Hi all,

I need to replace a laptop style (12V 7A) PSU (not for a laptop) and
was wondering if the sort of thing you can get to power 12V LED lights
would be suitable?

I'm talking of this sort of thing:

Is it just a 12V SMPSU or is it summat 'different'?

I find it weird that they don't mention the output voltage in the
blurb, just a range of wattages (it does say 11.4V on the item itself
though).

Transformer implies non-DC. I see others in the range on a different
website actually say AC.

I would pass and purchase a true 12V DC supply, if that is what you want.

Something like this at £8.77 for 12V @ 10A:

And cheaper than the Toolsatan offering. Only concern is the output
earthing arrangement. I might be wary to treat the output to be SELV
without knowing more about the unit.

Of course there are others.
