Universal Power Adapter
Posted by keelynet on February 8, 2009
Imagine a one time purchase of a device that will provide power for all your rechargeable devices no matter the voltage and current requirements.
What a huge threat this would be to all the companies who make replacement power supplies at jacked up prices!
“Last year, there was a lot of hopeful discussion surrounding an initiative to have the consumer electronics industry standardize their products on a USB-based universal power adapter devised by Green Plug.
Eight months later, the effort has stalled. The reason: manufacturers have balked from using Green Plug’s technology. ‘… Gadget makers seem to have no compelling financial incentive to adopt Green Plug’s technology.
It would require them to add Green Plug’s chip, or similar hardware and software, into every phone, camera, or music player they build, making them more expensive and more complicated to build.
Another stumbling block for manufacturers: A universal power supply would kill the market for replacement power supplies. Manufacturers sell these at a steep markup price to customers who lose or break the original one that came with the device, and aren’t tech-savvy enough to procure a low-cost generic replacement.’
Green Plug is now trying to drum up public outcry through a (slow) website, but the number of supportive comments and votes remains relatively low.”
/ Billions of devices including laptops, printers, speakers, routers, modems, cell phones, entertainment devices, power tools, cameras and so many other portable electronic devices require a power source that converts between 90V and 254V wall power to device-specific DC power.
That means that these devices require unique power converters, and that is very costly, is extremely inconvenient and contributes to wasted resources and pollution.
With Green Plug, however, intelligent power supplies communicate with electronic devices and agree upon device power requirements for all devices connected to them.
All cables and connectors are uniform; so, they work with any device! Being intelligent power sources, they eliminate wasted “phantom power” (power that is wasted when chargers are plugged in and either connected to devices that are fully charged or have no devices connected to them) and improve power utilization and efficiency.” – Source
