From the user summaries, the cable above doesn't have a data connection.
A summary of this thread would be nice. I think it's important to have a few OEM wall-chargers and OEM DC chargers with purchase links, parts numbers and specifications listed in case you need to buy one than scavenge one up from around the house.
It's not that helpful to say "The charger from my #### phone works." While that may be true, there seems to be quite a variety of chargers shipped with each phone. Both my chargers say they are for a RAZR2, but the AC is rated for 550 mA while the DC one is rated for 950 mA. Having the highest current capability is always a good thing.
