How to choose a high quality charging treasure

Charging treasure has become one of the necessary mobile phone accessories for travel. As an important companion for mobile phones, it is naturally more cautious when purchasing. However, the charging of the market is full of treasures. How do you choose to choose a good quality charging treasure?
First point: look at the battery
As the core part of the charging treasure, the battery is the key component that determines the quality of the charging treasure.
Currently, there are two types of batteries in the market, lithium-ion batteries and lithium polymer batteries. The biggest difference between the two is that the electrolyte used is different. Lithium-ion batteries use liquid electrolytes, while lithium polymer batteries use solid polymer electrolytes. Therefore, lithium chloride batteries will not be damaged if they are damaged. In the case of liquid leakage, the safety is relatively high.

In addition, lithium polymer batteries have higher energy density than lithium ion batteries, and lithium polymer batteries use solid polymer dielectrics, which are more plastic in shape. These advantages can be combined to foresee the future. Lithium polymer batteries will be the mainstream batteries used in charging treasures.
In the choice of lithium polymer batteries, the choice of certification by the authority can also be more secure in terms of safety. Green's pebbles charging treasure is based on the US UL-certified GPC original polymer lithium battery. The UL Safety Test Institute is the most authoritative in the United States and the largest private organization in the world for safety testing and appraisal. The products certified by it are products with a fairly high level of safety in the market.
Of course, the lithium-ion battery currently circulating in the market is quite mature and safe.
Second point: look at circuit safety protection
In addition to the battery cells, the protection mechanism of the charging treasure is also very important. A good charging treasure must have multiple protection mechanisms such as overcharge, overcurrent, over discharge, short circuit, overvoltage, over temperature, etc. to ensure that it is encountered. When the current is too large, the voltage is too high, sudden short circuit or sudden high temperature and other unexpected situations, the charging treasure can instantly protect itself and protect the mobile devices such as mobile phones that are being charged.
he more comprehensive the protection mechanism, the safer it is. At present, the good charging treasures on the market basically have 7-fold protection such as overcharge protection, overcurrent protection, overdischarge protection, short circuit protection, overvoltage protection, overpower protection, and temperature protection. Of course, there will be a more comprehensive protection mechanism for charging treasures. Green's charging treasure also has recovery protection. It will automatically restore the output after the short-circuit fault is removed. In addition, there is electromagnetic field protection to prevent the external magnetic field from affecting the normal operation of the charging treasure.
The third point: look at the body parameter identification
Whether there is a perfect parameter identification on the charging treasure body determines whether the charging treasure is convenient to carry out. Now the Civil Aviation Authority has stipulated that there is no charging treasure, that is, the charging treasure that does not clearly indicate the specific manufacturer, rated capacity, input and output voltage on the fuselage, and it is forbidden to bring the aircraft.

Phone charger stability and convenience

When we buy goods, most of them will consider what brand, quality, price and so on. In fact, the purchase of the phone charger is the same, everyone will carefully consider what brand, stability, convenience, etc. before the purchase, but after use, all the shortcomings will be ignored, just use it, unless it is really not used Will only consider changing. The following Jin Xinyu power supply will discuss the convenience and stability of the phone charger. stability Phone chargers are mostly in the same stability, based on the performance of overcurrent protection, EMI radiation, voltage deviation, ripple suppression, cross load, timing, dynamic testing, etc., to determine whether the phone charger can be stable for a long time. run.   Depending on the environment, the data will behave differently and the stability will not be the same. For example, our domestic mains voltage is 220V, and the mains voltages such as Japan, the United States, and Canada are 110V. The stab...

The difference between the original and the copy of the iPhone charger

There are a lot of people using the iPhone now, so the high-copy charger is also very popular. Of course, many users still use the original charger. I don’t know if you have the same feeling as me. Those chargers are just like our salary, and they always disappear inexplicably. Cheap chargers don’t dare to buy, so that you won’t buy inferior or high-copy chargers, today Yuda original iPhone charger wholesale  will share with you how to distinguish the charger knowledge. 1. First look at the outside, in fact, the careful person can immediately feel which one is the charger of the copy, the overall craftsmanship is still very easy to compare. Non-original chargers have a green dot. Merchants often say that Green Point is one of the genuine and security logos, and green dots are genuine. This is not the case. In fact, most of the high-copy chargers have green dots, but the same is a poor quality chip. Don’t be deceived by the seller. 2. Pay attention to the text of the charge...

7 bad habits that damage cell phone battery life

图片
1, overnight charging Play the phone before going to sleep at night, then plug in the power to charge, get up in the morning to disconnect the power, this is the charging habit of many users. Although the mobile phone circuit has a protection mechanism, the application APP in the mobile phone consumes power at any time, and the power consumption is recharged, and the entire communication is repeated. The loss of the mobile phone battery is related to the number of times of charging, which will affect the life of the battery. It is best to turn off the phone, or turn off all apps to charge. 2, frequent charging As the author said at the beginning, charging anywhere and anytime has become a habit of mobile phone users, but frequent charging and plugging of data lines, for some smart phones with port modules for independent boards is damaged, long-term Use will damage the cell phone battery . 3, exhausted power is charging In order to reduce the number o...
