There are a number of ways to carry "power' with you such as external power packs but none would be as reliable or as efficient as the batteries designed for the camera.the other consideration is obviously weight as you would have to carry any dead batteries out with you,its not good practice to throw dead AAs away as you go.the power to weight of the camera batteries is considerably better than any batteries you might use in an external pack and IMHO you should carry an extra camera battery or two,I know these are not cheap but will give you peace of mind .Have a great Trip gary ng

I know that several people tried the DIY approach. As far as I
know, the AC power adaptor has a standard 'audio plug' like
interface. You can just get the appropriate RC battery and match
with the necessary wire plug(all in Radio shack). The hard part
would be about the voltage. But I am sure different people have
done it successfully with the S110(?) and S30 too. There is a
number of threads about this DIY battery pack issue on this forum.
Your best bet seems to be making use of the AC power adaptor and
plug those RC type battery to it.
I am thinking along the same line but could not find anything in
the market that I can adapt to an external battery pack of AA's.
