Multi Voltage for more devices

As a touring cyclist and the owner of a few Anker products, I want a product that almost does it all. One weather proof box that has the following:
USB 2 amp 5v, 9v 5amp, 12v 10amp, AA and AAA Plus 9v PP9 charging cradle, 15v USB for ASUS Transformers, plus 19vdc 7 amp for laptop charging, 12v cigar socket plus a range of adapters plus a drawer for cables. I did make one using various power supplies but Anker could do a much better job. It could measure about 300mm by 200mm x 100mm and would weigh 4kg and would fit in a Ortleib front pannier bag. I would pay £300 what a dream come true.

Does the powerhouse not cover most of these requirements? It’s even the correct weight.
