AC DC power adaptor manufacturers adapters have found that when using smart devices, the hottest place is not the smart device itself, but the power adapter. There is a malfunction such as smoke.
AC DC power adaptor manufacturersAC DC power adaptor manufacturers said that because the power adapter is a switching power supply working under high voltage and high current, the workload is relatively heavy, and it is a fully enclosed structure. There are no cooling holes on the outer shell, and there is no fan inside to assist heat dissipation, so the internal temperature of the power adapter is very high when it is working.

AC DC power adaptor manufacturers recommend placing the power adapter in a place that is not exposed to direct sunlight and ventilated; do not place the power adapter near the cooling air outlet of the notebook, otherwise not only the heat of the power adapter will not be dissipated, but also some heat will be absorbed.
AC DC power adaptor manufacturers remind you not to use low-current power supplies instead of high-current power supplies. For example, the standard power adapter of a laptop is 24V5A, then the 24V7.5A power adapter can be used instead of the 24V5A power adapter, but not vice versa. Otherwise, the power supply will be damaged.
