AT&T, as you may well know, is a U.S. cellphone operator. Theyprovide cell service to millions of people, and they are the exclusiveU.S. home of the iPhone. What AT&T is not, however, is a hardwarecompany. Or maybe they are, judging by their most recent announcement.The company that sells wireless service to iPhone users across Americahas just announced a new cellphone charger, one that is supposed towaste much less energy than the chargers on the market already.

The AT&T ZERO charger will become available in company storesstarting this May, and the unique thing about it is that it will stoputilizing energy (often called energy leaks or vampire power) wheneveryour phone is unplugged. It intelligently shuts itself down when it'snot being used to power a device, and while you probably won't notice agreat deal of savings on your power bill, these could really make adent in energy waste if everyone were to use one. The AT&T ZEROcharger works by automatically sensing when a mobilephone is not plugged up to the charger and cutting the power supplyfrom the wall socket, and furthermore, the charger will be sold inpackaging with 100%recycled paper.



There's no clear indication of which phones it will and won't workwith, but if it'll handle USB, it'll charge most every smartphoneintroduced in past one or two years.

:) this is perfect for me as I keep my iPhone charger pluged in at all times! I didn't know that it still drains energy... Sad

So if I understand this correctly, as long as my charger is plugged into the wall outlet even if my phone is not connected, I'm drawing energy and contributing to a higher electric bill, correct? If that's the case, I have a few chargers to unplug as soon as I get home tonight. Thanks HH for saving me money.

Good news, but seems like this is a step all charger selling companies should take...

Vampire power is not new. There are other names for it like standby power and phantom load. If you want to read more about it, here is a Wikipedia article.

http://en.wikipedia.org/wiki/Vampire_power

A cellphone charger should be the least of your worries. There are a lot of other things that will draw way more power. A prime example of this are video game consoles. The Wikipedia article has a small list of electronic devices that drain energy. I saw a study a while back and tried to estimate the cost by each electronic device. Video game consoles and I think TVs were very high, if no the top.

 

Anyways, this is something really cool that AT&T came up with. I hope this can be adopted to something like an intelligent power strip that would know that the TV and video game consoles are not in use anymore. I'm too lazy to unplug and plug things back in all the time.

 

If you think you can’t do something, you’ll never be able to do it. No matter how easy it is.

Thanks RyuGTX - interesting read. Based on the studies quoted it appears that vampire power is responsible for 5% -10% of the average household power consumption. Not a huge amount for the individual household but certainly worth addressing when one is in penny-pinching mode.

WOW, never thought some of these things drew power while its off, for one thin i never knew my tv draws power when its off xD It would be really annoying if i had to keep unplugging it every time i didn't or had to use it.

Here is a little study that Yahoo did back in 2009. The figures are annual costs of vampire power.

Alrigggght!!! Where are all the Twilight moms at ;)

I hope everyone realizes Vampires are not real! Does Santa drain your Christmas tree as well.

When I was doing computer repair and taking all manner of things apart, I have never seen a plug that allows any kind of jump in the power streams. Even if it is a minuit electrostatic jump it wouldn't be enough to warrant higher energy costs. Only cap n trade will do that! IF they are a high enough quality charger, the companies use materials that prevent any kind of arching, having them could in most cases damage the charger and possibly the devise itself.

On the other hand I have seen car chargers that are rather cheaply built that, with enough power run through them could arch and drain. Yet with most things that are made to plug into a 120v socket, they have been perfecting this protection since the industrial age. Remember that when the devise is plugged in it has to handle increased loading and that is exactly the time you do not what any spiking. When they are not connected , it has less power to deal with and is as dormant as your wall socket. My laptop had a power plug problem. It was wiggled loose, and that space between the positive and negative was shaken open, and that was when you say spiking and overheating when plugged in. To me this just seems like another way to jump on the green bandwagon and jack up a price and increase sales.

Consider this. If this vampire energy really real, don't you think there would be millions of people out there would have legitimate lawsuits against thousands of these companies pertaining to loss of money in regards to excessive electric bills?

I don't do computer repair and I am not that savvy in electronics and how they work.

But what about my desktop for example. Even when I turn it off (shutdown in Windows), isn't there still a little bit of power draw? Hence the little LED light on my motherboard which I'm pretty sure that it is indicating that it is receiving power. There is also a little light on my laptop charger that stay on even when it is unplugged from my laptop. I would assume that it isn't just powering the LED.

Maybe it does exist but no one realizes it. It would be hard for me to tell unless I had a power draw meter stuck on every one of my electrical outlets. At least according to Yahoo, the loss could buy an iPod. So about a few hundred right? But that is after 1 year. The increase wouldn't be that high on the electric bill that comes every month. Most people might think about other things like leaving the lights on or watching more TV. Also, it isn't like it increases all the time. It seems stable for the most part. So after you buy that digital cable box with DVR for example, you will only notice it on the electric bill after you bought it. After that, the price should be relatively stable. Of course, this last paragraph is just a hypothetical thought from the hypothetical statement you posed.

 

Like I said in my first sentence, I am in no way knowledgeable about this. Just my thoughts that aren't based in any science or research. Vampire power just sounds plausible to me. Though it shouldn't be too hard to test as I believe simple power meters can be had for less than $50 (I see one on Amazon for around $35). One Amazon reviewer said this: "Cell phone charger: .86 cents a year, but when charging it costs me $1.73 a year."

If you think you can’t do something, you’ll never be able to do it. No matter how easy it is.

My guess is that this will come as an optional accessory and not actually ever come with a phone.. which makes you wonder... what's the point?

It's not going to be cost effective since the amount of power drawn from a normal charger will be much less than this will cost. And it is probably less environmentally friendly to get rid of the original charger and use the second charger. Were more envirionmental resources used in the creation of these chargers than how much will be saved in their use?

Well im sure of you use this over a period of time you can get your moneys worth back considering how much this is first :)
