Charging treasure has played a very important role in daily life. When we travel, charging treasure is an essential item to carry. When our mobile phone is out of power, the mobile power supply will renew the life of our mobile phone.
What is power bank?
A power bank is actually a large-capacity portable power supply that is convenient and easy to carry. It is a portable device that integrates power storage, boost, and charge management.
How to choose a power bank?
1.Choose regular brand power bank
Check whether the product certification of the manufacturer of the power bank is complete before purchasing. Buy power banks as much as possible from regular and guaranteed websites. Whether there is a complete after-sales service, when there is a problem with the power bank, it can avoid a lot of trouble.
2.Pay attention to battery cells
The power bank relies on the internal battery to power the mobile phone, so the quality of the internal battery plays a decisive role in the performance of the power bank. There are generally two types of charging treasure batteries on the market: polymer lithium-ion battery and lithium battery.
(1) Polymer battery: Compared with lithium battery, polymer battery has the characteristics of light weight, small size, safety and high efficiency.
(2) Ordinary lithium: There are many refurbished batteries of ordinary lithium batteries. Due to the process, the problem rate and failure rate remain high. The general public cannot distinguish them. The system is large, heavy, short service life and may cause explosion, which is very fatal. The current mainstream mobile power supply is gradually phasing out this kind of battery.
3.Battery charge display
It is best to buy a charging treasure with a power display, so that we can also know exactly how much power is left in the charging treasure and whether it is full, so as to ensure that we use the charging treasure correctly.
4.Note the input and output parameters
The main requirements of the output parameters of the power bank are similar to those of our mobile phone original charging adapter.
5.Note material
Especially the materials used for key components in the internal structure of mobile power supplies such as booster systems and capacitors. If the materials used in the production of charging treasures are unqualified, there will be great safety hazards, and even serious explosions.
