Picture of details on USB AC Adapter, including 4.2A capacity
EDIT 1/21/14: The price has dropped $1 to $6.99 as of January 21; TRU appears to have increased to a 30% discount on clearance items. Item is still in stock for shipping and for store pickup at some B&M locations.

Toys R Us has the XtremeMac Universal Charging Kit for $9.98 - 20% off sale for clearance items = $7.98 at checkout. This kit includes a dual USB wall charger (with US wall plug adapter) as well as a single USB car charger. It's in stock for shipping to home, as well as likely in stock in various stores for in-store pickup.
Some Toys R Us stores near me in the DC area had it in stock and available for free pickup, but others didn't. For shipping, it is unfortunately not eligible for Shoprunner for those of us who have the service. TRU usually accepts Shoprunner, but I think because this is a clearance item, they want $6-8 or so to ship this item (unless you have other items to satisfy the free shipping minimum). I just ordered it for pickup at a local store, and they held one for me rather quickly!
Amazon link for this item; it's $21.99 sold/shipped directly from Amazon at this time. So this is a good deal over what you'd pay elsewhere, and probably even cheaper in price than similar no-name power adapters.
The AC adapter (model USB-AWC-11) seems to be the best part of this deal: it has 2 plugs, each of which is rated at 2.1 amps. As seen in the attached picture (actual item), the AC adapter as a whole is rated for 4.2 amps, or twice the 2.1A rated load for each port. In other words, that's 20 watts, which is pretty good for a USB power adapter. You aren't going to find a decent quality power adapter that outputs this much power elsewhere for $8.
This is very good if you have power-hungry devices like tablets, some cell phones, and other USB-powered devices that need more power over the typical limit of 1000mA or so from most USB power sources. (& if you have a Raspberry Pi board, 2 amps is really good, but not 100% necessary.) I haven't pushed this adapter to its limits, but will probably use it with power-hungry devices like my RPi and HP Touchpad, the latter of which insists on being connected to the high-amperage AC adapter when empty. If I do some stress testing and have any updates, I'll post them here.
You also get a car charger with 1 USB port on it. I'm not sure what amperage it's rated for, but is pretty small (extrudes about 0.5cm from the socket) and has 1 USB plug on it. It should probably be good enough to charge your phone or possibly tablet in the car, though. No cables are included, but these are standard 5-volt USB ports that should work with most any USB charging cable.
Especially for a brand-name product (hopefully higher quality than "no-name" chargers of similar price), this pair of chargers seems like a nice deal for the price. Even more so if you have a tablet or other power-hungry device that needs a charger that can offer more power than regular USB chargers.
