USB-C Charger Buying Guide: Choose the Right Charger for Your Devices

USB-C has established itself as the universal standard for our electronic devices, from smartphones to laptops. However, choosing the right USB-C charger can quickly become a headache: wattage, compatibility, GaN or Power Delivery technology... It's easy to get lost.

As high-tech experts, our mission at Joybuy is to demystify the topic for you. This guide gives you all the keys to finding the perfect USB-C power adapter for your needs, whether you're replacing a lost charger, upgrading to faster speeds, or simply want to travel lighter.

How to Choose the Right USB-C Charger

Before diving into our top picks, let's review the essential criteria to ensure you make the right choice.

1. Power (in Watts): The Most Critical Factor

Power, measured in watts (W), is the number one criterion: it dictates the charging speed. An underpowered charger will take forever to recharge a power-hungry device.

• For smartphones (iPhone, Samsung Galaxy, etc.): A 20W to 30W charger is more than enough for fast charging.
• For tablets and ultraportables (iPad, MacBook Air, etc.): Aim for a power output of 45W to 67W for efficient recharging.
• For the most powerful laptops (MacBook Pro, etc.): A MacBook charger of 96W, 100W, or more is often required to charge the machine while it's in use.

The rule of thumb: always check the maximum power your device can handle to make the right choice.

2. Technology: GaN and Power Delivery (PD)

These two acronyms are everywhere, and for good reason.

• GaN Charger: Gallium nitride (GaN) is a semiconductor that is replacing the traditional silicon in chargers. The result: a GaN charger is smaller, lighter, and runs cooler than a conventional charger of the same wattage. A decisive advantage for nomads and minimalists.
• Power Delivery (PD) Charger: This is the universal fast-charging standard that works via USB-C. It allows the charger and the device to "talk" to each other to intelligently adjust the power delivered. A Power Delivery charger guarantees a charge that is not only fast but also perfectly safe.

3. The Number of Ports: One to Rule Them All

If you travel often or simply want to declutter your desk, a multi-port USB-C charger is the ideal solution. These models allow you to simultaneously charge a laptop, a smartphone, and a tablet with a single power brick. Be aware, however, that the total power is shared among the ports. A 67W charger, for example, will not deliver 67W to each port at the same time.

Top USB-C Charger Picks

To move from theory to practice, here is our selection of three models that cater to very different user profiles.

UGREEN X512 20W GaN 1x USB-C Wall Charger - White

Why It Stands Out

This UGREEN charger is the epitome of efficiency in an ultra-compact form factor. Thanks to GaN technology, it delivers 20W in a tiny housing, barely larger than Apple's old 5W charger.

Advantages

• 20W Power Output: Perfect for fast-charging the latest iPhones and most Android smartphones.
• GaN Technology: Extremely compact and lightweight, it slips into any pocket.
• Wide Compatibility: It supports PD 3.0 and QC 3.0/4.0 protocols, ensuring compatibility with a vast range of devices.
• Built-in Safety: It includes essential protections against over-voltage, over-current, and short circuits.

Who Is It For?

This is the smart choice for anyone looking for a dedicated iPhone charger or smartphone charger that is both powerful and ultra-portable. Ideal as a primary phone charger or as a daily backup.

Anker Prime 67W GaN USB C Fast Charger

Why It Stands Out

The Anker Prime 67W is a true Swiss Army knife. With its two USB-C ports and one USB-A port, it can power up to three devices at once. Its compact design and foldable plug make it an ideal travel companion.

Advantages

• 3-in-1 Charging: Two USB-C ports and one USB-A port to simultaneously charge a laptop, a smartphone, and earbuds.
• 67W Power Output: Enough to power a MacBook Air or a 13-inch MacBook Pro at full speed (when using a single port).
• Ultra-Compact and Foldable: According to Anker, it's 51% smaller than the original 67W MacBook charger, and its foldable prongs make it perfect for transport.
• ActiveShield 2.0 Technology: An active temperature monitoring system that ensures a completely safe charge.

Who Is It For?

This multi-port USB-C charger is aimed at mobile professionals, students, and anyone who wants to replace their arsenal of chargers with a single power brick. The ultimate all-in-one solution for the office, home, or travel.

Apple 140W USB-C Power Adapter

Why It Stands Out

Apple's official power adapter is a powerhouse, tailor-made for the brand's most demanding devices. Its 140W output allows you to unlock the full ultra-fast charging potential of the latest MacBook Pro models.

Advantages

• 140W Power Output: Enables blazing-fast charging. Apple states it can charge a 16-inch MacBook Pro (2021 and later) to 50% in about 30 minutes (with a compatible cable).
• Optimised Apple Compatibility: Designed for seamless integration within the Apple ecosystem, from iPhone to MacBook.
• Build Quality: As an official product, it benefits from the high quality and safety standards of the Apple brand.

Who Is It For?

This charger is primarily for owners of the 16-inch MacBook Pro (or other high-performance laptops) who demand maximum charging power to cut their waiting time to the bare minimum. Note: the charging cable is sold separately.

Frequently Asked Questions About USB-C Chargers

Can I use a USB-C charger that is more powerful than my device requires?

Yes, absolutely. Thanks to protocols like Power Delivery (PD), the charger and the device communicate with each other. The device will only "draw" the power it needs, and never more. Using a 67W charger for a smartphone that only requires 20W is therefore completely safe.

Is a GaN charger necessarily more powerful?

Not necessarily. GaN technology doesn't increase power, but it radically improves energy efficiency. For the same wattage, a GaN charger will be more compact, lighter, and generate less heat than a conventional silicon-based charger.

What is the difference between the USB-C port and Power Delivery (PD)?

USB-C is the name of the physical connector—that small, oval, reversible plug that you can connect without ever getting the orientation wrong. Power Delivery (PD), on the other hand, is the smart charging technology that travels through this connector. It's PD that enables fast charging and secure communication between the charger and your device.
