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.

Taking a Literal Stand against Childhood Obesity

As September, and National Childhood Obesity Awareness Month, draws to a close, it’s important that we all take a moment to reflect on where we stand thus far in the campaign against childhood obesity, and if we’re doing all we can to win the fight.

One of the key aspects of this epidemic is actually right in front of our noses: our children’s schools. And while initiatives to improve lunch programs is an important component to this campaign, nutrition alone is not going to go the whole distance to improving children’s health. Increasing physical activity and reducing sitting time are just as crucial.

There’s been growing concern that children are defaulting into sedentary lifestyles (i.e. long hours spent in front of the television, computer and playing video games) – what we should also be considering a threat is the amount of time spent sitting in today’s classroom.

In total, children likely spend over 6 hours a day seated in school. A recent study in the United Kingdom revealed greater than 50% of the seven- and eight-year old children sampled were sedentary for greater than 6.4 hours/day – with sedentary behavior comprising greater than 65% of their waking hours.

Teachers and schools, in order to promote better health and academic performance, are taking a stand – quite literally – deploying Ergotron’s LearnFit™ Standing Desks in the classroom. These desks incorporate more natural movement throughout the day. Access to the desks can help children burn more calories during classroom instruction, especially when other active opportunities are disappearing with school budget cuts – child development research shows that movement and learning are integrally linked.

The facts about Why Classroom Movement Gets an A+:

  • The part of the brain that processes movement is the same part of the brain that processes learning.
  • Exercise boosts brain power.
  • Movement can be an effective cognitive strategy to strengthen learning, improve memory and retrieval and enhance learner motivation and morale.
  • Studies indicate that concentration is lost after the fourth lesson of the morning, but challenging the vestibular or balance system has a tremendous effect on brain activity, renewing the ability to concentrate.
  • Activities that stimulate inner-ear motion, like swinging, rolling and jumping significantly improve attention and reading.
  • Physical activity increases blood flow, and hence oxygen, to the brain; oxygen is essential for brain function.

The preliminary results have been overwhelmingly positive in discovering more about the effects of prolonged sitting – in school and at home – on children’s overall health and well-being (see Belle Terre Elementary the first school in the United States into their second season with a classroom fully-equipped with our LearnFit standing desks).

What’s happening at ISTE 2014?

JoeyD_BelleTerreElementary

Ergotron is featuring presentations in the booth (3326) each day of ISTE! Here, Joey DiPuma, IT manager for a Florida-based public school system, is speaking with attendees about his experience in Spring 2014 integrating a standing desk classroom into a school in their system, Belle Terre Elementary, using Ergotron’s new LearnFit™ Standing Desk.

Through his recognition that the classroom environment should be capable of matching the level of achievement currently attained through the use of one-on-one devices, he worked with Ergotron to convert a classroom with the goal to increase student achievement through traditional and innovative approaches to education.
