How much is the battery capacity of the shared charging bank

1.the output voltage of the shared charging bank is 5V, and the capacity of the battery is 5200mAH. So the capacity of the battery is generally about 5200mAH.

2. Many computer friends habitually rent shared charging banks when their mobile phones are out of power. What they consider more when renting is the price of renting, the capacity of charging banks or
   The output power. It’s normal and okay to care. But there is one thing we can’t miss, that is the rated capacity of the power bank.
3. Why should we pay attention to rated capacity? Because the rated capacity is related to how much power you can charge your phone with the power bank you rent. The rated capacity is the amount of power that is actually put into the phone’s battery when the bank charges the device, after deducting all the losses. So it doesn’t matter how big the capacity of the battery bank is. What you need to focus on is how much the battery bank can actually charge my phone, so focus on the rated capacity.
4. why the charging bank to the mobile phone charging bank will have a loss, the amount of loss depends on what? In fact, the simple explanation of this problem is that there will be resistance and consumption in the charging process. And heat is an obvious loss phenomenon, so there will be power loss in the actual output and input process. So the actual input to the battery of the mobile phone naturally cannot equal to the actual capacity of the charging bank. The amount of loss mainly depends on the material, such as the battery of the charging bank. The material of the charging cable, of course, and the design of voltage upgrade and degradation
