1. Compact Router Design (Desktop-Friendly + Easy to Place)

　　1. Mini Compact Appearance and Materials

　　Ultra-Small Design:

　　The device measures only 65 × 35 × 25 mm (length × width × height), with a volume of approximately 57 cm³ (equivalent to the size of an egg) and weighs ≤ 80 g. It can be placed directly under the router (most routers reserve a space of ≥ 70 × 40 mm at the bottom) or in a corner of the desktop, eliminating the need for additional wiring. It is suitable for compact environments such as living rooms, studies, and office workstations.

　　Home-Friendly Materials:

　　The housing is made of UL94 V-0 flame-retardant ABS (2 mm thick, ensuring both lightness and durability). It is sprayed with a matte non-slip coating (friction coefficient ≥ 0.6) to prevent slipping from minor desktop bumps. Available in off-white and dark gray (matching the appearance of mainstream routers), it blends seamlessly into any home or office environment without creating an unobtrusive industrial feel.

　　2. Indoor Protection and Cabling Adaptation

　　Basic Protection and Quietness:

　　With an IP20 protection rating (dustproof and finger-proof), it's suitable for dry indoor environments (such as desktops and bookshelves), eliminating the need to worry about dust accumulation affecting performance. It utilizes an aluminum micro-heat sink with natural convection (heat sink area ≥ 8 cm²) for heat dissipation, a fanless design, and operates with a noise level ≤ 8dB (close to ambient noise), making it suitable for quiet environments like bedrooms and studies.

　　Router-Specific Cabling:

　　It comes standard with a 1.8-meter pure copper DC output cable (0.5 mm² diameter, flexible and easy to bend). One end features a 5.5×2.1mm universal DC plug (compatible with over 95% of home router interfaces, such as TP-Link, Huawei, and Xiaomi routers), while the other end features a lock-on design (prevents detachment after inserting the adapter). The input cable is a 1.2-meter two-core pluggable power cable, making it easy to swap cables of different lengths to fit different outlet locations.

　　II. Core Performance (Stable Power Supply + CE Compliance)

　　1. 9V 1.5A Precision Output and Network Adaptation

　　Power and Voltage Stability:

　　The input is compatible with a wide range of 100-240V AC voltage (compatible with domestic and international power grids, suitable for travel), and the output is 9V DC constant voltage + 1.5A constant current (rated power 13.5W). Voltage accuracy is ±1% (output fluctuation ≤0.09V when the load varies from 0.3A to 1.5A), fully meeting the power requirements of home routers (most wireless routers consume 5-12W, and can stably drive networks including mesh routers).

　　Low ripple ensures network stability:

　　The three-stage filtering (capacitor + inductor + LDO voltage regulation) design ensures output ripple ≤ 3mVp-p (far below the 10mVp-p upper limit required for router power supply). This prevents ripple interference with the router's RF module, preventing WiFi signal lag and packet loss. A ripple rejection ratio of ≥ 65dB (at 50Hz/60Hz power frequency) ensures clean power supply and stable network latency even when used near appliances like refrigerators and air conditioners (measured latency fluctuation ≤ 2ms).

　　2. CE Certification Compliance and Multiple Protections

　　Full CE Compliance Enhancement:

　　Complies with the EU EN 55022 Class B electromagnetic compatibility standard (radiated disturbance ≤ 40dBμV/m, conducted disturbance ≤ 54dBμV), and passes the EN 60950-1 standard for the safety of information technology equipment (creepage distance ≥ 3mm, clearance ≥ 2.5mm). The certification report includes 12 test items, including "electromagnetic radiation, temperature rise, and withstand voltage." This product can be directly used for sales in the EU market or in domestic scenarios with compliance requirements (such as corporate office procurement).

　　Exclusive Router Security Protections:

　　Built-in quad-layer protection: short circuit, overvoltage, overcurrent, and overheating, enabling unattended operation of the router:

　　Short-circuit protection: When an output short circuit occurs, the current is limited to ≤2A within 15ms and automatically recovers after the fault is resolved (no need to manually plug and unplug the power cord, avoiding the need to restart the router after a network interruption).

　　Overvoltage protection: Automatically limits the output voltage when the output voltage ≥9.9V to prevent breakdown of the router's motherboard capacitors.

　　Overcurrent protection: Gradually reduces the output when the load current ≥1.65A to prevent overloading multiple devices in a mesh network.

　　Overheat protection: Triggered when the internal temperature ≥80°C (such as in a sealed router box in summer) and automatically recovers when the temperature drops to 65°C to prevent adapter aging.

　　III. Wireless Router Applications (Full Home/Office Coverage)

　　1. Core Scenario: Single Router Power Supply

　　Home Desktop Router:

　　Compatible with home wireless routers with up to four antennas (such as the AX3000). Its compact 65×35mm size allows it to be placed directly next to the router. The 1.8m cable is long enough to reach from a desktop outlet to the router, eliminating strain. Its low-ripple output ensures stable WiFi 6 signal speeds (download speed fluctuations of ≤5Mbps at 500Mbps bandwidth) and eliminates signal disconnections due to power instability.

　　Office Wall-Mount Router:

　　When used with a router wall-mount bracket, the adapter can be attached to the bracket with double-sided tape (lightweight and durable). The 1.2m input cable can be hidden in a wall trough, keeping the office space tidy. CE compliance meets enterprise IT equipment procurement standards, preventing electromagnetic interference from other office equipment (such as computers and printers).

　　2. Extended Scenario: Router Networking and Auxiliary Power Supply

　　Mesh Sub-Router Networking:

　　A single adapter can power one main router and one mesh sub-router (total power ≤ 13W). A DC splitter enables "multiple power supplies from one device," making it suitable for mesh networking needs in large apartments. This eliminates the need for separate adapters for each sub-router, reducing socket usage. The 1.8-meter cable allows for flexible placement of the sub-routers (e.g., a main router in the living room and a sub-router in the bedroom, allowing the cable to be routed around corners).

　　Powering External Router Devices:

　　Compatible with low-power devices connected to the router, such as mini USB fans (power ≤ 2W) and low-power smart sensors (power ≤ 1W) connected to the router's USB port. The 9V 1.5A power reserve can stably power the "router + external device" combination, eliminating the need for additional power supplies and simplifying desktop wiring.

　　IV. Maintenance and Usage Guarantee (Low Maintenance + Quiet)

　　1. Low Maintenance Design for Desktop Scenario

　　Status Visualization and Easy Operation:

　　Equipped with a single-color LED indicator (blue = normal output, off = fault/no power), you can quickly determine the power status without specialized tools (e.g., if the router is disconnected from the internet, first check the adapter indicator to see if it's normal to rule out power issues). Both input and output cables are pluggable, allowing cable replacement in 30 seconds or less (if a cable is damaged, simply replace it without discarding the entire device).

　　Quiet and Long Life:

　　The fanless, natural heat dissipation design ensures silent operation, making it suitable for bedrooms (where it won't disturb your sleep) and study rooms (where it won't affect your work concentration). Equipped with 105°C high-temperature-resistant electrolytic capacitors (lifespan ≥8,000 hours) and oxygen-free copper coils, the device boasts an MTBF (mean time between failures) of ≥60,000 hours under full load, equivalent to over 9 years of stable operation in an 18-hour daily household environment.

　　2. CE Compliance Details and After-Sales Service
