Most mobile phones now use a non-removable back cover design, which makes the phone battery that is stretched by itself undoubtedly even worse. The emergence of mobile power, to a certain extent, has become the most effective means of making up for the lack of mobile phone life. In this article, let's take a look at the issue of the number of times the mobile power is charged.
First, the power
We often see mobile power supplies ranging from tens of thousands of milliamps to hundreds of thousands of milliamps. Even if there is no virtual standard, so much power does not mean that it can be charged to your mobile phone. The rated capacity is not equal to the actual available capacity, and some electricity is lost during the storage of the power.
For example, if the battery pack has a capacity of 5000 mAh, there is now a 2500 mAh smartphone that needs to be recharged. This does not mean that you can charge your phone twice. Because there is a problem with the conversion rate of mobile power and the conversion rate of mobile phones.
Second, the output conversion rate
The conversion rate is an important criterion for judging the quality of a mobile power supply. If the conversion rate of a general mobile power source is about 80%, that is, the actual output of a 10,000 mA mobile power supply is only 8000 mA.
Third, mobile phone conversion rate
The mobile phone also has the concept of conversion rate when charging, because the mobile phone circuit board also consumes a part of the power when the mobile phone is charging, because the mobile phone itself is somewhat hot when the mobile phone is charging, which is the power consumed by the mobile phone is converted into heat energy. Most mobile phones have a conversion rate of 80%-90%.
Fourth, the number of charging
Understand the above concepts, we can roughly calculate the mobile power can give the phone a few times.
Charging times = power of mobile power * mobile power conversion rate * mobile phone conversion rate / mobile phone battery capacity.
For example, a mobile power of 10000 mAh has a conversion rate of 80%, a mobile phone conversion rate of 90%, and a mobile phone battery of 3000 mAh. Then, the number of times it charges the mobile phone = 10000*0.8*0.9/3000= 2.4 times, basically 2-3 times or so.
Solder Cup Waterproof D-Sub Connector
The Solder Cups D-sub connector, also known as Solder Cups D-sub connector , typically contains a pin layout of 9 pin, 15 pin, 25 pin, 37 pin & 50 pin positions housed in increasing shell sizes accordingly. They are available in both male (plug) and female (socket) variants with the male signal contacts/pins (current rating of 5A) spaced every 2.76mm in horizontal rows and the spacing of rows vertically at 2.84mm laid out half the distance between pins of existing rows.
