^ Sir yung power is USB. Yung recording, pwede naman i-loop. Tapos automatic i-ni-split ni gopro yung files (could vary from 3, 6,...minutes). Let's say you had a 10 minute drive. Kapag tiningnan mo yung SD card mo split sila. Could be in 3 files, two 3-minutes and one 4-minutes video. Or random, depende sa reason na hindi ko alam.
