They all used 5VDC and there was no point in using 3 adapters.=20 I just bought a larger current adapter and put them all on it. I also=20 have a wdtv live player, usb hard drives powered off a single 12VDC=20 adapter , rather than the 3 it would take normally. Some devices are not designed to share grounds with other devices. My=20 cordless phone would have audible hum if connected to the voip adapter=20 and the same power source. It also would not ring while they shared the=20 power ground. Otherwise everything worked out fine and things like=20 routers, modems, hard drives don't seem to have any issues.
