Starlink Gen 3 Power Adapter (V3)
The Starlink Gen 3 Power Adapter, also known as the Standard Power Supply, is the official AC-to-DC power supply unit included with the Starlink Gen 3 Router and Standard Kit. Introduced in late 2023, it powers the Gen 3 Router, which in turn supplies power over Ethernet (PoE) to the Starlink Dish V4 (Gen 3 flat dish). This setup differs from the Gen 2, where the router had built-in PoE injection—Gen 3 requires the separate Advanced Power Supply for direct dish powering without the router. As of September 2025, it’s widely available and praised for its efficiency in residential and mobile setups.
Key Features
- Electrical Specifications: AC input: 100-240V, 50/60Hz, up to 5.0A; DC output: 57V, 3.42A (195W max). This provides stable power for the router and dish, supporting peak loads like snow melt on the dish (up to 150-200W draw).
- Cables Included: 15 m (49.2 ft) proprietary Starlink cable from dish to router; 1.5 m (4.92 ft) AC power cord; 1.5 m (4.92 ft) DC output cable to the router.
- Design and Durability: Compact “power brick” design (dimensions approx. 6 x 3 x 1.5 inches; weight ~1 lb). Features over-voltage, over-current, short-circuit, and thermal protection for safety. Operates in temperatures from -22°F to 122°F (-30°C to 50°C), suitable for indoor use with some outdoor tolerance.
- Efficiency: Idle draw around 10-15W; full operation 50-100W, making it more efficient than running through an inverter for DC setups.
- Compatibility: Exclusive to Starlink Gen 3 Router and Dish V4. Not compatible with Gen 2 or earlier kits, Mini dish, or High-Performance dishes without adapters. Can pair with third-party DC converters for 12V/24V vehicle or RV use.
Performance and User Feedback
The adapter delivers reliable power with minimal voltage drop, supporting download speeds up to 300 Mbps and handling surges during dish heating. Users on Reddit report it runs cooler than Gen 2 equivalents and pairs well with mesh nodes, but some note the 15 m cable limit requires extensions for larger setups. In mobile scenarios (RVs, boats), it draws 4-5A at 12V via converters, but Starlink recommends 30A circuits for peak performance. Recent X posts highlight its addition to the official shop alongside Mini adapters, with users appreciating no-drill mounting kits for clean installs. Compared to third-party options, the official unit is more reliable but bulkier.
Alternatives and Accessories
- DC Power Options: For off-grid/vehicle use, third-party 12V adapters (e.g., Vanlife Outfitters or Trio Flatmount) convert 10-36V to 57V/4.5A, reducing inverter waste by 30-50W. Official Gen 3 DC supply now available via Starlink Shop (requires 30A fuse).
- Mounting Kits: Wall mounts for router + power supply for tidy setups.
- Extensions: Shielded Ethernet cables for longer runs without signal loss.
