AI Verdict
A 47W GaN charger with two USB-C ports (27W/20W split) for simultaneous phone and tablet charging.
This charger is a strong fit for users who need to power two USB-C devices like a phone and tablet simultaneously, or a single laptop like a MacBook Air, while traveling. Its 47W total output and compact, foldable design directly address these common use cases.
If you need higher individual port wattage for two laptops, look for a charger with 60W+ per port or a higher total wattage like 65W or 100W.

Pros
- Provides 47W total power output, with a 27W port and a 20W port for simultaneous device charging.
- Features foldable prongs, making it compact for travel and preventing snagging in bags.
- Utilizes GaN technology, allowing for a smaller physical size compared to older silicon-based chargers.
- Includes ActiveShield 2.0 technology, monitoring temperature over 3 million times daily for device protection.
- Can deliver up to 45W from a single USB-C port for charging a MacBook Air or other USB-C notebooks.
- Its compact footprint avoids blocking adjacent outlets on power strips or wall sockets.
Cons
- The 47W total output is split between the two ports (27W and 20W), not available at full wattage for each port simultaneously.
- Charging cables are not included in the package.
- Lacks a USB-A port, limiting compatibility with older devices requiring that connector type.
- Some users might find the 'Nano' branding misleading if expecting extreme miniaturization beyond its 'original 20W charger' size comparison.
Dimension Scores
Provides up to 45W for a single device like a MacBook Air and a 27W/20W split for dual phone/tablet charging, which is fast for its category.
Anker is known for durable products, and the inclusion of ActiveShield 2.0 for temperature monitoring indicates robust internal design.
Works with a wide range of USB-C devices including iPhones, Galaxies, Pixels, iPads, and MacBook Airs.
Its compact size, similar to a 20W charger, and foldable prongs make it highly portable and travel-friendly.
Best For
- Travelers needing to charge an iPhone and iPad simultaneously with minimal bulk.
- Students powering a MacBook Air and a smartphone from a single wall outlet.
- Users with multiple USB-C devices who prioritize compact size over maximum individual port wattage.
- Anyone replacing an older, larger 20W charger with a more powerful, dual-port alternative.
Not Recommended For
- Power users needing 40W+ from both USB-C ports simultaneously for two high-demand devices.
- Individuals who only own USB-A charging cables and prefer not to purchase new USB-C cables.
- Users requiring a charger with an integrated power switch for control over power flow.
Watch Out For
- The 47W advertised power is a shared total; plugging in two devices splits the power to 27W and 20W, not 47W per port.
- You'll need to supply your own USB-C charging cables, as none are included in the box.
- While compact, it's roughly the size of an original 20W charger, so don't expect something drastically smaller than that benchmark.
- Some users report the charger can get warm when both ports are under heavy load, though ActiveShield 2.0 manages temperature.

What Buyers Say
Many users initially expect 47W from each port, but the charger actually splits its total 47W output into 27W and 20W when two devices are connected. People consistently praise its compact form factor and foldable prongs, making it a favorite for travel. The ability to charge an iPhone and an iPad simultaneously, or a MacBook Air alone, is a frequently mentioned benefit. While the lack of an included cable is a common observation, it doesn't deter most buyers due to the charger's overall convenience and performance.
“Ugh, another charger without a cable, seriously? But fine, it's tiny and charges my iPhone and iPad at the same time, so I guess I'll keep it for my travel bag. Just wish both ports were full power.”
Common Praise
- The foldable prongs are a game-changer for travel, preventing snags and making it easy to pack.
- Charges an iPhone and an iPad at the same time, which is super convenient for daily use.
- It's surprisingly small, fitting easily into pockets or small compartments without taking up much space.
- Doesn't block other outlets on a power strip, which is a huge plus.
- Fast charges my MacBook Air when I only have one device plugged in.
- Automatically adjusts power for different devices, so I don't have to worry about overcharging my earbuds.
Common Complaints
- Really wish it came with at least one USB-C cable; having to buy one separately is annoying.
- The 47W is shared, so I can't fast charge my laptop and another high-power device at the same time.
- It gets noticeably warm when I'm charging both my phone and tablet, especially if they're both low.
- The 'Nano' name feels a bit like marketing; it's small, but not microscopic.
Ownership Tips
- After a few weeks, I noticed it consistently gets warm, not hot, when charging two devices, but ActiveShield 2.0 seems to prevent any issues.
- The foldable prongs haven't loosened up at all, still snap firmly into place even after months of use.
- It's become my go-to travel charger because it replaces two separate bricks and fits anywhere.
- I've found that if I need to quickly charge my laptop, I just unplug my phone to get the full 45W, then plug the phone back in later.
Frequently Asked Questions
Does this charger come with any charging cables?
No, the Anker Nano 47W charger does not include any charging cables; you will need to use your own USB-C cables.
Can both USB-C ports output 47W at the same time?
No, the 47W is the total combined output. When two devices are connected, the power is distributed as 27W from one port and 20W from the other.
Is this charger compatible with my MacBook Air?
Yes, either USB-C port can provide up to 45W of power, which is sufficient to fast charge a MacBook Air.
What is ActiveShield 2.0?
ActiveShield 2.0 is Anker's proprietary safety technology that monitors the charger's temperature over 3 million times per day to prevent overheating and protect your devices.
Will this charger work with my older iPhone model?
Yes, if you have a USB-C to Lightning cable, this charger will fast charge older iPhone models that support USB-C Power Delivery, automatically adjusting the power output.
How compact is this charger for travel?
It's roughly the same size as an original 20W charger and features foldable prongs, making it very convenient for travel and easy to pack.
Buying Guide
When you're looking at chargers, especially compact ones, the total wattage is important, but how that power is distributed across multiple ports is crucial. This Anker Nano 47W charger gives you two USB-C ports, but the 47W is a total. If you plug in two devices, it splits to 27W and 20W. This is fine for phones and tablets, or a single laptop, but don't expect two high-power devices to charge at their maximum speed simultaneously. Also, always check if cables are included, as many compact chargers skip them to keep costs down.
Watts (47W)
This number tells you the maximum total power the charger can deliver. Think of it like the horsepower of a car; higher watts mean faster charging, but only if your device can handle it. For this charger, 47W is enough to fast charge most phones, tablets, and even some smaller laptops like a MacBook Air.
USB-C Ports (2)
This indicates the type and number of outlets available. USB-C is the modern standard, used by most new phones, tablets, and laptops. Having two means you can charge two compatible devices at once, like your phone and your headphones, or your tablet and your smartwatch.
GaN Charger
GaN (Gallium Nitride) is a newer material used instead of silicon in chargers. It allows chargers to be much smaller, more efficient, and run cooler than older chargers with the same power output. This is why this 47W charger can be roughly the size of an older 20W one.
Foldable Prongs
This is a small but significant feature for portability. The prongs fold flat into the charger's body, preventing them from scratching other items in your bag or breaking off during travel. It makes the charger much more pocket-friendly.
Alternatives
If you need more power per port for multiple laptops, look for chargers with 60W+ per USB-C port. If you still use older devices, search for chargers that include at least one USB-A port alongside USB-C.
