# Evaluating the Apple MagSafe Battery and Anker Nano Power Bank for iPhone Air
The iPhone Air is recognized for its unexpectedly excellent battery longevity, particularly for individuals with light to moderate daily usage. Nevertheless, for those who are often away from a charger for long durations, such as while traveling, an external battery pack becomes crucial. Two widely chosen options in this category are Apple’s MagSafe Battery and Anker’s Nano Power Bank. This article will examine the design, efficiency, and overall functionality of both products to assist you in deciding which one suits your requirements best.
## Apple MagSafe Battery Design
The Apple MagSafe Battery is crafted specifically for the iPhone Air, showcasing a premium appearance with soft-touch plastic and a padded front plate. It measures only 6.5mm in thickness and encompasses the complete width and height of the iPhone Air, fitting securely beneath the camera bump. This design permits attachment even when the iPhone is encased in a bumper.
The MagSafe Battery lacks visible buttons or displays, depending solely on a single LED to signify charging status when linked to a power source. When connected to the iPhone Air, users can see the battery percentage on the iOS Batteries widget, accompanied by a distinctive MagSafe lock screen animation.
## Anker Nano Design
The Anker Nano Power Bank is also crafted with portability as a priority, showcasing a robust plastic construction. It comes in black, white, or green and features a solo button that activates a row of four LEDs to show the current charge level in 25% increments. The Anker Nano is slightly bulkier at 8.6mm but has a smaller width and height in comparison to the Apple MagSafe Battery. While it might require a little more effort to align with the MagSafe magnets, it remains user-friendly.
## Charging Efficiency
Magnetic power banks like the MagSafe Battery and Anker Nano provide convenience, enabling users to attach them to the rear of their devices for wireless charging. However, wireless charging is inherently less efficient than wired charging, with energy losses around 30%.
Apple’s MagSafe Battery is equipped with specialized software to enhance charging efficiency. While the Anker Nano offers a capacity of 5,000 mAh, Apple’s MagSafe Battery includes a 3,149 mAh battery, which Apple asserts can deliver approximately 65% additional charge to the iPhone Air.
In practical assessments, the Apple MagSafe Battery charged the iPhone Air from 20% to 84% in about 75 minutes. The Anker Nano succeeded in charging the iPhone from 20% to 100% before running out, providing approximately 16% more charge than the Apple battery. This outcome suggests that while the Apple battery is efficient, the Anker Nano’s greater capacity ultimately delivers more power.
## Conclusion
In summary, although the Apple MagSafe Battery offers a luxurious feel and seamless compatibility with the iPhone Air, the Anker Nano Power Bank stands out as the more pragmatic option for users seeking extended battery life. The Anker Nano not only provides greater capacity at a more affordable price but also enables users to monitor the charge status without needing to connect it to the phone.
For individuals who frequently travel or need extra battery longevity, the Anker Nano makes an excellent companion, offering more total battery life than even the iPhone 17 Pro Max. Moreover, the availability of a black color variant makes it a fashionable match for the space black iPhone Air, while the Apple MagSafe Battery is restricted to a white finish.
