PRODUCT FEATURES

The unique design of solar cell charging box: The solar energy lithium battery boxes adapt the intelligent voltage regulation technology and dual voltage protection, over current protection and temperature protection technology, it will never harm your digital products and mobile phones.

Below are the functions and technologies that the common solar energy chargers in the market do not possess or not completely possess.       (*means high end or unique function)

*Real transformation efficiency: equal to or larger than 80%

*Phase lock voltages after confirmation

*Temperature compensation function, heat adjustment and overheat cut off function

*Smart protection function: over charge, over discharge, over load, reverse, short circuit, lightning proof

*3 step voltage adjust to comply with different digital products, especially fit for DV products

· Smart charging function: Step charge, prolong battery work life

- PWM Pulse to keep constant voltage to the charging devices                                                                                                 

· LED indicate built in battery electric energy that makes the end users easy to identify

-The batteries can store electricity not only from sunshine, but also from USB or DC alternating current.

·The photo electricity transformation rate can reach 15.0%. Compared with other common solar energy chargers in the market which are with the transformation rate of 9% ~12%, this is a very important breakthrough.

-The lithium batteries inside the solar energy movable electrical sources are made by a professional lithium polymer battery supplier. The lithium polymer has superior safety function that even under short circuit condition, if the charging box does not function, the lithium polymer battery cells wont explode that prevents any harm to the users.

· Cost performance: Our products have a certain price advantage, and they are more practical. Meanwhile our products have the advantages of other like products.

· This product can not only supply emergency charge through solar energy, but also can charge through computers USB connector, and DC (220V/110V). It will be customers choice.

· Solar panel panes are made from recyclable PET material.
