1. How to use the mobile power bank?

 

  1. It is very easy to use the power supply to charge the mobile power supply. All you need is a USB cable, charger and wall outlet box. Plug the USB cable into the power bank, and then plug it into the wall socket. The red light should appear. This lets you know that the charger is not fully charged and it is accepting charging. Keep the power bank plugged into the wall until the indicator light turns green, and then unplug the power cord. You may need to keep it plugged in for several hours before it's fully charged.

 

  2. Now that your power bank is fully charged, it is time to start using it. All you need to do is to connect the USB plug into the power bank, and then connect the USB female plug to your phone. Pay attention to the battery icon on your phone. If the battery icon has a lightning bolt through it, it means it is charging.

   3. The mobile power bank is designed to fully charge mobile phones. In order to get a fully charged battery faster, please turn off your phone until the battery on your phone screen is fully green. You can continue to use your phone.

 

   4. If you do not see the lightning bolt on the battery icon of the phone, it means that the charge will not be transferred. Try to plug it in again, if it still does not appear, the power bank may be malfunctioning.

 

2. The mobile power bank cannot be charged?

 

Question 1: The mobile power supply is exhausted and cannot be charged.

Solution: If the newly purchased mobile power cannot be charged, it is probably because the mobile power is exhausted and naturally cannot support mobile phone charging. How to tell if this is the case? Immediately charge the mobile power supply for 3-5 minutes. If there is an indicator light, it will light up, which means that the mobile power supply is back to normal.

When charging the mobile phone, pay attention to whether the power bank indicator will be on

 

Question 2: The charging cable or adapter fails to charge.

Solution: Use the charging cable of your mobile phone to connect to the mobile power supply to replenish the power.

 

Question 3: The mobile power indicator is broken.

Solution: Immediately charge the mobile power supply for half an hour and then stop storing it. Connect the mobile phone to the mobile power supply. If there is charging on the mobile phone screen, it means that the mobile power indicator is faulty. There should be no other big problems with the power bank itself.

From the current point of view, the situation that the mobile power supply is exhausted and cannot be charged is the most frequent occurrence, and consumers do not need to worry too much. If it is the latter two cases, you can contact the manufacturer to solve the problem as long as it is within the warranty period.

four. Large-capacity mobile power charging treasure detection:

 

Test method: Fully charge all the products to be tested, and after disassembling, separate the battery cell from the circuit board, use the 3.7V parameter, directly connect the battery cell to the test equipment for "streaking" discharge, and finally get its actual Capacity value.

A qualified mobile power evaluation standard: the actual measured capacity of the internal lithium battery of the mobile power is greater than the nominal value of the product outsourcing.

Problems that are prone to appear in the experimental test: the conversion rate is not up to the standard, the heat dissipation is not up to the standard, the capacity is exaggerated, the use is not smooth and the production process is not perfect. Among them, the first three factors account for a relatively large proportion.

Reminder: The mobile power capacity test is conducted by a special third-party organization. Consumers should not disassemble the battery for testing! ! !

 

Buying advice:

① Choosing a regular large manufacturer greatly reduces the risk of buying a second-hand disassembled battery. In addition, large-scale merchants attach great importance to market reputation, and ordinary consumers can attract the attention of relevant merchants in their complaints. In addition, in terms of the convenience for consumers to accept after-sales service, large enterprises have accumulated a lot of after-sales service process and experience, and it is easier and faster to help consumers solve problems.

 

②Be rational when buying mobile power. Too high-capacity mobile power is more uncontrollable, because the higher the mobile power capacity, the more difficult it is to control internally, and the more likely it is for safety accidents to occur. In addition, as the capacity increases, its price also rises accordingly. In fact, consumers should pay more attention to the price, volume, and capacity of the product when buying a power bank. For example, when you buy a 20000 mAh power bank, its volume is as big as 3000 mAh, and the price is similar! Basically, it can be judged that the data of this kind of power bank exaggerates the capacity, and consumers must not buy it.

 

V. What is a polymer mobile power bank?

 

It is also a kind of lithium ion battery, but compared with liquid lithium battery (Li-ion), it has many obvious advantages such as high energy density, smaller size, ultra-thin, lighter weight, and high safety. New battery. In terms of shape, lithium polymer batteries have ultra-thin features, and can be made into batteries of any shape and capacity to meet the needs of various products. The minimum thickness that this type of battery can reach can reach 0.5mm. Its nominal voltage is the same as Li-ion's nominal voltage of 3.7V, and there is no memory effect.

 

Lithium ion battery classification: liquid lithium ion battery (LIB), polymer lithium ion battery (LIP)

Advantages of polymer lithium ion battery:

① Ultra-thin, the battery can be assembled into a credit card;

②Flexible shape: The manufacturer is not limited to the standard shape, and can be economically made into a suitable size;

③Light weight: The battery using polymer electrolyte does not need a metal shell as a protective outer packaging;

④Improved safety: overcharge is more stable, and the probability of electrolyte leakage is lower;

 

insufficient:

Compared with lithium-ion batteries, the price and energy are relatively high

 

Advantages of liquid lithium battery:

The thicker the liquid lithium, the better it is to produce. The battery with a thickness of less than 4mm is difficult to produce. Even if it is produced, the capacity is obviously not as good as the polymer lithium battery, and the cost is not advantageous. Therefore, the thinner the battery, the lower the polymer production cost and the higher the liquid production cost.

But for thicker specifications, the liquid lithium battery supply chain is mature, the technology is mature, the production efficiency is high, the yield is high, and it has a strong manufacturing cost advantage. Judging from the current market, although the liquid lithium batteries of the 5mm and 6mm thickness series have much higher capacity than the 3mm and 4mm thickness series batteries, the price is much lower.
