Copenhagen is crowded with people, delegates from nearly 200 countries, journalists, activists, and observers. So many people are focusing on one topic: environment. People talk, argue, and even quarrel to hammer out a deal aimed at slowing global warming. It seems a considerate amount of time after people began to care about the environment. However, people did not take the problem so seriously till we suffer from it. http://www.sunvalleyus.com/ How many times do you find the term “green technology” repeatedly appears in the news? Do you experience the green technology yourself? How can we apply it in daily life? Here we introduce you a simple solution: solar charger. The high-performance solar panel coverts solar energy into electricity and it can recharge your mobile phones in 3-4 hours. It is also applied to MP3 player, digital camera and other digital items which are popular in travel. Bring this gadget and you would never worry about running out of juice. The following is FAQ about solar charger. Q: How to ascertain the actual power of solar panel? A: You can judge based on the surface area and packing density of solar panels. Usually, a 10cm x 10cm panel can achieve 1.5W power in condition that the distance between two silicon chips is no longer than 2mm. The larger the solar panel is, the higher the power is. Q: How to ascertain the actual power of lithium battery? A: Capacity of ?18mmx 65mm cylindrical Li cell: 3.7V 2200-2600mAh; Capacity of 6mm x 34mm x 50mm square Li cell: 3.7V 1200mAh. The larger the dimension is, the more capacitance material it contains. Thus the battery features larger capacity. In most cases, lithium cobalt is used as capacitance material. For cost cut, low-end batteries may use lithium manganese, which would lead to weaker standby capability of the cell. http://www.sunvalleyus.com/Solar-Charger/ You can find the exaggerated power mark in three cases. 20% higher than the actual power. You can only rely on the equipment measurement in this occasion. 1-5 times higher than the actual power. You can judge according to the battery dimension. Fuzzy unit to confuse the customer. To find out how much energy the battery really contains, you should consider both capacity unit (Ah) and energy unit (Wh). Wh= Ah*V Example: Battery A: 3.7V 20000mAh; Battery B: 11.1V 6666mAh; Battery C: 74Wh Which one do you think offers the highest energy? Maybe you would choose Battery A. Actually in the aspect of energy, the three batteries equate with each other. Here we highly recommend you our new coming solar charger. The unit is qualified for recharging your cell phone, digital camera, portable multimedia player, GPS, and other digital devices. Besides, you will like the practical design which allows for multiple placement options. You can clip it on your bag or attach it on the vehicle window glass, which means charging on the move. It is two-in-one solution for power supply and environment protection, right? For a clearer view of our solar charger’s advantages, you can refer to the chart below. Item Common low-power charger Solar charger from sunvalleyus Convenience Confined to a fixed location Multiple options: you can set it in fixed place, attach it on the travel bag, or mount it on the bracket for best angle to receive sunshine. Practicability Output current: 40mA. It costs more than 20 hours to fully charge the cell phone. Output current: 400mA. It costs 2-3 hours to fully charge the cell phone. Converting Efficiency Two conversions: solar energy to electrical power stored in the battery; from battery to your devices. 20% energy would be lost in these two conversions. Directly charge the device for minimum loss in conversion; Packed with mobile power supply as storage battery functionality Enjoy the green life. http://www.sunvalleyus.com/LCDPanel/
