The USB-type AC adapter and included USB cable free you from worrying about battery life, as well as charge many other devices using USB. The cable provides connectivity between your H1 and any Mac or PC computer. The adjustable tripod and mic clip adapter make it easy to point the Zoom H1 recorders stereo mics toward your soundstage for best imaging. And lastly a padded-shell case offers protection for this great little device.
