Hello. I purchased a POE switch to power 4 cameras, of which I'll arrange to be installed. The problem is, it came with no power cable, for which I was aware of. I know. I was hoping to source a cheaper power lead and keep costs down.

However, upon seeing another listing (where I sourced the image) of the same device I have, with a really fat adapter housing, I suddenly wished I had gone for the switch and the plug. Check out that adapter. Inside, it'll probably have all the gubbins to convert the volts and amps or some regulator or whatnot. (shrugs) I'm no expert. Searching for the name of it (N14939 LEI) yields no cheaper option, nor are they any for the UK plug socket.

Asking the seller which alternative power lead goes with what, I feel I'll get a dishonest answer. So, that's why I'm here for advice. To ask if I can use an alternative power lead for this POE switch? I am still well within the return window. The last thing I want to do is to return it, but if left with no other option, I might have to.
Below are the specs for the deivce from the listing.

TL-SF1008P 8-Port 10/100Mbps Desktop PoE Switch with 4-Port
