What the 3C listings reveal about Samsung’s next smartwatches
Samsung Galaxy Watch 9 certification refers to newly published regulatory listings that confirm model numbers, charging specifications, and compatible chargers for Samsung’s upcoming smartwatches before they are officially announced. In this case, two unreleased wearables with model numbers SM-L3550 and SM-L7150 have appeared in the Chinese 3C certification database, widely understood to correspond to the Galaxy Watch 9 and Watch Ultra 2. The entries confirm support for 10W charging at 5V/2A, mirroring the capabilities of the Galaxy Watch 8 and the first Watch Ultra. According to Android Authority, both watches “are listed with 10W charging support (5V/2A), matching the charging speeds offered by their predecessors.” While the 3C database does not reveal names, colors, or design changes, it does set firm expectations around smartwatch charging technology and suggests Samsung is locking down key hardware decisions ahead of its next Galaxy Unpacked event.
Charging technology: Same 10W power, same EP-T1510 charger
The most concrete insight from the 3C certification approval concerns smartwatch charging technology. Both SM-L3550 (expected Galaxy Watch 9) and SM-L7150 (likely Watch Ultra 2) are rated for 10W charging and listed as compatible with Samsung’s EP-T1510 travel charger. The Tech Outlook notes that “this same travel charger model number was also seen with the Galaxy Watch 8 and Galaxy Watch Ultra models, meaning that there may not be any change in the charging department this time.” For users, this points to continuity rather than a leap forward: owners of recent Galaxy Watches should be able to reuse existing chargers, and charging times will probably remain similar generation to generation. The lack of higher wattage or new charger references also hints that any battery life gains this cycle will need to come from larger batteries or improved efficiency, not faster wired charging.
Why 3C certification matters for global launch timing
3C certification approval is more than paperwork; it is a key timing signal for Samsung’s broader launch plans. Devices typically pass through such regulatory databases in the weeks or months before retail availability, once core hardware—such as charging circuitry and supported adapters—is final. The fresh listings for the Galaxy Watch 9 and Watch Ultra 2 align with reports that Samsung is preparing its next Galaxy Unpacked event on July 22, where new foldables are also expected. While the database does not confirm that date, the appearance of multiple wearables at once suggests Samsung is in the last stages before announcement. Because 3C is a prerequisite for selling electronics powered by external chargers, clearance there is also an important step toward a synchronized global rollout of these smartwatches, alongside approvals from other regional regulators.
What the certifications hint at beyond charging
Beyond power specs, the Galaxy Watch 9 certification gives early hints about Samsung’s product stack. The presence of the SM-L3550 and SM-L7150 model numbers alongside reports of a Galaxy Watch 9 Classic suggests a multi-tier lineup that again separates a standard, a more traditional, and an ultra-grade model. The Tech Outlook reports that the Classic version is also expected to adopt the same 10W charging support, signaling consistent baseline hardware across the range. That uniformity may simplify accessory compatibility and software optimization while leaving differentiation to design, sensors, battery size, and durability. Since regulatory documents focus on safety and power, they stop short of confirming health features or materials, but they do confirm that Samsung is not experimenting with experimental high-wattage charging on the wrists of users—favoring steady, known technology over headline-grabbing charge speeds.
What to expect next before Galaxy Unpacked
With 3C entries live, the next steps are likely to be a series of additional regulatory sightings and leaks that fill in the remaining hardware and software details. Android Authority highlights that other Samsung products, including a Galaxy A27 handset, are also surfacing in certification databases, reinforcing the sense that the company is entering a coordinated launch window. Rumors point to July 22, 2026 for the next Galaxy Unpacked, where the Galaxy Watch 9, Watch Ultra 2, and Watch 9 Classic are expected to appear alongside foldable phones. Until Samsung speaks publicly, details like sensors, display sizes, and materials remain unconfirmed. Still, the confirmed 10W charging, EP-T1510 compatibility, and locked-in model numbers give a reliable baseline: this generation is about refining the platform and ecosystem rather than rewriting smartwatch charging technology.
