The written Volas Vitality™ MagicPro 2.0 listing is short. The photos carry most of the product identity.
You can see a white U-shaped frame, two inner padded contacts, two rounded upper contacts, three side buttons, and a small side opening. The listing does not name that opening as a specific charger. The photos do not prove battery size, modes or a medical result.
Look through the Volas Vitality MagicPro 2.0 image set before you decide.
