I Used the Anker Prime 240W GaN Charger for a Week | Review

If you’ve ever juggled between multiple chargers for your laptop, phone, tablet, and maybe even a smartwatch, all while still running out of power outlets, then the Anker Prime 240W GaN charger is made for you. It’s not just another fast charger. It’s a compact charging powerhouse designed to keep all your devices going with just one plug.

This charger brings together high-speed charging, next-gen GaN technology, and enough ports to make your entire setup simpler. Whether you’re a remote worker with a multi-device setup or someone who travels often and needs a single, reliable charger that does it all, this one checks a lot of boxes.

But does the Anker Prime 240W GaN charger actually deliver on its promise? Can it truly replace multiple bricks without slowing anything down? In this review, we’ll look at its design, charging speeds, heat management, and how it performs in everyday situations, from powering MacBooks and iPads to topping off your phone in record time.

Design and Build Quality

The first thing you’ll notice about the Anker Prime 240W GaN charger is how compact it is, especially considering the kind of power it delivers. It’s not as small as a basic phone charger, of course, but for something that can replace a laptop brick, it’s impressively slim and tidy.

It has a solid, matte finish with rounded edges, making it feel premium and rugged in hand. The body is built with heat-resistant materials that don’t just look good; they help the charger stay cool under pressure. The color scheme is Anker’s signature dark gray with subtle branding, giving it a professional, understated look.

On the front, you’ll find two USB-C ports and one USB-A port, neatly aligned. Just above them sits a small LED digital display, which shows you exactly how much power each device is drawing in real-time. It’s bright, clean, and easy to read, even in low light, which is surprisingly helpful when you want to know if your laptop is actually fast charging.

The foldable plug (for U.S. models) adds convenience for travel, while the overall weight, just under a pound, is balanced well for what it offers. It’s heavier than most small chargers, but still much lighter than carrying three separate ones.

The build feels durable, and the design gets out of your way. No flashy gimmicks, just clean functionality in a form factor that’s easy to trust and carry.

Ports and Output Configuration

What makes the Anker Prime 240W GaN charger such a standout is how intelligently it handles power across its three ports. You get two USB-C ports and one USB-A port, and the power distribution is smart enough to adjust based on what’s plugged in; no manual switching or toggling is needed.

The top USB-C port is the star here. It supports up to 140W output on its own, which is powerful enough to fast-charge large laptops like the 16-inch MacBook Pro. The second USB-C port goes up to 100W, which is still great for ultrabooks, tablets, and even power-hungry devices like the Steam Deck.

Then there’s the USB-A port, which supports up to 22.5W. This is more than enough for accessories like wireless earbuds, phones, or small peripherals. However, it’s not ideal for anything that needs high-speed USB-C charging. Still, it’s good to have when you need to charge older devices or a third gadget at once.

Here’s a simplified look at how the power is split:

• 1 device connected: You get the full power from one port (up to 140W)
• 2 devices connected: Power splits based on need, e.g., 140W + 100W
• 3 devices connected: The power is distributed intelligently (e.g., 140W + 65W + 22.5W max)

This dynamic power management is one of the charger’s biggest strengths. You don’t have to think twice; just plug and go. It figures out what each device needs and delivers it efficiently without overloading or slowing down the other ports.

Charging Performance

If there’s one area where the Anker Prime 240W GaN charger truly shines, it’s performance. This charger isn’t just about having multiple ports; it’s about delivering full-speed power to high-demand devices without compromise.

When using just one USB-C port, you can charge a 16-inch MacBook Pro at 140W, hitting Apple’s fast-charging threshold with ease. In testing, laptops charge from 0 to 50% in under 30 minutes, which is exactly what you’d expect from Apple’s original 140W charger, but here, you’re getting that and still having two ports to spare.

Plug in a second device, like a tablet or another laptop, and the charger redistributes power dynamically. For example, you could get 140W to your MacBook and still push 65–100W to a second device like an iPad Pro, Steam Deck, or Dell XPS. There’s no drop in quality, no noticeable slowdowns, and no overheating during multi-device charging.

The USB-A port, while limited to 22.5W, is perfect for phones, earbuds, and smaller accessories. It doesn’t support high-wattage charging like USB-C, but it’s great for topping off your third device without pulling power away from your main two.

Most importantly, the charger stays cool even under full load, thanks to the GaN tech and Anker’s built-in safety features. Charging remains consistent, and voltage delivery across all ports is stable.

Whether you’re powering a high-end workstation or charging your phone, tablet, and laptop all at once, this charger delivers reliable, top-tier performance.

Heat Management and Safety

With a charger this powerful, heat could easily become a problem, but that’s where GaN (Gallium Nitride) technology makes all the difference. The Anker Prime 240W GaN charger uses GaN tech to run more efficiently than traditional silicon-based chargers. That means less wasted energy and, more importantly, less heat.

Even when pushing out close to its full 240W capacity, the charger remains surprisingly cool to the touch. It gets warm, sure, but not worryingly hot. This is essential if you’re using it at your desk all day or traveling and charging multiple devices at once in tighter spaces.

Beyond just staying cool, the charger also packs a full suite of safety features:

• Active temperature monitoring: It constantly checks the internal temperature and adjusts power flow if things start heating up.
• Overload protection: If any device pulls more than it should, the charger automatically reduces or cuts off power to prevent damage.
• Short-circuit and surge protection: Essential for travel or fluctuating outlets, especially in airports or cafes.
• Dynamic power allocation: Prevents overheating by managing how much power goes to each port in real-time.

All of this works in the background, quietly protecting your gear while you stay focused. And unlike some high-wattage bricks that need cooling vents or fans, this charger does the job silently, another win for portability and peace of mind.

Compatibility and Use Cases

One of the best things about the Anker Prime 240W GaN charger is how versatile it is. It’s not just a laptop charger or a phone charger; it’s a universal solution that works across almost every modern device you can think of.

If you’re a MacBook Pro or Windows laptop user, this charger will likely replace your bulky original charger altogether. The top USB-C port supports up to 140W, which means full-speed charging for larger laptops, including 16-inch MacBooks and powerful ultrabooks that support USB-C PD 3.1.

For tablet users, especially iPad Pro or Galaxy Tab owners, the second USB-C port offers fast charging up to 100W, which is far more than you’ll need. It’s perfect if you’re editing on the go, gaming, or using the tablet as a second screen.

Smartphones and accessories also benefit here. The USB-A port might not have the wattage of USB-C, but it’s excellent for charging an iPhone, wireless earbuds, Apple Watch, or a Bluetooth speaker. If you’ve got a mix of devices from Apple to Android, from USB-C to USB-A, this charger won’t leave anything behind.

Some real-world use cases include:

• Travelers who want to pack one charger instead of three
• Remote workers with a multi-device setup at home or a co-working space
• Content creators are powering a camera, a laptop, and a phone at the same time
• Gamers on the go using Steam Decks, Nintendo Switch, or USB-C monitors

It’s truly a multi-role charger that works wherever and however you need it: at home, in a hotel, or during long hours at a cafe.

Smart Features and Display

Smart chargers usually stop at “fast charging,” but the Anker Prime 240W GaN charger adds something rare and genuinely useful: a built-in digital display. Right on the face of the charger, just above the ports, you get a clean, crisp readout of how much power each connected device is drawing in real-time.

This tiny screen might seem like a small addition, but it instantly makes you feel more in control. Instead of guessing whether your MacBook is charging at full speed or if your tablet is pulling less power, you can just glance at the numbers. It’s a great tool for tech enthusiasts, power users, or anyone who wants visibility into how their devices are performing.

The display automatically rotates through each port’s output (e.g., C1: 140W, C2: 65W, A: 15W), so even if you’re charging three devices, you’ll see how power is being shared. It updates in real-time and helps confirm whether your device is fast charging or just trickle charging.

While the charger doesn’t have built-in Bluetooth or Wi-Fi, it does work with Anker’s app, but only if you pair it with Anker’s optional charging base or station that supports app control. Most users won’t need this, but for those who want remote monitoring and usage stats, it’s a nice bonus feature in Anker’s ecosystem.

Portability and Daily Convenience

For something that pushes out a massive 240 watts, the Anker Prime 240W GaN charger is surprisingly compact, but it’s still not pocket-sized. This is more of a “carry it in your backpack” kind of charger than one you’d throw in your jacket pocket. That said, the size-to-power ratio is impressive, and it easily replaces three individual chargers.

Weighing just under 400 grams (around 0.9 lbs), it does add some weight to your tech bag, but if you’re used to lugging around a heavy laptop charger and a couple of phone/tablet adapters, this is actually an upgrade. With its foldable U.S. plug, it becomes even more travel-friendly. Just flip it in, pack it up, and go.

One small drawback: there’s no cable included in the box. You’ll need to bring your own USB-C to USB-C or USB-C to Lightning cables, depending on your devices. For a charger at this price point, an included high-wattage cable would’ve been a nice touch.

Another convenience feature is the charger’s ability to self-adjust wattage based on what you plug in. There’s no fiddling with switches or manual modes. Just plug in your gear, and it figures out what to do. That ease of use matters when you’re hopping between meetings, moving from office to home, or packing light for a trip.

For desk setups, the charger is compact enough to sit on the corner without cluttering your space. For travel, it’s a single item that simplifies your bag. In both cases, it does exactly what it’s supposed to do: make your life easier.

Price and Value

The Anker Prime 240W GaN charger is priced around $129.99, and while that might seem steep for a wall charger, it’s important to look beyond the number. This isn’t just another USB-C adapter; it’s a full replacement for your laptop charger, tablet charger, phone charger, and even your power strip, all in one.

Think about it this way: Apple’s 140W charger for the MacBook Pro alone costs about $99 and only charges one device. Add a fast phone charger and a tablet charger to that, and you’re easily spending more than Anker’s price without gaining the portability or compactness this charger offers.

The real value of the Anker Prime 240W GaN charger lies in what it replaces and how reliably it performs. You’re not just paying for high wattage; you’re paying for build quality, safety, smart power distribution, and the convenience of carrying one well-designed device instead of three separate bricks.

For professionals, frequent travelers, and anyone with a multi-device setup, it makes sense. You save space, reduce clutter, and charge everything faster without worrying about compatibility or heat issues. For casual users with only one or two small devices, it might be overkill, but for power users, it’s an investment that simplifies everyday charging.
