Two rechargeable batteries with magnetic connectors.
- 1.5–3 hours of warmth per battery depending on your chosen temperature.
- Universal use — each battery fits both tummy and back zones, so you never have to guess which one goes where.
- Direct control on the battery — adjust temperature or switch off without using the app.
- Long lifespan — at least 400 charging cycles without capacity loss (that’s about 1,200 hours of heating, or roughly 4–5 years of normal use).
