2.1, 2.4, Lightning, 4, Air, Mini…what does it all mean?















It means that a square is a rectangle, but a rectangle is not necessarily a square.

First, let me point out we are talking about charging speeds, and in particular, charging Apple products. The question comes up often when reviewing charging systems for a fleet of iPads, “What is the best charging speed for my solution?”

Here are the charging speeds of the various iPad generations at the two amperage rates that today’s iPad charging carts and wall stations support:

iPad Model (connection type) 2.1A 2.4A
iPad 4 (Lightning) 7.0 hrs 5.0 hrs
iPad Air (Lightning) 6.0 hrs 4.0 hrs
iPad Mini (Lightning) 5.5 hrs 3.25 hrs.

If you want to take full advantage of the 2.4A charging speeds of iPad 4, iPad Air or iPad Mini, then go with a charging cart or wall mount that is MFi (Made for iPad) and able to charge at that full rate.

DM10-1001-rem-ipad_smIf the nominal difference in charge times is not as pressing as budget limitations, or if you are using a mixture of older and newer Apple devices, then consider a charging cart or wall station that charges at the 2.1A rate.  The charging time difference could be a moot point based on your usage model and charging patterns.  For instance, are the iPads going to charge overnight anyway?

Ergotron offers both 2.4A and 2.1A iPad charging systems:

  • Ergotron’s MFi (Made for iPad) 2.4A charging carts and wall stations come pre-cabled for Lightning devices, but are also backwards compatible to swap in 30-pin cables for charging older-generation iPads. Lightning-cabled devices will charge at the full 2.4A rate, while iPads connected via a 30-pin cable will still charge at their 2.1A rate.
  • Ergotron also has 2.1A versions of its charging carts and wall stations as well. Whether using 30-pin or Lightning cables, and whether using iPad 2, iPad Air or iPad Mini, all Apple devices connected will charge at the 2.1A rate. This is an economical way to go for mix-and-match iPad generations, and if the devices will be charging all night any way.

One final note, it is also very important to make sure that the charging cart or wall station that you choose is fully safety-certified.  If not, your devices, students and staff are at risk. For more information about this, we’ve put together a brief white paper for you to share with your IT group or other stakeholders in the decision process.

Choosing the right device charging station…a few considerations


More than 90 percent of Americans own a cellphone, 32 percent own an e-reader and 42 percent own a tablet computer. Schools are facing a burgeoning amount of tablet usage in their classrooms, whether that be BYOD, 1:1 or 1: to many. And it is falling on IT/Media to figure out how to best charge, sync, store and secure this investment.

There are a lot of questions to answer, and creating side-by-side comparisons of solutions will help. Use this information to help prioritize your needs so that when you start evaluating solutions, you know where to draw the line. Whether to leverage assets or to meet space challenges, here are a few things to consider:

1.  Choose mobility for larger quantities of devices

With wide casters for easy moving across multiple surfaces, and storage to house multiple devices at a time, a charging cart is your best bet. Plus, it can easily be rolled into a closet to be locked up for the night. Here are some questions to think through cart options:

  • Will the devices be used exclusively in one class or will they be shared across the building?
  • Will they be stored by the teacher in the classroom or should they be housed in the Media Center or IT manager’s office?
  • Is it important to be able to visually check whether a device is plugged in properly and charging?
  • Is it secure? Will the locking mechanisms deter theft?

Choose fixed or desktop options for small quantities 

If you need to only manage a small number of devices, look for charging stations that can either be mounted on the wall or will sit on a desk or countertop. Take into consideration the following:

  • Does it offer a low profile to help avoid interfering with flow of students or staff around the room?
  • Consider the size of charging slots if the devices have cases; not all charging systems are created equal
  • Can the unit scale if class or device requirements grow?
  • Is security an issue? Do you need to lock up the device or is it safe to leave them in an open environment?
  • Ease of access to device is important, look for units that make device insertion and retrieval a snap

3.  Also important, choose safety!

Whether rolling out 20 devices or 1000, don’t forget the electrical requirements. Look for products that are UL labeled for the whole unit, not just the components. Charging station that have been designed to be a safe product requires redundant safety features, special abuse tests; both component and full system level certifications to all government standards is ideal when used in public places such as schools. Whether adults are the only ones interacting with the unit, or if students engage with it too, look for products that are rugged and suit the environment where they are being placed. Learn more about safe product design.

IMAG0455It’s fascinating to watch where the future of classroom technology is going. 360° classrooms, sit-stand learning environments, no barriers cyber-education…each new adoption faces its challenges. Being prepared means doing your homework ahead of making a purchasing decision. When you do integrate that new solution and it’s a winner for staff and students give yourself a gold star or take an Instagram selfie—some IT geekery is allowed!

Why We Need to Sit AND Stand

It isn’t enough to have a standing desk. You need the option to sit and stand throughout your day.

A few days ago I read a post on Hacker News from Mikael Cho the founder of ooomf declaring why he killed his standing desk

From his post I gleaned these reasons Mikael killed his standing desk:

  • Standing for long periods caused him pain
  • This pain distracted him from his work
  • His standing desk forced his body to take breaks when his brain wanted to work
  • He couldn’t stay ‘wired in’ and focused while standing

Mikael also mentioned the following items related to standing, productivity, exercise, health, and lifestyle:

  • His standing desk helped him stay focused during certain tasks like answering email
  • Sitting isn’t bad. It’s sitting for long periods of time without movement that’s the killer
  • When we don’t move, our risk of cardiovascular disease increases and our blood circulation drops
  • A standing desk may be one way to solve the sitting problem but it doesn’t solve the inactivity problem
  • In the book Blue Zones, longevity was linked to regular, low intensity physical activity
  • One community in Okinawa, Japan has one fifth the risk of colon and breast cancer and lives seven years longer than the average American. In their culture, people sit on the floor, causing them to get up and down thirty to forty times per day

Our mission at Ergotron is to offer high quality sit-stand workstations at an affordable price so that you have the option to sit or stand while you work.

The problem with Mikael’s desk is that it was a $22 standing only Ikea hack that didn’t offer the option to sit without re-configuring your technology. In this limited configuration, transition between standing/sitting is a productivity obstacle.

Having the option to easily sit or stand is critical to a great user experience.

Over the years since I first started using a sit-stand workstation I encountered many of the same issues Mikael faced. My legs got tired. I needed to sit to focus or get into flow mode. I found myself more productive standing going through email but needed to sit to get ‘into’ writing. Some days are different than other days. Some days I stand most of the day, other days I sit most of the day. Most days I am up and down, transitioning more than 10 times.

When at a desk for 6-8 hours a day, simply taking a break and standing for an hour to go through some emails relieves my muscle and joint stiffness.

With my WorkFit-D, using a single hand I can transition from sitting/standing while maintaining creative flow without re-configuring my screens, keyboard, or mouse.

But don’t kill your hack yet!

Are you like Mikael Cho, ready to kill your hacked standing desk? I say wait. Consider what a WorkFit configuration experience might do for you. Maybe a WorkFit D with the Dual Side-by-Side LX Arm configuration.  What, you’re a Macbook user? Think about the WorkFit-P for Apple. Whatever your scenario, we’ve got a sit-stand configuration to suit your style.

And if Mikael is reading this, I have an offer for you. You can find me at @solson.

(Infographic) Nursing Challenges and Changes

While nurses represent the majority of the U.S. healthcare workforce and are on the front lines of the industry’s radical transformation, they face many daily challenges. Nurses are responsible for quality care and patient satisfaction, yet they continue to spend more time interacting with technology and potentially less and less time actually providing care to patients, making it harder to provide outstanding care.

Nurses went into the profession because they wanted to take care of people. In this world of technology they are spending up to 35% of their day doing documentation. This infographic looks at ways that they can make that 35% more tolerable and reduce or combine documentation time with patient interaction (triangle of care).

Nursing Challenges and Changes_Infographic

We believe that if we can provide equipment to relieve physical burdens, solutions to technology problems and broadband telemedicine to alleviate the widespread nursing shortage, the healthcare industry and nurses in particular will be better positioned to do the job they are meant to be doing- providing quality care to patients.

[video] New WorKFit workstations designed for Apple users

Safe Product Design: Products that contain AC power may be dangerous!

  • What percentage of user injuries can be caused by my product?
  • How many fires are acceptable in a hospital or school?
  • Is it acceptable to allow user injuries if they don’t read the manual?

These are questions faced by companies designing electrical products for public use. The answer leads to vastly different actions by their engineering teams. They have to decide whether the goal is 0.01% or 0. And the actions one takes to achieve 0 are far more extensive than it is if a low rate of injury is allowable.

Designing a truly safe product requires redundant safety features, special abuse tests, both component and full system level certifications to all government standards. Products that contain AC power or have the potential to cause physical injury or death. When used in public places such as hospitals and schools, they have the potential to be exposed to non-technical and non-experienced users. A higher level of safety therefore applies, and OSHA has extensive requirements defined for almost any such product. 

However, you would also be surprised at how frequently companies get away with unsafe design practices and simply don’t bother to meet the regulatory standards defined by OSHA.  In our business, we have several competitors offering computer carts with battery power systems that are not certified to the OSHA-required standard of UL-60601-1. You should be aware that cost and schedule conscious suppliers may feel pressure to deliver products without the legally required certifications since it may cost tens of thousands of dollars and add months to the development schedule.

Skipping certification means skipping crucial fire safety, electrical safety, EMI and mechanical safety testing. We have tested many competitor products and have seen inadequate ground paths (which could cause shocks), lack of flame retarded plastics around high power components (fire hazard), small gauge wire with inadequate strain relief (fire and shock hazard), improper thermal systems (fire hazard), pinch points, and many other serious problems in products publicly available for sales into hospitals.  All these safety issues are possible even if the product is constructed of UL-approved components.

To be a good consumer and ensure the highest safety standards of the products you adopt, please be aware of the following misleading marketing statements. The only thing you know for sure if you see these statements, is that the product is NOT certified to the proper standard.

  • Tested to UL Standards
  • Designed to UL Standards
  • Constructed of UL Components

These statements may indicate that the system has been tested and failed, the system was not completely tested, or the system was not tested at all! These are not satisfactory answers and should be explored further to determine if full UL certification truly exists.

There is a simple way to tell if a product meets certification requirements–it will have a UL or other regulatory sticker on the outside of the product.

Certification Label

“UL Listed” or “UL Certified” verbiage in sales and marketing literature means a UL sticker and certificate have been earned (like the one shown here). These products have met the OSHA requirements. You can feel confident you and all that come in contact with the system will have the safest possible experience.

If you are responsible for purchasing electrical products for public use, you need to put pressure on manufacturers of non-certified products. These products are not safe for you to purchase and expose to your employees. 

Safe products are your right, and your responsibility, whether you are a designer, manufacturer, or purchaser.

Tablets, tablets, tablets…the main story at FETC in FL

Bob Hill, North America & EMEA Channel Marketing Manager @ Ergotron

From what I heard at FETC in Florida, show attendance was up over last year. Ergotron education products were placed in the CDWG, Dell, GovConnection and SHI International partner booths, but the one product that was garnering the most attention? As you might guess, Ergotron’s Tablet Management Cart (TMC). 

It is evident that tablets are just now hitting a critical mass and acceptance by IT directors within schools. These teams are now seriously considering large rollouts, or have just purchased fleets of tablets. In many cases, it is a brand new venture for them and there is some education required to learn how to logistically manage them. 

Over and over again I heard, “We just bought 2,500 iPads…” Or, “We are looking at rolling out tablets to all of our students…” 

These conversations were great and very invigorating, often encompassing the larger tablet ecosystem:

At this point, schools already seem to know whether they are going the route of school-owned devices or bring your own device (BYOD) or a hybrid of both. BYOD makes for a nice buzzword, but is not the clear winner yet. 

In our research we knew how the Tablet Management Cart fit with schools that own and manage their own USB-charging devices, but I also learned that our 16-tablet stand-alone modules have a really nice fit in BYOD environments.

The example I heard several times is that the module can be used as a charging station in a library or media lab setting in which a student could securely hand their personal USB-charged device to a librarian behind a counter who would then “coat check” it for the student.

Here are the Tablet Management Cart features most attendees were excited about, FYI:

  • USB tablet/device charging cart
  • Small and agile (multiple times: “Oh, it’s so cute.”)
  • Charging technology (contrasted against timer-based)
  • Mass syncing (only pertained to iPad audiences using iTunes)

We will be blogging more about tablet adoption in schools. Having a clean understanding of mobile device management software can help accelerate adoption/acceptance of mobile devices whether school-owned or BYOD. Is your school heading toward tablets?  We’d love to hear more about your experience.

Goldilocks and the Three Chairs or What Size Bear are You?

Carrie Schmitz, Ergonomics Advocate and Engineering Publications Manager @ Ergotron

measuring-stick-3-bears-002If ergonomists were looking for a mascot, my vote would go to Goldilocks−yes, I mean the blonde chick with a poor sense of boundaries. I’ve been working in the field of ergonomics for more than 10 years, and lately, I’ve begun to feel a certain kinship with the story-book character from my childhood days.

Let me explain: a few months ago I was helping a colleague assess the ergonomics of her work station; she had recently moved to a new department, and was suffering from neck stiffness and pain. After a taking a few measurements, I was able to verify that her desk and chair were set too high for her stature. Once the work surface was lowered, I invited her to try out a variety of office chairs, and a few minutes later I heard her exclaim, “This one’s just right!” that’s when it hit me: Goldilocks is all about ergonomics.

You know how the story goes: our heroine wanders into the house of the three bears while they’re taking a walk in the forest and proceeds to break several rules of etiquette along with poor little baby bear’s favorite chair.

But note, in the midst of this mad behavior, there was also method: just like a professional ergonomist, Goldilocks worked with a set of Standards!

Using herself as a subject, Goldilocks determined the suitability of the objects she encountered in the three bears’ home in much the same way a human factors specialist (another term for ergonomist), tests products: that is, empirically, through observation, experience and experimentation.

Moving from room to room, she established the safe temperature for eating porridge, gauged her chair size as it corresponds to either small, medium or large ursus horribilis, and put her stamp of approval on what she judged to be the most comfortable mattress for a mid-morning snooze.

In the real world ergonomists and human factors professionals work with hundreds of different human measurements compiled into tables of Anthropometric data that help shape our understanding of human physical variation and ultimately form the basis for decisions that affect every area of human experience and endeavor.

manikin-scaleTake for example Ergotron. We manufacture mounting solutions for flat computer equipment, so we need to know how high a screen should be placed in relation to the keyboard, to ensure the safety, comfort and productivity of the computer user. A measurement which depends on the distance between the user’s eye and elbow.

But how does one define the term “user”?

By referring to an Anthropometric table, where data has been organized by gender, size and age, our designers know exactly what portion of the population to target. In some cases, a product will be designed to meet a range of sizes from the 5th percentile adult female to the 95th percentile adult male. If the product is meant to be used by school kids, the minimum and maximum heights are tailored accordingly.

Designing products that are universally acceptable is a daunting challenge for manufacturers, and ergonomists pay special attention to factors that might cause shifts in the Anthropometric data. The growing number of obese individuals in western society, has caused ergonomists to reassess the design of office chairs, and question the application of the Body Mass Index, a mathematical formula used by health professionals that takes into account both a person’s height and weight.

One of the earliest applications of anthropometry in Europe made it possible for law enforcement officers to identify criminals by body type or finger prints. NASA and the United States military in general, are major players in the field of ergonomics and human factors.

bear-scaleTheir research has resulted in dozens of inventions that have become part of our daily life such as cordless power tools, protective sports gear, “space age” fabrics that regulate body temperature and more recently, a kitchen appliance that functions both as a refrigerator and an oven−something that might have come in handy at the three bears’ house!

As for Goldilocks, I admire her relentless curiosity and the presence of mind she demonstrated in strange surroundings. If asked what she learned from the experience, I imagine she might say, “I’m a size Mama Bear−not too large and not too small. What size bear are you?”

That’s “THE END” of this story. More to come on what ergonomics means in the world of work.

Digital Immigrant as 21st Century Classroom Teacher


Dave Sanders, Director, Roadmap Innovation – Education & Healthcare @ Ergotron


Last month, I had the humbling experience of walking a mile in the shoes of today’s teacher…sort of (I’ll explain the qualifier in a bit).  You see, I was responsible for a session at our annual sales meeting during which I was to train the sales team on our product offering and message for K-12 and Higher Education customers. 


And with overzealous confidence, I declared to my peers, “If I’m going to train the team on how our products can serve as the platform for the 21st Century Classroom, I’m going to do it Smart Classroom style”.  Easy enough, I thought. 


Wrong!  I had forgotten that I am a Digital Immigrant.


I quickly came to appreciate how daunting it can be for a Digital Immigrant Educator to step out of the old school and into a 21st Century Classroom.  


Teaching in a Smart Classroom requires all of the usual preparatory effort – what content to be delivered, how to engage and motivate students, etc.  It also introduces a very time-consuming stressor:  how to put a bunch of new technology to productive use without losing the lesson in the process, or worse yet looking just plain foolish? 


After all, one of my daughters reminded me a couple of days ago how wide the tech-divide is between Digital Immigrants and Digital Natives (Marc Prensky offers up more insight on this divide at


I had just sent her a text message containing “u” for you and “fb” for Facebook.  I thought I was both digitally cool and efficient.  Wrong again!  She said, “Only parents shorten words like that.”  I guess kids don’t need to, given their native ability to rifle off one-handed text messages on a cell phone keypad while playing a video game with their free hand.


So back to my “class.” The 90-minute agenda included a PowerPoint-supported training presentation, a small group breakout segment to discuss homework enabled by Google documents, some Excel spreadsheet data review, a guest lecture by one of my colleagues on education technology, an awards session facilitated by a document camera (to display the various awards to the whole class), and some mp3 audio content thrown in for spice. 


This was all delivered 21st Century Classroom style to about 60 “students” using a convertible tablet pc and the document camera mounted on a powered mobile teaching platform, with wireless KVM technology to throw keyboard, video and mouse action to a projector and screen at the front of the room.  Content was also thrown to two large-format LCD displays on mobile carts at mid- and back-room to ensure view-ability and facilitate collaboration during the breakout segment.


Needless to say, I spent a great deal of time preparing for this session, as did an especially tech-savvy colleague who helped make all the technology components talk to each other.  This led me to think of the significant time and energy that teachers must invest in education technology training as they move into a Smart Classroom setting. 


In the end, our smart classroom efforts paid off.  Everything worked properly and the session was productive.  This brings me back to the qualifier I made at the top of this post.  I was “teaching” a group of sales professionals – a tough audience in its own right – but undoubtedly not as challenging as connecting with a room full of Digital Natives!


As I travel the US this year meeting with K-12 and Higher Education professionals, and our technology integration partners who serve them, you can bet that I will be drawing upon insights gained from this walk in a teacher’s world to help them navigate the technology jungle. 


If I don’t find you first, look me up!
