Every summer, many cities experience power supply shortages, and some rural areas even experience indirect power outages. Saving electricity has become a general consensus in society, but sometimes we waste power unconsciously. According to the survey, most people keep the charger plugged into the power strip for the convenience of charging and do not unplug it after charging. But the charger manufacturer wants to tell you that connecting the charger to the plug board will consume power even if it is not charging.

When the charger is in no-load state, there will still be current flowing through the charger, and the charger's control circuit will also be in working condition, which will consume some power. The power consumption of a general charger in the no-load state is about 150 milliwatts, and inferior chargers will be higher. Although the power consumption is insignificant, if everyone charging does this, it will be a huge loss.

In addition, if the charger is plugged into the plug-in board for a long time and is not unplugged, it will not only waste power, but also accelerate the aging of the charger, shorten the service life of the charger, and also pose certain safety risks. There were previous news reports that a Mr. Wang in Chongqing used a poor-quality charger and left it plugged into the power strip for a long time. As a result, the charger spontaneously ignited under no-load conditions and caused a small fire. Some property damage was caused.

Therefore, charger manufacturers hope that everyone can develop the habit of unplugging the charger after charging. Current charger manufacturers are also working hard to improve the energy efficiency of power supply products and reduce the no-load power consumption of chargers. Let us work together to save energy and protect the environment.
