I've been at war with "wall warts" for decades. Within a radius of 5 feet from where I am now sitting, there are at least 2-dozen in various states of usage. To my right, near my desk as a pile of chargers for various devices I use on a regular basis; cameras, headsets, radios, etc. They are all unique in some way, for no good reason. (other than perhaps to create a demand for additional accessories)
For years, I've been arguing that we need some sort of low voltage standard for these devices, just like we do for 120-vac appliances. Instead of dozens of wall-warts throughout the house, I'd much rather have a single, high quality regulated DC power supply that could run all of these things efficiently. Ideally, future homes would be constructed with low-voltage outlets in each room just as they do with high voltage ones.
This device appears to kind of address the issue, but it's just waaaay too complex, especially for non-geeks. Get rid of the silly solar cell and superfluous programming gimmicks and hardware and I'd consider buying it.
