Nowadays, with more and more electronic products, charging is an unavoidable problem. What kind of charging habits do you have? Are there many people who use their phones while charging? Do many people keep the charger plugged into the socket without unplugging it? I believe many people has these bad charging habit. We need to know the dangers of unplugging the charger and safe charging knowledge.
the dangers of unplugging the charger
(1) Security risks
The behavior of not charging but not unplugging will not only consume power and cause waste, but also have many safety hazards, such as fire, explosion, accidental electric shock, etc. may occur. If the charger (especially the low-quality charger) is always plugged into the socket, the charger itself will heat up. At this time, if the environment is humid, hot, closed…it is easy to cause the spontaneous combustion of the electrical appliance.
(2) Shorten charger life
Since the charger is composed of electronic components, if the charger is plugged into the socket for a long time, it is easy to cause heat, aging of components, and even short circuit, which greatly shortens the service life of the charger.
(3) Power consumption
After scientific testing, the charger will generate current even when there is no load on it. The charger is a transformer and ballast device, and it will always work as long as it is connected to electricity. As long as the charger is not unplugged, the coil will always have current flowing through it and will continue to work, which will undoubtedly consume power.
2. Tips for safe charging
(1) Don’t charge near any other flammable things
The charger itself generates a large amount of heat when charging the device, and objects such as mattresses and sofa cushions are good thermal insulation materials, so that the heat of the charger cannot be dissipated in time, and spontaneous combustion occurs under accumulation. Many mobile phones now support fast charging of tens of watts or even hundreds of watts, and the charger heats up very quickly. So remember to put the charger and charging equipment in an open and ventilated place when charging.
(1) Don’t always charge after the battery is depleted
Smartphones now use lithium-ion polymer batteries, which have no memory effect, and there is no problem with charging between 20% and 80%. On the contrary, when the power of the mobile phone is exhausted, it may cause insufficient activity of the lithium element inside the battery, resulting in a decrease in the battery life. Moreover, when the voltage inside and outside the battery changes drastically, it may also cause the internal positive and negative diaphragms to be broken down, causing a short circuit or even spontaneous combustion.
(3) Don’t charge multiple devices with one charger
Nowadays, many third-party chargers adopt a multi-port design, which can charge 3 or more electronic products at the same time, which is very convenient to use. However, the more devices that are charged, the greater the power of the charger, the higher the heat generated, and the greater the risk. So unless necessary, it is best not to use one charger to charge multiple devices at the same time.
