Battery Care Reminder:

For products with built-in rechargeable batteries: if the item has been stored or unused for a long period, the battery may become temporarily unstable or appear less durable due to voltage imbalance during storage.

After receiving the product, please let it sit at room temperature for about 10–20 minutes to allow the battery voltage to stabilize before charging. Then fully charge the device before first use for optimal performance.

To extend battery lifespan:

• Do not leave the device plugged in for long-term storage.

• Avoid fast charging or high-power rapid charging adapters.

• Use a standard, compatible charger only.

Proper charging and storage will help maintain stable performance and longer battery life.
