How to Choose the Right USB-C Fast Charger

By the Joybuy Editorial Team, July 5, 2026

The charger has disappeared from the box of our smartphones, tablets, and laptops. This trend, started by a few, has now been adopted by nearly every manufacturer. The result: between the underpowered old adapters lying in our drawers and the empty space in the box, many of us are on the hunt for the ideal charger. But the market is a jungle of acronyms—USB-C PD, GaN, PPS—making it easy to get lost.

Our mission today is to help you decode this jargon and choose the model that’s truly right for you, without getting bogged down in marketing hype. Follow our guide to find the power adapter that will re-energise your devices, quickly and efficiently.

How to Choose the Right USB-C Fast Charger?

Before you grab the first model you see, let's review the key criteria that make all the difference.

1. Power (in Watts): Aim for What's Right, Not Just What's Highest

Power, measured in watts (W), is the crucial factor. A 45W charger or a 65W charger will deliver charging speeds that are worlds apart from an old 5W or 10W adapter.

• For a smartphone: Most recent models (iPhone, Samsung Galaxy, Google Pixel) max out at a power between 25W and 45W to reach their top charging speed. A 45W charger is therefore an excellent, versatile, and future-proof choice.
• For multiple devices or a laptop: If you plan to charge your phone and a tablet simultaneously, or power a USB-C compatible laptop (like a MacBook Air), a 65W model (or higher) is a must. And don't worry, there's no risk of damage: your device will only "draw" the power it needs.

2. GaN Technology: The Secret to Compact and Efficient Chargers

The acronym GaN stands for gallium nitride. A GaN charger uses this advanced semiconductor instead of traditional silicon. The advantages are immediate:

• Extreme Compactness: GaN chargers are significantly smaller and lighter.
• Controlled Heat: They convert energy more efficiently, which reduces heat loss during charging.

This technology is a key advantage for a travel charger, where every gram and square centimetre counts.

3. Ports and Protocols: The Key to Flawless Compatibility

The number and type of ports determine the charger's versatility. A dual USB-C charger allows you to charge two devices at the same time by intelligently distributing the power.

But ports aren't everything; charging protocols are just as crucial. The USB Power Delivery (PD) standard has become the near-universal norm, ensuring fast charging for most devices, including being the basis for an iPhone fast charger. For certain Android devices, especially Samsung's flagships, the PPS (Programmable Power Supply) protocol is a significant advantage. It dynamically adjusts voltage and current to optimise charging speed while preserving battery health. For Galaxy owners, a Samsung 45W charger that is also a PPS charger is therefore the logical choice.

Frequently Asked Questions (FAQ)

1. Can I use a 65W charger on a smartphone that only accepts 25W? Yes, absolutely. Modern chargers communicate with devices to negotiate the optimal charging power. The charger will only supply the maximum power that the smartphone can safely accept. Using an overpowered charger therefore poses no risk to your battery.

2. Is GaN technology essential? No, not essential, but highly recommended, especially for power outputs above 30W. A GaN charger will be smaller, lighter, and run cooler than a non-GaN charger of the same wattage. The improvement in comfort and portability is undeniable, particularly when travelling.

3. Is a USB-C fast charger compatible with an iPhone? Yes. Since the iPhone 8, all models have been compatible with fast charging via the USB-C Power Delivery (PD) protocol. For models released before the iPhone 15, you will need a USB-C to Lightning cable. Starting with the iPhone 15 series, a simple USB-C to USB-C cable does the job. In short, an iPhone fast charger is simply a USB-C PD charger of at least 20W.
