External Power for S100

I read many posts on powering canon powershot cams.  I'm not very good at electronics.  Can someone tell me if I'm on the right track here with powering my Canon S100 with one of those 12v/5v battery packs?

Do I then use one of these as the next step?

And finally, to this and then my S100?  Also, I'm assuming I'll just cut of that right angle and some cable and wire that to one of those regulators?  How do I go from the 12v or 5v to the other end of the regulator?

As of right now I can get about 2hr and 10mins from the Canon factory NB-L5 battery for my CHDK motion detect bird picks.  I'm thinking that if the above is correct I might get maybe 4 or 5 hrs from one of those 12v/5v battery packs.  Does that sound about right?

 2.35 0.7 DC Tip Plug Connector Lead with Cord Cable For AC Adapter 2.35mm 0.7mm

Is this what I would need from the regulator to the ack-dc30 fake battery?

The regulator in the first picture looks good. Not sure of the spec. of the second one. Where did you find it?

I found it here.

http://www.amazon.com/Variable-Voltage-Regulator-Output-PTN78060WAH/dp/B00AHDJ6EG/ref=wl_it_dp_o_pC_nS_nC?ie=UTF8&colid=25FWVOAWTKPPN&coliid=I2G0YJ91F15IT6

Am I on the right track with my build?

Generally yes, as ahull wrote. Personally, I'd be a bit careful to buy the cable with the connector for the "battery replacement"/adapter (as shown in your reply #4) separately from this adapter. Canon uses so many combinations of diameters of the inner and outer contacts that you can never be sure to get the right match. The connector details can get even more messy if you buy not the original Canon battery adapter. It's best to buy the adapter and the connector for the adapter together.

And a ahull said, the first 12V -> 3.7V converter looks good. The cameras draw shortly 2A or more, hence it's hard to say if the other converter from your first post may be usable.

FYI - here is a sequence of pictures (from this post) showing the regulator I used. The buck regulator you choose is not too important, so long as it will handle 2A or more, and you get the polarity right. Feed the 12V in to the input, and check that you have the correct voltage coming out of the other, and you should be fine.
