As WormDoes said, any USB charger will work, but you'll have better results with one that has a 1 amp output. I had some left over from my iPhone 3GS like the one you linked to. They worked, but were 0.5 amp output and charged slowly. The TBolt is powerful enough that a 1 amp charger is usually recommended, works better and charges faster. The same is true of car chargers. If you are doing any navigation in your car and trying to keep the TBolt charged, an 0.5 amp charger may have trouble keeping up and will charge slower.
I also use OEM wall chargers from Verizon. They're more expensive, but seem to be made better and last longer than most of the cheap chargers you get online. That's strictly my opinion and I may be wrong, but I personally have had better luck with the OEM chargers. Also, I know you asked about USB chargers, but for a wall charger I prefer the ones that are directly wired with a 6' cable as opposed to the ones that use a USB cable. No real good reason for it other than I like the longer cable and most USB wall chargers come with a 3' to 4' cable. I already have more micro USB cables than I know what to do with and 6' USB cables are more expensive and just an extra expense.
Again, just my opinion and others will probably disagree.
I just saw the one brizey linked to and it looks like the one that came with my TBolt. It's both a good 1 amp output charger and a good deal.
