Unverified82% confidenceDecision RuleTime unknown

看瞬时电流而非峰值电流：厂商标注的峰值电流常是理论值，实际有效的是持续瞬时电流（一般为峰值的1/2到1/3），选购时以瞬时电流≥300A为汽油车安全线

Unverified标称额定功率外还需关注峰值/浪涌功率，电机类电器(冰箱压缩机、水泵、电动工具)启动瞬间电流是运行时的3-7倍，额定功率够但峰值不足仍会触发过载保护80% similar Unverified启动电源的峰值电流（Peak）是瞬时值仅持续数秒，选购应关注持续电流（Cranking Amps）参数，虚标产品常只标峰值而隐瞒持续电流79% similar Unverified购买前需确认自身实际用电设备的峰值功率之和，EcoFlow等户外电源的额定功率是持续输出上限，启动瞬间峰值功率可能是额定值的2-3倍，选购时应留有余量。79% similar
