Power supply question for streamer

Six of one, half a dozen of the other.

Your 15V/1.5A is already overpowered.

Does the PS get really hot?  1.5A seems a little low for the device.

For a little over $100 you can get a 12V 18Ah Lithium LiFePO4 Deep Cycle Battery and charger that will give you clean power for almost 8 continues hours.  Need more time?  Just buy two batteries and charge one while the other plays.

The specs are 9-15 volts so you are at the top of the range and should be fine.  I bought a 12 volt LPS to split the difference.

I also bought a 12 volt for mine, but as Jack states above, it is rated for up to 15 volts. 

just get the iFi iPower Elite 12v or 15v. 

+1 on iFi iPower Elite. Like sBooster too

Another good option for less than the Power Elite is the LHY power supply built by Jays Audio.
