I received a cradle which has USB and AC power connectors, a "cigarette lighter" type charger, and an AC charger (in addition to the cradle).The item I received had an "Osmon" logo, not the "Insten" pictured. The cradle does not have a hot-sync button on it, so I need to open the hot-sync application on my Treo.Another reviewer had said that you could use this unit to charge a spare battery. The cradle I received did not have a spare battery charger. I contacted the seller and they sent me cradle that would charge a Treo 680 battery. That was nice of them, but I wouldn't count on it. If you want to be able to charge a spare battery, find a unit for your specific model that has that feature.
