Product Overview
The Anker Nano Charger (70W, 3 Ports) delivers powerful, fast charging in a compact, travel-friendly design. Built for users who need to charge multiple devices simultaneously—from laptops to smartphones—this charger combines high output with thoughtful engineering. With three ports (two USB-C and one USB-A), it supports a wide range of devices including MacBooks, iPhones, iPads, Galaxy phones, and Pixel devices. Its small size doesn’t sacrifice performance, making it ideal for home, office, or on-the-go use. The included USB-C cable adds convenience right out of the box.
Key Features
- 70W Max Output via Single USB-C Port – Delivers up to 70W from either USB-C port, enabling rapid charging for power-hungry devices like the MacBook Air and Pro. Dual GaN (Gallium Nitride) chips ensure efficient power delivery, reduce heat, and allow for a smaller, lighter build without compromising speed.
- Three-Port Versatility – Charge up to three devices at once. The USB-C1 and USB-C2 ports each support up to 70W individually, while the USB-A port provides up to 33W. Intelligent power distribution adjusts output based on connected devices—ideal for topping up a laptop, phone, and earbuds simultaneously.
- Compact and Stable Design – Engineered to stay upright in wall outlets thanks to a balanced internal layout and low-profile construction. The widened spacing between ports reduces cable crowding by up to 81% compared to standard chargers, making it easier to plug in multiple cables without interference.
- Advanced Thermal Management – Operates up to 50°F (10°C) cooler than international safety standards during high-load charging. This helps protect your devices from overheating and extends the charger’s lifespan under heavy use.
- Color Options to Match Your Style – Available in black, white, green, and pink, allowing users to choose a charger that complements their workspace or personal aesthetic without sacrificing performance.
- Included USB-C Cable – Comes with a USB-C cable for immediate use, eliminating the need for an additional purchase.

Important Notes
- Performance may vary based on usage conditions such as ambient temperature, device battery level, and active applications. Maximum 70W output is typically achieved when the device battery is low and the screen is off.
- For low-current devices like electric shavers or hearing aids, use the USB-A port alone for improved charging reliability.
- When charging a MacBook with a third-party charger, a plug icon may appear briefly before switching to a lightning bolt—this is normal and charging continues unaffected.
- A “slow charging” notification on laptops may appear if the device’s power requirement exceeds the 70W maximum from the USB-C1 port. Check your laptop’s original charger rating for compatibility.
- This charger does not support 60W Super Fast Charging 3.0.
- Size and weight comparisons are based on internal testing against standard 70W USB-C chargers. Actual weight may vary slightly.
