The charger for the vehicles of the Viessmann CarMotion system can be powered by any commercially available USB power supply unit or by almost any device such as PC, laptop, power bank etc. With the enclosed cable, the charger can be connected to a USB-A power supply. The charger's plug just needs to be inserted into the socket underneath the CarMotion vehicle. An empty battery is recharged within 35 minutes. A partially discharged battery requires correspondingly less time to be recharged. The current charging status of the vehicle during the charging process is indicated by the interior lighting of the vehicle flashing in 4 steps.
