A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
Hit the goal & Giveaways (☀Update )
If Powerleaf+ campaign hit the goal $10000, every backers` rewards will be upgraded with FREEpowerbank !!
These days, when so many of us have portable devices, and we move around so much, having a portable solar charger isn’t just nice, it’s a necessity. Powerleaf+ is an upgraded version of previous Powerleaf solar charger. You can use this solar charger to run electrical devices such as tablets ,mobile phones, your GPS, other 5V gadgets or charge your 12V batteries directly. It`s essential for outdoor activities, such as hiking, camping, and outdoors military training. So that even in absence of power support, there is electricity as long as there are sunshine and solar charger.
Where can you use Powerleaf+ ?
The Powerleaf+ solar charger is useful in many different scenarios. The solar cells can be collecting sunlight while you are on the move or staying still. Consider using the solar charger for any of these activities and more~
Away from home
What is different of Powerleaf+ ?
Adjustable integrated stand to get optimal solar angle
When the angle between sunlight and solar panle is vertical, the power is maximum. When the angle between sunlight and solar panel is inclined, the power are diminished. When the angle between sunlight and solar panel is horizontal or negative, the power is zero
This current level indicator offers 3 colors of LED that light up progressively as the current increases:
1. NOT light : less than 350mAh output
2. Purple : Greater than 350mAh output
3. Blue: Greater than 550mAh output
4. Green : Greater than 800mAh output
With the help of LEDs, you will clearly know how many current the solar panel generates , also you can adjust the stand to get the best angle as well as choose the most suitable devices to charge.
1. USB port 5v , to charge cell phones, power banks, digital cameras, MP3/MP4s, Kindle’s, portable DVD players, Bluetooth headsets, PDAs, and, a host of any USB- chargerd devices.
2. DC5521 14.8V, to charge 12V battery, jump starter and external battery packs for laptop
3. We will provide accessary: DC5521 male to male cable, DC5521 male to alligator clips cable with voltage stabilizing function, USB male to android, ios, type C 3 connectors charging cable.
ETFE film coating+ integrated laminating+ dimple technology.
1. Capture more sunlight and increase the solar absorption rate by 5%
2. Non-adhesive surface , stain-resistant ,easily get cleaned by rain or damp cloth
3. Lightweight, UV resistant, durable, long lifespan
This feature is the same as Powerleaf, check below to know more
Compared with our first version of phototype, we cut off all the unnecessary parts in the second version to make product design more compact and lightweight , it `ll be more suitable for backpackers, hikers.
Auto Restart Technology ---ensure stable charging performance.
When shadow leaves, it will automatically restart in few 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.
Large capacity zipper bag
There is a zipper bag at the back of the charger to hold your phone, cable, carabiner and any other small accessories safely and organize them well.
Why do we start Powerleaf+ project ?
To perfect the previous version of Powerleaf solar charger ,make it faster charging, more complete function
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 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
This is our 4th Kickstarter campaign of solar charger , through previous campaigns, we understand that backers bear risk with us and make a pledge, we know how hard to successfully handle with every part- including product design, manufacture , package, delivery, service.....even every piece of material we choose... Now Powerleaf+ product design is in the final stage, our current prototype is with function, but we need to make new molds and final moldfication, such as imporove the material quality of the stand and do more tests of the charging indicator, also bring Powerleaf+ to massive production.
Some ricks and challenges are:
1. Shipping date: We have built in extra time for the manufacturing process and are confident we will ship by the projected dates, but there is always a chance that things will take longer than planned.
2. Product changes: Slight changes may be made based on more product testing and kickstarter community feedback. We'll only make changes that enhance the product experience.
3. Small components unexpected shortage can happen. In that case, we will inform you and do our best to solve the problem.
Please also feel free to let us know your concerns, we look forward to hearing from the Kickstarter community.Thank you for your support!
