6.5 Power Bank Function (Charging External Devices)
Your XSY-350 radio can act as a power bank to charge your mobile phone or other USB-powered devices.
- To Charge: Open the rubber cover on the side, connect your device to the USB Output Port using a compatible USB cable.
- Indicator: When the radio is discharging (acting as a power bank), the blue power indicator lights will gradually diminish.
- Note: This function is primarily recommended for emergency use. If your device does not start charging, disconnect and reconnect the USB cable to reactivate the power output.
7. Power Methods & Charging
The XSY-350 offers multiple ways to ensure you always have power:

7.1 USB-C Charging
- Method: Connect the supplied USB cable to the Type-C Input Port on the radio and a USB power source.
- Indicators: Four blue power indicator lights will light up in sequence during charging.
- Charge Time: Approximately 5.5-6 hours for a full charge.
7.2 Hand-Crank Charging
- Method: Extend the hand crank handle and rotate it clockwise or counter-clockwise.
- Recommendation: For optimal charging, spin the handle at approximately 120 RPM.
- Usage: 3 minutes of cranking can provide enough power for 4 minutes of flashlight use or 15 minutes of radio operation.
- Note: Hand-crank charging is primarily recommended for emergency situations. A full charge via hand-crank can take up to 53 hours.
7.3 Solar Charging
- Method: Place the radio with the solar panel facing direct sunlight.
- Indicators: A red power indicator light will illuminate when the radio is receiving sufficient sunlight for charging.
- Purpose: Solar charging is most effective for maintaining the battery charge and prolonging its overall lifespan, rather than for rapid full charging.
7.4 Power Indicator
The radio features four blue LED lights to indicate the remaining battery capacity:
- 1% - 25%: 1 steady light on
- 26% - 50%: 2 steady lights on
- 51% - 75%: 3 steady lights on
- 76% - 100%: 4 steady lights on
When fully charged, all four blue indicators will be steady, and the red charge indicator (if active) will change from blinking to steady.
8. Maintenance
- Battery Maintenance: Charge the radio at least once every three months. If the unit has been idle for over 60 days, hand crank for 1 minute to reactivate the internal battery.
- Cleaning: Wipe the radio with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the radio in a dry, cool place away from direct sunlight and extreme temperatures.
9. Troubleshooting
- Radio Not Turning On: Check the battery level using the power indicators. Try charging the radio via USB-C, hand-crank, or solar power.
- Poor Radio Reception: Fully extend the telescopic antenna. Try moving to a different location, especially outdoors or near a window, to improve signal strength.
- External Device Not Charging (Power Bank Function): Ensure the radio has sufficient charge. Disconnect and reconnect the USB cable to the USB Output Port to reactivate power output.
- Flashlight/Reading Lamp Not Working: Check the battery level. If the battery is very low, the lighting functions may be disabled to conserve power.
