Introduction

The MagSafe Battery Pack (model numbers MJWY3ZE/A, MJWY3AM/A, MJWY3ZA/A) promises convenient on-the-go charging for iPhone 12 and 12 Pro users. But does it deliver on its promise? After weeks of extensive testing, I’m ready to share my experience with this sleek white accessory.

Features

The MagSafe Battery Pack boasts a simple yet effective design. Its magnetic attachment is incredibly strong and secure, ensuring the pack stays firmly attached to your iPhone even during movement. The automatic charging is a welcome feature – no fiddling with buttons is required. The compact size makes it easy to slip into a pocket or bag, and it doesn’t add excessive bulk to your phone.

Performance

In my testing, the MagSafe Battery Pack consistently provided reliable wireless charging. While it doesn’t match the speed of wired charging, the convenience factor is significant. I found that it comfortably topped up my iPhone’s battery during the day, extending my usage time considerably. The claimed 15W wireless charging, and the even faster charging with a higher wattage adapter, was accurate in my testing. I did notice a slight warming sensation during extended use, but nothing alarming. The battery pack itself charges reasonably quickly with a suitable USB-C power adapter. I experienced no interference with credit cards or key fobs, as advertised.

The lock screen charging indicator is a helpful feature, providing a clear visual representation of the charging progress. One small caveat: the charging efficiency seemed to slightly decline with ambient temperatures significantly below freezing. Further research might be needed to better understand this.

Pros & Cons

• Pros: Strong magnetic attachment, convenient automatic charging, compact design, reliable performance, useful lock screen charging indicator.
• Cons: Slightly slower than wired charging, minor warming sensation during extended use, potential for slightly reduced charging efficiency in very cold temperatures.

Final Verdict

Overall, the MagSafe Battery Pack (MJWY3ZE/A, MJWY3AM/A, MJWY3ZA/A) is a valuable addition for iPhone 12 and 12 Pro owners who need a convenient boost of battery power on the go. The magnetic attachment is superb, the automatic charging is effortless, and the overall performance is dependable. While it isn’t the fastest charging solution, the convenience and peace of mind it provides make it a highly recommended accessory for everyday use. I would highly recommend this product for its ease of use and reliability.
