Important Notes for Optimal Performance

• Activating Trickle Charge Mode: For small accessories (wireless earbuds, fitness trackers, smartwatches), please double-press the power button to enter Low-Current Mode. This ensures safe, slow charging that preserves delicate battery health.

• Maximizing 65W Speed: To achieve full 65W laptop charging speeds, ensure you are using a 65W or higher rated USB-C cable (the included cable supports fast charging) and that your device supports USB-C Power Delivery (PD).

• Recharging the Power Bank: For fastest recharge of the power bank itself, use a 65W or higher USB-C PD wall charger (wall adapter not included).

• Temperature Notice: It is normal for the power bank to feel warm when charging multiple devices at high speeds or during 65W output. The intelligent chip actively manages temperature to ensure safe operation.

• Capacity Clarification: The rated capacity of 20000mAh refers to the internal battery cells. The actual output capacity delivered to your devices varies based on voltage conversion and cable efficiency (typically 65-75% of rated capacity), which is standard for all power banks.
