What powers each part of a couples vibrator?
Identify battery types, charger connectors and what ships in the box.
Start with a parts list
Write down each powered piece, including any separate bullet, remote or charging case. For the Intense kit, the ring and bullet use different battery types. For a rechargeable model, record the connector and ask whether the cable is included.
Separate charge time and runtime
The Royale listing states a charging time and two runtime estimates at different settings. Double Diver publishes a charge estimate. Keep those labels attached to each figure. Check the model and charger instructions before using a replacement cable.
Read the model-specific controls
Check what the button does from off, how it stops and whether it recalls the last mode. A mode count cannot answer those questions. For situations where two people share control, see the shared controls guide.
