💡 Shipping heavy or bulk items?

If your order includes multiple heavy products, we recommend requesting a custom quote — we may be able to arrange a better rate with a transport truck! 

Please note: We reserve the right to send heavier items by transport truck if the carrier's maximum weight per package is exceeded or if we consider it too risky to place with a courier due to the possibility of damage occurring.

🔋 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. 💪✨

Before ordering please read

Ensure the original battery model number is mentioned in our product description and verify that your device model number is also listed in the description.
