OURA Ring 4 Charger – Size 11 USB-C Dock, Fast Charge (Up to 8 Days Use)

Charge smarter with the official OURA Ring 4 Charger

The OURA Ring 4 Charger is the dedicated charging dock designed specifically for OURA Ring 4. It provides a clean, simple, one-piece charging experience that helps you keep your ring ready for daily use. The dock is size-specific, so you can trust a snug fit that aligns perfectly with your ring’s charging contacts, reducing the chance of misalignment and ensuring a stable connection when you set the ring down.

Size-specific fit you can depend on

Each OURA Ring 4 has an inside size printed on the ring itself. The charger follows the same size specificity, which helps minimize wobble and helps you know you’re connecting the right cradle for your ring. It’s a small but meaningful detail for a consistent charging experience.

• Precise alignment for efficient charging every time
• Size-aware design reduces misfit and wobble

Fast charging to fit your day

Charging time varies with the ring’s current battery level, but most users report a full top-up in roughly 20 to 80 minutes. That range makes it practical to top up between activities or let the ring charge while you take a break or sleep.

• 20–80 minute full charge depending on current level
• Quick top-ups help you stay ready for activities

Track charge status at a glance

Open the OURA app and tap the circular battery icon in the home tab to see the current charge. A quick check helps you plan charging around your day without guessing when to reconnect.

• Battery status available in the OURA app
• Simple, at-a-glance planning for charging sessions

Safety and compatibility

The USB-C to USB-C cable is intended to be powered by an external 5V supply that complies with IEC 62368-1. This standard-friendly setup supports safe operation in home or office environments.

• IEC 62368-1 compliant power supply guidance
• USB-C to USB-C cable included for straightforward use

Note: the OURA Ring 4 itself can last up to 8 days on a single charge depending on usage, and the charger is designed to support regular top-ups to keep your ring ready. This is an official accessory built to align with your daily routines without adding clutter.
