Water change pump

[StevenA]

MA sell an Aqua Marin water change pump(£29-99) that looks exactly like the type of thing that I think people use in caravans etc. for pumping water. I think the MA one comes with a transformer, but I was wondering if it's possible to buy a cheaper one from amazon (https://www.amazon.co.uk/gp/product/B07CZYJRFR/ref=ox_sc_act_title_1?smid=A2FQZT4CAV9EY6&psc=1) and put a plug on it or do something so it does the same job indoors that the Aqua Marin one does, but for considerably less money?
I want a pump that fits in a 25 litre container to pump water into an aquarium.

It states that you need 12v 1.5amp power supply if im correct. So easy way is to buy something like this for the plug
