🔋 What’s mAh All About?
🔋 What’s mAh All About?
mAh stands for milliamp hours—basically, how much "fuel" your battery can hold. A higher or lower mAh than your original battery? No worries! 🙌 It won’t affect charging or operation—just means your device might run a bit longer or shorter between charges. Still 100% compatible. Still 100% awesome. 💪✨
