The  backpack  products characteristic of solar energy:

    First, the product is novel and practical, solve your worry.

    1. The newest integrated design, charge the solar energy, hold theelectricity, the voltage outputs the function and formates an organic whole. And fix on bag, easy to use.

    2. Until you in field work, travel, go on business or meet, lose electrical power, make Mobile and digital product of you keep the working state whenever and wherever possible.

    Second, powerful, the high efficiency is charged.

    1. Adopt CPU control technology, ultralow consumption, fully utilizes solar energy, offer and charge the electric current the most largely.

    2. It is stiff to adopt 1.35W solar energy, the biggest output 240mA   3. Polymer of built-in 1800mAh high capacity lithium battery. Offer 500mA to export electric current 4. Put and charge the interface fast inside, under not having a illumination condition for a long time, can charge fast for this product through the outside charging set (such as the computer USB interface or any mobile phone of adapters). 5.5V and 4.3V voltage switches over the function, USB exports the interface, the commonability is strong. Suitable for different voltages such as mobile phone, MP3, MP4, GPS and digital camera,etc. to require. The special circuit is designed, charge the function with large capacity mobile phones such as the compatible IPHONE cell-phone,etc..  High efficiency charge, charge 60 minute, can obtain conversation time for less than 100-150 minute.

   Third, energy-conserving environmental protection.

      1.Real green energy-conserving products.
