The leaked database filing gives us our first details of a key accessory for the rumored Ring Pro
Ultrahuman is preparing to launch a major upgrade to its smart ring lineup: a charging case.
That’s if an FCC filing first spied by Wareable is anything to go by—one which suggests the Indian brand is preparing “a multi-functional charging case designed specifically for the Ultrahuman Ring Pro”.
As with all FCC database applications, much of the information here relates to the device’s communication specifications. However, it adds substantial weight to the idea that the brand’s Ring Pro—which first leaked in November—will arrive in the coming months.
The fact that the ‘Pro Charger’ is specifically designed for the upcoming smart ring, with no mention of support for the existing Ultrahuman Ring Air, also suggests the device will feature a significant redesign.
This redesign is expected to enable the brand to re-enter the US market, too, where its Ring Air currently faces an import ban following a patent-infringement ruling.
Details from the ‘Pro Charger’ filing
As we say, there’s not much in the way of juicy details available from this latest listing. The most illuminating comes from the image below, which suggests the case will be a square shape and feature a 400 mAh battery capacity.

While Oura’s Ring 4 charging case capacity isn’t listed, this should give Ultrahuman’s equivalent the heft to power multiple recharging cycles of the ring on a single charge.

The filing also confirms some technical basics: the Ring Pro will use Bluetooth Low Energy (BLE), operate in the 2402–2480 MHz range, and has a neat little 2.4GHz RF ceramic chip antenna built with LTCC tech.
It will also be built from a combination of tough materials–titanium, epoxy resin, and polycarbonate.
When will we see the Ultrahuman Ring Pro (and Pro Charger)?
FCC documents indicate that the Ring Pro was tested in November 2025, and manufacturing began soon after. And once the FCC grants final approval, these devices are typically cleared for US sales.

The confidentiality period for the filings also ends in May 2026, which is a strong hint that an official launch announcement will occur before then.
We don’t have exact prices or release dates yet, naturally. And the big question—whether it will be sold separately (like Oura’s case) or included with the Ring Pro—remains unanswered.
However, either way, adding a dedicated charging case could help the brand keep up with market leader Oura as it seeks to re-enter the US market.
