The Mobi Products PowerCradle for Treo 700p, Treo 700wx, Treo 700w, Treo 680, or Treo 650 allows you easily to synchronize and charge your Treo with any USB-enabled computer. With this cradle on your desk, there is no need to fumble around with finding and plugging in the right cable. Just dock the Treo into the cradle and you are set. You even get an extra stylus with the cradle (the cradle has a stylus holder), so you don't need to use the Treo one.
The cradle can be powered either by your computer's USB port or with the bundled AC Charge, perfect if you want to use the cradle away from a computer (say on a nightstand).
There is no hotsync button on the cradle, so Palm OS users need to use the HotSync application to initiate a sync. Windows Treo's sync automatically when docked.
