With the rise of the mobile game and the hot broadcast of the web drama, we will give the mobile phone every day, which causes electricity to drop down, and the frequency of dealing with the charger is also significantly added. At this point, you must pay attention to the following problems. The order in which the charging is in theory, the formal charger does not have to consider this problem.
However, considering that the charger is inserted into the power outlet, there will be impact current, if the power socket or charger itself has quality hidden dangers, there is a small chance to cause harm to the connected mobile phone. So, it is recommended that you choose the second charging order. In addition, the early smartphone has also appeared a similar bug, that is, connect the data cable and mobile phone, then connect the charger and power outlet, and finally connect the data cable and charger.
This extreme case may make the mobile phone error read information of the USB interface + D-D line, causing the mobile phone to identify the current USB connection mode, can only input at a current of 0.5A. The station of charger believes that many children's shoes have the same question: When the mobile phone is not charged, the charger remains in the power outlet when the mobile phone is not charged.
Is it not charged? Anyway, the habit of Xiaobian is that the charger always stationed in the power outlet, never separated. So, this habit is not worth advocating? The answer is naturally negative and does not advocate. The charger is left on the power outlet for a long time.
As long as the charger is genuine, there is no security hazard in theory. However, the mobile phone charger is inserted on the power outlet, and there is a series of processes such as step-down, rectification, filtering, even if the data line is not loaded (no mobile phone), there is also a certain no-load loss. There have been netizens to test the no-load loss of different models of mobile phone charger.
The result is a situation in two days of ice and fire: the lowest no-load power consumption of mobile phone charger is only 0.004W, and there is almost no power consumption, and no power consumption The highest is up to 1W! This figure comes from the network in other words, the size of the phone charger is depends on its own quality, and the average power consumption of brand chargers can be controlled within 0.1W, and some cottage or quality is worrying.
Charger, its power consumption can break through the horizon. Taking the charger of the no-load power of 1W as an example, its 1 year consumption can reach 8.76 degrees, calculated according to the 1 degree of electricity, and the electricity bill is about 4.
38 yuan in 1 year. In other words, the average no-load power consumption of the mobile phone charger (calculated according to 0.1 W) is about 0.
438 yuan. Lopeful? But please don't forget that the charger of each family member mobile phone may consume a power outlet. Moreover, my country's today's total population is huge, and each person is equivalent to the loss of 0.
438 yuan a year. As an individual, if each of us can develop the habit of the mobile phone charger (or turn off the power supply of the socket) when it is not charged, it can have a long-term public welfare effect similar to the earth. The compatibility of the charger is as specified.
If the family has accumulated several or even dozens of mobile phone chargers for a long time, do you have to find the original charger before charging your mobile phone? If the charger is mixed without danger? This is a topic of the old man, and the small branch will reiterate again: as long as it is a regular manufacturer, the mobile phone, the tablet, portable / Bluetooth speaker, as long as the charger supports the 5V standard output voltage, then They are compatible with each other and can charge smartphones. The reason is very simple, the voltage and current size of the mobile phone charger can depend on the ability of the mobile phone internal charging circuit and battery to current. There is a sound protection circuit inside the charger.
Once the output current is too large, the protection circuit can suspend or reduce the current output to prevent danger. If a mobile phone only supports a power input of 5V / 2A, you give it a charger of 5V / 4A, the latter can only output at a current of 2A; if the mobile phone supports 5V / 4A power input, 5V / 1A's charger can also charge it, but only the current of 1A can only output 1A, and the efficiency is reduced by 75%. In other words, the mobile phone charger of different brand models can be compatible with each other, just unreasonable matching will affect the charging time of the phone.
In addition to Qualcomm QC and Lianfa PE belong to a universal fast charge method, other fast charge techniques (such as VOOC, SFPC) are only suitable for their own brands. For example, you use the Oppovooc flash charger to charge the millet phone, the latter can only charge the standard 5V / 2A standard, and vice versa. In addition, we still need to prevent small Niu La cars, such as Take 5V / 0.
5A or 5V / 1A charger to charge the latest mobile phone. Since the new mobile phone supports fast charge, the charging process will trigger the charger for a long time to run in its maximum output power, so that it is easy to cause the charger's own heat generation. At this time, if the charger itself is not perfect enough, long-term overheating or small probability of surge will bring a certain safety hazard.
When the mobile phones circulated on the Internet, they exploded, fire, etc., mostly caused by a third-party charger due to poor quality.
