vibrator charger

Each listing indicates single-device charging: one battery or device at a time. The ring-style charging cases are size-specific to a particular wearable.

Ring charging cases explicitly state a USB-C cable is not included. The OEM-style charger lists a 3-foot cord/cable in its product details.

Charging cases advertise up to about a month of battery life — roughly 30 days — from a single charge.

Weights reported span from about 2.12 ounces for the ring charging cases up to about 1.23 pounds for the OEM-style charger.
