Devices these days like cellphones and laptops automatically come with a power adapter to convert AC power to device-specific DC power, and they’re always different from one another. This causes a lot of waste when people decide to get rid of their devices and the adapters end-up in a land-fill. To help reduce the amount of energy used and material waste from battery-powered equipment, a company called Green Plug has introduced a Universal Power Supply that they’re hoping will become wide-spread amongst technology companies.

Green Plug’s technology allows each device using the universal power supply to communicate the power that it needs to the power adapter. This means that multiple devices are able to use just the one adapter. On their website, they talk about their project and say:

We are dedicated to the global proliferation of efficient power charging systems that utilize standardized power supplies, cables and connectors. A typical home or office has a dozen or more power transformers that convert between 90V and 254V wall power to device-specific DC power. Every adapter is physically unique and therefore is thrown away every time a device is replaced.

Not only is this more “earth” friendly, but it would also be more convenient for people not having to worry about the various adapters for their devices. The first company to start using the Green Plug technology is Westinghouse who want their customers to be able to use a single adaptor for their laptops, cellphones, and any other electronics device that they have. They’ll also save money by using a universal power supply.

InfoWorld recently wrote about the growing support for a universal power adapter and explain that each adapter would act like a hub that several devices could plug into. They say, “the first (adapters) are expected to go on sale in the first quarter next year for under $100. The adapters also will shut off the power supply when a device has finished charging or is turned off, giving further energy savings.”

We don’t know about you, but we’d love to see something like this take-off!
