Note！The mobile phone power bank is safe to use in this way

When you are away from home, a charging treasure is essential.

So do you know how to use and purchase a power bank correctly?

Follow the editor to learn the following knowledge, so that you can be safe and secure!

1. How to use the power bank correctly

Avoid heavy pressure and violent vibration, be gentle with the charging treasure, and do not violently press or shake, so as not to cause internal short circuit and other problems.

Avoid high temperature, away from heat sources, try to avoid charging in overheated environments, do not contact heat sources such as fire sources, and do not use and store in overheated and humid environments.

Do not charge for a long time, long charging may cause the power bank to overheat. If the product quality is not good, it may also cause an explosion, and if it is found that it is abnormal, it will decisively stop using. If it is found that the charging treasure has overheating, abnormal noise, deformation, bulging and other abnormal situations during use, you should decisively stop using it, choose to buy regular products, so as not to buy fake and shoddy products, and regularly carry out performance maintenance.

If the charging treasure is not used for a long time, it should be charged and discharged every once in a while to maintain its normal performance, try to use the original plug, and use the original plug to charge the charging treasure as much as possible. In the absence of the original plug, you should buy a plug consistent with the parameters of the charging treasure, do not disassemble and transform the charging treasure privately, the battery contains harmful ingredients to the human body. The disassembly process can cause discomfort to the body and may even damage the eyes. In addition, the electrolyte of the lithium battery will quickly separate the heat when it encounters a large amount of water, thereby causing an explosion.

2. How to choose a power bank?

First, pay attention to the appearance, regular manufacturers' product packaging, there will be manufacturer production address, telephone, anti-counterfeiting code and other information

When purchasing, you can carefully check the authenticity and other information

Second, to determine the capacity, not the larger the capacity, the better, there are some inferior products with large capacity, but the technical level is far from reaching

More prone to quality issues. If it is only to prevent the mobile phone from running out of battery, choose a medium-capacity, compact product. Under normal circumstances, a 5000 mAh power bank can meet the daily use of a smart phone.

Third, to see the conversion rate, the actual charging conversion rate of the charging treasure, generally between 65%-85%, the lower the conversion rate, the greater the loss, the greater the loss, the greater the heat generation, there may be potential safety hazards.

Note!

If the power bank appears discolored, deformed, leaking, easy to get hot, etc., stop using it immediately!

The corrosiveness and flammability of the electrolyte have great safety risks, so you must be careful when using a charging treasure

Third, why does it take so long to charge with a power bank?

Some friends reported that charging with a power bank is more time-consuming, why is this?

The charging treasure is to use the USB interface to charge the mobile phone, compared with the alternating current of the charger, the output of the current is small, and the cable of some charging treasures is too thin or the resistance of the cable is too large, which will also lead to a decrease in charging speed.

In addition, the quality of the power bank's own cells is too poor, in order to stabilize the current to control the output, it will also lead to longer charging time.
