I have 1 & 2 amp USb ports on a 20,000mAh battery. I 'm suspicious that because the battery output is 5V, the SD442 (5-18V DC snput ) the machine just thinks the externals battery is dying?
Update: SD442 had no issues running on 5V USB power and supplying 48V phantom power to 4 mics.
Wow....this is great gonna have a cable made for my mixpre!
