I. Home-Friendly Appearance and Portable Storage Design

　　1. Compact Form Factor Compatible with Home Spaces

　　Compact Structure: Featuring a simple, square design, it measures approximately 320 × 200 × 250 mm (equivalent to the size of 1.5 rice cookers) and weighs ≤12 kg. A 35 mm diameter, non-slip handle on the top allows women and the elderly to carry it single-handed to balconies, storage rooms, or living rooms, making it ideal for limited storage spaces (such as closet corners and balcony cabinets). The exterior is constructed of a food-grade ABS + flame-retardant PC composite material (compliant with GB 4943.1-2011). The matte finish resists fingerprints, exhibits no yellowing over time, and exhibits no noticeable deformation after accidental impact. Simple Operation Interface: The front panel features a 4.3-inch high-definition LCD screen, displaying only four core information items: remaining battery (1% accuracy), current power, charging mode, and battery temperature, eliminating the need for complex parameters. Three physical buttons (Master Control/AC Output/Emergency Lighting) are located below. These raised buttons allow for blind pressing during power outages and low light conditions, and provide clear feedback (press force 500±50g). 2. Compatible with Home Charging Methods

　　Multi-Scenario Charging Design:

　　Mains Fast Charging: Supports 600W high-power mains charging, charging from 20% to full in just 1.5 hours (compatible with household 10A/16A outlets, no circuit modification required). The indicator light on the side of the battery flashes in a continuous stream during charging, and the battery automatically shuts off when fully charged to prevent overcharging.

　　Portable Solar Charging: Compatible with a 200W foldable monocrystalline silicon solar panel (unfolded dimensions: 1400×700×50mm, folded dimensions: 350×200×100mm, weight ≤3kg). Connects via an MC4 quick-connect connector. Charging power is stable at 180-190W when the sunlight intensity is ≥600W/m², and a full charge can be achieved in 6 hours (ideal for outdoor charging during extended power outages).

　　Emergency Car Charging: Equipped with a 12V/24V car charging cable, the car's cigarette lighter charges at 100W, and a full charge can be achieved in 4 hours. 50% (In the event of a power outage, you can drive to a nearby charging station to recharge).

　　Storage Details: Both the charging cable (mains/car charger) and the solar panel cable are designed to be retractable and can be wrapped around the hidden cable clip on the back of the device to reduce cable clutter. The solar panel can be folded and placed in a dedicated Oxford cloth storage bag, which can be placed in the balcony cabinet with the power supply, eliminating extra space. II. Core Performance and Home Backup Power Adaptability

　　1. Power and Device Compatibility

　　Output Capacity: The built-in pure sine wave inverter delivers a continuous output power of 1000W and a peak power of 2000W, capable of stably powering over 90% of commonly used household devices:

　　Critical Emergency Equipment: 150W household refrigerator (daily power consumption 3-4kWh), 80W medical oxygen concentrator (low-flow mode), 10W router + 5W optical modem (maintaining network communication), 20W LED ceiling light (whole-house lighting);

　　Life Support Equipment: 600W electric skillet (boiling water/heating rice), 300W small oven (heating food), 60W laptop (remote working). Voltage fluctuation after connection is ≤ 2V, with no device errors (e.g., the refrigerator compressor starts without lag, and the router remains online). Battery Life Test: Built-in 1000Wh lithium iron phosphate battery (256,000mAh, nominal voltage 3.7V), charge and discharge efficiency ≥ 93%, cycle life ≥ 3,000 cycles (based on one power outage per week, 50% battery usage each time, for over 15 years):

　　Powering a 150W refrigerator: Battery life approximately 6.5 hours (in actual testing, the refrigerator's average power consumption during the start-stop cycle was 120W, extending battery life to 8.5 hours);

　　Emergency power supply (router + optical modem + two LED lights + charging two mobile phones): Total power approximately 40W, battery life up to 24 hours, enough for a family's basic daily electricity needs;

　　High-power short-term use: A 600W electric cooker operated continuously for 1.5 hours (boiling 2L of water) with 25% remaining battery. 2. Home Safety and Quiet Design

　　Lithium iron phosphate battery safety features: The battery utilizes a three-level protection system: cell-module-entire device. A single cell voltage of 3.2V provides six levels of protection: overcharge (upper limit 3.65V), over-discharge (lower limit 2.5V), short circuit (0.01-second power-off), overtemperature (60°C triggers heat dissipation), overcurrent (20A current limit), and leakage (≤30mA trip). Puncture and crush tests revealed no fire or explosion (in compliance with GB/T 36276-2021 safety standards), posing no safety risks for home use.

　　Quiet Operation: The fan utilizes a "temperature control + stepless speed regulation" design. When the power supply is less than 300W, the fan is deactivated (noise level ≤25dB, equivalent to background noise in a room). At full power, the fan speed is ≤2000rpm, with a noise level ≤32dB (lower than the noise level of a household refrigerator), ensuring no disturbance when used near a bedroom at night. III. Home Backup Multi-Scenario Performance

　　1. Core Scenario: Sudden Power Outage Emergency

　　Quick Response: No complicated setup is required after a power outage. Simply press the "Master Control + AC Output" button to activate power. Device access is completed within 10 seconds, prioritizing the refrigerator, router, and lighting (non-critical devices can be disabled through interface priority settings). If paired with a smart outlet, the power supply can be remotely activated via the app (requires pre-connection to home WiFi; after a power outage, the power supply's built-in hotspot is used), making it ideal for emergency situations when no one is home.

　　Extreme Power Outage Adaptation: In the event of a three-day power outage, the system can be fully charged with mains electricity on the first day (powering the refrigerator, lighting, and mobile phone). A 200W solar panel can be used for five hours (replenishing 900Wh of energy) on the second day. On the third day, the refrigerator can still operate for six hours and the lighting for 10 hours, preventing food spoilage and communication interruptions. 2. Extended Use: Home Outdoor Use

　　Balcony/Courtyard Leisure: Powers a 300W projector and a 100W speaker, creating an outdoor movie experience. Battery life is approximately 2.5 hours (extended indefinitely with solar panel charging). Powers a 600W electric grill for 1 hour, meeting the needs of a family of four barbecues without worrying about outdoor power shortages.

　　Short-Term Self-Driving Camping: Place in a car trunk (occupying space ≤ 0.02 m³) to power a 12V car refrigerator (50W) for 20 hours, or charge a phone, drone, or camping lantern simultaneously. Upon return, it can be fully charged from the mains in 1.5 hours, ensuring backup power for the next trip. 3. Special Scenario: Medical Equipment Backup

　　Compatible with low-power home medical devices (such as 80W portable ventilators and 100W blood glucose analyzers), the power supply features current stability ≤±1% and is free of high-frequency interference (measured without alarms during ventilator operation and accurate blood glucose readings). The battery supports "low-temperature protection" and automatically preheats at -5°C. Its capacity retention rate is ≥80%, making it suitable for medical emergencies during winter power outages.

　　IV. Home Scenario Maintenance and Lifespan Assurance

　　1. Daily Maintenance Tips

　　Storage and Recharging: When not in use for extended periods, it is recommended to store the device in a dry and ventilated place (temperature 0-30°C, humidity ≤60%). Recharge the battery to 50% every 6 months to prevent battery depletion. Disconnect the charging cable after recharging. The power supply has a built-in "Long-Term Storage Mode," activated by pressing and holding the main control button for 5 seconds. This automatically reduces the battery to 50% and disables non-essential functions. Cleaning and Inspection: Wipe the exterior with a dry cloth (avoid washing with water). Check the connectors (AC outlet, USB port) for looseness every three months. Apply a small amount of silicone grease to the MC4 solar connector to prevent oxidation. If you notice any loose contact, use a fine-bristled brush to remove dust (do not use metal tools).

　　2. Lifespan and After-Sales Guarantee

　　Battery Degradation: The lithium iron phosphate battery has an annual degradation rate of ≤2%. After 5 years, the capacity remains at least 90%, and after 10 years, it maintains ≥80%. This far exceeds the typical "5-year replacement" requirement for home backup power supplies. Individual cells can be replaced (with manufacturer after-sales service), reducing the cost of replacing the entire unit.

　　Safety Certification: CCC (China Compulsory Certification) and CE (European Union Safety Certification) certified, meeting household appliance safety standards. After-sales service includes a 3-year full-unit warranty and lifetime battery cell maintenance. In the event of a power outage, a 24-hour customer service hotline is available for remote troubleshooting assistance.
