Overview
Lost your smart ring charger? This universal magnetic charger cable works with most major smart rings. $12.99 for a 2-pack — cheap insurance for travelers.
Why You Need a Spare Charger
Smart ring chargers are small, proprietary, and easy to lose. If you lose your charger, you're looking at $30+ for a replacement from the manufacturer — and 1–2 weeks of shipping time without sleep tracking.
This universal charger is a cheap insurance policy. Keep one in your travel bag, one at the office, and you'll never be without sleep tracking. The 2-pack at $12.99 ($6.50 per charger) is significantly cheaper than manufacturer replacements.
Compatibility Notes
The universal charger uses a magnetic charging system that works with most major smart rings, but compatibility isn't guaranteed for every model:
- Oura Ring 4: Works, but charging is slower than the official dock
- RingConn Gen 2: Works at full speed (RingConn uses a standard magnetic charger)
- Samsung Galaxy Ring: Works at full speed
- Ultrahuman Ring Air: Works, but may require positioning adjustments
If compatibility is critical, we recommend buying the official manufacturer charger. For travel spares, this universal charger is fine.

Generally yes, with caveats. Third-party chargers deliver the same voltage as official chargers, so they won't damage your ring's battery. However, charging speeds may be slower, and the magnet may not hold the ring as securely. For daily use, stick with the official charger. For travel spares, third-party chargers are fine.
