Multi-Size Compatibility: Works with Ou-ra Ring 4 sizes 7 to 13 - perfect for couples or families with different ring sizes. Spring-loaded design automatically adapts to fit your ring. Just align the groove with the front indicator, press down, and it locks in place. Not for Gen 3/5. Charging Speed: reaches 80% in about 45 minutes, with a full charge in roughly 2 hours (final 20% uses trickle charging to protect battery health). LED pulses while charging; check the Ou-ra App to see when it's fully topped off.
Spring-Loaded Retractable Design: Spring-loaded prongs flex to securely hold any size 7-13 ring. The snap-on fit stays firmly in place - no slipping or constant adjustment needed. Yet it lifts off easily when charging is complete. No fiddling, just drop and charge. Compact & Travel-Ready: Fits right into your pocket, purse, or travel bag. A true travel lifesaver when you don't want to pack multiple chargers. Works with any USB-C power source you already own. USB-C cable included.
