測試總結:
◆3個NEMA 5-15R美式三孔交流插座L/N插孔具備彈簧護蓋
◆可透過米家APP使用遠端控制、定時控制、電量統計,所有插座與USB一起受控制及統計
◆未具備零電壓點切換能力(零電壓點切換可避免繼電器接點產生火花,降低負載通電瞬
間突波)
◆APP的顯示功耗更新速度從10秒到25秒不等
◆具備1個USB-C及2個USB-A輸出,支援主流快充協議
◆含本體控制電路耗電下空載功耗1.33W,最低效率59.4%(USB-C的5V/0.5A),最高效率
83.8%(USB-A的12V/2A)
◆USB-A輸出具備電壓補償功能
◆9V/12V輸出下,電流超過額定時輸出電壓會產生壓降,產生壓降同時會發出滋滋聲
◆USB-A於9V/12V輸出下,電流要超過3.5A才會截止
