yes I think they are the only ones...
what I mean is: low-tech electric devices with no electronic parts, with no direct connection to the grid while a EMP blast occurs, will work (if you have some way to generate power)...
you can see an example here

a car is hit by EMP, everything electronic stops but the electric windows and some lights still work...
