Caring For Your LightSaver

Avoid Physical Damage

The LightSaver’s solar material is thin, light and durable, 

but creasing or puncturing the solar panel will reduce 

efficiency. Reasonable care in handling will assure a long 

life. 

Charging Temperatures

Avoid leaving the LightSaver on the dash of a hot car or in 

other similarly hot environments as the heat may damage 

the battery. 

The LightSaver charges most effectively between 35 and 

115 degrees Fahrenheit.

Avoid Excessive Water

A little water on the LightSaver is not a problem, but 

allowing significant water inside the unit may corrode 

components. Saltwater is particularly corrosive and should 

be kept out of the device. 

Battery Care

If your LightSaver’s battery is completely drained, it may 

need to charge for a few minutes before the indicator light 

illuminates. 

Always store your LightSaver with a battery charged over 

50% in a cool environment. 

The LightSaver will give you many years of excellent service 

with proper battery care. 

Mounting

The LightSaver features four attachment points allowing it 

to be mounted securely on a backpack, tent, etc. Keep in 

mind the expected direction of the sun when choosing 

where to mount the LightSaver. The easiest and most 

effective approach is usually to mount horizontally. 

(Example: mounting on the top of a backpack rather than 

the back is better). The LightSaver’s solar panel is far more 

tolerant to shading than most solar devices, but any 

shade will reduce the amount of energy collected. If you 

are mounting the LightSaver on the top of a tent, choose 

a location which will face the sun for the longest portion 

of the day.

Maximizing Use of the Sun

Facing the unrolled LightSaver directly toward the sun 

results in the maximum amount of energy collection. A 

day’s worth of exposure, 6-8 hours, on a mostly sunny day 

while laying horizontaly should give you a full charge. 

Clouds and haze reduce the sunlight that reaches the 

LightSaver. Windows reflect a portion of the sunlight, so a 

LightSaver sitting on a windowsill will take longer to 

charge than if it were sitting outside at the same angle. 

Car windows, particularly windshields, block a significant 

amount of light. 

Charge Indicator

The LightSaver’s charge indicator turns on when there is 

electrical current flowing from either the solar panel or 

the micro USB input to the battery and turns off at all 

other times to conserve battery.
