Later on, my living room charger seemed to perform comparably, so I'm not sure why it was slow in the past. For home use, I still prefer the Belkin:

For travel (and used in other areas of my home), I used the Monoprice adapters:

Note, though, that the adapters are a little bulky. You might be able to find something with a slimmer profile.
 
You will, of course, need USB 3.0 cables, too. Just about any should do. I bought these, mainly because of their length:

They perform just fine, though the cables are a little thick and thus a little less maneuverable than a thinner cable would be.

After 2 people ask me if I had travel adapter to charge their iphones, I just installed this in one of the outlets by the night stand. http://www.amazon.com/Belkin-SurgePlus-6-Outlet-Mount-Protector/dp/B00ATZJ606/ref=sr_1_2?ie=UTF8&qid=1417626761&sr=8-2&keywords=belkin+usb

it has the added benefit that it screws into the wall and less likely to be taken.
