　　III. Typical application scenario adaptation instructions

　　Construction site (multi-tool operation): Recommended Anker SOLIX F2000 and Stager PT2000. Their core advantages are large capacity and long battery life, multiple interfaces for simultaneous power supply, pull rod and wheel design for easy movement on construction sites, and a 3000-cycle lifespan to meet high-frequency usage needs.

　　Outdoor repair (scenarios without AC power): Recommended MEITESI G2000 and Tanbos Smart 2000W, supports solar charging, lightweight design (≤25kg) for easy vehicle transport, wide operating temperature range to handle extreme outdoor environments. Emergency repair (rapid response): Recommended Makita BAC01+PDC1500 and Anker SOLIX F2000, fast charging (1.4-2 hours to full charge), UPS/EPS emergency switching function (≤15ms) to ensure uninterrupted tool operation. For tool brand ecosystem users: Prioritize Makita BAC01+PDC1500 (compatible with Makita LXT batteries) and DeWalt DCB1800B (compatible with DeWalt 20V tool batteries), battery compatibility reduces additional investment, and brand after-sales service is more comprehensive. IV. Selection Decision Guide Priority Selection Criteria: Clearly labeled "2000W continuous output + ≥4000W peak power" (avoid falsely advertised starting power) Battery type: Lithium iron phosphate, cycle life ≥2000 (For high-frequency tool use) Features a pull handle and wheels or an industrial-grade portable design (for construction site/outdoor mobility) Supports overload/overtemperature/short circuit protection (essential for high-load power tool scenarios) Power matching formula: Single tool use: Power station continuous power ≥ tool rated power × 1.5 (allowing for starting margin) Multiple tools used simultaneously: Power station continuous power ≥ total rated power of all tools × 2.0 (to handle surge current from simultaneous startup) Example: Using a 1500W chainsaw + 500W angle grinder simultaneously, should a continuous power supply of ≥ (1500 + 500) × 2.0 = 4000W be selected? No, correction: The total power of multiple tools is 2000W, multiplied by 2.0, it needs to be 4000W, but a 2000W continuous power station is recommended. Therefore, in practice, avoid starting excessively high-power tools simultaneously, or choose a higher-power model. Users are reminded to match tools appropriately based on their power requirements. Avoid pitfalls: Refuse Products labeled "corrected sine wave" or without waveform markings (easily burn out tool motor coils). Beware of "falsely advertised peak power": Request a third-party power testing report, focusing on verifying the start-up power duration (≥4 seconds is valid). Prioritize tool brands (Makita, DeWalt) or industrial-grade energy storage brands (Anker, Stacker), as consumer-grade products may not withstand the high load impacts of tools. For outdoor use, IP protection is essential: at least IP44 (dust and splash resistant), IP54+ is preferred for construction site applications.
