If you own a Treo 650 there are three accessories considered to be essential -- a data sync cable, a wall charger and a vehicle charger -- all of which are included in this simple and inexpensive package.While the first two are included when you purchase the phone, you will have to spend extra for the vehicle charger anyway. So for less than that will cost you in most cases, you can get another sync cable and wall charger to carry around in your laptop case.However, the biggest advantage other than the low cost of this neatly packaged solution is the portability feature of being able to use the same USB sync cable to plug into the electrical outlet and cigarette lighter attachments. One cord is always better than three when you're on the go and need to travel light.One thing that absolutely drives me crazy about the Treo 650 is the challenge of connecting the charger/synch cable to the phone. It must be noted this is a design issue with the phone itself, not the cable. As long as you're gentle and don't try to force it in, you'll be OK. (Hey palmOne ... are you listening?)Nothing fancy here, just a versatile, low-cost solution aimed at keeping your trusty Treo 650 powered and synced up whether you're in the car, in the office, or out of town in unfamiliar surroundings. Nice.
