Don’t let battery life dictate your recovery! With a backup battery, you can rest assured you don’t run out of juice mid-recovery.
The backup battery offers 2 hours of BioZoom use (when used on the highest intensity level). Use your BioZoom and charge your backup battery simultaneously, thanks to a charging port located on the top of the battery itself.
When used on the highest intensity (level 5, 60Hz) 1 charge provides 2 hours of use. On lower intensities battery life is extended and 1 charge provides over 2 hours of use.
