This Oura Ring 4 charger has been absolutely perfect for keeping my size 11 ring powered up without any hassle. The charging dock design is incredibly user-friendly - just drop the ring in place and it connects immediately with a satisfying magnetic snap. No fumbling around trying to align charging contacts like with some other wearables. The USB-C cable is a major upgrade from older charging systems. It's convenient since I can use the same cable type for multiple devices, and the connection feels secure and durable. The cable length is just right for bedside charging or desk use without being unnecessarily long. What impressed me most is the charging speed and efficiency. My ring consistently charges up to 8 days of battery life in about an hour, which means I barely notice any downtime. I usually charge it while I'm showering or having morning coffee, and it's ready to go for over a week of continuous health tracking. The size 11 fit is precise - no wobbling or loose connection issues that could interrupt charging. The dock itself has a nice weight to it and doesn't slide around on smooth surfaces. The minimalist design looks clean on my nightstand and doesn't take up much space. Build quality feels premium throughout. After several months of daily use, everything still works like new. The magnetic connection remains strong, and there's been zero degradation in charging performance. This charger makes owning an Oura Ring 4 completely seamless. Fast, reliable, and well-designed - exactly what you need to keep your health tracking uninterrupted. Highly recommended for any Oura Ring 4 owner! ... show more

    • Reliable Charger That Works as It Should
Style: Standard Size: 13
I picked up this charger for my ring and it’s worked perfectly so far. The fit is secure and the ring charges consistently without needing to be adjusted. It feels well made and does exactly what it’s supposed to do with no hassle. Having a dependable extra charger is really convenient for travel or keeping one at a second location. Overall, it’s been a solid, no-issues experience. .

    • Be aware.... Oura is a potential money pit
Style: Standard Size: 8
The charger worked well BUT it's USB-C port that does NOT come with a charging block so that may be an added expense to you. Also, the app for the ring costs $6 monthly and you cannot even access the most basic functions without a subscription. That being said the ring does pick up on sleep apnea episodes but considering the ring can only fit certain sized fingers and hence is difficult to share or move around if it becomes irritating, it gets in the way of washing hands or wearing gloves, and even used it's MUCH more expensive than my Inspire 3, I'm giving it up and keeping to my watch fitness tracker. But it's a decent piece of equipment if you can afford the initial costs and subscription, and don't mind wearing a thick ring. ... show more

    • Why so expensive?
Style: Standard Size: 9
The charger looks nice and does the job. I took off one star because it’s very expensive for such a small, uncomplicated item.
