How fast will my Oura Ring Gen 4 charge on this dock?

The RXYKEJI dock reaches about 80% battery in roughly 45 minutes under typical charging conditions. Charge times will depend on the power source and ring battery state, but the design emphasizes quicker top-up charging for daily use.

• Approximately 80% charge in ~45 minutes
• Optimized for daily quick charges rather than long overnight cycles
• Monitored by your Oura app battery indicator for exact status

Will this charger fit my ring size and model?

The dock is made to fit Oura Ring Gen 4 in sizes 7 through 13 using an adjustable, retractable cradle. It will not work with Oura Gen 3 rings or non-Oura smart rings, so confirm the model and size engraved inside your ring before buying.

• Compatible only with Oura Ring Gen 4
• Fits sizes 7, 8, 9, 10, 11, 12, and 13
• Check the size printed inside your ring to ensure compatibility

• Built-in over-current protection prevents excessive current draw
• Over-voltage, short-circuit, and over-temperature protections included
• Small, lightweight footprint and 3.3 ft USB-C cable for travel convenience

What comes in the box and where does this charger work best?

The package is intentionally minimal to keep the charger compact and portable. It works well at a desk, nightstand, office, or packed in luggage for trips.

• Includes: 1x RXYKEJI charger dock, 1x 3.3 ft USB-C cable, 1x user manual

Who is this for: This charging dock is aimed at Oura Ring Gen 4 owners who want a single, compact charger that serves multiple ring sizes and moves easily between home, office, and travel. Choose this dock if you need faster top-up charging, multi-size compatibility (7–13), and built-in electrical protections — but do not buy it if you have an Oura Gen 3 or non-Oura ring.
