How to learn if the portable power supply if fully charged enough?

Generally speaking, there are four LED lights on the portable power supply, to be the charging status indicating light. When charging, the light will be twinkling and users will learn about the remaining power energy. It is very easy to figure out if it needs to be recharged. Of course, it is not recommended to charge by laptop USB interface port.

How to calculate the recharging cycles of the portable power supply for cell phone?

Actually, the recharging cycles are not determined by the capacity of batteries. All the portable products should have their own indicating capacity for themselves. And some digital products have the nominal value for output voltage, which users need to pay attention to if they can be compatible to the laptops.
