Unverified标称功率越大机身越重、发热越多、空载耗电越高，若日常仅用几十瓦却选1000W以上机型，会额外消耗电瓶电量并占用空间84% similarUnverified功率越高烘干越快但能耗越大，1000W机型烘干一次约1度电以内；小功率省电但耗时长实际总耗电未必低，看重电费优先选带定时和温控的机型避免过烘83% similarUnverified大容量高功率意味着升温慢和更高电费/油耗，容量并非越大越好；单人小摊选大缸只会浪费油和电83% similarUnverified容积并非越大越省电：大容积冰箱空转能耗更高，按每人60-80L计算，三口之家400-450L足够，盲目买600L以上会导致长期空载耗电浪费82% similarUnverified容量越大功率越高（6L机型常达1700-1800W），预热和烹饪能耗更高；但大容量一次做完比小容量分批做反而更省电省时82% similar
