Hi there,

I came across this thread looking for a surge protection power strip for electrical devices which I plug on ad-hoc basis.

Reading your replies, I think a TRM-NIF-3-BU model would best suit my needs (laptop, table-top fan, a further power strip connected to this TRM-NIF-3-BU for a USB charger + radio + desk lamp).

However, this review says that I need a base unit "TRM-NIF-IT BU+PE" first:

Would like to know, is the base unit necessary or can I just plug TRM-NIF-3-BU to the wall socket directly as the base unit for my needs?

Thanks.
