4. Charging Methods
The XinFuture Smart WiFi Solar Sprinkler Timer offers two convenient charging methods:
- Solar Charging: The integrated solar panel efficiently converts sunlight into energy to charge the internal super capacitor (4V 550F). Place the timer in direct sunlight for approximately 1 hour for a full charge.
- USB Charging: For situations with limited sunlight or faster charging, connect the device to a 5V 1-3A USB adapter via the Type-C port. A 10-minute charge via USB is typically sufficient. To access the charging port, twist the top half of the device.
A fully charged battery can last up to 15 days with one watering cycle per day without additional sunlight.
