- Ensure the AC output is activated by pressing the AC SWITCH button.
- Verify that the device's power consumption is less than 300 Watts. Overload protection will shut down the AC output if the limit is exceeded.
- Check if the power station's battery level is sufficient.
- Power Station Not Charging:
- Ensure the charging cable (AC adapter, car charger, or solar panel) is securely connected to both the power station and the power source.
- Verify the power source is active (wall outlet, car socket, or sufficient sunlight for solar panel).
- Check the input wattage displayed on the LCD screen to confirm charging activity.
- Unit Tidak Dihidupkan:
- Ensure the battery is not completely depleted. Try connecting it to a charger.
- Press and hold the POWER button for a few seconds to ensure it registers.
6.2 CPAP Machine Working Time Calculation
The working time for a CPAP machine depends on its power consumption. For an approximate calculation:
Working time = 296Wh * 0.85 / operating power of your device (in Watts)
Untuk example, if your CPAP machine consumes 50W, the running time will be approximately 296Wh * 0.85 / 50W = 5 hours. This calculation assumes the heater and humidifier functions of the CPAP machine are turned OFF, as these significantly increase power consumption.

Estimated working times for common CPAP machines (heater & humidifier OFF).
