In this review the reviewer looks at the Smart Ring Charging Size 11, a compact USB-C fast charging dock designed specifically for Oura Ring Gen3 Horizon and Heritage rings. The bottom line: it is for Oura Gen3 owners who want a reliable, small travel-ready charger that charges quickly and protects the ring battery. The reviewer found the charger simple to use, with fast charging times and multiple safety protections that make it a sensible accessory for daily use and travel.

Key Features

• Compatibility: Designed to fit Oura Ring Gen3 Horizon and Heritage models, offering a charger matched to the ring's shape for consistent contact.
• Size-specific fit: The Size 11 dock is made to the ring size so the ring sits securely and charges without slipping, improving charging reliability.
• Fast charging: Charges a ring in approximately 30-80 minutes depending on battery level, which can provide up to a week of continuous use from a single charge.
• Safe charging: Built-in protections include short-circuit, over-voltage, and over-current safeguards to reduce risk while charging.
• Portable design: The compact, lightweight charger and USB-C cable are easy to carry for travel, office, or in a bag during daily use.
• User-friendly placement: A simple dock layout helps position the ring correctly so charging starts reliably every time.

Who It's For

The Smart Ring Charging Size 11 is best for Oura Ring Gen3 owners who need a second charger for travel, a compact replacement charger, or a dedicated dock to keep at work. It suits people who value quick top-ups and a charger that fits the ring snugly so charging is consistent.

It is not for users who do not own Oura Ring Gen3 Horizon or Heritage rings or who need a charger that supports multiple ring sizes in a single unit, since each charger is made to a specific ring size and does not include interchangeable adapters.
