Mobile wireless charger
						Wireless charger refers to the charger that does not need to be connected to the terminal equipment that needs to be charged without the traditional charging power line. It adopts the latest wireless charging technology. By using the alternating magnetic field generated between coils, the inductive coupling technology will become a bridge connecting charging base station and equipment.
					 
					
						portable source
						portable source(Mobile Power Pack,MPP),It is also called power bank, travel charger, etc. it is a portable charger with power supply and charging functions, which can charge mobile, tablet computer and other digital devices anytime and anywhere. Generally, lithium battery cell (or dry battery, rare) is used as power storage unit, which is convenient and quick to use.
					 
					
						Polymer cell
						The advantages of polymer cell lie in its strong endurance and large capacity. The capacity of polymer cell with the same volume is 20% larger than that of lithium battery cell. Under the condition of stable current output, the battery has strong endurance and its surface is flexible material. If the battery bulges due to short circuit, it will not explode, it will only crack, so it is safe
					 
					
						Battery pack
						The battery pack is divided into series and parallel. The parallel battery pack requires the same voltage of each battery, and the output voltage is equal to the voltage of one battery. The parallel battery pack can provide stronger current. There is no excessive requirement for series battery pack.
