In the discharging mode (the KEY function of the charging mode is invalid) trigger the KEY port once to turn on the output; trigger the KEY port 2 times to turn off the output. 2. When the load is connected the output will be turned on automatically. If the load is less than 50MA the output will be turned off after 30 seconds; if the load is greater than 50MA the output will be turned on continuously. 3. Allow charging and discharging at the same time (Note: At this time the output voltage is less than 5V. Stop charging and discharging will also stop. It will be output only after reactivation.)
