i have idea to step-up 5v usb to 9v because 5v usb plug now is standard for all, now new car have usb plug too and adaptor is simple to find.searching i find on ebay this:http://cgi.ebay.it/2PCS-1V-5V-to-9V...AU_Gadgets&hash=item3a5d19f650#ht_2179wt_1138or this:http://cgi.ebay.it/IC-VALOR-PM7202-...pt=Bauteile&hash=item588221a652#ht_500wt_1154but this are 350ma or 200ma max output.for pm7202 i think use it in paralell 2 or 4 for take 400 or 800ma max output and for have little package.but i don't know how many milliamper need m001 to work.i know only power adaptor permit max 1.5A but in real how many absorbs really?sorry but my m001 not arrived (it now stay in frontier i need wait ).

Exactly my point - if you use external adapter for charging through the charging port, then there is no need for the word USB (as you have written in the title), because you neither use the USB port on the device to charge it nor use USB port on a PC as a power source. You just have an adapter 110-220V to 5V and you want to use it to charge your M0001 - there is nothing USB in that. At least that's what I understood from what you said. Correct me if I'm wrong.
