What is a prototype?

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.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Same size, twice the performance

SunnyBAG introduces the new and improved SunnyBAG LEAF+, the world's first hybrid solar system that combines the advantages of two world leading cell technologies in one product.

 
Product features

SunnyBAG LEAF+ is "the lightest, flexible outdoor solar system in the world" for outdoor lovers and everybody who wants to use an independent electric power supply all around the world. Whatever you are going to do - hiking, climbing, tours, cycling, golfing, camping or at festivals - the SunnyBAG LEAF+ offers a flexible solar panel that weighs less than 200 grams.

The unique Triple-Junction technology utilizes thin-film solar cells made from amorphous silicon, which allows the module to produce power even when partially shaded. Each cell absorbs the blue, green and red light of the sun through the three layers of the cell. Thus the Triple-Junction solar cells convert a wider spectrum of light into electricity than conventional cells. Together with the SUNPOWER® panel technology, this hybrid solar system achieves an increased power output of 6,2 watts.

The SunnyBAG LEAF+ is virtually indestructible due to the robust material. It has a scratch and impact resistant surface and holds even in cold weather, rain, snow and wind. At the same time, it is highly flexible and can easily be attached with its integrated hooks on backpacks, bags, tents etc.

Weight and dimensions

LEAF+ For a better understanding how lightweight and small the SunnyBAG LEAF+ is, we have this scratch with the most important information.

So the size is a little bit bigger than a DIN-A4 sheet and it is only a few millimeters thin. The LEAF+ itself weights 198 grams and the PowerStick (= power bank) is another 120 grams.

Compatible devices

The SunnyBAG LEAF+ is designed to charge any mobile device that can be charged via USB port. Electronic mobile devices such as smartphones, phablets, tablets (e.g. iPad), digital cameras, smaller video cameras, mobile gaming consoles, GPS und satellite devices, portable music players (e.g. iPod, mp3 and mp4 players) and many more additional devices can be operated via the ecologically friendly solar energy.

Additional connectors at 35k funding

Your feedback was very clear. The new SunnyBAG LEAF+ needs a USB-C connector to be equipped for the future. Therefore, we discussed with our controlling in order to offer you this stretch goal. With a funding of € 35,000 every backer gets a large connector update: 

  • USB cable with micro USB connector
  • Lightning connector for Apple iPhone and iPad
  • 30-pin connector for older Apple devices
  • USB-C connector based on your feedback

 
Charging times

When used in direct sunlight, the SunnyBAG LEAF+ is most efficient in storing energy (using the included SunnyBAG PowerStick) and charging mobile devices via the USB converter directly because of its maximum output design. But even in cloudy weather conditions the LEAF+ still works effectively due to the unique Triple-Junction technology that allows a very good low light efficiency.

Our Pledges

Stretch goals

Project timeline - delivery in December 2016 


10 months of development

For 24 months the SunnyBAG LEAF, the predecessor of the new LEAF+ model, has been used and tested all around the world - from the North Pole to the desert in Africa - and the collected results of the study have led to substantial improvements of the product. This cheered us on to develop the follow-up product within ten months. While its size remains unchanged, the next generation SunnyBAG LEAF+ offers twice the power and makes use of enhanced hybrid solar technology.

 
Prototype testing

Press

Futurezone - "SunnyBAG has great technology and quality in every single detail. It's fun to charge your device by using solar energy outdoors!"

Gizmodo - "SunnyBAG solar gadgets are not only cool, but also really practical."
 

Comments on the SunnyBAG LEAF (previous version)

Austrian Alpine Club - "SunnyBAG LEAF is a useful, light and good implemented opportunity for people who need electrical power supply on the way."

Netzwelt.de - "SunnyBAG LEAF scores in our short test particularly due to the robust making and the little weight. For this reason, it offers high flexibility especially for outdoor activities."

Bergauf Magazin - "We saw many different things in this sector, but such a good solution is uncommon and now finally available."

Our story

SunnyBAG was launched by Stefan Ponsold in Graz, Austria with the idea of creating solar bags for Doctors Without Borders with sophisticated design which had never been launched before. Since 2010 we have developed and produced solar bags and backpacks to charge smartphones, tablets and wearables on the go in an environmentally friendly way. In this field we're the #1 in Europe with more than 600 points of sale and great cooperation projects. We have also founded the SunnyBAG Inc. based in Silicon Valley.

Risks and challenges

We did and will do our best to successfully deliver what we've promised to our SunnyBAG backers. Component delays and unexpected shortage can happen. In that case, we will inform you and do our best to solve the problem.

What is more, we want to inform you that customs and taxes are not included in the price. Depending to your home country you might have to fill in a customs declaration and pay customs and taxes before you get your SunnyBAG LEAF+. We can't cover any compensation claims that arise due to your personal effort while handling these issue. Thank you for your understanding.

We will support you in every matter. Please contact us if you have any queries.

Your SunnyBAG Team.
