we can supply all kinds of solar chargers , you can use it to transport the powder to your cell phone, DC,DV and so on. Technical parameter TYN-91,TYN-97 1)　Solar panel: 　　Power：1.65W 　　Voltage　：5.5V 　　Current　：300MA 2) Full charger: Battery capacity ：2000MAH/3.7V Output voltage：4.5V～9V（can be adjusted） Output current：1A（max） Output power ：3W Size：125x81x24mm Weight：216g Application Scope: It is suitable for 98% cell phones and electronic mobile equipments whose charging voltage ranges from 4.5V to 9V. As different electronic products have different charging volt and current, please choose right volt level before charge the electronic mobile equipments. Working Principle: Under Sunlight, the product transforms the light energy absorbed by solar panel into electric energy and then 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 mobiple equipments need high current, may cause no charging to external electronic products). In the absence of sunlight,the product can be charged with a DC adaper, and it also can charge other devices at the same time. Operation Instruction: 1)Charge under the sunlight: This is the process to charge the built-in battery. Firstly, open the cover, keep the solar panels facing the upright sunlight, put the function switch "10” to "OFF”,then the indicator will become "red”, which means the lithium battery is being charged and the voltage is under 3.8V; if the light becomes "orange” the volume of electric capacity is larger, the volt is between 3.8-4.1V. When the light becomes "green”, means the built-in battery is full. 2)Charge the portable digital device: This is also the process to charge the inside battery. Connect the DC adapter to solar charge by plugging the cable of the adapter into DC port. Then connect the adapter to DC power(110V or 220V), then the indicator will become "red”. The indicator will go through ted,orange and become green at last. When the indicator become green, it indicates that the internal battery is fully charged, please disconnect the adapter. 3)Charge the portable digital device: This is the process to charge electronic mobile equipments. Firstly switch the voltage option switch "5”to the suitable volt level according to your electronic equipments charging voltage, then select the right connector which is suitable for the electro nic equipments, and then connect the electronic equipment, adaptor and the solar charger through the USB cable, at last switch the control switch "10” to "ON”. The indicator will become red(if appears the red and green light in turn, it is normal). When the charging indicator of your electronic mobile equipments is on, that means the charger is at work. When the electronic mobile equipment is fully charged, please switch the control switch "10”to "OFF” and pull out the cable from the charger(please switch to 6.4V for Nokia mobile phones). In addition, you also can open the cover under the sun to charge the built-in Li-battery as stores. Note: 1. In order to activate the built-in battery, please charge the electronic product for more than 12 hours by DC for the first three times. 2.if appears the red and green light in turn, means the sunlight intensity is not so good. Notice: 1.Continue charge the charger with powerful sunlight, 8 hours can charge fully the built-in battery. 2.Don’t put charger in the car when charge(the tempreture in the car is too high) in summer, will damaged the battery. 3.Don’t charge through glass, the sunlight power is worse. 4.Must charge within power light, if the light is weak, Light 1 will be turn on, but mean it is charged. 5.Please wipe wet surface with the towel, don’t toast it on fire. 6.Don’t litter the product into fire, to avoid causing explosion.
