The phrase "roku 3 power adapter" represents a mature but steady aftermarket segment driven by the longevity of the Roku 3 hardware (Model 4230X) and the frequent failure of its original power supplies. While newer Roku models have shifted toward USB-powered designs, the Roku 3's unique 12V requirement sustains a specific demand for replacement barrel-jack adapters.

📊 Market & Consumer Insights

* Stable Replacement Demand: Consumer feedback highlights that the Roku 3 is often "built to last," but its power adapter is the weak link. A common failure point is internal capacitor degradation, leading to complete power loss or erratic device behavior. Reddit Reddit

* Unique Power Specs: Unlike modern streaming sticks that use 5V USB power, the Roku 3 requires a 12V 1A (center-positive) DC output. Many users mistakenly attempt to power it via a TV's USB port, resulting in failure and driving search volume for dedicated replacements. Justanswer Reddit

* Search Trends: Keyword data shows significant monthly interest in "roku power cord" (~1,000+ exact searches/mo) and "roku power adapter" (~800+ exact searches/mo). The high "ease of ranking" score (100) indicates a low-competition niche for aftermarket sellers. Roku

* Regional Dynamics: US models are often dual-voltage (100-240V) but ship with US Type A/B prongs. Significant demand exists in Australia and New Zealand for local Type I plug variants or 240V-compatible travel adapters. Geekzone Reddit

🔌 Sourcing & Product Analysis
