The speed of mobile power charge is extremely important

Tablets and the popularity of smart phones, let mobile power into digital control essentials of daily life. Consumers buy mobile power supply in time, all can discern batteries, compare the capacity, even ask the real output of mobile power supply capacity, but the majority of consumers of mobile power supply charging speed this index is not pay attention to understanding.

Mobile power as A kind of external equipment, the functionality of the products is very clear - emergency power, product usage scenarios are mostly from indoor life scenarios, such as travel, outdoor activities, travel, etc., imagine, if A mobile power supply, its capacity is sufficient, batteries is A grade, but the charging speed is slow, so that the convenience of mobile power supply natural big discount, this is like, driving A BMW to walk in the way of the soil, natural cannot grasp the speed.

Mobile power supply charging speed mainly is to look at the mobile power supply output current, for now, the output current of the mainstream is A, 5 v / 0.5 A and 5 v / 1.0 A and 5 v / 1.5 A and 5 v / 2.1 A. Due to the requirements of each device rated current is different, such as the iphone 4 s/iphone 5 is 5 v / 1.0 A, it is 5 v / 2.1 A. If you use 5 v / 1.0 A recharge the iphone 4 s need 2 hours, so if there are 5 v / 0.5 A it need four, or more. The same is true of the device, 5 v / 2.1 A need 5 hours, 5 v / 1.0 A requires more than 10 hours, this is the mobile power supply output current of different convenience, is also A lot of people ignored. , of course, in addition to the output current, still need to see a parameter is the stability of the output current, is also called the discharge curve, because if the mobile power discharge is not stable, foreign set equipment is a damage, this is also a lot of businesses will suggest consumers don't use a computer to recharge the phone, because in the process of using, the computer output current is changing.
