For sure the cheaper ones are just transformer coupled (the wire that it clamped over being 1 turn) so they would be AC only. The more expensive ones ($100-200) do have a "Hall effect" type of device and
can measure DC. I have not seen one with better than 0.1 amp resolution...just not good enough.
