A Pi zero does not use 5v, 2A. It uses 5v and ~100mA plus whatever you have connected to it needs. Recommended PSU is 5v, 1.2A.
A zero2W uses 5v, ~350mA with a recommendation for a 2A supply.

Without knowing more about the tutorial you're using it's impossible to say for certain whether that module will work or not.
If you're powering the Pi directly from that unit odds are against you and I'd expect lots of low voltage warnings and corruption of your storage media due to brown outs and/or total power loss.
If you're using that to charge a battery (e.g. a single lithium based cell) which then has its output boosted to 5v it'll probably work.
