The introduction of mobile power lithium-ion batteries charging treasure

Source: 2020 - 03 - 25 'hits: lithium battery mobile power charger is introduced and the matters needing attention? Introduction of charger charger what is treasure, that is, we often say the mobile power supply. A set of power supply and charging function, which integrates a portable charger, may at any time and place for mobile phones, tablet computers and other digital devices. Generally by the lithium battery ( Or dry cell, is rare) As a storage unit, easy to use. It has certain emergency function, in the case of many digital power cannot store electrical energy, some equipment to the power supply, in order to achieve the effect of the normal work of the digital products. Charging treasure classification ordinary function mobile power supply on the market at present is one of the mainstream mobile power supply type, they don't have any extensions, can charge and discharge. Most of their shape more fashionable, and using the flexible packaging battery, belongs to professional external portable mobile power supply. Multi-functional mobile power supply this kind of portable power supply is also one of the more popular. In addition to charge and discharge function of mobile power supply, integrated with other practical functions, such as LED lighting, LCD display, etc. Which has the function of solar battery charging mobile power supply this kind of portable power supply is equipped with solar panels, can be recharged by the sun in the process of use. This kind of mobile power supply is not very practical. Ac plug type portable power folding ac plug portable power supply can be folded into type portable power supply, can be directly inserted into the household electrical outlet to charge of the product itself, integrating the charger and mobile power supply function, more practical portable. Built-in rechargeable linear portable power supply in addition to charging for digital products, users need portability of mobile power supply. Built-in rechargeable line, the user can't find a charging line and adapter. Stitching/demolition of mobile power supply multiple independent power splicing can expand the overall power supply ability, meet the large demand. When the power is very small, can be divided into small capacity power, reduced the load weight, and don't delay. Wireless charging portable power supply does not need to insert the USB line, also do not need to connect the power cord plugs, can achieve a portable wireless charging in outdoor mobile power supply. Tablets tablets, mobile power supply, to solve the problem of the tablet to use time is too short. Mobile power supply capacity is big, can be in the mobile anytime, anywhere provide continuous power supply for the tablet. Mobile charger of battery life in general, standards for the import of 18650 A battery products, use frequency is about 500 times, the domestic first-line brand is right also. But the life of the second-tier brands in 300 - basically 400 times. The greater the power of mobile power supply capacity, the longer the total lifespan, because usually mobile power supply capacity, the greater the fully after use, the longer the longer natural life. Circuit board is equivalent to the brain, mobile power supply with high quality PCB more durable, more easy to use, safer, if it is a mobile power supply with inferior circuit boards, more trouble, easy to damage the mobile phone, even there is a risk of explosion. The attention of the battery charging time treasure battery capacity because of the influence of the market there are many types of mobile power capacity, such as 2200 mah, 3000 mah, 4800 mah, 8000 mah, 18000 mah, etc. , of course 2200 mah and 18000 mah under the condition of the same charge time must be different. Theoretically the influence of charging current, charging current, the greater the shorter the time needed for mobile power full charge, but the standard charge and discharge current is zero. 2 c, such as mobile power supply of 5000 mah, charging current is commonly 5000 * 0. 2=1000mA。 Mobile power charging time = battery capacity/charging current, for example: 5000 mah mobile power, input voltage, current for: 5 v, 1000 mah, so mobile power full time = 5000 mah / 1000 mah = 5 hours. And, of course, there is no any loss, so theoretically charging time is longer than 5 hours a bit.
