Technically the Zmax is a Mod since it has built-in protection and electronics whereas a Mechanical is just that; strictly mechanical with no wires or electronics. The KTS and the Chi-you are both mechanicals. Both types of devices have their place but mechanicals are necessary when going sub-ohm. They also have less chance of failure since they have no electronics however that also means they provide no protection and are always outputting the maximum power possible from the battery. That's why it's imperative to not only buy quality batteries but also ones that are appropriate for use in a Mechanical (IMR's or protected).
All that said however, you could use the Igo-L on any of the devices; you just wouldn't be able to use it with a sub-ohm coil on the Zmax because it's built-in protection wouldn't allow it.
