FlexSolar has been a pioneer in solar chargers for years .Now we launch the improved USB solar charger--Powerleaf  on Kickstarter.

Powerleaf is a portable solar charger for camping, travelling, hiking and emergency preparation. It can charge all your USB devices including smart phones, tablets, power banks, and other gadgets. Or you can combine it with other products, such as bags, golf cart, boat, tents.

 

 

 Below are some application scenarios of FlexSolar® Powerleaf

 Powerleaf can supply power for you in different environments,even in the desert and snow.

 

It can become a Plug and Play Solar charging system, the USB cooling fan shown here was charged by Powerleaf .

  •  Powerleaf also pays much attention to detail. As you can see the copper ring is sturdy and could be hung from a tree or support stand.Round corners prevent any chances of scratching the hand.

 

  • Auto Restart Technology ---ensure stable charging performance. 

When shadow shelters the solar panel, the charger will stop working. For traditional solar charger products , people have to unplug the USB cable and replug it, then it comes back to life. But Powerleaf solves this problem with auto restart function . When shadow leaves, don`t worry, it will automatically restart in 5 seconds and come back to charging function.

When sunlight gets stronger in the process of charging a cellphone, Powerleaf will disconnect and auto restart at a higher current to charge the cellphone

  • Maximum Power Point Tracking (MPPT) function is a technique used with photovoltaic (PV) solar systems to maximize power output.The voltage regulator inside junction box has unique MPPT function. It increase the output power by 30% by controlling the charger`s output voltage at its maximum power point
  • Water proof

  •  Excellent materials

 The ETFE (Ethylene Tetra Fluoro Ethylene) film has excellent ability of light transmittance and aging resistance. It not only  improve the output power of  solar panel but also can extend lifespan.

The below two projects  are the representatives of applications of ETFE material.

 

Powerleaf mainly includes solar panel and junction box , It uses solar cell with high efficiency up to 23%. The volatage regulartor inside junction box is suitable for smart phones like iPhone,Samsung , Blackberry, HTC, power banks, and other electronic devices.

 

 It`s  stable 5V output voltage, without any harm to electronic devices or human body.And Powerleaf is compliant with CE and RoHS certifications, pass all the tests, ensuring your safety and health.

Moreover, Powerleaf has passed the Double 85 Test, that means it was put into the equipment with environment temperature 85 ℃, relative humidity 85%, tested for 1000 hours, the apperance and electrical performance of Powerleaf  are still good without any change.

 

 

 How to use Powerleaf?

 Why do we start Powerleaf project ?

  • To bring you conveniency for outdoor activities. With Powerleaf you don’t have to worry about running out of power when you are in the outdoor.
  • To share technology fruits with you . All our competitors are still adopting the old sewing technology that needs more processes and it`s not waterproof. FlexSolar is leading the world on our unique lamination method, and hope more people can benefit from this advanced technology.
  • To lower purchasing cost and make it cost-effective. Materials including solar cells and others components are cheaper when purchased in bulk .
  • To do a little bit for green environment. Using renewable energy like solar power is clearly a way to diminish our dependency to fossil fuels, and is a good way to mitigate global warming by lowering the emission of greenhouse gases.

Risks and challenges

We understand there might be unforeseen issues even for the best laid plan, however, samples of Powerleaf have been made, tested, and put into some real life situations to use. They perform very well.

Our biggest challenge will just be international logistics. we already have collaborated with the logistics company before to minimise the risks, will try our best to get these panels shipped to our backers immediately.

Please also feel free to let us know your concerns, we look forward to hearing from the Kickstarter community.
