1, the plastic shell, low cost, metal shell, delicate, the battery has 18650 steel shell lithium battery, large capacity, large weight, but the quality of the battery is uneven, and the use of this battery charging treasure bodyThe product is too large. Many now use polymer lithium-ion battery holder charging bank cell, this cell is safe to use, and can be made very thin, is currently the most common cell.
2, charging treasure shell what material good metal material Metal charging treasure, presumably everyone is no stranger, bright metal luster, can immediately catch your eye, chic metal shape, fully show the essential charm of metal material.
3, generally speaking, the non-metallic shell is made of ABS/PC plastic material, with the characteristics of low ignition point and high temperature resistance, and the mobile power supply has a long time high temperature outsideThe shell is also not prone to melting or burning, which is very helpful for daily use. When the two products are the same volume, the plastic shell is lighter and more portable.
4, What are the types of charging treasure batteries? Commonly used polymer lithium battery, 18650 lithium battery, AAA nickel-metal hydride battery. Polymer lithium-ion battery: standard voltage 7 V, more shapes, can be customized, with large capacity, stable performance, volume and shape arbitrary, generally soft package form. At present, many charging banks on the market in order to reduce costs and fight low prices, the use of low-quality 18650 cells, called civil air defenseDefence.
1, but Huaqiangbei wireless charging shell material Unlimited magnetic charging treasure Wireless charging shell material , if it is to buy a double-digit version wireless charging shell material , thatI think its quality should be very poor, it is recommended that you buy about two hundred yuan Huaqiang North wireless magnetic charging treasure will be better.
2, because so spreadThe energy loss in the process is small, and the transmission efficiency is high, so as to ensure the normal endurance of the load.
3, but the design of the glass shell rear screen can effectively reduce the loss of energy transmission and reduce the generation of heat, energy can be better transmitted through the communication of the two coils, to ensure that the electronic device will not produce too high heat energy when charging the mobile phone and mobile phone battery damage; And the electrical conductivity of the glass is almost zero, which means that too much heat will not be generated in the process of wireless charging. Signal transmission.
4, Apple is the rear glass is to improve the signal of the device, the metal shell of the device signalIt will have some effect. Today's mobile phones have a common appearance, that is, the back cover of the mobile phone is all made of glass design, and from high-end to low-end, many models have adopted this design. Glass has a better signal than other materials, and metal can reflect the signal, causing problems with signal reception.
5, in addition to the glass body has a lot of advantages, such as not easy to occur paint, corrosion and other problems, and tempered glass will not occur after the shell scratch problem, with the development and growth of the glass body, now can be converted into a variety of beautiful colors, to promote the mobile phone shell more and more beautiful. <
