Design & Build Quality
The Anker Nano II 30W is one of the smallest high-output USB-C chargers available today. Its diminutive size, powered by GaN (gallium nitride) technology, makes it significantly smaller and lighter than traditional 30W chargers — roughly the size of an AirPods case.
✔ Compact & Travel-Friendly
At around 51 g, the Nano II 30W feels almost weightless in a pocket or backpack, making it ideal for commuters and travelers. Its foldable prongs (in some regional variants) add convenience and reduce bulk when packing.
✔ Durability & Materials
The charger uses a high-quality matte finish that resists fingerprints and scratches. The construction feels solid, and it doesn’t creak or flex under light pressure — an indication of good build quality.
✔ Port Layout
Since it’s a single-port charger, the USB-C port dominates the front face. This simplicity eliminates clutter while ensuring the cable fits snugly and securely.
In short, the design appeals to anyone who values portability without sacrificing power.
Charging Performance
The Anker Nano II 30W focuses on speed and efficiency for everyday devices.
30W Output Explained
With up to 30W power delivery, this charger is more than capable of fast-charging most modern phones. It delivers a significant boost over basic 5W/10W chargers and even performs faster than many stock chargers bundled with phones.
Real-World Charging Results
The exact charging speed will vary by device, but here’s what you can generally expect:
- Samsung Galaxy S24 / S23 series: ~50% in ~30–35 minutes
- Google Pixel 7 / Pixel 8: ~50% in ~30 minutes
- iPhone 14 / iPhone 15 series: ~50% in ~30–35 minutes
These results come when using a USB-C to USB-C or USB-C to Lightning PD-capable cable.
Single-Port Focus
Since the Nano II 30W has only one output, it’s optimized for speed to a single device at a time. That’s perfect for phones and tablets, but less ideal if you want to charge multiple devices simultaneously.
Charging Efficiency
Anker’s Nano series is remarkably efficient due to GaN technology, meaning less energy wasted as heat and more directed to your device.
Ports & Compatibility
The Anker Nano II 30W features a single USB-C port with USB Power Delivery (PD) support.
✔ USB-C Power Delivery (PD)
This ensures compatibility with a wide range of phones and tablets including:
- Samsung Galaxy S/A/Z Series
- Google Pixel
- iPhone (15 / 14 / 13 / exact PD support depends on Lightning cable)
- iPad Mini / iPad Air (PD charging)
- Nintendo Switch (in handheld mode)
- Other PD-enabled devices
No Multi-Device Support
Unlike multi-port chargers, this is meant for single-device fast charging, so you’ll need a second charger for other devices.
Heat & Efficiency
Thanks to GaN tech, the Nano II 30W stays cooler than traditional chargers:
- Warm but not hot during extended sessions
- Efficient power delivery with minimal energy loss
- Doesn’t throttle due to heat
This means you can safely use it for daily fast charging without worrying about overheating — even in warmer environments.
Safety Features
Anker builds its chargers with safety in mind. The Nano II 30W includes:
✔ Over-voltage protection
✔ Over-current protection
✔ Over-temperature protection
✔ Short-circuit protection
✔ CE / FCC / RoHS certifications
These safety layers help protect both the charger and your device from damage.
Real-Life Usage
Here’s how this charger works in real situations:
Travel Use
Ultra-compact size and foldable plug options make it perfect for frequent flyers. It hardly takes up space next to your laptop or other essentials.
Office or Home
Great for desktop charging when paired with a quality USB-C cable. The 30W output is enough for phones and smaller tablets.
Overnight Charging
Perfect for overnight or day-long charging, especially when you don’t need multi-port output.
Heavy Use
Can charge gaming devices like the Nintendo Switch or power bank inputs, though multi-port chargers may be better if you want to charge several devices at once.
