I invite one battery in the supplied station on while I'm with the other go, or I'll take the second battery to have double the runtime. For the supplied battery box is ideal.
Although is not a double-charging cable, but that fits the Smartphone.
If you want to invite both batteries at the same time, you need a second mains adapter or a USB connection cable.
The charging time in the charging cradle is similar to the smartphone. If the battery is full, the LED is green.
The times when you had to wait for hours until the battery is charged, or had to leave the house with half or even less charged battery, are finally over.
I'm excited!
