When Technology Becomes Personal: A Look into Design Philosophy

Technology is often developed with a purely functional goal in mind, but some companies approach their products from a more personal and human-centered perspective.
This is evident in TESSAN’s team statement: “Our journey in creating travel adapters wasn’t just business… it was personal.”
Such a philosophy is reflected in device designs that prioritize user comfort and a wide range of practical needs.

Real-World Challenges in Using GaN Chargers Globally

While many admire GaN technology for its power and compact form factor, real-life usage has revealed a key shortcoming:
Incompatibility with power outlets in countries like China, India, and across the European Union.
This challenge isn’t about performance or efficiency—it stems from the global diversity of electrical infrastructure and plug standards.

Universal Compatibility: The Missing Link Some Devices Finally Got Right

The release of newer devices (used here as a case study) has bridged this gap.
The issue wasn’t the strength of the charger, but its adaptability to diverse real-world scenarios.
A device that includes numerous ports and supports everything from laptops to wireless earbuds reflects a major leap in design thinking.

The Evolution of GaN Technology: From Concept to Complete Solutions

The secret behind this leap in performance and versatility lies in the continued advancement of GaN technology.
Once seen merely as a more efficient alternative to silicon, GaN has now become the foundation of a new era in charging:
Chargers that are more powerful, smaller in size, and smarter in energy distribution and safety features.

What Is GaN Technology—and Why Does It Make a Difference?

For those unfamiliar with it, GaN—or Gallium Nitride—represents a breakthrough in semiconductor technology.
While most modern electronic devices still rely on traditional silicon-based chips, GaN has emerged as a more efficient and capable alternative.

The Silicon Problem: Limited Efficiency Under High Demand

Silicon has been the backbone of technological progress for decades, but it comes with clear limitations:

• The more power a device needs, the larger the silicon chip becomes.
• As size increases, so does heat output.
• More heat means more energy loss—and lower efficiency.

These issues explain why traditional laptop chargers are so bulky and not exactly travel-friendly.

The Shift to GaN: A Game-Changer

With GaN, it’s possible to deliver the same—or even greater—power output in a smaller size and with better energy efficiency.
This shift has made it possible to produce compact chargers that can deliver 100W or more,
without compromising on performance or safety.

Some of the latest models have even achieved outputs of up to 205W in a device that fits in the palm of your hand—
a feat that would have been hard to imagine just a few years ago.

Multi-Device Charging Without Compromise: How 205W Makes a Real Difference

Reaching a charging capacity of 205W isn’t just an impressive number—it translates into real-world power: the ability to charge two laptops simultaneously without sacrificing performance or speed.
This type of charger is ideal for users who rely on multiple high-power devices at once—whether for work or family use.

Smart Power Distribution: How Energy Is Managed Efficiently

What sets some modern chargers apart—especially those supporting PD 3.1 technology—is their ability to intelligently assess each device’s power needs and distribute energy accordingly.
Instead of sending a fixed amount of power to each port, smart circuitry ensures:

• Larger devices (like laptops or tablets) receive the highest output—up to 140W on a single port.
• Smartphones get moderate power for safe, fast charging without overheating.
• Smaller gadgets like watches or earbuds are given low but sufficient energy—without draining the overall power supply.

Port Variety: Full Support for Families and Mobile Devices

Having 7 USB ports (5 USB-C and 2 USB-A), plus a universal AC outlet, makes this charger ideal for a wide range of situations:

• Your laptop—and someone else’s.
• A tablet or a Nintendo Switch.
• A travel kettle, electric shaver, or hair dryer.
• A power bank, smartwatch, or wireless earbuds.

This variety doesn’t just mean more devices—it means fewer chargers to carry, which is crucial for both travel and daily work.

Universal Design: One Charger for Every Continent

One of the biggest challenges travelers face is the variation in electrical outlets from one country to another.
That’s why the universal design of some modern chargers provides a practical and straightforward solution.
A built-in sliding mechanism allows users to select the appropriate plug type for their region—without needing separate adapters.

Ready for Over 200 Countries

Supporting a wide range of plug types makes these chargers compatible in more than 200 countries worldwide.
This eliminates the need for travelers to worry about whether their devices will work with local standards, offering true flexibility and peace of mind during international trips.

Compact Size & Lightweight: Perfect for Travel Bags

Size and weight are critical when choosing any travel accessory.
Typical dimensions for this type of charger are:

• Length: 3.9 inches
• Width: 2.1 inches
• Depth: 2.2 inches
• Weight: 326 grams (around 0.7 lbs)

This makes it easy to carry in a backpack or laptop bag without adding noticeable bulk.

Safety First: Thoughtful Design and Quality Materials

Performance aside, safety is equally important.
That’s why these chargers use flame-retardant materials—such as advanced polymers—and feature a set of built-in protections within the internal circuitry, including:

• Overheat protection
• Overvoltage protection
• Protection against overcharging smaller devices

These safeguards enhance the reliability of the charger in both work and travel settings, giving users extra peace of mind when powering multiple devices simultaneously.

A Real-World Comparison: Do Multi-Port Chargers Actually Save You Money?

From an economic standpoint, multi-functional chargers can be a smarter long-term investment.
For example, purchasing a single charger with 8 ports could eliminate the need to buy 8 separate chargers—reducing both cost and clutter.

Here’s a simple comparison to put things into perspective:
