kenemon 29 Posted July 12, 2012 Share Posted July 12, 2012 Hi Guys, I am trying with futility to run a wireless router off battery power. I picked up a LM2596 DC-DC Step down Adjust Power Supply Module and set it at constant 5volts from a 12V battery. I cannot get the device to boot. Any ideas? Is there some kind of frequency issue? thanks. KB Quote Link to post Share on other sites
fcobcn 2 Posted July 12, 2012 Share Posted July 12, 2012 Make sure that your router needs DC, I have seen a lot of models using 12v AC power. kenemon 1 Quote Link to post Share on other sites

kylej1050 27 Posted July 13, 2012 Share Posted July 13, 2012 Was the supply maintaining 5v when plugged in? It may have been sagging. kenemon 1 Quote Link to post Share on other sites
kenemon 29 Posted July 13, 2012 Author Share Posted July 13, 2012 i short metered both amps and volts before i hooked it up, i am assuming it must have a surge demand at the initalization. important to the efficiency/drain calculations for the battery. thanks Quote Link to post Share on other sites
