I guess most people know the issue of losing a power adaptor for one of their devices. In my case I just lost this kind of adapter. I don't see how these adapters should be that expensive to manufacture and I guess there should be some overlap in terms of electrical specifications for different adapters. Is there any way to find a suitable low-cost alternative to Amazon or similar site for a somewhat uncommon adapter such as the one I've just lost?
note: transformer is for 220V (Europe), so answers need to reflect that
