I have v1 of the Tinybox. I did some reading and never really saw any accurate battery times, or none that I felt really reflected my set up. With the changes in revisions, etc. I figured that the most accurate info was going to be to charge it to 100%, hit record, and let the puppy run. I started recording with my CCM4>Tinybox>M10 in front of one of my VR-4jr's and Foobar playing random master recordings.
I started around 8pm last night and it was still going at 8am this morning when I left for work. The light on my Tinybox was still green.
My neighbors are going to hate me.
