2, Indicator light: the red light turns on during charging, and the green light lights up when charging is complete.
3, Up to two Joy-con at the same time charge, each handle charging current in 200ma.
4, Each charging port, allowing the maximum current through 400ma, if over 400ma, the charging port will be over-current protection, red right flash instructions, pull out the handle, the over-current state would recovery.
5, Charging:
1) Charge in the order of channels 1, 2, 3, 4
2) The latest insert one is the earliest to start charging
6, Rotating charge: according to the principle of priority charging, the combination of two pairs of charging, switching time of 10 minutes. For example, the last time the 1/2 handle is charged, the next 3/4 handle is charged. The corresponding position of the handle is fully charged, uninterruptible power supply.
7, Low voltage overvoltage mode: Red LED slow flash.
Voltage below 4.2v into low voltage mode, the voltage is greater than 4.7v back to normal.
Voltage higher than 5.6v into the overvoltage mode, the voltage is less than 5.3v back to normal.
8, Overtime charging: Joy-con can be fully charged in about 3 hours, if Joy-con is charging 4.5 hours still not fully, then bright green right.

Re-plug the fully charged handle, at least need to more than 30 seconds, the red right turn to green right.
