The 3-Color LED Indicator
A: When charging the built-in battery:
Red light: Low voltage < 3.8V.
Orange light: Mid voltage between 3.8V - 4.1V.
Green light: High voltage, fully charged.
Remarks: It is normal to see LED indicator flashing in Red, Orange and
Green color during the charging process.
B: When discharging the built-in battery:
Red light: Low voltage < 3.5V.
Orange light: Mid voltage between 3.5V - 4.1V.
Green light: High voltage between 4.1V - 4.2V.
Remarks:
1. When Control Switch is turned ON and is NOT charging any external
device, the LED indicator turns RED indicates that the power is low and it
requires charging immediately (using direct sunlight or power adapter).
2. When Control Switch is turned ON and while charging an external device,
LED indicator will flash in Red, Orange and Green color.
3. When Control Switch is turned ON and there is no LED indicator, it
indicates that the power is low and it requires charging immediately (using
direct sunlight or power adapter).

Using aigo Portable Solar Charger S2902
IMPORTANT:
To stabilize the built-in battery on the solar charger, we would
recommend the following:
1. Use up the remaining power on the new solar charger until the
built-in battery is totally flat (Example: Connect it to a mobile phone and
starts charging).
2. When the built-in battery has finally gone flat, starts charging the
new solar charger for at least 12 hours using the power adapter (repeat
this process for the very first 3 times when using the new solar
charger).
Under direct sunlight, the product transforms light energy absorbed by
solar panel into electric energy and through the control circuit to store
electric energy in the built-in battery, or directly charge cell phone or
other digital products with the electric energy (It depends upon the
sunlight intensity. If the electronic mobile equipments need high current,
may cause no charging to external electronic products). During the
absence of sunlight, the product can be charged with the bundled
power adapter, and it also can charge other devices at the same time.

1). Charging under direct sunlight
a. Open the cover on the solar charger and keep solar panels upright
facing direct sunlight.
b. Turn Control Switch to OFF position.
Note: When the 3-Color Indicator turns Red color, it indicates that the
built-in lithium battery is being charged and voltage is under 3.8V;
if the light turns Orange color, the storage capacity is larger and the
voltage is between 3.8V - 4.1V;
if the light becomes Green color, it means the built-in battery is full.
When the cover on the solar charger is closed, the 3-Color Indicator is
OFF and the solar panel stops working.
2). Charging using power adapter
a. Connect the cable of the power adapter to the DC interface on the
solar charge.
b. The 3-Color Indicator will turn Red color. The 3-Color Indicator will
flash in Red, Orange and Green color.
c. When the 3-Color Indicator turns Green color, it indicates that the
internal built-in battery is fully charged.

3). Charge an external portable digital device
a. Set the Output Voltage to the most suitable voltage level according
to your electronic equipments charging voltage.
b. Select the correct charging connector which is suitable for the
electronic equipments and connect the electronic equipment to the
charging connector and solar charger (through the USB cable).
c. Switch the Control Switch to ON and 3-Color Indicator turns Red (the
LED indicator will flash in Red and Green color) to indicate charging is
in progress.
d. When the battery indicator on the external electronic mobile
equipment indicates fully charged, please switch Control Switch on the
solar charger to OFF and disconnect the power adapter (Please
change setting to 6.3V for Nokia mobile phones if it is not charging).
Note:
1. Before using the solar charger, please charge it for more than 12 hours
using power adapter for the first three times (see page 11).
2. When LED indicator flashes in Red and Green color, it means that the
sunlight intensity is low. However, we may also charge using the power
adapter.
