For AC outlet not charging issue:

If your power station is charged fully, but the AC outlet can't charge the connected device, please refer to the following article to find out the root causes.

For the car socket not charging issue:

If your power station is charged fully, but the car socket (DC port) can’t charge the connected device, the power requirements (Watts) of the connected device might exceed the maximum output of the car socket (DC port).

 

Please make sure that the device connected to the car socket (DC port) requires less than its maximum output. You can also try to plug a car charger into the car socket (DC port) and then charge your phone to see if it works.

 

For the USB-A/USB-C port not charging issue:

If your power station is charged fully, but the USB-A/USB-C ports cannot charge devices, try a different cable and device.

 

There may be incompatibility issues if the USB-A/USB-C ports can charge phones but cannot charge other devices, such as cameras.

 

For the discharging quickly issue:

If the power station discharges quickly when not in use, when the AC power button is turned on, even if no devices are being charged, there will still be a certain amount of no-load power consumption.

 

We recommend turning off the button when you are not using the power station. If the issue persists, please charge the power station fully, turn off all ports, and leave it unused for 1-2 days to see if you have the same issue.

 

For 757 Power Station 1229Wh, if it discharge quickly when not in use (4%-5% every day):

• Check the power level first (such as 70%). 
• Use a pin to click the reset port ( the reset port is on the top of the power saving button). 
• Leave it unused for 24 hours, then try to check the power level to see if the same issue happens.

Abnormal screen issue: 

If the display only shows 100% or 0%, or if you find the battery discharges quickly within several minutes, such as dropping from 20% to 0% very quickly, please try the following steps to calibrate the power station:

• Discharge the power station to 0%. Then, charge the power station to 100%. Do not use it for 5 hours, and try charging your devices to see if the same issue persists.
• The display will calibrate automatically by discharging the power station to 0% and charging it fully. Please also refer to the following article to reset the power station.
