RE: why is Dell selling many different watt chargersr ?

It will depend on:

The CPU (quad cores need more power than dual),

The GPU (hybrid setups need more power than integrated Intel)

The docking station chosen.

It's always safe to use a higher-wattage adapter than what was shipped, but never safe to do the reverse.

If you have an i7 version with nVidia or AMD hybrid GPU, the 130W should be the correct adapter.
