External Battery For MPC X!

Hey guys been a while! Has anyone got any insight as to whether there's a battery pack out there that could be used to power MPC X? Or as a spare for MPC Live? Specs are 19v 3.42a for both units. Thanks.

I use this for the Live and it will no doubt work for the X.

Fits in my UDG Producer bag with my other man bits..

Thanks for the link! Perfect!

This one is stellar !!
