ATXRaspi Specifications - Maximum current

Hi,

I have been looking everywhere and I don't know if its just in plain sight and I missed it.  But I'm looking for the ATXRaspi's data sheets. 
More specifically I want to know the devices current rating.

I'm building a PiPad and I need to power up a 10" LCD which draws 1.5~2.0A.  I also want to power the Pi and a small USB hub, I guess the total maximum load on the ATXRaspi will be around 4A.
 
The other problem I have is that the USB battery pack that I have will only supply 2A per USB port.  How I combine two ports safely to one ATXRaspi board?

Thanks,

Marco

Marco,
ATXRaspi is a RaspberryPi switch and it's not designed to carry a lot of current. The current rating for the switching mosfet is 2.5A, but I would keep it below that. I cannot give any guarantee if you load more than a typical RaspberryPi with the typical devices attached (wifi dongle, HDMI, keyboard, perhaps a HAT etc). Any other heavy current devices should be powered separately, the same way that Raspberry Pi recommends.
