• DC 5521: Input (12-24V MPPT) and Output (Adjustable voltage).
• Wireless Charging Pad: 10W output.

Charging the Power Bank

You can recharge the Gravity 27 Pro using two methods:

• USB-C PD: Use a PD-capable wall adapter (up to 60W recommended) and the included USB-C to USB-C cable.
• Solar Charging: Connect a compatible solar panel (12-24V DC) to the DC 5521 input. For best results, use the Fusion 60, Fusion 100, or Fusion Flex 24 & 48 panels. Place the unit in direct sunlight and avoid shadows.

Charging Your Devices

The power bank can charge up to 5 devices simultaneously. Ensure you use cables rated for your device's voltage and current requirements.

• Laptops/Tablets: Connect to the USB-C1 (100W) port or use the DC 5521 output with an adapted cable.
• Smartphones/Accessories: Use the USB-C1, USB-C2, USB-A ports, or the wireless charging pad.

Adjustable Voltage Output

To use the DC output for specific devices:

1. Long press the Voltage Button.
2. Short press the button to select the desired voltage.
3. Wait 5 seconds for the screen to stop blinking; the voltage will be selected and locked.

Pass-Through Charging

The Gravity 27 Pro supports pass-through charging, allowing you to charge your devices while the power bank itself is being charged (e.g., via solar or USB-C input). Note that charging speed may reduce slightly during this process.

Safety and Maintenance

• Storage: Recharge the unit at least once every 3 months and store it at approximately 80% charge to prevent battery damage.
• Handling: Do not puncture, throw, drop, bend, or modify the unit. Keep away from water, fire, and excessive heat.
• Connections: Do not use excessive force when connecting or disconnecting cables. Keep ports free from dust and lint.
• Abnormalities: Stop using the device immediately if it generates an unusual smell, heats up excessively, or shows signs of distortion.
