Sturmey-Archer hub magnetos are of course the 'Dynohub (tm)'. The classic GH6 was produced from 1946 through 1984. They were rated at 6V and until the early 1970s 2W, afterward 1.8W. Modern Dynohubs like the HDS12 are 6V, 2.4 or 3W.

Fun fact: Some modern Shimano hub dynamos, like the S701, are rated at 6V, 1.5W.
