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.
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.
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
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.
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.

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 press partners
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.
