Westinghouse Commits to Green Plug's Universal A.C. Adapter

Ian Lamont writes "Westinghouse is the first major electronics manufacturer that has publicly committed to using a 'smart power technology' that will let people use a single universal adapter to power their laptops, cell phones and other electronics. The universal adapters, which use a technology developed by a startup called Green Plug, will act like a hub that several devices can plug into, and will also shut off the power supply when the device is turned off or has finished charging. The first are expected to go on sale in early 2009 for under $100, according to Westinghouse's CTO. Eventually, Westinghouse and other manufacturers that use the technology could stop shipping adapters with their products, because customers may already have universal adapters at home. However, some manufacturers may not be inclined to use universal power adapters: the article notes Apple gets supplementary revenue from the sale of proprietary connectors for the iPod and other devices."

It's not like that

First: yes, you will have just as many power supplies as items to be powered and/or recharged. Nothing new there. (Oh, that's not counting their power supply hub. But we'll ignore that for the moment.) Yes, these supplies will cost more initially than the present ones. But like any investment, it's supposed to save you money in the long run.

On the other hand, when your cell phone dies, or your electric razor, or your battery charger, you can buy a new one without buying a new power supply -- because the power supply is universal, see? Less waste in the landfill, less use of resources (one less supply to build), less money to buy the new item.

And if you dash off on a trip and forget your cell phone charger, but remember your electric razor charger -- hey, no problem! They'll just have to take turns. Or you can charge them both at night because you're not using your laptop.

In fact, any decent hotel will have a charger installed right in the wall. Just in case.

Or you're staying at a friend's house; you can borrow his.

As for the supply being bulky, they've already got a supply that can adjust to any voltage in its range.

Since the supply actually talks to the device, it will know when the device is charged, and turn itself off. Unlike the current average wall wart, it will stop using power (or only use a miniscule trickle) if the device doesn't need power.

So: Initial expense will be higher, but you'll be able to save on later purchases (because you can re-use the old supply), you'll save on power (because of lower vampiric power draw), and all the power supplies will be interchangeable.
