All my modems want to draw 1 to 1.5 amps at 9 or 12V, which would correspond to 1.8 to 3.6 amps at 5V, but USB cables aren't rated to anywhere near that amperage. Sounds like you should buy a UPS to me. You can get pretty cheap ones these days, eg $75: http://www.msy.com.au/home/13486-eaton-5e650iusb-au-5e-650va-360w-ups-with-2-x-outlets.html You could build your own out of a 12V battery, battery charger, and a 12V regulator, but it'll still come to over $50 and be a mess of wires.. http://www.jaycar.com.au/productView.asp?ID=SB2485 http://www.jaycar.com.au/productView.asp?ID=MB3523 http://www.jaycar.com.au/productView.asp?ID=MP3678 _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
