Weird. Anytime I install switched plugs I split single plugs so one is switched one isn't. Unless it's for a specific purpose, or a customer doesn't want a lot of plugs in the room I'd never do it any other way. YMMV.
Usually on those "upside down" outlets only one of the plugs will be controlled by a switch, but the whole outlet is basically oriented that way to distinguish it from others that don't' have any plugs controlled by a switch. I certainly see the better safety aspect of that orientation as well. Seems like both reasons are fairly common (although perhaps differ by areas maybe) based on various pieces of information online, like http://homerenovations.about.com/od/electrical/f/Why-Are-My-Outlets-Installed-Upside-Down.htm
 
Only one amp, and it uses 'contacts' that slip over the outlet and contact the screws on the side?

I'd rather replace the whole outlet with one with dedicated USB charger circuitry than hope that the thing doesn't start shorting at the 'connections'. Pass...
 
Believe it or don't, the "proper" way per NECA standards is for NEMA 5-15R outlets to be installed with the grounding pin at the top or neutral prong if installed sideways. That's why an ELECTRICIAN installed it that way.

(I obtained the master electrician certification in two states so I could legally do the wiring in the new construction on my houses.)

For those questioning why: If something is dropped onto a partially-plugged in outlet, there's less chance of injury with the "new" way. (I.E. Hitting the grounding pin will make the object slide away instead of causing a short.)

(As C DM posted earlier...)
 
I bought a couple of those a few years ago. Not a great experience. First of all, it took over a year to get them, because after I ordered them they informed me that they were having issues getting them approved by government safety agencies. Then once I did get them they were unreliable (one arrived in non-working condition and had to be replaced) and they didn't put out enough power at the time to charge my iPad. Eventually they both just stopped working.

This time I bought a set of five of these:

They work great!

I put the Guidelight in my upstairs hall, master bathroom and a couple of other places where you might want to walk around at night without turning on lights. Very handy, indeed.

Good to know. Thanks!
