The rumored Ultrahuman “Pro Charger” is now the PRO Charging Case, announced alongside Ring PRO on February 27, 2026. Ultrahuman says the magnetic case can charge Ring PRO on the go, store ring data, and help locate the case; its U.S. purchase page checked October 4, 2026 lists it with Ring PRO and says shipments begin October 10.
Those features and battery figures are manufacturer claims, not independently verified test results. Ultrahuman’s reviewed materials do not establish whether the case works with Ring AIR or whether it is sold separately.
What is the Ultrahuman Pro Charger?
Ultrahuman calls the accessory the PRO Charging Case. It is designed for Ring PRO and uses the company’s UltraSnap magnetic charging technology: the ring clicks magnetically into the case. Ultrahuman also describes case features for storing ring data, finding the case, and connecting directly for firmware updates, diagnostics, and troubleshooting.
| Feature | What Ultrahuman says |
|---|---|
| Ring connection | UltraSnap magnetic charging; Ring PRO clicks into the case. |
| Case battery | Up to 45 days of case battery life. |
| Data storage | Up to one year of Ring PRO data storage on the case. |
| Finding the case | Integrated speaker and app proximity guidance for Find My Case. |
| Other features | Haptic confirmations, an LED battery indicator, and direct connectivity for firmware updates, diagnostics, and troubleshooting. |
| Recharging the case | Qi wireless charging; the U.S. purchase page also lists a USB-C cable in the box. |
The battery-life and storage figures above are Ultrahuman’s claims. The research reviewed did not establish independent test results for them.

What was known before the launch?
A February 18, 2026 Wareable report described an FCC filing that appeared to show a multifunction charging case for a rumored Ring Pro. The report mentioned an apparent 400 mAh battery in filing imagery, but that was a pre-launch report, not a confirmed current product specification. At the time, price, release timing, and whether the case would be bundled or sold separately were unresolved. Ultrahuman later announced Ring PRO and the case on February 27.
What remains unclear
- Ring AIR compatibility: The reviewed official materials do not say whether the PRO Charging Case charges Ring AIR.
- Separate purchase: The current U.S. page lists the case with Ring PRO, but does not establish that it is available separately.
- Independent performance: The reviewed sources contain no independent measurements confirming the case’s advertised battery life or storage capacity.
