Introduction

The Anker Nano Power Bank (A1259) promises a compact yet powerful charging solution. With its integrated USB-C cable and advertised 30W bi-directional fast charging, it’s designed for today’s power-hungry devices. After weeks of rigorous testing, charging various devices from smartphones to tablets, I’m ready to share my in-depth review.

Key Features

The Anker Nano Power Bank (A1259) boasts several notable features, including its integrated USB-C cable, which eliminates the need for carrying a separate cable. The 30W bi-directional charging is a standout feature, allowing for quick charging of both the power bank itself and your devices. The compact size is also a major plus, making it ideal for travel or everyday carry. And lastly, Anker’s commitment to sustainability, using 80% post-consumer recycled plastic (PCR) in its construction, is commendable.

Performance & Testing

I tested the A1259 with a range of devices, including an iPhone 14 Pro, a Samsung Galaxy S23, and an iPad mini. The 30W charging speeds were largely consistent with Anker’s claims. Charging my iPhone 14 Pro from 0% to 50% took approximately 35 minutes, which is very impressive. Charging the power bank itself was also fast, taking roughly 45 minutes to reach 50% capacity. I also appreciated the dual-port functionality which allowed for charging two devices simultaneously, although the charging speeds were slightly reduced when doing so.

During extended use, the power bank remained relatively cool, even during rapid charging sessions. The build quality feels premium and robust despite the use of recycled materials. The integrated USB-C cable is a clever design element that proves convenient and reliable. However, I did notice a slight reduction in charging speed when using non-PD enabled devices. In addition, the LED indicator is relatively low, providing basic information about the power level, but more granular detail would be a welcomed addition.

Pros & Cons

• Pros: Fast charging speeds, compact design, integrated USB-C cable, dual charging ports, sustainable materials, reliable performance.
• Cons: Slightly reduced charging speed when charging multiple devices simultaneously, minimal LED charging indicator, slightly more expensive than some competitors

Final Verdict

The Anker Nano Power Bank (A1259) is a compelling portable charger. Its fast charging speeds, compact size, and integrated USB-C cable make it a convenient and practical choice for anyone who needs reliable power on the go. While it’s slightly more expensive than some competitors, the improved charging capabilities and eco-conscious design justify the price premium for many users. I highly recommend it to users who prioritize speed and convenience.
