We’ve all been there. You’re rushing out the door, juggling your phone, laptop, and maybe a tablet, only to realise each one needs its own bulky power brick. Your bag feels heavier than it should, and your desk is a tangled mess of cables. Worse yet is plugging in your phone for a quick 30-minute charge before you leave, only to see the battery barely budge.
In a world of powerful, power-hungry devices, the standard chargers we get often feel like they’re stuck in the past. The clutter is real, and slow charging is a genuine frustration.
But what if you could replace that entire collection of charging bricks with a single, tiny, ultra-fast adapter? That’s the promise of the Anker 313 PowerPort 45W, a compact charger powered by advanced GaN technology. In this in-depth review, we'll find out if this is the ultimate all-in-one charging solution for the savvy Singaporean.
What is GaN Technology and Why Should You Care?
You’ve probably seen "GaN" pop up on tech websites, but what does it actually mean for you? In simple terms, Gallium Nitride (GaN) is a modern semiconductor material that is far more efficient than the traditional silicon used in most chargers. This breakthrough allows manufacturers to build chargers that are significantly smaller, run cooler, and waste less energy, all while delivering more power.
Smaller Size, Bigger Power: The Portability Advantage
The most immediate benefit of GaN is size. The Anker 313 can push out 45W of power—enough for a MacBook Air—from a body that’s barely larger than an old 5W iPhone cube. It’s small enough to slip into any pocket or the most crowded compartment of your bag, making it a game-changer for portability.
| Charger Comparison | Approximate Size (cm) | Power Output |
| Standard 45W Laptop Charger | ~7.5 x 7.5 x 3.0 | 45W |
| Anker 313 (45W) GaN | 3.8 x 3.5 x 4.1 | 45W |
| Standard 5W Phone Charger | ~2.8 x 2.8 x 3.0 | 5W |
Cooler and Safer Charging
Because GaN components are more efficient, they generate significantly less waste heat. This means the charger stays cooler to the touch even during a fast-charging session, which is not only safer but also better for the longevity of the charger and your device's battery.
Better for Your Wallet and the Planet
Higher efficiency means less electricity is wasted as heat during charging. While it might not drastically slash your SP bill overnight, using more efficient electronics is a small step towards being more eco-friendly and, over time, contributes to energy savings.
Deep Dive: Anker 313 (45W) Charger Key Features
Straight out of the box, the Anker 313 feels solid and premium. Weighing a mere 90g with a minimalist design and foldable prongs, it’s clearly built for life on the move. But the real magic is inside.
45W High-Speed Charging: Powering Everything You Own
At the heart of this charger is Anker’s PowerIQ 3.0 technology, which intelligently communicates with your connected device to deliver the fastest possible, optimized charge. This isn't just a phone charger; its 45W output is powerful enough to handle a wide range of gadgets, from your iPhone and Samsung Galaxy to your iPad Pro and even your MacBook Air.
To put its speed into perspective, here's how it stacks up against a standard charger.
| Device (from 0%) | Charge Time with Standard 5W Charger | Charge Time with Anker 313 (45W) |
| iPhone 15 to 50% | ~90 minutes | ~28 minutes |
| Samsung S24 Ultra to 50% | ~75 minutes (at 15W) | ~20 minutes |
Samsung Super Fast Charging 2.0 Ready
If you own a flagship Samsung phone, this feature is critical. The Anker 313 supports Programmable Power Supply (PPS), a charging standard required for Samsung’s “Super Fast Charging 2.0.” This allows it to deliver the full 45W, making it a top-tier fast charger for Samsung S23 and S24 users.
As local tech enthusiast Marcus Chan notes, "Many 45W chargers on the market lack PPS, meaning they can't actually 'super fast charge' a Samsung phone at maximum speed. The Anker 313 is one of the most compact and reliable options that gets it right."
Advanced Safety with ActiveShield™
We’ve all had that unsettling experience with a cheap, third-party charger that gets alarmingly hot. It’s a real worry, given how expensive our devices are. Anker addresses this with its ActiveShield™ safety system. A Dynamic Temperature Sensor constantly monitors heat levels, while a Power Tuner Chip adjusts the output to protect your device. This provides peace of mind that your gadgets are charging not just quickly, but safely.
Real-World Use Case: Is This the Perfect Charger for Singapore?
The Daily Commuter: Tossing this tiny charger into your work bag is a no-brainer. It takes up virtually no space and ensures you can top up your laptop and phone between meetings or on the MRT without carrying heavy bricks.
The Hybrid Worker: One day you’re at your home office, the next you’re at a café in Katong. The Anker 313 simplifies your setup. It's the one charger you need for your phone, tablet, and USB-C laptop charger needs, decluttering your workspace wherever you are.
The Avid Traveller: With its foldable prongs and universal 100-240V input, this is the ultimate compact travel adapter. Whether you’re heading to KL for the weekend or flying to Europe, this is the only charging block you’ll need to pack.
