How long does the charging process take until the C3+ is fully charged?

Hardware Battery Charging

The C3+ automatically charges as soon as it is connected to the computer or charger via the micro USB cable. PLEASE NOTE: DC voltage of 4.75-5.5 volts. (The speed of the charging process may depend on the computer the C3+ is connected to). Depending on the charger and the battery level, it may take up to approx. 2 hours until the LED lights of the C3+ lights up green indicating that the battery is fully charged. A 7-day-recording requires a charging time of the C3+ of approx. two hours.
