Is your desk cluttered with a tangle of cables and bulky plugs? Do you find yourself packing multiple chargers for a weekend trip—one for your phone, one for your tablet and another hefty brick for your laptop? This is a common frustration. The chargers that come with our devices are often slow, cumbersome and designed for a single purpose.
Fortunately, there is a more efficient solution. Gallium Nitride, or GaN, is a material that is changing the way we power our technology. A GaN charger can deliver high-speed power in a package that is significantly smaller and more efficient than traditional silicon-based chargers.
As the Joybuy Product Recommendation Officer, my role is to help you navigate the options. This guide will explain what to look for in a GaN charger and provide some practical recommendations to help you find the right model for your devices, whether you need a simple iPhone 15 charger or a powerful 100W laptop charger.
How to Choose the Right GaN Charger
Selecting the right charger involves more than just picking the smallest one. To ensure you get a device that meets your needs, consider these key factors.
1. Match the Power Output (Wattage) to Your Devices
The power output, measured in watts (W), is the most important specification. It determines how quickly your devices will charge.
- For Smartphones: Most modern smartphones, including the latest iPhones and Samsung Galaxy models, benefit from a charger with at least 20W to 30W for fast charging. A Samsung fast charger or a dedicated iPhone plug in this range can significantly reduce charging times.
- For Tablets and Small Laptops: Devices like the iPad Pro or MacBook Air charge efficiently with a 30W to 65W charger.
- For High-Performance Laptops: Power-hungry devices like a MacBook Pro or a Dell XPS require a 65W to 100W laptop charger (or more) to charge at full speed, especially while in use.
2. Count the Ports You Need
The convenience of a multi-port USB charger cannot be overstated. It allows you to power several gadgets from a single UK wall plug.
- USB-C Ports: This is the modern standard for fast charging. Look for chargers with at least one USB-C port that supports Power Delivery (PD), the protocol used by most new devices.
- USB-A Ports: While older, these ports are still useful for charging accessories like wireless headphones, smartwatches or older devices.
- Power Distribution: When using multiple ports simultaneously, the total wattage is distributed between them. A 100W charger might provide 65W to a laptop and 30W to a phone, for example. Check the product specifications to understand how power is shared.
3. Consider Size and Portability
One of the primary advantages of GaN technology is its compact size. If you travel frequently or want a minimalist setup, a compact travel charger is an excellent choice. Some models feature foldable prongs, making them even easier to pack away without scratching other items in your bag.
Our Top GaN Charger Picks
Based on features, power and portability, here are a few standout options available on Joybuy.
Baseus GaN5 Fast Charger (mini) 1C 30W
- Why It Stands Out: This charger is remarkably small for its power output. Using advanced GaN5 technology, it packs 30W of power into a body that fits easily in any pocket, making it a superb upgrade over the standard chargers included with most phones and tablets.
- Pros:
- Fast Charging: Delivers enough power to charge an iPhone 15 Pro to 50% in around 30 minutes.
- Extremely Compact: Its pocket-sized design makes it ideal for daily carry and travel.
- Broad Compatibility: Works with a wide range of USB-C devices, from smartphones to tablets and even the MacBook Air.
- Safety Features: Incorporates a 9-layer protection system to manage temperature and prevent over-voltage.
- Who is it for? Anyone looking for a powerful yet tiny replacement for their single-device charger. It's an excellent choice for smartphone users who prioritise portability.
Anker Prime, USB-C 3-Port GaN Charger, 100W
- Why It Stands Out: This is a true all-in-one charging station. With a massive 100W total output and three ports (two USB-C, one USB-A), it can handle a demanding workload, charging a high-performance laptop, phone and another accessory all at once.
- Pros:
- High Power Output: A single USB-C port can deliver up to 100W, enough to fast-charge a 14-inch MacBook Pro.
- Multi-Device Charging: The three ports provide flexibility for powering your entire tech arsenal.
- Travel-Ready: Despite its power, it remains compact and features foldable prongs for easy packing.
- Stable Design: Built with thicker prongs and a balanced structure to ensure it stays firmly in the wall socket.
- Who is it for? Professionals, students and frequent travellers who need a single charger for their laptop, phone and other gadgets. It’s a perfect solution for decluttering a desk or lightening a travel bag.
Anker Nano Pro USB-C Charger, 20W
- Why It Stands Out: The Anker Nano Pro is focused on doing one thing exceptionally well: fast-charging your phone in the smallest possible form factor. It is significantly smaller than Apple's 20W charger but delivers the same fast-charging performance.
- Pros:
- Optimised for Phones: The 20W output is ideal for fast-charging the iPhone 15 series and other modern smartphones.
- Incredibly Small: Its tiny size makes it almost unnoticeable in a bag or pocket.
- ActiveShield Safety: Features a temperature sensor and power tuner chip to protect your connected device.
- Stylish Finishes: Available in different colours to complement your device.
- Who is it for? Smartphone users who want the fastest possible charge in the most compact package. It’s a perfect, dedicated USB C fast charger for your primary mobile device.

Frequently Asked Questions about GaN Chargers
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 traditional silicon. This higher efficiency generates less heat, which allows manufacturers to build chargers that are much smaller and lighter without sacrificing power. For users, this means a more portable and powerful charging experience.
Can I use a 100W GaN charger for my phone?
Yes, you can. Modern smart charging technology, like USB Power Delivery (PD), allows the charger and your device to communicate. The charger will only supply the maximum amount of power that the device can safely handle. So, a 100W charger will safely fast-charge your phone without causing any damage.
Do I need a special cable for a GaN charger?
To get the full benefit of a fast charger, your cable matters. For charging a phone at 20-30W, most quality USB-C to USB-C or USB-C to Lightning cables will work. However, to deliver higher power, such as charging a laptop with a 100W laptop charger, you will need a USB-C cable that is specifically rated to handle 100W of power. Using an underrated cable will result in slower charging speeds.
