Solio charger is what you may be looking for. If your AA and 123 charges are 12V car lighter compatible you maybe be able to get a cable that replicates car lighter port.

I know that Solio Classic had that cable available for extra $20 bucks so the package with charger was about $120.

That system works. Also there are unlimited number of tips for other electronic devices that you can use with this combo. And since charger has internal battery you can store the power for later use.
