To be perfectly honest, I think of this in two categories of answers:
1. For the older stuff, prior to the contemporary time period, it's mostly magical light sources despite the visual stylings.
2. For the newer stuff, contemporary and onward, they have some fancy magic-augmented electronics.
In all seriousness, basically everything in this world, no matter how technological, would have some underpinnings of magic since magic has always been around and is such a core part of this world and its culture.
Sure, but would all magic necessarily work the same way over centuries and centuries of time and across large physical distances, or would they discover/invent new and improved ways of doing things with magic just like we do with our technology, not all of which would be directly compatible? Saying they all just work because it's all magic is the "a wizard did it" solution, which is of course fine, and it's just a game (and a very, very minor aspect of it) so it doesn't really matter too much in the grand scheme of things, but that's something that's bugged me about a lot of magical fantasy.
Someone comes up with this great alternate universe with its own rules for how reality itself works, and the really good ones explore how that affects the development of cultures and societies and even more mundane things like people's everyday lives, but while they often go into the political and historical implications of whatever magical system their world operates on, they frequently ignore the technological side of things or get it hilariously wrong. There are occasional exceptions, but they're unusual.
I guess you can blame my uncle giving me several boxes of classic hard sci-fi books when I was a kid, from Asimov to Clarke to Niven, so even though I still like fantasy, I'll always have Science! nagging me from the back of my head sometimes. Heh.
