Getting Started

First, charge the internal power bank via wall adapter before initial solar use.

Charge Power Bank: Connect USB-C cable to wall charger (5V/2A) and power bank input port. LED indicators will show charging progress.
Unfold Solar Panels: Open fully and position towards direct sunlight.
Connect Device: Use your own USB cable to connect device to one of the USB output ports.
Begin Charging: The solar charger will automatically start charging your device.

Tip: For fastest charging, pre-charge power bank via wall outlet.

Charging Operation

Supports simultaneous charging of two devices. Smart IC adjusts output per device.

Solar Charging: Place in direct sunlight, adjust angle every few hours for best results.
Dual Device Charging: Connect two devices; output will be shared intelligently.
LED Behavior: Flashing = charging in progress; Solid = fully charged or standby.
Low-Light Operation: Charging slows in cloudy/shaded conditions.
Power Bank Mode: Use stored energy when sunlight is unavailable.

WARNING! Do not leave devices unattended while charging in extreme conditions.

LED Indicators & Status

Four LED lights indicate internal power bank level and charging status.

LED Pattern	Meaning
All LEDs off	No power / sleep mode
1 LED flashing	0-25% battery, charging
2 LEDs flashing	26-50% battery, charging
3 LEDs flashing	51-75% battery, charging
4 LEDs flashing	76-100% battery, charging
All 4 LEDs solid	Fully charged / standby
Single LED blinking fast	Short circuit / overload protection active

Care & Maintenance

Unfold and wipe solar panels with dry, soft cloth. Store in dry place.

Cleaning: Use only dry cloth on solar panels. Do not use chemicals or abrasive materials.
Storage: Keep in cool, dry location. Fold neatly after use.
Battery Care: Fully charge and discharge power bank every 3 months if not in regular use.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Device not charging	Low sunlight / bad connection	Move to direct sunlight; check USB cable and port connection.
LED indicators not lighting	Battery completely drained	Charge via wall outlet for 2 hours; then try solar.
Slow charging	Cloudy day / panel angle	Adjust panel perpendicular to sun; ensure no shadows.
Charger gets hot	High ambient temperature	Move to shaded, cooler area; allow to cool before resuming.
Power bank not holding charge	Battery needs conditioning	Fully charge then fully discharge (use until off) 2-3 times.

Reset: Disconnect all devices, fold and unfold panels, restart.
