The future of fast charging: how do GaN USB-C chargers work?

​

Even more benefits of charging with USB-C

In the world of chargers, there is a new technology becoming increasingly popular: GaN chargers. But what makes these chargers so special, and why would you want to use one? In this blog post, we dive into the operation and benefits of GaN USB-C chargers.

What is GaN?

GaN stands for Gallium Nitride, a semiconductor material that operates more efficiently than the traditional silicon used in conventional chargers. This is because GaN has higher voltage resistance and causes less energy loss.

How does a GaN loader work?

With a traditional charger, a large portion of the energy is converted into heat (much like with an old-fashioned incandescent light bulb), which means more cooling is required and therefore the components must be larger. GaN chargers are much more efficient in energy transfer, meaning they produce much less heat and can be designed more compactly. This allows manufacturers to create more powerful chargers that are still much smaller and remain portable.

The benefits of GaN USB-C chargers

• Smaller size: because GaN chargers generate much less heat, chargers can be made smaller without compromising performance;

• Faster charging: GaN chargers support higher wattages (power) and can therefore charge devices much faster, especially in combination with system USB-C Power Delivery (PD);

• More efficient energy use: less energy loss means a lower electricity bill and a more sustainable solution;

• Reduced heat generation: this increases the lifespan of the charger (electronic components wear out faster due to higher temperatures) and makes it safer to charge devices at high power.
