If you have ever travelled with a bag full of separate bricks, one for the laptop, one for the phone, one for the tablet, you already know the problem a good GaN charger solves. The old silicon wall chargers that ship with most devices are bulky, slow, and single-purpose. A modern GaN charger does the opposite. It packs more power into a smaller shell and charges a laptop and a phone at the same time from a single wall socket. For anyone in Singapore juggling a MacBook, an iPhone or Android phone, and a pair of earbuds, that shift matters.
The tricky part is choosing the right wattage. A 65W GaN charger is perfect for a phone and a thin-and-light laptop, but it will struggle to keep a 16-inch MacBook Pro topped up under heavy load. Step up to 100W, 140W, or 200W and you can run a full laptop plus several accessories without thinking about it. This guide walks through the best GaN chargers in Singapore across the full range, covering GaN7 technology, USB-C Power Delivery, multi-port charging, and worldwide travel pins.
Founded in 2009, Mazer is a Singapore-based brand trusted by over 500,000 customers, with 1.5M+ units sold worldwide. Every charger in this guide is backed by a 24-month warranty and built with Mazer's InfiniteShield safety protection, so you get fast charging without gambling on your devices. If you want the wider picture first, read more about what a GaN charger actually is before you pick a wattage tier.
What to Look for When Choosing a GaN Charger in Singapore
Picking a GaN charger is less about brand names and more about matching output to your devices. A charger that is too weak will charge slowly, and one that is far too powerful is money spent on headroom you may never use. Before you buy, run through the points below so the GaN charger you choose fits your laptop, your phone, and the way you travel.
- Total wattage: Choose 65W for a phone and light laptop, 100W to 140W for a full laptop plus accessories, and 200W for heavy multi-device charging.
- Number of ports: More USB-C and USB-A ports let you charge a laptop, phone, and earbuds together from one socket.
- Per-port output: Check the single-port figure, since a 140W charger may only deliver full wattage when one port is used.
- USB-C Power Delivery: Look for PD 3.0 or PD 3.1 support so laptops and phones negotiate the fastest safe charging speed.
- GaN7 technology: The latest GaN chipset runs cooler and smaller than older silicon, which means less heat and a more compact brick.
- Travel pins: Interchangeable UK, EU, and AU pins with 100-240V input make one charger work across every trip.
- Safety protection: Over-current, over-voltage, overheating, and short-circuit protection guard your devices during fast charging.
- Smart display: An AI display shows real-time wattage per port, which is useful for confirming your laptop is pulling full speed.
- Warranty and local support: A local Singapore warranty means easier claims than a grey-market marketplace unit.
Once you know your total wattage and how many devices you charge at once, the shortlist gets short fast. The picks below are grouped by power tier so you can jump straight to the one that fits, all available through the official Mazer chargers collection.

Frequently Asked Questions about GaN Chargers
This FAQ answers the most common questions Singapore buyers ask about GaN chargers, covering wattage, compatibility, safety, and how to pick between the different power tiers.
1. What is a GaN charger?
A GaN charger uses gallium nitride semiconductors instead of the silicon found in traditional chargers. This allows the charger to be smaller, run cooler, and deliver more power efficiently, which is why a modern GaN charger can fast-charge a laptop and a phone from one compact brick.
2. Is GaN better than a normal silicon charger?
Yes, for most people. GaN chargers are more power-dense, so they pack higher wattage into a smaller size while producing less heat and offering higher efficiency. That means faster multi-device charging without the bulk of an older silicon brick.
3. What wattage GaN charger do I need for a laptop?
A 65W to 100W GaN charger suits thin-and-light laptops like a MacBook Air or an ultrabook. For a 16-inch MacBook Pro or a gaming laptop under load, a 140W or 200W charger gives you the headroom to charge at full speed while running other devices.
4. Can a 100W GaN charger charge a MacBook Pro?
A 100W GaN charger will charge most MacBook Pro models, and for a 14-inch model it is usually plenty. For the 16-inch MacBook Pro at maximum fast-charge speed, a 140W charger such as the GaNPrestige 140W or AiPrestigeGaN 140W is the better match.
5. Can GaN chargers charge phones and laptops at the same time?
Yes. The multi-port Mazer GaN chargers in this guide are designed to charge a laptop, phone, and accessories together. Keep in mind that total output is shared, so a 140W charger might deliver 100W to a laptop and split the rest across the other ports.
6. Are GaN chargers safe to use?
GaN chargers from reputable brands include multiple safety protections. Every Mazer GaN charger here uses InfiniteShield protection against over-current, over-voltage, overheating, and short-circuits, and the AiPrestigeGaN adds Infinite Shield 7.0 with 24-hour active safety monitoring.
7. Do these GaN chargers work overseas?
Yes. All of these Mazer chargers accept worldwide 100-240V input, and the 140W and 200W models include interchangeable UK, EU, and AU travel pins. That makes a single GaN charger suitable for trips across the region and beyond.
8. What does GaN7 technology mean?
GaN7 refers to Mazer's latest generation of gallium nitride chipset, used in the AiPrestigeGaN range. It delivers higher efficiency with less heat in an even more compact size compared to earlier GaN designs, which supports safer and smarter fast charging.
9. How many ports should my GaN charger have?
It depends on how many devices you charge at once. Two ports suit a laptop and a phone, three ports add room for earbuds or a tablet, and four ports on the 140W and 200W models are ideal for a busy desk or a family that charges several devices together.
10. Where can I buy a GaN charger in Singapore?
You can buy Mazer GaN chargers online through the official Mazer store at whymazer.com, with nationwide delivery across Singapore and a 24-month local warranty. Browse the full range in the Mazer chargers collection to compare wattage tiers side by side.
