Anker Nano Power Bank Review: The Pocket-Sized Powerhouse

Anker Nano Power Bank



Portable charging solutions are no longer just a ‘nice-to-have’; they are pretty much a necessity in today’s digital age. Whether you’re a busy professional or a constant traveller, keeping your devices juiced up is imperative. This is where Anker Nano Power Bank comes into play. With its 22.5W high-speed charging, foldable USB-C connector, and a form factor designed for ultimate portability, it promises to be an all-rounder. So, how well does it deliver on its promises? Let’s dive in.

Design: A Focus on Portability and Responsibility

Right off the bat, the power bank exudes an aesthetic blend of style and utility. Its compact design makes it a perfect fit for pockets and purses alike. More impressively, Anker has taken a responsible approach by crafting the exterior from 75% post-consumer recycled (PCR) materials. This not only minimizes the environmental impact but also appeals to the eco-conscious consumer.

However, the foldable USB-C connector steals the show. It cleverly eliminates cable tangling issues and also protects the connector when not in use. The design, while compact, is sophisticated enough to accommodate phone cases up to 4.9mm thick.

Features: Advanced Charging and Safety Measures

Equipped with dual USB-C ports and PowerIQ 3.0 technology, this little beast outputs an impressive 22.5W, ensuring high-speed charging for your devices. While the device includes a USB-C to USB-C cable, it also supports a USB-C to Lightning Cable (sold separately), broadening its compatibility range to cover a wide array of Apple devices.

What sets this power bank apart is its ActiveShield™ 2.0 enhanced safety system and dynamic temperature sensor. These features ensure that both your devices and the power bank are kept in optimum health during charging sessions. It offers bi-directional charging, allowing you to charge the power bank and your devices safely.

Performance: Compact Yet Capable

With a 5,000mAh capacity, the Anker Nano Power Bank may seem modest compared to some of its higher-capacity counterparts. However, the trade-off for its smaller capacity is its extreme portability. During my time with it, I found that the 5,000mAh was more than sufficient for day-to-day use, keeping my devices powered during my outings.

Charging times are as impressive as they are stated. My Samsung S23 reached a 50% charge in about 30 minutes. Even when I switched over to my iPad Pro, the charging speeds remained consistent.

There is a small caveat; due to the foldable design, you need to hold both the phone and power bank while charging to ensure a stable connection. A minor inconvenience, but worth noting.


The Anker Nano Power Bank doesn’t disappoint when it comes to compatibility. From the Samsung S22 and S23 Series to the iPad Pro/Air Series, it’s got you covered. For Apple users, it extends compatibility to the iPhone 12, 13, and 14 Series, along with the iPad 9th Generation and the AirPods Series when you use a USB-C to Lightning cable. However, remember that it’s not compatible with phone cases thicker than 4.9 mm.

Conclusion and Rating

So, is the Anker Nano Power Bank the right portable charger for you? If you prioritize portability, speed, and environmental responsibility, the answer is a resounding yes. Its minor limitations, such as the need to hold the device while charging and the 5,000mAh capacity, are outweighed by its robust feature set, sleek design, and impressive performance.

Rating: 9/10

In a market crowded with portable chargers that often compromise on either size or speed, the Anker Nano Power Bank strikes an almost perfect balance. The design is thoughtful, the performance is reliable, and the focus on sustainability is the cherry on top. For these reasons, it scores a high 9 out of 10, making it an excellent choice for anyone in need of a compact, yet powerful, charging solution.
