Initial Charging

Before first use, it is highly recommended to fully charge the power bank via a wall adapter using one of the available input ports (Type-C, Micro USB, or the built-in USB-A cable). This ensures the internal battery is fully activated and calibrated for optimal performance.

• Connect a compatible USB wall adapter (not included) to the power bank using either the built-in USB-A input cable, a Type-C cable, or a Micro USB cable.
• The digital display will show the charging progress. Allow the power bank to charge until it reaches 100%.

Operating Instructions

Charging Your Devices

The power bank offers multiple ways to charge your electronic devices.

• Using Built-in Cables:
  • Pull out the integrated iOS, Type-C, or Micro USB output cable.
  • Connect the appropriate cable to your device's charging port.
  • The power bank will automatically begin charging your device.
• Using USB-A Output Port:
  • Connect your device's charging cable to the USB-A output port on the power bank.
  • Connect the other end of your cable to your device.
• You can charge multiple devices simultaneously using a combination of the built-in cables and the USB-A output port.

Solar Charging Function

The solar panels are designed for emergency power and supplementary charging, not as a primary charging method due to the inherent limitations of solar conversion speed.

• Unfold the four solar panels completely.
• Place the power bank in direct sunlight. Ensure the panels are facing the sun for maximum efficiency.
• The solar charging indicator on the display will illuminate, indicating that solar charging is active.
• For outdoor activities, you can hang the power bank on your backpack using the drawstring hole to charge while on the move.

Using the LED Flashlight

The power bank features two bright LED flashlights with multiple modes.

• To Turn On/Off: Press and hold the power button for approximately 3 seconds.
• To Cycle Modes: Once the flashlight is on, short press the power button to cycle through the modes:
  • Standard Brightness
  • Strong Brightness
  • SOS Mode (Morse code for distress)
  • Strobe Mode (rapid flashing)
• To turn off the flashlight from any mode, press and hold the power button again for 3 seconds.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the surface of the power bank. Do not use harsh chemicals or abrasive cleaners. Ensure solar panels are clean for optimal performance.
• Storage: Store the power bank in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, charge the power bank to about 50-70% every 3 months to preserve battery life.
• Battery Care: Avoid completely draining the battery frequently, as this can reduce its lifespan. Recharge the power bank when the charge level is low.
