◆ Gone are the days of having to use one plug point per battery. It allows you to charge three batteries at the same time with no fuss.
◆ To make charging process more convenient, it can be powered by several different types of power supply, such as a standard phone adapter, car charger, AC/DC mains transformer, USB socket, power bank or solar panel.
◆ Each battery is independently monitored and its charging/full status is shown by a red or green LED, so battery units can be replaced for charging as and when.
