This can be pretty much summarized as:
Using a fuse that's worse than your impulse charge --> The teleporter will break.
Using the Homebrew Impulse Charge --> You'll only travel a few meters.
If none of the former happens:
1. Regular Impulse Charge + Basic Targeting device --> Zombie-filled planet ending (insufficient power, wrong angle)
2. Regular Impulse Charge + Extra Precision Targeting device --> Cruise ending (insufficient power)
3. High Power Impulse Charge + Basic Targeting device --> Otto ending (wrong angle)
4. High Power Impulse Charge + Extra Precision Targeting device --> Best ending
It is interesting to note that all four conclusive endings end (sorry for the repetition) with a picture of the planet you're on (the spaceship, in ending 2).
