The Perfect Everyday Charger!
Anker has a reputation for making some of the best charging gear out there, and the Nano 47W absolutely lives up to it. It’s the rare kind of product that gets everything right — performance, design, and reliability — all in one tiny package.The dual USB-C ports are incredibly convenient. I can charge my phone and iPad (or laptop) at the same time without sacrificing speed. The 47W output is plenty for most devices — it fast-charges my iPhone and iPad Pro simultaneously, or my MacBook Air solo, with no heat or slowdown. The intelligent power distribution is seamless; it automatically adjusts output depending on what’s plugged in.What I really appreciate is the form factor. It’s about the size of a single-port charger, yet somehow delivers nearly 50 watts of power. The foldable prongs make it ultra travel-friendly, and the matte finish gives it a premium, durable feel.After several weeks of daily use — plugged, unplugged, tossed in a bag — it still looks brand new and performs flawlessly. No coil whine, no heat buildup, no cheap plastic smell. Just pure, dependable performance every time.If you’re tired of carrying multiple bulky chargers, this is the perfect all-in-one solution. Anker continues to prove why they’re the gold standard for charging accessories.Highly recommended — small in size, big in performance, and worth every penny.

Anker’s Best: The Dual USB-C Powerhouse
Switching to this specific Anker charging plug was a game-changer for my entire mobile workflow. Anker has truly perfected the balance between power, portability, and dependability, making this the single essential charging tool for all my devices, especially with its intelligent port configuration.The standout feature is the convenience of the two dedicated USB-C ports. This is exactly what modern users need. I can now simultaneously charge my phone and my tablet—or even my phone and a small laptop—all from one compact outlet. It eliminates the need for multiple plugs, dramatically cutting down on clutter both at home and in my travel bag.Beyond the convenience, the high-speed charging performance is phenomenal. Utilizing advanced power delivery, this block intelligently splits or combines its wattage to ensure every device gets the fastest, safest charge possible. Charging times are drastically reduced across the board. Whether I’m powering up quickly before a meeting or topping off both devices overnight, the reliability of this rapid charging capability is unmatched.Despite this dual high-power capability, the block remains surprisingly compact and travel-friendly. The build quality is excellent, as expected from Anker: solid, durable, and reliable. If you’re looking to streamline your charging setup with a fast, versatile, and dependable dual USB-C solution, look no further. This Anker plug is simply the best in class.

Good product. Don’t hesitate, buy it.
It might charge my phone and iPad but a problem occurs when charging the iPad, my iPad will not open. It only opens after charging is complete and disconnected from the Anker charger. This doesn’t happen when charging with an Apple charging block. Since I spend most of my day on the iPad, this is infuriating.Update: 10-3-25, I want to retract the above review. The outlet that the charger was plugged into is the problem. After using the Anker charger in a different wall outlet, the charger is working. Apologies. And thank you for contacting me regarding the problem.

Good option for traveling if you need more than 1 port.
The 45w single port is a lot smaller and lighter. I’d recommend that unless 2 ports is a necessity. If weight isn’t an issue, you can get a 67w and 70w at roughly the same size as this 47w 2 port charger.The 47w 2 port is roughly the same size as the 67w Anker Prime 3 port GaN charger, but a lot lighter. The Anker Nano 70w 3 port is slightly shorter but longer. The 70w fits better in a crowded power bar but the 47w 2 port tends to work better when traveling since it’s lighter. Both are powerful enough to quick charge my phone and charge up my laptop (Mac Book).

I purchased this charger specifically for use with my new iPhone 17 Pro, based on Apple’s claim that a 40W charger could deliver a 50% charge in just 20 minutes. Initially, my experience was underwhelming. During the first two weeks, I was unable to achieve the advertised performance, despite testing multiple USB-C cables rated at 60W, 100W, and even Apple’s own 60W cable included with the device.In most cases, the charging wattage hovered between 20–25W, with brief spikes above 30W. After conducting extensive tests, I discovered that charging wattage is highly dependent on the battery’s current level — the higher the battery percentage, the lower the charging rate.To test this further, I drained my iPhone to 3% and began charging from that point. The results were impressive: the charger consistently delivered 32–34W between 3% and 32%, and the phone reached 51% in exactly 20 minutes. At peak performance, the charger’s temperature was approximately 40°C, though it remained comfortably lukewarm to the touch.When charging 2 devices at the same time, it does give each port around 20W of charging.Based on these findings, I can confidently recommend this charger for users seeking fast and reliable charging — especially when starting from a low battery level.
