I can report a first-time run of 15 straight hours with the minime AES out into a r-44, 48V phantom powering our Busman mic
Went down to a single LED, and I stayed there for the last hour, then ended the test.
If it charges in 9 hours, that's a full day's work......PASSED
2 DVD batteries to power the r-44 were enough for the 15 hour test
