Choosing a GaN Charger in 2026: A UK Buyer's Guide to Powering Your Devices
The days of carrying a separate, bulky power brick for every device are numbered. If your bag is weighed down by a collection of chargers for your laptop, phone and tablet, you've likely felt the inconvenience. Modern technology demands a more streamlined solution, and that solution is increasingly found in GaN chargers.
Gallium Nitride (GaN) is a semiconductor material that is changing the game for charging technology. It's more efficient than the traditional silicon used in most power adapters, allowing manufacturers to create chargers that are significantly smaller, lighter and run cooler, all while delivering more power.
This guide is designed to help you navigate the options. We will outline the key features to look for in a GaN charger and present a few carefully selected recommendations to help you find the right fit for your devices and lifestyle.
How to Choose the Right GaN Charger
Selecting the right charger involves more than just picking the one with the highest number on the box. Here are a few practical points to consider to ensure you get a device that meets your needs.
1. Understand Wattage and Power Distribution
The total wattage (W) of a multi-port USB charger indicates its maximum power output. However, this power is often shared between the ports. For example, a 100W charger with two devices plugged in might deliver 65W to a laptop and 30W to a phone. Look for chargers that support USB-C PD (Power Delivery), the modern standard for fast charging everything from smartphones to high-performance laptops. A good laptop and phone charger will intelligently distribute power to charge all connected devices efficiently.
2. Check the Number and Type of Ports
Consider the devices you use daily. A modern setup will benefit from multiple USB-C ports, as this is the prevailing connection standard. However, having at least one USB-A port can be useful for charging older accessories like wireless mice, keyboards or power banks. A versatile fast wall charger should offer a practical combination of both to cover all your bases.
3. Prioritise Portability and Safety
One of the primary advantages of GaN technology is its compact size, making these chargers an excellent choice for a travel charger. When comparing options, look at the dimensions and whether it has features like foldable prongs for easier packing. Most importantly, ensure any charger you purchase is UKCA certified. This mark indicates that the product complies with UK safety, health and environmental protection standards, giving you peace of mind when plugging in your valuable electronics.
Our Top GaN Charger Recommendations for 2026
We've analysed the market to find chargers that offer a great balance of performance, portability and features. Here are our recommendations for 2026.
ACEFAST A79 USB-A/ USB-C Charger - Black
Why It Stands Out: The ACEFAST A79 is a compact and efficient charger perfect for everyday use. Its dual-port design and support for multiple fast-charging protocols make it a versatile companion for powering up your essential devices without taking up much space.
Pros:
- Advanced GaN Technology: Delivers efficient charging in a small, cool-running package.
- Dual-Port Charging: Features a 20W USB-C PD port and an 18W USB-A Quick Charge port.
- Broad Compatibility: Supports PD, QC, AFC (Samsung) and FCP (Huawei) fast-charging standards.
- Certified Safe: Fully UKCA and CB compliant with built-in overvoltage and overcurrent protection.
Who is it for?: This charger is ideal for smartphone and tablet users who need a reliable and portable power source for their daily commute or to keep in their work bag.
Anker Prime, USB-C 3-Port GaN Charger, 100W Fast Charging, Black
Why It Stands Out: For those who need serious power, the Anker Prime 100W is a true workhorse. It can deliver a full 100W from a single USB-C port, enough to fast-charge even demanding laptops, while its three ports allow it to function as a central charging hub for all your tech.
Pros:
- High-Power Output: Provides a total of 100W, capable of charging three devices at once.
- Maximum Single-Port Power: A single USB-C port can output a full 100W, ideal for power-hungry laptops.
- Travel-Ready Design: Features a compact body and foldable prongs for excellent portability.
- Three-Port Versatility: Equipped with two USB-C ports and one USB-A port to handle a modern device ecosystem.
Who is it for?: The power user. This is for professionals, creatives and students with a high-performance laptop (like a MacBook Pro 14") who want a single charger to power their entire setup.
Anker Prime, USB-C 3-Port GaN Charger, 67W Fast Charging, Black
Why It Stands Out: This model strikes an excellent balance between power and extreme portability. According to Anker, it is significantly smaller than a standard 67W laptop charger, making it an outstanding choice for those who prioritise minimising weight and bulk without a major compromise on charging speed.
Pros:
- Ultra-Compact Form: Exceptionally small and light, making it a superior travel charger.
- Sufficient Power: Delivers up to 67W to a single device, perfect for MacBooks, Ultrabooks and tablets.
- Flexible Charging: With two USB-C ports and one USB-A port, it can power three devices simultaneously.
- Advanced Safety: Features Anker's ActiveShield 2.0 system for continuous temperature monitoring.
Who is it for?: Frequent travellers and mobile professionals who need to power a standard laptop (like a MacBook Air or Dell XPS 13), a phone and an accessory, all from one tiny, powerful brick.

Frequently Asked Questions about GaN Chargers
1. What is a GaN charger and is it better? A GaN charger uses Gallium Nitride, a semiconductor material that is more efficient at conducting electricity than the traditional silicon used in older chargers. This higher efficiency means less energy is lost as heat, allowing manufacturers to build chargers that are smaller, lighter and more powerful than their silicon-based counterparts. For users with multiple devices, they are generally a better choice due to their size and power capabilities.
2. Can I use a 100W GaN charger for my phone? Yes, you can. Modern chargers and devices are equipped with smart charging technology. A USB-C PD charger communicates with the connected device (like your phone) to determine the maximum power it can safely accept. The charger will then only supply that amount of power. Using a high-wattage charger will not damage a low-wattage device; it will simply charge it at its fastest supported speed.
3. Do GaN chargers get hot? All chargers generate some heat as a natural byproduct of converting AC power from the wall to DC power for your device. However, because GaN technology is more efficient than silicon, GaN chargers lose less energy as heat. This means they typically run cooler than traditional chargers of a similar power rating, especially under heavy load. Always ensure your charger has adequate ventilation during use.
