That makes it useful in compact USB-C chargers and in some data-center, solar, vehicle and industrial power converters. Its benefits depend on the converter design: GaN is not automatically more efficient than silicon in every device, nor is it the right choice for every high-power job.
What GaN does in a power converter
GaN is a wide-bandgap semiconductor used as a high-frequency power switch. Switching devices control how electrical energy is converted—for example, from AC wall power to the DC power a laptop needs. GaN’s fast switching and potential for lower losses can let designers reduce the size of magnetic components and cooling hardware, improving power density: the amount of power delivered for a given size.
GaN and silicon carbide (SiC) are both established wide-bandgap options for high-voltage switching in DC-DC and DC-AC converters, according to a 2024 IEEE review. Their usefulness depends on the application’s voltage, power level, topology and design requirements; neither material is a universal replacement for silicon.
Where GaN is used
USB-C chargers for phones, tablets and laptops
Consumer chargers are the most visible GaN application. Because GaN can support compact, high-output designs, manufacturers use it in multiport USB-C chargers intended to power devices such as laptops and phones. Belkin describes GaN chargers as producing less heat than traditional silicon-based chargers. The semiconductor is only one part of the result, however: the charger’s power electronics, thermal design and load all affect its real-world performance.

Data-center and AI power supplies
Data centers use several conversion stages to deliver power from the facility’s electrical supply to computing equipment. GaN is being applied to AC/DC supplies, intermediate-bus converters and DC/DC point-of-load designs for high-performance computing. In these systems, power density and conversion efficiency matter because they affect equipment footprint and the amount of heat that must be managed. GaN and SiC can also appear in reference designs for these power systems.
Solar microinverters and battery storage
Photovoltaic inverters convert a solar array’s DC output into usable AC power, while battery inverters manage conversion between batteries and the electrical system. GaN can help reduce switching losses and magnetic-component size in suitable voltage and power ranges. Renesas, for example, publishes a single-stage GaN microinverter design for on-grid and off-grid solar.

The device topology and power level matter. GaN can suit some compact microinverter designs, while a higher-power string inverter may favor SiC. The material choice is an engineering decision, not a blanket rule for all solar equipment.
Electric vehicles and charging equipment
Wide-bandgap converters are relevant to vehicle electrification and EV charging. European Commission project work includes traction inverters, bidirectional onboard chargers and high-voltage/low-voltage converters. GaN is used in selected high-voltage ancillary and actuator applications, but that does not mean every production EV traction inverter is GaN-based. Vehicle power, voltage, reliability qualification and other design constraints influence component choice.

Industrial, automotive and communications infrastructure
Semiconductor manufacturers describe power-GaN platforms for industrial equipment, automotive systems, infrastructure and renewable energy. These are application areas where designers may use GaN—not evidence that it dominates each market. Whether it makes sense depends on the requirements of the specific converter and how GaN compares with silicon or SiC for that stage.
What the performance figures do—and do not—show
In its 2024 PECTA application study, the IEA 4E estimated more than 120 TWh in potential annual energy savings from wide-bandgap commercial power converters across the applications it covered. That is a modeled estimate for wide-bandgap technologies as a group, not measured savings already achieved and not a GaN-only total.

Navitas’s 2024 Form 10-K estimates that its GaN-based systems, compared with silicon-based systems, can deliver up to three times the power density, charge three times faster and save up to 40% energy. These are company estimates, not universal results for GaN devices or independent product-level measurements.
There is no single efficiency percentage that applies to every GaN charger. Results vary with load, topology, input voltage and thermal design, as well as the device being charged. GaN can enable a more efficient design, but the presence of a GaN switch by itself does not establish how much energy a particular charger saves.

How to choose a GaN charger for a laptop and phone
Match the charger to the devices and how you plan to charge them. A high headline wattage is not enough: check the output available to each port when multiple devices are connected.
| Charger option | What the cited product information establishes | What to check before buying |
|---|---|---|
| Belkin 65W dual USB-C PPS charger | Belkin specifies simultaneous MacBook and iPhone charging. | Confirm that 65W and the charger’s port power-sharing behavior meet your laptop’s requirements when both ports are in use. |
| Anker GaN charger families | Anker’s current collection includes 65W, 67W, 100W and 250W families. | Check the exact model’s sustained output, port allocation and supported charging protocols; a family wattage does not describe every port’s output during simultaneous charging. |
| UGREEN 65W Nexode GaN chargers | UGREEN lists multiport 65W options, including compact, travel-oriented designs. | Verify the particular model’s port sharing, plug format and fit for the laptop’s power requirement. |
Before ordering, check these details on the exact model’s current specifications:
- Laptop power requirement: Compare the charger’s sustained USB-C output with the laptop maker’s recommended adapter wattage.
- USB-C Power Delivery and PPS: Confirm support for the charging standards your devices use. PPS can matter for compatible phones.
- Multiport power sharing: Look for the output available per port when the laptop and phone are connected together, not just the maximum total wattage.
- Travel fit: Check the charger’s dimensions and plug format for your destination.
- Safety and support: Review the exact model’s safety certifications and warranty.

GaN versus SiC: which fits the job?
GaN and SiC are both wide-bandgap materials, but the choice is made for a particular converter stage, not by ranking one as universally better. GaN’s fast switching and power-density potential can suit compact converters and selected lower- or medium-power designs. SiC may be a better fit in some high-voltage, high-power applications, including certain string-inverter designs. Some high-power systems use hybrid GaN-and-SiC architectures.

Engineers comparing them need to assess switching frequency, voltage class, gate drive and protection, thermal path, isolation, electromagnetic compatibility, reliability qualification and total bill of materials. Silicon remains a lower-cost incumbent in many designs, so a material change is worthwhile only when the full system-level trade-off supports it.
