Oura announced last week that its long-awaited charging case is finally shipping. I got one to try out, and can confirm that it works well and is arguably better designed than those of its competitors. That said, is it really worth $99?
The charging case works with the Oura Ring 4, not the older models like the gen 3. I’ve previously reviewed the Oura Ring 4, and it’s probably the best smart ring out there right now. You pay a premium for it, though—not only are Oura’s prices higher than many of its competitors ($349 to $499), Oura also requires a $5.99/month subscription to access nearly all of its features.
The standard charger that ships with any of the Oura rings is a simple flat square with a post that the ring fits onto. (The square base then plugs into a USB-C cord.) This works fine, but it’s inconvenient to travel with, and also susceptible to jostling. Maybe you never bump things around on your nightstand, or snag a charging cable, but it’s certainly happened to me.
Like other Oura users, I’ve been wishing for a charging case. RingConn and Luna Ring both come with cases, so it would be nice if Oura would catch up. I usually keep my ring in my gym bag during weightlifting workouts (since it’s neither comfortable nor useful in those workouts). I plan to keep the charging case in my gym bag and use it during workouts.

Oura says the case holds enough power for five full charges of the ring, and it takes up to 80 minutes to charge the ring (less if the ring is partially charged, obviously). The case itself charges in 90 minutes.
I haven’t been able to test the case in the long term, since I just got it, but the ring has a battery life of five days or more depending on the size of the ring and the settings you have enabled. That means you could go about a month without charging from a cable.
The case is sized to your ring, so you have to make sure to buy the correct size of charging case—for example, a size 8 case for a size 8 ring.
There’s a colored LED on the front of the charging case. When a ring is inside and charging, a white LED will pulse, just like the nightstand charger does. When the case is empty and open, it will indicate the case’s charge level. Green means the battery is full. The case pairs to your Oura app, so you can check the app to see the charge level of both your ring and the case.
How it compares to other brands

I happen to have a Luna Ring and a RingConn gen 2, which both ship with a charging case. Luna’s case holds about 30 days of charge, similar to Oura’s, while RingConn says its case can hold 150 days of charge.
The other noticeable difference is size. RingConn’s case is the largest of the three, which probably explains its longer battery life. Oura’s case is slightly wider than Luna’s, but slimmer. You can see the size differences in my photos here.

RingConn’s case comes with the ring, and costs $299 for the package. Luna charges $329 for a ring plus charging case. (I recall Luna’s charging case being optional, and available for an extra $49, as I wrote here, but right now I can only find the package deal on their site.) Oura’s charging case is sold separately, for $99, so you’d spend $448 to $598 for the ring plus the case.
