How about the Best power supply, what is the role of the Best power switch

Due to the advantages of online channels, they are often the most attractive to consumers to buy. And we see that the current best-selling mobile power banks have a common characteristic, that is, ultra-large capacity and extremely low**. And this has become the main factor that consumers consider when purchasing.

But in fact, the quality of such a power bank may not stand the test. Therefore, when buying, it is not advisable to blindly follow online sales, keep a rational mind, and try to choose some well-known brands, so that the probability of problems will be reduced a lot.

As mentioned earlier, too low mobile power products are not worth buying, so does it mean that the higher the quality, the better? Nowadays, the mobile power products on the market are very different, cheap dozens of yuan, expensive hundreds or even thousands of yuan. In fact, the cost of mobile power supply is not as high as we think, mainly including the cell, circuit board and shell three parts, generally speaking, the production cost of mobile power supply using 18650 battery cells is lower than that of polymer battery cells.

Taking 10000mAh as an example, the mobile power supply of 18650 cells is usually 100 to 130 yuan, and the mobile power supply of polymer cells is usually 150 to 200 yuan. Of course, some power banks with outstanding design or integrated functions are more expensive. If you add the brand effect,** will be several times higher In short, to measure the advantages and disadvantages of a mobile power supply, it is necessary to consider from several aspects such as charging performance, durability, safety, conversion efficiency, appearance, etc., ** is only one of the reference standards, can not completely determine the quality.

Best is the most reliable power bank I have ever used, the first to buy a mobile phone in the Xiaomi store by the way, used for 4 years, very stored electricity, will not automatically consume electricity, this year I bought 2 in Best ***!

I used the 20000 of the Best 0181 type, and it was useless to go on a business trip, and I rushed through the electricity twice a month, and I couldn't rush in, and the merchant ignored you.

It is used to turn on and off the power bank, the way to turn on the power bank is to press once or press the power button 2 times to turn it on, and the way to turn it off is to press and hold the power button for 3 to 5 seconds or press the power button 2 times to turn it off.

This is because the output of the power bank does not match the input of the phone.

1. When the output current of the mobile power supply is relatively small, the mobile phone may automatically disconnect the charging in order to protect the battery, at this time, the mobile power supply can not sense the current of the mobile phone, and the mobile power supply will misjudge that the mobile phone is fully charged, and it will be automatically disconnected from the charge.

2. There is also a situation that the output of the mobile power supply is relatively small, and it just consumes power when the back cover of the mobile phone is running, so it will feel like it cannot be charged.

The reasons why the power supply cannot be charged are:

1.The device that charged the power bank is broken 2The power bank itself is bad.

Workaround:1You can change the data cable or change the charger first.

2.If you can't charge the data cable or charger, you can communicate with the customer service of Best to replace it, and the quality problems will be replaced with free shipping within one year.

First of all, check whether the charger is correct.

Often. Check whether the charging data cable is correct.

Often. Check whether the charging data cable plug and the power bank input interface are normal. If the above checks are normal, then the problem may be that the charging control circuit inside the power bank is abnormal or damaged, etc.

Best power banks are not very well-known, but they do not affect the use of them.

1. Mobile power pack, English Mobile Power Pack (referred to as MPP), a portable charger that integrates power supply and charging functions, can charge or standby power for digital devices such as mobile phones anytime and anywhere.

2. Generally, lithium cells or dry batteries are used as power storage units. It is different from the battery configured inside the product, which is also called an external battery. Generally, it is equipped with a variety of power adapters, which usually have the characteristics of large capacity, multi-purpose, small size, long life, safety and reliability.

3. It can supply power or standby charging for a variety of digital products such as mobile phones, digital cameras, MP4, PDA, PDAs, PDAs, and other digital products anytime and anywhere.

I haven't used it.

You're too little power.

I use a donkey that travels the world at 16,000 mAh.

In order to achieve the best performance of the power bank, you need to activate the internal battery first, and the activation steps are as follows:

1. Discharge, discharge the newly purchased mobile power supply first, such as charging the mobile phone or other electrical equipment, and discharge until it is protected;

2. Charging, charge with the adapter carried by the product itself (if there is no adapter, you can choose 5V 1A), do not stop when the display is full, continue to charge for 4-6 hours;

3. Then put the bending socks on the battery to balance the excitation, and put it until it is self-protected;

4. Continue to fully charge, repeat the bar 2 times, basically activate the battery, so that it can have a more ideal alarm discharge depth and capacity, in order to achieve the best performance.
