Working time = 1210Wh * 0.9 / device's operating power

For example: assuming the device's power consumption is 300W, the working time is 518Wh * 0.9 / 300w = 1.56 hours (approximately)

How do I use the AC output?

Press the power button 3 seconds to turn the unit on. Short press the AC button, the LCD screen will light up with AC indication, you can use the AC outlet, press the AC button again to exit the AC output.
