Setup Guide

Before first-time use, you must fully charge the power bank to ensure optimal battery performance and longevity . Connect a USB-C cable to a USB PD power source, such as the Adapt4 USB-C Charging Station or a standard wall charger with 45W+ output, and plug it into the USB-C input port on the power bank . The device supports input voltages of 5V, 9V, 12V, 15V, and 20V DC, automatically adjusting to the source .

Configuration and Pairing: The power bank does not require software pairing; it connects via physical USB-C or USB-A ports. To charge a device, connect the included USB-C to USB-C cable (or appropriate emulator adapter for older devices like HP Chromebooks or Microsoft Surface) to the power bank's output port and the device's charging port . The Quick-Sense technology automatically detects the device's power requirements and delivers up to 45W for input or 65W for output .

Safety Warnings: Do not expose the unit to temperatures exceeding 60°C or below 0°C. Avoid submerging in water. Ensure cables are USB-A or USB-C compatible; incompatible cables may prevent charging . If the device feels excessively hot during charging, disconnect immediately and allow it to cool .

Troubleshooting Tip: If the device does not charge, verify that the input source provides sufficient wattage (minimum 45W recommended) and that the cable is not damaged .

Troubleshooting

Common Problems and Solutions:

Device Not Charging: Ensure the USB-C cable is firmly connected and compatible with USB PD 3.0. If using an older device (e.g., HP Chromebook G1), verify the correct emulator adapter cable is attached .
Slow Charging Speed: Confirm the device supports Quick Charge 3.0 or USB PD. If using a non-compatible charger, the speed will default to standard 5V charging .
Battery Not Holding Charge: Fully recharge the power bank for at least 4–6 hours before reuse. If the issue persists, the battery may be degraded.

Error Codes: The power bank uses LED indicators to show status. A red light typically indicates low battery or charging in progress, while a green light signifies a full charge. No specific numeric error codes are displayed; rely on LED behavior .

Preventive Measures: Store the unit in a cool, dry place and avoid dropping it. Regularly inspect cables for fraying to prevent connectivity issues .

Warranty and Support: The jar system Active Charge Power Bank includes a 1-Year Limited Warranty on the unit and cables . For technical assistance, contact JAR Systems Support at (866) 393-4202 or visit www.JAR-Systems.com/Support .
