temperature-resistant plastics, so there is no need to worry about fire safety issues. But during use, please do not place any items around the heat sink to avoid poor heat dissipation.
If the above method cannot solve the problem, please apply for the after-sales inspection.
