i am having problems with powering a MUSTEK pvr 400.
the internal battery gives me 45minites of recording time. if i use the mains power unit (output 5v 2a) i can extend the recording time to 4 hours.
so i thought if i buy a car adaptor and connect it to a 12v battery this would extend the time as well.
i bought a 12v 3a adaptor from maplins and connected it to a 12v 7ah yuasa battery but found that it didnot extend the time at all. before i throw any more money at this can anyone tell me what i am doing wrong. thanks.
