Key features and specs that matter

Designed for oura ring 4 size 10

This charger is built for Oura Ring 4 and is size-specific. Your ring size is typically indicated on the inside of the ring, so check that before purchasing a replacement or extra dock.

Charging time you can plan around

Oura Ring 4 typically charges fully in about 20 to 80 minutes, depending on where the battery starts. That range can make it easier to top up during a routine, such as morning or evening, rather than needing long charging sessions.

USB-C cable with 5V power requirement

The included USB-C to USB-C cable is intended to be supplied by an external 5V DC power source that complies with IEC 62368-1. In practical terms, you’ll want to use a suitable USB charger or power adapter that delivers the expected 5V output.

Who this charger is best for

• People with Oura Ring 4 size 10 who need a replacement or extra charging dock.
• Buyers who want simple, repeatable charging at a desk or nightstand, thanks to the dock-and-magnetic style connection.

Who should avoid it (or double-check first)

• If your ring is not size 10, you’ll likely run into fit issues. This charger is specifically intended for the correct ring size.
