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.
Do a lot of biking or hiking and want to make sure all your electronic devices stay charged? You are already out in the sun with a backpack, might as well use all that free energy beaming down on your pack. Let`s meet our new solar gadget-- SunPack, a backpack designed to keep your devices charged everywhere. You can use SunPack to run electrical devices such as tablets , mobile phones, smart watch, GPS, and other USB gadgets.
SunPack can be for anybody, for outdoor activities or daily business use. SunPack is a backpack with added benefits: a removable solar panel which can provide power source when you need it most. It may save people's life some day when they are in the wild and lost all the power. If you have SunPack, you can charge your phone and at least to send help signal out as long as the sun is out.
Never worry about running out of phone battery when you are taking pictures for cute kitty ! :)
We are Flextech Solar Gadgets team, specialized in different types of solar applications. This is our 4th Kickstarter campaign of solar gadgets, we have successfully delivered 2206 pieces of solar products to our crowdfunding backers from 68 countries over the world.
'' I absolutely love this portable solar charger! You kept your promise and produced a superior product...I don't know of any system currently available that even comes close to this solar charger. Thank you for keeping your promise to me and all the other people who took a risk and pledges your product. I wish you all the best success for this and all the other products you create. Thank you so much, I KNOW that one day, you will receive a post where this saved the life of someone stranded somewhere. YOU GUYS ROCK!!!!'' --- Review from previous campaign.
Backpack details` introduction by Andrew
Advanced solar technology with ETFE film coating+ integrated laminating + dimple surface
1) Dimple surface does not reflect the light , captures more sunlight and increases 5% solar absorption rate. It offers excellent efficiency in terms of light to electricity conversion.
2) Non-adhesive surface properties. The dirt, dust and many other pollutants are less likely to contaminate the surface of panels. When this kind of contamination occurs, a damp cloth will typically remove these particles to avoid blocking sunlight from reaching the solar panel. Also it`s stain-resistant .
3) ETFE film coating on the solar panel. A key benefit of ETFE (Ethylene Tetrafluoroethylene) coated solar panels is that they are super durable & lightweight. And the ETFE coating provides a thin 2mm layer of protection and UV resistant. It`s durable with long lifespan .
The below two projects are the representatives of applications of ETFE (Ethylene Tetra Fluoro Ethylene) film material.
This feature is the same as Powerleaf, check below to watch the test videos.
Features integrated 3500mAh battery in the backside of 5.3W solar panel .
Why is an integrated battery necessary for the backpack solar charger?
Based on the past test experience and clients` feedbacks, the solar charging performance will be influenced by the angle of the solar panel. When on the move , the angle is always changing, so we design charging the battery and using the battery as a buffer between the solar panel and the smart phones.
Mobile games draining your battery? Or need to make that important call and your mobile phone is almost dead? Fear not: SunPack’s external USB port is all you need. It`s external USB charger port with built-in charging cable offers a more convenient and easier way to charge your phone, tablet and other electronic devices.
With SunPack on your back, you will never again have to worry about driving a bike or ridding a cycle during night. Reflective panels make you an easy target to spot from a distance.
The SunPack RFID-shielded pocket will keep your personal data safe and secure. RFID Technique: Radio Frequency Identification technology, through radio signals to identify specific targets and to read and copy electronic data. Most Credit Cards, Debit Cards, ID Cards are set-in the RFID chip, the RFID reader can easily read the cards information within 10 feet (about 3m) without touching them. This pocket of SunPack is designed to protect your cards information from stealing with blocking material of RFID shielding technology.
Equipping with password lock to help prevent theft and keep your wallet and other items inside secure while travelling. For example, there is no need to worry about the zipper pockets are opened when you line up. At the same time, never worry about that the fixed lock will be lost, it's convenient and safe for you.
More compartments, more storage, better organization -- you can have it all. The SunPack solar backpack has compartments for all your office essentials from stationery pens, notebooks and external hard drives, to documents, your passport, keys, USB drives, cables and laptop chargers.
Open every door easily and don`t lose your keys at inconvenient times !
1. PLUG 6.1W solar panel -- For solar charger starters to try , DIY solar gadgets, emergency preparation.
This is our 4th Kickstarter campaign of solar gadget, 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 SunPack 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 SunPack 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!
