电池充电器 / Battery charger

电池充电器
电池充电器

This charger can not only charge up a battery, but also check the battery level. Most of the time, when we get a battery, we don’t know whether there is any electricity in it. In other words, we are not sure whether the remaining power can meet some of our needs and whether the battery needs to be charged. If we have such a charger which can show the state of charge according to the LED aureole, it will be very easy for us to choose.
