The Sprout Foldable Solar Panel Charger is an Australian-owned brand product designed to provide portable and sustainable power for your digital life. It features a built-in lithium-ion polymer battery that captures power directly from sunlight or can be charged via mains power. The foldable design enhances portability and optimizes solar capacity, making it suitable for outdoor use. The durable Nylon housing includes built-in pockets to protect each panel and maintain a dust-free environment.
Function Description:
The primary function of the Sprout Foldable Solar Panel Charger is to convert sunlight into electrical energy to charge its internal battery and, subsequently, other mobile devices. It can also be charged via an AC adapter. The device is equipped with iSolar technology, which intelligently detects sunlight intensity to optimize current conversion for maximum power output. Multiple built-in protections, including charging control and cut-off technology, ensure safe charging. The charger supports a wide range of 5V USB-powered devices, such as external battery packs, tablets, and mobile phones, with the exception of Bluetooth devices under 50mA.

Usage Features:
- Recharging the built-in battery (solar): Place the solar panels under direct sunlight, adjusting the angle towards the sun (vertical direction) for optimal charging. Ensure panels are directly exposed to the sun without any shelter or shading. LED indicators will show the current battery level when sufficient sunlight is present. All LED indicators will illuminate when fully charged and turn off automatically when sunlight is insufficient.
- Recharging the built-in battery (AC charger): The battery can also be charged using a wall charger with a 5V 2A AC adapter.
- Connecting multiple chargers: A maximum of three (3) Foldable Solar Panel Chargers can be connected to increase charging speed.
- Charging mobile devices: Before charging, inspect the charger and cables for any damage. Use the provided USB Type-A to USB Type-C charging cable or another certified cable to connect the charger to your device. Confirm charging on your device; if not, unplug and replug or try a different cable.

Maintenance Features:
- Battery lifespan: To maximize the built-in battery's lifespan, fully recharge it at least once every 90 days.
- Heat during charging: It is normal for solar panels to heat up when recharging via solar energy. The panel has built-in protection to stop charging in high-temperature environments to ensure safety and protect the equipment.
- Cable usage: Always use the provided cable or other certified cables to ensure optimum performance.
- Cloudy days: The charger may not support simultaneous charging and discharging due to insufficient sunlight. Performance will be reduced on cloudy days.
- Storage: Store the Foldable Portable Solar Charger in a cool, dry place when not in use. Remove all cables before storing.
- Handling: Solar panels are not bendable. Handle with care and avoid hard knocks or piercing the panels with sharp objects.
- No user-serviceable components: Do not attempt to open or service the charger as it contains no user-serviceable parts.
- Environmental precautions:
- Avoid leaving or using the charger in areas where temperatures may exceed 50 degrees Celsius, such as inside a closed car on a hot day.
- Do not expose the charger to rain, liquids, or high humidity environments.
- Avoid fire.
- Avoid liquid.
- Keep dry.
- No squeezing.
