If the Keces P3 is particularly interesting it is also because it offers two adjustable DC outputs. Thus, the first output can be set to 5V, 7V or 9V, while the second output can be set to 12V, 15V or 16V. A switch on each output allows you to simply select the desired voltage. On the current side, each output provides 2A (Maximum 3A at peak). The input voltage is also selectable (230V or 115V AC) via a switch under the device, to adapt to the current supplied by your mains sockets.
