What Is a GaN Charger? 5 of the Best GaN Chargers You Can Buy

Are you sick of lugging around multiple chargers for all of your devices and hate the fact that the giant batteries inside your phone and laptop seem to take forever to charge? If you answered yes, then you’re in for a treat. Say goodbye to the heavy, cumbersome charging brick and hello to the svelte, powerful GaN charger. Gallium Nitride chargers are the next step in charging technology. They are more efficient at converting power, which means there is less wasted energy.

What Does GaN Mean?

GaN stands for Gallium Nitride. It is a semiconductor used to convert energy to power in various electronics. Gallium nitride has been used in this capacity since the early 90s, most commonly as light-emitting diodes. For example, if you’ve ever owned a Blu-Ray player, the laser that read the discs was gallium nitride.

However, more recently, gallium nitride has been used as a successor to silicon, a semiconductor to charge the batteries found in many consumer electronics, including laptops and mobile phones.

What’s Wrong with Silicon Semiconductors?

Since the dawn of the first electronic equipment, engineers have been trying to figure out how to convert raw electricity to power as rapidly and efficiently as possible. In this conversion process, electricity that is not converted into power is wasted as heat.

For example, let’s go back to the 1950s and look at vacuum tubes. Not only were they large and expensive, they gave off a considerable amount of heat, indicating how inefficient they were. Next came transistors, which were smaller, cheaper and significantly better at converting raw electricity to useful power.

Eventually, silicon was widely adopted as the best semiconductor material. Silicon has excellent electrical conductive properties and is cheap to produce. Silicon was the standard bearer for decades, with engineers able to get better performance for even less money. Unfortunately, silicon has reached the apex of its efficiency. This means silicon has effectively hit a dead end, as it can no longer be improved. This is problematic in today’s world. Power efficiency requirements and environmental regulations are quickly outdating silicon semiconductors, as they can no longer keep up with modern demands.

How Do GaN Chargers Work?

Without getting too far in the weeds with technobabble, all semiconductors have what is called a bandgap. Essentially, this is how well a solid material can conduct electricity. Gallium nitride has a wider bandgap than silicon. As a result, gallium nitride chargers can handle higher voltages and higher temperatures than silicon. But what does that mean for the average consumer?

What Is the Advantage of GaN Chargers?

There are a number of advantages associated with using Gallium nitride over silicon-based chargers, with the biggest being efficiency. As we mentioned above, gallium nitride can handle higher voltages and temperatures compared to silicon. This is because GaN chargers are more efficient at converting raw electricity into usable power. As a result, they generate considerably less heat and less wasted energy.

Additionally, because there is less heat, the components of GaN chargers can be packed closer together. This means the charger can be much smaller than silicon-based chargers. Furthermore, gallium nitride is capable of conducting energy at higher voltages. An electrical current can pass through GaN much faster than silicon. Ultimately, this means your devices will charge faster with a GaN charger than a silicon one.

In summation, GaN chargers are more power efficient, significantly smaller and capable of charging your devices much faster than a silicon-based charger.

Are GaN Chargers Compatible with Multiple Devices?

Because GaN chargers are much smaller, they incorporate USB-C Power Delivery. in layman’s terms, USB-C Power Delivery is a fast charging protocol. It supplies increased levels of power compared to standard chargers. For example, USB-C PD can charge your device up to 70% faster than a standard 5W charger. Unfortunately, not every device is compatible with USB-C PD. However, iOS users will be pleased to know that iPhone 8 and later support USB-C PD, as well as many Android phones, tablets and even laptop computers. To find out whether your device supports USB-C PD, consult your user manual or manufacturer website.

Provided your device supports USB-C PD charging, you’ll also need to have a USB-C charging cable, as well as a USB-C PD wall or car charger. (For our picks of the best of the best, check out the next section.) There are a number of GaN USB-C PD chargers on the market – all at different price points. So which one should you get? It depends on how much power your device needs. Generally speaking, a larger device, like a laptop, would need a charger capable of delivering 30 – 100W. A tablet would need somewhere between 18 – 30W, whereas a cell phone would need anywhere from 18 – 45W. To ensure you get the right charger for your device, consult the recommendations of your device’s manufacturer.

GaN Charger Recommendations

Gallium nitride chargers can be found at retailers everywhere. From brick and mortars like Best Buy and Walmart to online retailers like Amazon, you will have no trouble finding them. However, there are many models to choose from, from a number of manufacturers. To help you pull the trigger on your new GaN charger, we’ve rounded up some of the best available today.

1. Anker Nano II

If you’re looking for one of the smallest GaN chargers available, look no further. The Anker Nano II utilizes GaN II technology, which benefits from a 20 percent increase in operating frequency. This means the charger is super small, while delivering 45W of power for only $40 (or 65W for $55). All while staying relatively cool.

Despite its diminutive size, the Anker Nano II is powerful enough to charge large devices like laptops, including the 2020 Macbook Air, Google Pixelbook, Surface Book 2, Dell XPS 13, HP Spectre Folio and more. The plug prongs fold up into the charging brick itself, making it ideal for travel.

2. Belkin Dual 68W GaN Charger

What if you have more than one device that can take advantage of super fast GaN charging? With the Belkin Dual 68W GaN Charger, you’ll be able to top up your laptop and your phone simultaneously. The charger features intelligent power-sharing technology that can detect the safest and most efficient charge to each device.

With an asking price of only $35 for 65W of power, this is one of the cheapest GaN chargers you can get your hands on. The cherry on top is that it boasts three charging ports: two USB-C and one USB-A. Granted, it’s from a lesser known brand, but with 4.5 stars out of 5 on Amazon, it’s definitely worth a look.

5. Anker PowerPort Atom III

The PowerPort Atom III from Anker is essentially the same as their Nano II. Both chargers deliver the same 45W of power, but the big difference is the design of the charger. While the Nano II is one of the best small GaN chargers available, it is still a charging brick. Add a USB-C cable to it, and the Nano II still juts out of the wall. The PowerPort Atom II does not have this problem and is cheaper at only $35.
