Magsafe Battery Pack

1. 

Effortless Magnetic Design

• Designed to snap onto the back of MagSafe-compatible iPhones such as the iPhone 12, 13, and 14 series using built-in magnets for secure alignment. No buttons to press or switches to flip—it charges automatically. 
• Works through MagSafe-compatible cases; however, Apple cautions that leather cases may show slight imprints over time. 

2. 

Smart Charging Performance

• Offers up to 5W wireless charging when used on the go; a firmware update later increased it to 7.5W. 
• When plugged into power via its Lightning port (using a 20W or higher USB-C adapter), it boosts charging to up to 15W, charging both the battery pack and iPhone simultaneously. 

3. 

Battery Capacity & Power

• Contains a 1,460 mAh (11.13 Wh) battery, roughly equivalent to:
  
• 70% extra charge for iPhone 12/13 mini,
• 60% for standard and Pro models, and
• 40% for Plus or Pro Max versions. 
• Thanks to its higher operational voltage (7.62 V), it delivers more usable charge than its mAh suggests. 

4. 

Compact & Portable Build

• Slim, rectangular form measuring approximately 96 × 64 × 11 mm, weighing 114–115 grams—lightweight yet compact enough to carry in pockets. 

5. 

Intelligent iOS Integration

• Displays its charge status and the iPhone’s battery level directly in the Batteries widget on the Home or Lock Screen. 
• Supports reverse charging: the iPhone can happily charge the battery pack when the iPhone itself is connected to power. 

6. 

Optimized Battery Health & Safety

• Includes safety features like temperature regulation, overcharge protection, and charge limiting:
  
• Charging may be limited to ~80% or 90% to manage heat and preserve battery lifespan, with notifications to override if needed. 
• Delivers consistent power intelligently, ensuring longevity and safe operation. 

7. 

Usage & Compatibility Notes

• Compatible with iPhone 12, 13, 14, and some later MagSafe models, especially those still using Lightning.
• Requires iOS 14.7 or later to function properly. 
• Discontinued in September 2023 as Apple shifted to USB-C with the iPhone 15 series—no longer available for purchase from Apple.
