My setup that is working great.
Pineapple Mark IV, New Trent 11000MaH, MC760 Novatel Virgin 3G Modem, (This has a micro SD card slot built in).
Can power all this for about an hour and half, less with the more connections obtained.
You do have to find a USB to Type M Barrel cable to run from the New Trent USB Battery Pack. This provides you the juice you need.
You have to make sure each time you intend to use, that the New Trent is fully charged. For some reason the output seems lower when the New Trent is not
fully charged when you power it up. Not sure if this some kind of issue or what. The rig is pretty small, so it can be concealed easy.
