How many times do you find the term "green technology" appears repeatedly in the news? Do you have experience in technology green yourself? How can we apply in everyday life? Here's a simple solution: solar charger. The high performance of solar panel power coverts solar power and can recharge their mobile phones in 3-4 hours. It also applies to MP3 player, digital camera and other digital items that are popular on trips. Take this gadget and never worry about running out of juice.
Here is FAQ on solar charger.
Q: How to check the power actual solar panel?
A: You can judge on the basis of the surface and the packing density of solar panels. Usually, a panel of 10 cm x 10 cm can be achieved 1.5 W power in the condition that the distance between two silicon chips is no longer than 2 mm. The larger the solar panel, the greater the power is.
Q: How check the real power of the lithium battery?
A: Capacity? 18mmx 65mm cylindrical cell Li: 3.7V 2200-2600mAh, capacity 6mm x 34mm x 50mm square cell Li: 3.7V 1200mAh. The greater the size, material containing more capacity. Thus, the battery has more capacity. In most cases, the lithium cobalt is used as material capacitance. To reduce costs, low-end batteries can use lithium manganese, leading to capacity Waiting weaker Cell. Http: / / www.sunvalleyus.com/Solar-Charger/
You can find the brand of exaggerated power in three cases.
- 20% higher than the actual power. You can only rely on the metering equipment on this occasion.
- 1-5 times greater than the actual power. You can judge according to the size of the battery.
- Each approach to confuse the client. To see how much battery power it actually contains, must consider both the unit of capacity (Ah) and the unit of energy (Wh). Wh = V * Ah!
Example:
A battery: 3.7V 20000mAh;
B Battery: 11.1V 6666mAh;
Battery C: 74Wh
What do you think offers the highest energy? Maybe they choose the battery A. Indeed, in the aspect of energy, the three batteries to match each other.
