UL-Certified vs. Generic AC Adapters: What Schools Need to Know

UL-Certified vs. Generic AC Adapters: What Schools Need to Know

Why UL-Certified AC Adapters Matter for School Chromebooks

Not all AC adapters are created equal when it comes to keeping your school’s Chromebook fleet powered and protected. While generic adapters may look similar and come at a lower price,  their risks far outweigh the short-term savings. From overheating to potential fire hazards, the consequences of using uncertified chargers can be costly and dangerous.

That’s why more schools are making the switch to UL-Certified AC adapters. Backed by rigorous safety testing and trusted by IT professionals, UL-Certified adapters deliver consistent performance, long-term reliability, and peace of mind for educators.

The Hidden Dangers of Generic Adapters

Generic or off-brand AC adapters often bypass essential safety certifications and quality standards. While they may appear similar to name-brand products, they’re typically built with lower-grade materials and little oversight—making them a risky choice for schools.

These unreliable alternatives can:

  • Overheat during use

  • Cause short circuits or sparks

  • Damage Chromebook motherboards

  • Become fire hazards in classrooms

  • Void your device warranties

When powering student devices, cut-rate chargers aren’t worth the gamble. A single failure can disrupt learning, and a widespread issue can create costly tech emergencies.


What Does UL Certification Mean?

UL (Underwriters Laboratories) is a globally recognized safety science organization that tests and certifies products based on strict safety and performance criteria. When an AC adapter is UL-Certified, it means it has passed:

  • Electrical safety tests

  • Fire resistance standards

  • Durability and environmental stress testing

Unlike generic brands that cut corners, UL-Certified AC adapters are built to withstand daily classroom use and deliver consistent, safe charging. UL’s mark is your assurance that a product is compliant and classroom-ready.

The History of the Laptop: An Essential Guide to Laptops, Notebooks, and Chromebooks

The History of the Laptop: An Essential Guide to Laptops, Notebooks, and Chromebooks

For 1:1 education technology initiatives, it’s important to understand your options when it comes to mobile devices. Chromebooks are a popular choice for many education technology programs. With so many industry terms flying around and sometimes used interchangeably, it can cause your head to spin making it difficult to choose the right device for your ed tech program. We’re breaking down the foundational and influential history of the laptop, and ins and outs of each type of device.

What is a Laptop?

In the simplest terms, a laptop is a portable computer. It was created as the compact and portable version of a desktop computer.

The History of the Laptop

All roads lead to the laptop. Arriving on the scene in 1981, the Osborne 1, of Osborne Computer Corp., is widely regarded as the first laptop. It’s a far cry from the sleek and light laptops we see today. Weighing in at a hefty 24 pounds with a price tag north of $1,500, the Osborne 1 featured a 5” screen, two floppy drives, and bundled software. Introduced as an ideal office solution for business execs on the move, this model never saw any type of real success.

Fortunately, though, Osborne Computer Corp. was not the only computer company with an interest in the advent of the portable computer. Epson, Microsoft partnered with Radioshack, and IBM all released laptop computers by the mid 1980s. Microsoft was the first to feature a laptop with an LCD display.

Various computer powerhouses continued to introduce new laptops and integrated technologies in the late 1980s into the 1990s. Most notably:

  • Compaq released their version of the laptop in 1988
  • Apple released the first portable Macintosh in 1989
  • Microsoft released mouse and trackball technology for laptops in 1991
  • IBM released the first ThinkPad in 1992

In 2008, laptops eclipsed desktops in sales for the first time. This trend has continued since, with laptops consistently outselling desktop models yearly. Today, laptops are still very popular despite decreased net sales for personal computers. This decrease is due in part to the increased popularity of smartphones. Although net sales have decreased since 2012, laptops are on the uptrend, with laptop sales increasing since 2016. In 2019, 166 million laptops were sold worldwide.

Traditionally, laptops use the Windows or Apple operating systems and support Microsoft Office applications.

What is a Notebook?

A notebook computer, which is typically a smaller, slimmer, and lighter laptop, was first introduced in the late 1980s by NEC. It was a similar in size to a laptop but weighed in at mere five pounds. By the early 1990s, Compaq and Apple had both released versions of the notebook as well.

Generally, notebooks are less expensive than laptops, ranging in price from $150 to $400.

A type of notebook, the ultrabook, was first introduced in 2011 as Intel’s answer to Apple’s thin and light MacBook. They are a high-end notebook that use low-power Intel Core processors, solid-state drives, and unibody chassis to create an ultra-light computer without sacrificing battery life.

Traditionally, notebooks use the Windows or Apple operating systems and support Microsoft Office applications.

What is a Chromebook?

First introduced in June 2011, a Chromebook is a type of laptop that uses the Linux-based Chrome OS as its operating system. Chromebooks are specifically designed to use the Google Chrome browser and most activities occur online via Chrome. This includes word processing, creating spreadsheets and slideshows, note taking, etc. These docs are automatically saved to cloud storage via Google Drive.

One of the biggest differences between a laptop and Chromebook is security. There is no need to purchase virus protection because it is built into the Chrome OS. This built-in protection is regularly updated via the Chrome OS’ auto updates. This makes Chromebooks nearly impervious to viruses and malware.

Closely related to this is the Auto Update Expiration (UAE, formerly known as EOL). This is the date that the Chrome OS will no longer support regular auto updates for software and security patches, as well as technical support. The Chromebook will still be functional, but it would be risky to use the device past this date.

Don’t let this deter you—AUE allows Google to focus on providing the best and most secure updates for the newest and most recent hardware. Additionally, AUE date far outweighs the average shelf life of four to five years for a traditional laptop. In fact, AUE gives Chromebooks a shelf life of six-and-a-half years to eight-and-a-half years from the date of launch.

Another difference between a laptop or notebook versus a Chromebook was storage. Chromebooks rely on cloud-based storage for most applications and data, as opposed to internal storage on the machine itself. However, cloud storage is common for any laptop today, whether it’s powered by Microsoft (OneDrive) or Apple (iCloud) operating systems. Various cloud storage platforms, like Dropbox and Google Drive, can also be used for older laptops where cloud storage is not as common.

Chromebooks are a popular choice for ed tech program because they are affordable, fast, secure, require little maintenance, and collaborative.
