GS90A19-P1M Power Supply AMP+ RPI2

Is the GS90A19-P1M 19.0V @ 4.74A too much for the AMP+ and Raspberry PI 2 ??

This unit has more wattage then the 60W but pushes at 19Volts. The RPI2 quad core CPU has to take more power, right?

The other option I have is a 33 Amp/hour 12V SLA (sealed lead acid) with a 2amp battery tender. Do the boards run better with the higher voltage DC P/S? The SLA battery will have a 12-14.4 voltabe range which may not be desireable.
