Buy mobile power, polymer batteries and lithium batteries (cylindrical batteries), 1W capacity will be enough, which is good?
The main components of the mobile power are: the core and the circuit board, there are two kinds of electric core, one is the polymer core, and the other is the 18650 core. Polymer core is better, if you buy mobile power, it is recommended to buy brands of mobile power! If it is not high demand for mobile power, you can choose Xialong for mobile power, dragon for this brand, the current online can be found! Hope to help you ~!
Each has its advantages and disadvantages!Cylindrical relatively high cost performance, but the volume limit, the appearance of relatively heavy;The thickness of the polymer is thin, the size can be freely chosen, made of mobile power is more fashionable, but the price is relatively more expensive.
I tell you this, their production materials are the same, the main difference in the process above, to the pursuit of small volume, expensive points, the same capacity, cylindrical cheap. You see, laptops are made of cylinders, and mobile phones use polymers, because the phones are limited in volume, and the 2 have almost the same service life. You can make your own decision now. Some people say that the cylinder will explode, but this probability is one millionth of that, because the cylindrical battery itself is designed with double insurance. Plus the external circuit insurance, you think about it... Heard of a laptop explosion, just heard the phone explosion.
2., when shopping, we can refer to the following points:(1) choose more well-known mobile power brand, the quality of products may be better, and future after-sales service more in place.(2) from the security point of view, try to buy metal shell mobile power supply. Because the metal shell acts as a radiator in the product structure of the mobile power supply, the heat of the lithium battery can be distributed through the metal casing, thereby reducing the risk of fire and explosion.(3) capacity size should be chosen according to the use, too large to carry inconvenience. And pay attention to the power supply after the end of the timely power-off, to avoid prolonged exposure to the risk.
1., both have their own advantages, can choose according to their own circumstances.(1) the lithium battery (cylindrical battery) is limited in volume and relatively thick in appearance. But the cost performance is high and the technology is relatively mature;(2) the same capacity, polymer batteries, sophisticated, fashionable, mini, easy to carry. But the price is relatively more expensive.
