How long can it be used on a single full charge? Does it need to be charged frequently?

The LiberNovo Omni is equipped with a 2200mAh 12V battery. While battery life varies depending on frequency of use, a full charge can last up to 30 days if you use the full traction and stretch functions once a day, or up to one year if you only use the motor adjustment button about three times a day. The battery powers the chip-controlled dynamic support and massage functions. Since frequent charging is not required, it's ideal for long-term use in the office or at home.
