Looking for a cable to wire a Roku Ultra 4670R in an RV. I haven't been able to get specifications for power (connector, voltage, etc.). Does anyone know if there are ready made cables, maybe USB to Roku Ultra power?
I just looked at the power supply for my 4670. It is rated at 12 VDC and 1.5 amps. USB only provides 5 VDC and 0.5 amp. So no, you can't power it with a USB cord. You really need to use the power supply that it comes with. Powering a Roku player with the wrong power source can cause all sorts of problems, and possibly damage the player.
