我用開Belkin over 5年，無事無幹，條Power cord有成1.5mm.sq.，一般拖板得1.25mm.sq.，唔錯，樓主果隻牌子 ...

    查實我都知越粗越好，但有事就廢事換，如果跟來條線OK就唔想多換。
大約D 拖板寫就寫SUPPORT 到3000W左右。
根下面個表，應該要買最少1.25 mm2，如果是跟拖板的。
自己改線，買1.5MM2 最少吧，否則還改甚麼

網上查到這個, CAP 左個圖
當然下面應該是講一般長，超長當然要再粗些
It is important to choose the correct size cable when connecting to the mains. The wire has to be the correct size so that it can cope with the power demands of the device. The size stated for cables is given in mm2 and this measurement is actually the cross sectional area of the wire inside. The larger that area the higher the current it can carry.

If a cable is used which is too small for the amount of current passing through, it becomes dangerous. This results in the wire overheating and causing a serious safety risk. The table below gives typical values of cable size available plus corresponding current rating and maximum power ratings.

  入到你屋企O個條未又係單相100A,有咩分別呢?
部冷氣開一開一關surge都好勁下,如果你用好舊式抽濕機就會發現,O的電腦/電子野好快死,成日比部抽濕機開開關關surge打死
你唔信就算,因為有好多人都係一知半解,以為比雷打中地方先要買防雷拖板,但防雷拖板當中壓敏電阻對spike/surge voltage 起左好大保護作用就好多人都唔知,以為真係比雷打中左先起保護作用

brennenstuhl, Belkin, 超級星......都用過哂, 其實用係電腦都係咁用, 唔覺有任何分別
最粗用最舊果個係超級星, 接電動工具多, over 20yr, 都無問題

反而外國拖把有度唔好, 好少有獨立開關, 用起上來無咁方便
有時一插果下會出火花, 試過係 wii, mac, nb 火牛都試過
最好都係插定開拖把制最穩陣

去深水埗行個逛先得，以前買了幾個奇勝拖板，個獨立開關都易壞。
唔知呢架施落德好冇些。

連usb 個些拖板係咪通常都有些少危，線路通常都無做雙絕緣。對嗎？

其實拖板買豐葉已經好ok. 從來未壞過(我間房都多電器, 2隻8頭 一隻9頭插爆）
又平又又有獨立開關。
尋日先買咗個9頭豐葉$150
