AT&T says its upcoming Zero Charger doesn't use electricity while your smartphone is unplugged. But is it really worth it?
But is it really worth it?
Joseph Kaminski at SmartPlanet sister site CNET put three popular phone chargers to the test to see if mobile phone manufacturers are offering you real savings -- or just trying to slip you another pricey accessory.
The suspects: Chargers for the Apple iPhone, Motorola Droid and Palm Pre.
The test: Each charger was tested over 16 hours in CNET labs.
The verdict: Modern cell phone chargers draw minute amounts of power when plugged in.
They all drew an extremely low amount of power and cost the user very little per year, ranging from 6 to 22 cents based on our calculations. If we assume $29 (the cost of your average charger, assuming AT&T's would cost the same) and divide it by 12 cents (the average of all four chargers' annual costs), it would take 241 years for it to pay for itself.
In other words: if you're interested in saving significant amounts of money on your electrical bill, you're better off shutting off a light when you leave the room than buying a new "zero draw" charger.
In the meantime, here's hoping that zero-draw chargers become the global standard. After all, even little amounts of power can add up worldwide.

But thats not what its all about. It never is... Ok so the individual may save miniscule amounts compared to his overall usage, but add all those individual amounts up and its a significant chunk of the total power used by all the individuals. 241 years worth of coal burned solely to power unused equipment for millions of individuals is a huge pile. To ignore that isnt smart at all. Secondly, its a 'foot in the door' device. Hopefully it will become popular enough to influence the faddy markets and then all our consumer devices will be powered from them. This being the case, there will be more significant savings for the consumers both directly, and because power is cheaper overall as a result of less wastage. My Grandmother knew this. 'Count the pennies; the pounds will look after themselves.' she said... Peace
If it is not coat affective it is not green, it is a luxury. Making and selling new chargers when the old one works is not green. Using what you already have is green, usually even if it is a clunker.
That is absolutely not a valid point! Just because it may take 241 years to pay for this particular device/appliance, does not mean that it should be scoffed. Vampires are an overwhelming drain on our nation's power grid after you tally up the entire draw from every household, office, etc. No matter how small the savings is on a single device, the collective in your home is important and every vampire needs a proverbial stake in the heart to fix a very large issue.
More of big brother trying to rescue us. The techology may exist for a zero-draw charger but somehow, I bet the cost will be more than the 25 cents over the two years that a typical cell phone will last. We can save electricity by putting 50 cents of extra resources in the charger. THANKS BIG BROTHER. Get a life and Get OUT of mine.
