power bank as an external device , the functionality of their products is very clear - the emergency supplemental power, use of the product away from the indoor scenes are mostly scenes of life , such as travel, outdoor activities , travel , etc. , imagine , If a power bank, its capacity is sufficient , batteries also a-level , but the charging speed is very slow , power bank naturally greatly discounted convenience , this is like , driving a BMW walking in the cement on the road , they can not understand the feeling of pleasure .
power bank charging speed is mainly to see the mobile power supply output current, present, mainstream output current , 5V/0.5A, 5V/1.0A, 5V/1.5A and 5V/2.1A 's . Because each device required rated current is not the same , such as iPhone4S/iPhone5 is 5V/1.0A, iPad is 5V/2.1A. Suppose you give iPhone4S with 5V/1.0A Charging takes 2 hours , then if there is 5V/0.5A requires four times , or more. iPad is the reason , 5V/2.1A need five hours , then , 5V/1.0A require 10 hours or more, this was reflected power bank for different output currents bring convenience , but also a lot of people overlook .
Is charging speed really important to you ? I think that this is still very important, but the premise is , you can not damage digital equipment . Emergency situation, even in the wild, fast charging is a very important function. In the absence of these features, then this would not be regarded as a portable power bank .
Such as the above example , 5V/1A can be used in mobile phones , 5V/2A can use the tablet and mobile phone , which is basically enough , then a big mobile phone also can not charge electricity.
