What’s the difference between Maxi II and Mini II incubators?

The only difference between the two machines is the size and egg capacity. The Maxi II is the larger machine and holds up to 14 hen sized eggs or equivalent whereas the Mini II holds up to 7 hen sized eggs or equivalent.

The Eco, Advance and EX versions of the Maxi II match the specifications of the Eco, Advance and EX versions of the Mini II. The only difference is the egg capacity.
