Small (Warm Light, Cool Bright)

LED: 6 lights
Belt Colors: White, Black, Orange
Lighting Duration: Approx. 15 hours on low mode, approx. 10 hours on high mode

Fully charges in approximately 5-7 hours of direct sunlight (may take longer depending on charging method, season, and weather conditions).

Note: There is no charge level indicator.

How to use

Before first use, please fully charge the product in direct sunlight.
Gently pull the top and bottom straps to allow air to enter through the air hole, forming a cube shape.
To fold, gently press down from the top to release air through the air hole.

Switch

The round protrusion on the bottom right of the solar panel (black surface) is the switch.
*Warm light is yellow, cool white is blue, and rainbow is red.

Each press of the switch button changes the lighting mode.
*For the Medium size, pressing the button once displays the remaining battery charge. (It disappears after about 5 seconds.) Pressing the button twice activates the "Low" mode.
*For the Small size, pressing the switch once activates the "Low" mode.

Charging Method

Point the solar panel (black side) toward the sun and expose it directly to sunlight.
Charging efficiency will significantly decrease in the shade, on cloudy days, or under indoor lighting, making it almost impossible to charge.
Charging may take a long time depending on the season and weather.

* The sun is constantly moving, so adjust the solar panel to face the sun for efficient charging.
* Solar radiation increases with sunrise and peaks around noon. The most efficient charging time on a clear day is between 10 AM and 3 PM.
* Due to the nature of electronic components, there may be individual differences in charging times.

Charging indoors and through windows

The charging efficiency drops significantly in indoor lighting, making it almost impossible to charge.

Furthermore, passing through window glass causes light energy to be reflected and blocked, which reduces charging efficiency and prolongs charging time.
For efficient charging, please charge in direct sunlight.

In-car charging

High-performance UV-cut glass is used in automobiles, which significantly reduces solar energy and deteriorates charging efficiency, requiring a considerable amount of time for charging.
Additionally, the inside of a car can reach extremely high temperatures regardless of the season, which may cause fatal damage to the battery, so please do not leave it inside the car.

Regarding long-term storage

The built-in lithium-ion battery will gradually discharge even if it is not used at all.
If storing for an extended period, we recommend charging it regularly.
If stored for a long period without any charging, the battery's discharge may cause damage.

Precautions for use

・Do not disassemble or modify the product.
・Do not leave or charge the product in places with high temperatures, such as inside a car.
・Although it is waterproof and dustproof, do not submerge it in water.
・Do not apply strong force or forcibly bend it.
・Store out of reach of small children.

How long should I charge it?

Medium size requires 7–9 hours of direct sunlight. (May exceed 9 hours depending on weather and season)

Small size requires 5–7 hours of direct sunlight. (May exceed 7 hours depending on weather and season)

How long does it stay lit on a full charge?

The approximate lighting time when fully charged is as follows:

　Medium size: 10 hours in strong mode, 42 hours in medium mode, 72 hours in weak mode

　Small size: 10 hours in strong mode, 15 hours in weak mode

　Rainbow: 3-15 hours *Lighting time varies depending on the color.

What is the lifespan (how many years) of the product?

Battery life varies depending on your environment and usage. The product will become unusable when the battery reaches the end of its life.
A typical lithium-ion battery can be recharged approximately 500 times. (One recharge cycle is defined as charging from zero to full.)
While the battery will not immediately become unusable after 500 cycles, you may notice effects such as a shorter illumination time.
Batteries gradually degrade due to various factors, and as degradation progresses, their charging capacity decreases.
You will notice that the illumination time per charge decreases, making you feel that "the battery doesn't last as long, even though I'm using it the same way as always."

The indicator light is flashing even though it's not charging.

The indicator lamp is designed to flash in response to light.
The flashing will stop if you turn the unit face down or cover it with your hand so that light does not hit the panel surface.

Can the battery be replaced or repaired?

Battery replacement, disassembly, or repair is not possible because the unit is integrated with waterproofing and dustproofing.

There's a hole in the product.

This is an air hole, which makes it easy to fold the item.

Water got inside.

The panel is waterproof. Please fold it slowly to drain the water.

The belt is broken, and the fabric is torn.

Applying excessive force may cause the belt to snap or the main unit to tear.
Unfortunately, these cannot be repaired, so please be careful not to apply excessive force.

Is it okay to store it without using it?

If a battery is left unused for a long period, it will discharge and deteriorate more quickly. We recommend regular charging to ensure it's ready when you need it.

There are two light color options, what's the difference?

Warm Light (Warm-color LED): A warm, orangish light.

Cool Bright (White-color LED): A stylish, whitish light.

*Actual colors may vary from those shown in catalogs, other printed materials, or on monitors.

What's the difference between the medium size and the small size?

The size, charging time, and illumination time differ.

Only the medium size has a charge level indicator; the small size does not.

Please refer to the "Product Specifications" for each item for details.
