Inside Apple’s iPhone Charger

Ken Shirriff did an amazing teardown of an Apple iPhone Charger. If you’re like me and enjoy reading in detail about how electronics are engineered, you’ll really enjoy this one. Citations and all.

The real takeaway is that it’s a very high quality product both in terms of build quality and design. That’s pretty typical of most Apple products. Ken goes on to note that it only costs a tiny bit more yet Apple charges substantially more than the competition. However the cost analysis only covers parts, not manufacturing, R&D and patent licensing which is generally substantial, especially when you have a highly customized and well engineered solution.

Standardizing Labels for Electronics

Gizmodo wants electronics to have standardized labeling to make things easier to compare. I suggested something along these lines back in 2008 about energy efficiency. Their proposal is a little more broad though I like it.

Recently I tried to get stats on power consumption for a product from a decent sized manufacturer. Interestingly their sales and support team didn’t know how much power it consumed. They didn’t even know where to get such information and suggested they could try contacting engineering but weren’t sure if it was available. Something as basic as “how much electricity does your device use?” is not available online or upon request.

So yes, I’m 100% on board with this proposal. It’s insanity that it’s so difficult to find anything more than some silly marketing specs (3D, HD, WiFi, “Fast”). It should be listed on the product details page on any online store, or on the back of the physical packaging.

It’s easy to get all sorts of stats on components when purchased individually (RoHS, Lead free, 80+ certification, power consumption, thermal specs), but buy a device full of components and it’s a mystery in many cases regarding the real specs.

Considering how much we use our gadgets, knowing such information can mean big savings. Think about your home router and switches. Just a little power savings can add up over the 3-5 years you have them installed (and running 24×7). If you live in an area where power is expensive it may make sense to actually spend more for a higher efficiency device.

EnergyGuide For Computers And Servers

Energy Star Energy GuideMost appliances sold in the US are now required to ship with the infamous EnergyGuide Label. That yellow label is most associated with major appliances, but it could be utilized beyond that. It’s a pretty simple idea in principle. The label makes it very clear how much power the device consumes, and based on average usage how much it will cost the consumer to operate on a yearly basis.

Perhaps it’s about time to adopt a similar convention for computers, servers, displays, printers, and networking equipment. Doing so would have several benefits:

  • Make consumers aware of the variety in efficiency – Different products consume different amounts of power. Being able to easily compare isn’t a bad thing.
  • Encourage manufacturers to be more competitive – While things such as processors have become more efficient (Pentium D consumption:performance ratio was worse than say the Core 2 Duo), computer manufacturers aren’t really pressed to adopt the most power efficient technologies since they may increase component costs.
  • Weed out poor power supplies and power bricks – A poorly kept secret is that power supplies and those power bricks we all have under our desk aren’t the most efficient devices out there. There are however some newer ones that have improved greatly like 80 PLUS certified power supplies. By making power consumption more visible, the really cheap power supplies become a negative in computing rather than a silent component.
  • Lower costs for businesses – It’s no secret businesses (like google) are trying to lower costs in their data centers. By making power consumption more obvious, it would be easier for them to make better choices to reduce their power costs and get the most out of their budget.

The real problem is that it’s tough to go to a manufacturer’s website or a store and tell what this device will cost you to operate, and compare to another device. That doesn’t really seem necessary. It should be easy to tell.

I think such a label should include the following:

  • Estimated Yearly Electric Use – in kWh for 24×7 power consumption pattern, additionally 8×5 for desktop computers, non-networked printers, displays. For 8×5 should also show the estimated yearly electric use in standby for the remainder of the time. That’s 1 number for servers, network equipment (which operate 24×7), maximum of 3 for everything else.
  • Estimated Yearly Operating Cost – in $ based on the above kWh data.
  • Standby Power Consumption Use – How many watts the device uses when in standby. This is really to see how close it comes to meeting the one watt initiative.
  • Standby Activation Modes – Several badges indicating how standby is initiated. Including: idle timeout, user initiated, timer, auto-wake (comes out of standby when device is needed). These let the consumer know how the device can minimize power consumption.
  • Upgradable Power Supply – Is the power supply connected to the device using an industry standard so that it could be replaced/upgraded during the device’s lifetime?

The data should be made available by easily removable signage attached to the device on shipping, made available on request in stores, and available on the manufacturers website linked from the product page.

By making power consumption more obvious, it would be easier to make a decision based on TCO (total cost of ownership) that accounted for power consumption. The bigger advantage is that it would encourage manufacturers to consider power consumption as a potential way to sell a product, and that means improving power supplies and standby consumption.

It seems like an easy way to spur some innovation and allow for better decisions by consumers. Considering the cost of power is expected to rise, and the need for IT is rising, it seems like a decent proposal. Making the most of the watts available requires knowing consumption. That way keeping servers and desktops powered on is as efficient as possible.

Google Goes Back

Google Earth Hour
To raise awareness for Earth Hour, Google took the bold step of making the page black. I can’t remember the last time they made a change this bold. They did the same thing for the Google Israel site the other day (who participated a day early to prevent conflicts with the Sabbath). According to Google:

Google users in the United States will notice today that we “turned the lights out” on the homepage as a gesture to raise awareness of a worldwide energy conservation effort called Earth Hour. As to why we don’t do this permanently – it saves no energy; modern displays use the same amount of power regardless of what they display. However, you can do something to reduce the energy consumption of your home PC by joining the Climate Savers Computing Initiative.

On Saturday, March 29, 2008, Earth Hour invites people around the world to turn off their lights for one hour – from 8:00pm to 9:00pm in their local time zone. On this day, cities around the world, including Copenhagen, Chicago, Melbourne, Dubai, and Tel Aviv, will hold events to acknowledge their commitment to energy conservation.

Given our company’s commitment to environmental awareness and energy efficiency, we strongly support the Earth Hour campaign, and have darkened our homepage today to help spread awareness of what we hope will be a highly successful global event.

Yahoo Goes Green

Yahoo is going carbon neutral. I’m curious how much is offset, and how much is reduction. Yahoo has a fairly large infrastructure. I wonder if they are using alternative power sources, or if they are going to plant a million trees. They do mention:

These projects could include a wind farm in India or a small-scale run of the river hydroelectric project in Brazil. We’re also looking to invest in emerging clean technologies.

Interesting. I wonder if we will see things like carbon neutral VoIP, carbon neutral bandwidth, carbon neutral data centers / colocation / hosting?

Lights Out Pt. 2

CNN has a nice little article titled Iraqis’ top 10 tips for enduring blackout in the heat. Definitely worth a read. Funny, yet informative. Suddenly, for about a day, NYC and Iraq could really relate.

Took the day off. Got Korean/Japanese food (good stuff). So it was a surprise 3 day weekend. Hurray! 😀

Interesting that outage may be due to one line.

Some other linkage:

Lights out

Working yesterday… and the power went out. Throughout the IT floor, all I could hear was cursing, and the sound of people slamming their keyboards. Lots of work was lost. Moments later, forced to run down the stairs (evacuate the building) and out the building into the chaos on the streets. Seeing a few people get tapped by speeding cars (didn’t appear to be hurt)… Decided not to step into the streets. Went into the main building, and back upstairs (STAIRS). Got fed by the cafe with “emergency rations (namely Häagen-Dazs iced cream), and hung out. Even found emergency power in the mail room (with plans to use it to watch TV). Then got a car home late last night.

I hope they hang whoever messed up causing us to lose power.

“Time Square without the lights… is just another street.”
