Summary: Looks like it is something I would like, but I had problems charging the unit for the first time. Either the connector on the unit was not properly soldered, or the cord is bad on the car charger.
Excerpt: Original (Staples bought unit) failed under warranty. FIRST Refurbed unit had duplicate search results for same location. SECOND Refurbed unit does not power up. Serial number is same as original. Suspect original DEFECTIVE unit sent back to customer. Deceitful business. Poor service.
