Mscaler pulls requires 12-15 watts. It runs perfectly on 12 watts from lifepo4 batteries. When on full 1 million tap upsampling it only pulls 10 watts total. So a medium sized lifepo4 battery will give you 24 hours of use. I use the Bluetti EB55, I have two of these power stations on rotation so one’s always ready, each given exactly 24 of use. I am using the 2.1mm to 2.5mm Ghent Audio Gotham quad shielded power cables and Audiowise DC RF-Stops for as perfect as it gets black background. Once you taste lifepo4 in your system it’s hard to go back to A/C. It’s just so much better than any hi-end power conditioner.
