Please press the capacity button to check the remaining power on the LCD screen. The product can be charged and discharge at the same time. It can be working without being fully charged.
No. Since the product contains a large volume of lithium-ion batteries with a maximum power capacity of 540Wh, it is deemed as a dangerous article by civil aviation authorities.
Please check the output data on the LCD to calculate the duration.
The calculation formula is:
the maximum power capacity of the product /rated power of the device to be charged × the conversion efficiency of the product
By the output of the product with a maximum power capacity of 540W·h, your electronic device with a rated power of, say, 100W can continuously run for 540Wh/100W×0.8=4.3h. (note：0.8 represents the conversion efficiency of the product.)
Yes. We apply pure-sine wave on our portable power stations, providing more stable power for your appliances.
