If you are the sort of person who is always short a charging block and cable, the PocketPlug may be just what you are looking for.
The PocketPlug is a case with two flip-out prongs that plug into an electrical outlet. You can charge your iPhone, no cable or transformer needed.
The case, which is plastic coated with so-called soft-touch material, provides some protection against dings and dents.
The case also has a micro USB port on the side that allows charging but not syncing. To sync the phone by wire you must remove it from the case. It has a cut-out for the control buttons and a chamber on the bottom that redirects sound so it comes out of the front of the case.
One difficulty: You can use only headphones with a straight, thin plug. Other kinds of plugs won't be able to reach the deeply recessed jack.
The case is available for the iPhone 5 and 5s, 4 and 4S. The company said that a case for the Samsung Galaxy III is on the way.
While certainly a convenience, the PocketPlug is a bit expensive at $70. But I suppose you have to ask what it's worth to never again have to say, "Oh no, I forgot my charger."
