You will have a hard time using 'less power'. The whole point of a soldering iron is it turns electricity to heat. Your current model uses 24 watts (12v at 2A) Anything with remotely similar capabilities will be in the 10-30 watt region.

Plus, if you run it on AA's, you can only get about an hours time on full....
