　　IV. Selection Decision Guide

　　Priority Selection Criteria:

　　Must be labeled "pure sine wave" + THD value (lower is better)

　　Supports UPS/EPS emergency switching function (essential for sensitive equipment)

　　Battery cycle life ≥ 2000 cycles (reduces long-term operating costs)

　　Power Matching Formula:

　　Single device: Power station continuous power ≥ device rated power × 1.2

　　Multiple devices: Power station continuous power ≥ total power of all devices × 1.5 (reserves startup margin)

　　Pitfall Avoidance Tips:

　　Reject "corrected sine wave" products (THD > 15%, prone to equipment burnout)

　　Beware of falsely labeled parameters: Request a third-party THD test report

　　Prioritize brands with international certifications (UL/CE/FCC)
