The xDSD will draw the maximum safe current from any power supply unit (PSU), using the standard ID methods (Apple, Samsung, USB standard). Any standard-compliant PSU should signal it’s current limit and the xDSD will then use this current limit.
We do not recommend the use of non-standard compliant PSU’s.
The xDSD will charge at up to 1.1A and will, in addition, draw around 300mA to operate if the power supply is capable of providing this current level. If the PSU cannot be identified using standard methods, the xDSD will test the maximum current the supply can provide without dropping the output voltage below set thresholds, and then operate at this current limit. As an absolute maximum, around 1.4A may be expected if playing and charging a fully depleted battery.
