Precautions

TEMPERATURE & CHARGING

• Output is automatically controlled based on internal temperature. Select the 7.5W mode when you want to reduce heat.

WHEN TO STOP USING
• If the power bank or smartphone becomes too hot to hold, or you notice a burning smell or unusual sounds, stop using immediately and contact customer support.

CASES & MAGNETIC ATTACHMENT
• Case material and thickness can affect magnetic attachment and wireless charging. Some cases may prevent stable attachment or charging.
• When using a case, use one supplied by the smartphone manufacturer as recommended in the product guidance.

CHARGING SPEED
• Charging slows as the device or power bank approaches full charge.
• Speed depends on the device, cable, battery level and usage conditions. Fast charging is not available in every configuration.
• Simultaneous and pass-through charging may take longer than charging one device alone.

SIMULTANEOUS OUTPUT
• When wired and wireless charging are used together, USB-C output is limited to 15W and wireless output to 5W.
• The maximum 35W wired and 25W wireless outputs are not available simultaneously.

• During device charging, the display alternates between battery percentage and the selected mode. This is normal operation.
