Attention! This is how to use mobile phone power bank safely

Are you anxious when your phone battery is low? When you go out, a power bank is essential. So, do you know how to use and buy a power bank correctly? Follow the editor to learn the following knowledge to keep you safe and at ease!

How to use a power bank correctly?

Avoid heavy pressure and severe vibration: Be gentle with the power bank and do not apply heavy pressure or vibration violently to avoid causing internal short circuits and other problems.

Avoid high temperatures and stay away from heat sources: Try to avoid charging in an overheated environment, and do not contact with heat sources such as fire. Do not use or store it in an overheated or humid environment.

Do not charge for a long time: Long-term charging may cause the power bank to overheat, and if the product quality is poor, it may also cause an explosion.

Stop using it immediately if you find any abnormality: If you find that the power bank is overheating, making unusual noises, deforming, bulging, or other abnormal conditions during use, you should stop using it immediately.

Choose to buy regular products: Don’t be tempted by cheap prices. When purchasing, choose regular or official channels to avoid buying counterfeit and shoddy products.

Perform performance maintenance regularly: If the power bank is not used for a long time, it should be charged and discharged at regular intervals to maintain its normal performance.

Try to use the original plug: Try to use the original plug to charge the power bank. If the original plug is not available, you should purchase a plug with the same parameters as the power bank.

Do not disassemble or modify the power bank without permission: the battery contains harmful ingredients to the human body, and the disassembly process will cause discomfort to the human body and may even damage the eyes. In addition, when the lithium battery electrolyte encounters a large amount of water, it will quickly decompose and release heat, causing an explosion.

How to choose a power bank?

First, you should pay attention to the appearance. The product packaging of regular manufacturers will have the manufacturer's production address, phone number, anti-counterfeiting code and other information. You can carefully check the authenticity and other information when purchasing.

The second thing to do is to determine the capacity. The larger the capacity, the better. Some inferior products have large capacity, but the technical level is far from up to par, and are more likely to have quality problems. If you just want to prevent your phone from running out of power, choose a medium-capacity, small-sized product. Generally speaking, a 5000 mAh power bank can meet the daily use of a smartphone.

The third thing to look at is the conversion rate. The actual charging conversion rate of a power bank is generally between 65% and 85%. The lower the conversion rate, the greater the loss, and the greater the loss, the greater the heat generated, which may pose a safety hazard.

If the power bank changes color, deforms, leaks, or becomes hot, stop using it immediately. The corrosiveness and flammability of the electrolyte present a great safety hazard. Be careful when using a power bank!

Why does it take so long to charge a power bank?

Some friends have reported that charging with a power bank takes a long time. Why is that? Power banks use USB ports to charge mobile phones. Compared with the AC power of chargers, the output of current is small. Some power banks have too thin wires or too large resistance, which can also reduce the charging speed. In addition, the quality of the power bank's own battery is too poor. In order to stabilize the current to control the output, it will also cause the charging time to be longer.
