I-Series power consumption, battery runtime and charging
The power supply of the Tobii Dynavox I-Series (for the device models I12, I15) and I-Series+ (for the device models I12+, I15+) operates at 24 Volt with a maximum of 2,71 Ampere. This means the power supply will provide a maximum of 65 Watt which corresponds to 65 Wh maximum power consumption. The exact power consumption is very dependant on the use case, the screen brightness, etc. but in normal use the device will consume much less power than that. As a comparison, a regular LED flat screen TV can consume around 130 Wh.
