If your power station isn't working correctly, insert a paper clip or pin into the reset hole for 1 second for a factory reset. If
the power station still doesn't work, please contact support@anker.com.
Q5: Why is the power station not working after it hasn't been used for a long time?
If the power station is stored at a low capacity for a long time, lithium batteries will self-consume power which may lead
to a quick discharge. This often leads to poor conductivity and a reduced battery lifespan that causes the battery not to
work.

When storing your portable power station, please make sure that you:
1) Turn o the main power button.
2) Store the power station in a dry and cool environment.
3) Check the remaining battery capacity each week. If the battery level is below 30%, fully charge the power station. Don't
forget to charge it to 100% once every 3 months.
Q7: Does the power station have to be used upright?
Yes, the product needs to be used and stored upright.
Q8: When will the output ports of Anker SOLIX C300 DC Portable Power Station automatically shut down?
The output ports shut down under these two conditions:
1) USB-A and USB-C4 Ports: If there is no input to the power station and the total output current of the connected load is
less than 60mA for two hours, the ports will shut down.
2) USB-C1, C2 and C3 Ports: If there is no input to the power station and the output current of the connected load is less
than 100mA for two hours, the ports will shut down.
Note that the time cannot be changed. To reactivate the ports, unplug the connection cable, then plug it back in.
Q9: Why didn't the Anker SOLIX C300 DC automatically shut down after I set the device timeout to 30 minutes?
Anker SOLIX C300 DC Portable Power Station automatically shuts down under these two conditions:
1) If "Device Timeout" is NOT set to "Never" in the Anker app.
2) If there is no input to the power station and all output ports are o, C300 DC enters sleep mode, then shuts down
according to the set time for device timeout. This timing does not begin when device timeout is set.
To exit sleep mode, please perform the following actions:
