CXAKDBFA S16 USB-C Charger for Oura Ring Gen 4

The CXAKDBFA S16 is a dedicated charging accessory built for the Oura Ring Gen 4 in sizes 7 to 13. It connects to any USB-C power source you already own and comes with a USB-C cable in the box. The unit weighs 34 grams and measures 3.4036 cm by 8.7884 cm by 8.89 cm.

Spring-loaded adapter and LED pulse indicator

A spring-loaded groove automatically adapts to each ring size so the ring locks in place without slipping. The LED pulses while charging and stops when the battery reaches 80% in about 45 minutes; a full charge takes roughly 2 hours with trickle charging for the final 20%. Built-in over-current, over-voltage, short-circuit and over-temperature protection guards the ring during every session.

Drop-in alignment with any USB-C port

Align the groove with the front indicator, press down, and the charger snaps on securely. It lifts off easily when charging is complete. The 90-degree connector keeps the cable close to the surface for desk, nightstand or travel use. This model is not compatible with Gen 3 or Gen 5 rings.

Questions about this item

Will the spring-loaded prongs on the S16 charger wear out and need replacing after repeated daily use?

The spring-loaded design is built to hold ring sizes 7 to 13 securely and lift off easily; no user-replaceable parts are mentioned for the prongs or the USB-C cable.

What is the first limit reached when the charger runs continuously for hours?

Built-in over-current, over-voltage, short-circuit and over-temperature protection will activate before any component reaches a hard thermal or electrical limit.

How much heat or noise does the S16 produce when left plugged in all day?

The charger draws 0.1 amps at 5 volts, so heat output is minimal; it has no fan and the LED indicator pulses silently while charging.
