Think someone said some time ago it was basically a Ctek branded differently but whatever it is it works perfectly with 6V and 12V batteries.
I believe there was a myth floating around the internet that the Lidl one was a CTEK, but it was disproven.
Either way, CTEK aren't the be all and end all of chargers so no real worry. The Lidl one has been proven over and over by many a forum like this and seems to come very highly recommended and is less than half the price of alternatives, so if they are available, buy one - or 2 if you want a spare
if I was in the market for one, this is what I'd do.
Personally, as an alternative, for future reference / if the Lidl ones are out of stock, I can recommend the Oxford Oximiser 900.
I've had 2 for 4 or 5 years now, used daily on a variety of batteries in my Elise, 944 S2, Alfa diesel...
You used to get them for around £20, but a quick google search shows me that they seem to be £30 now (and have changed colour).
Only problem I've had is that the one wired to the car corroded on the Elise (the battery is in the front compartment, near an open grill and the rad, so pretty open to the elements / heat cycles / all the stuff you don't want to avoid corrosion!)
A replacement was a couple of quid from eBay though and I suspect most will be the same.
If you've got bags of cash to throw at one, you can buy an official Maserati one on eBay:

I have one of these (it came with my car) and can confirm it works, and is basically a low model / low feature CTEK with a bit price tag and a European plug
If you want to spend twice as much on the same thing you can get a similar one in red with a horse on it:

There are usually similarly prices black ones with a bull too, but they must be out of stock
You get other branded CTEKs for more than a normal CTEK too, Mercedes, Maybach, Aston Martin, Alfa 8c, Bentley, Porsche for equally silly inflated prices.
They are all the 6 stage XS 0.8 (which seems to be the US800 if you are over the pond..) so you can also buy the same thing for Maserati/3 or Ferrari/6
