Magnetic Charger for Fitbit Versa 4 and Sense 2

This internal power cable provides a magnetic charging dock designed specifically for Fitbit Versa 4, Versa 3, Sense and Sense 2 smartwatches. It connects via USB to a power source or computer for charging and data sync. The compact cradle suits users who need a reliable replacement or spare cable for home, office or travel use.

Capacity and Headroom

The adapter delivers standard USB charging current suitable for the supported watch models. It handles daily top-ups and overnight charging without issue. The cable does not support fast-charging protocols beyond the watch's own specification. Data transfer speed is limited to the USB 2.0 interface and the watch's sync capability.

Thermals Noise and Power Draw

The plastic housing remains cool during normal charging cycles. No active cooling is present so operation is completely silent. Power draw matches the watch's low charging requirement and adds minimal load to a USB port. The 6.3 cm square dock sits stably on a desk or nightstand.
