Quality control

In contrast to conventional solar panels, the SUNPOWER cells installed at SUNNYBAG have a significantly higher efficiency - namely 22.4%. To guarantee this, we test each panel for performance before shipping. The test certificate is enclosed with every SUNNYBAG and shows not only the achieved performance but also the day and time of the test. This way you can be sure that your SUNNYBAG delivers what it promises and that your devices are reliably supplied with renewable energy.

Optionally with POWERBANK

Our powerbanks are specially designed for charging with solar energy. They are the perfect temporary storage for the clean solar energy. The optimized power management (OPF technology) allows simultaneous charging and discharging. The powerbank stores the fluctuating solar energy efficiently and delivers it evenly to your smartphone. This is the most efficient way to use your SUNNYBAG.

Charging current display

The Power Indication Color at the USB output shows you how much power is currently being generated and how long the charging process for a smartphone takes under these conditions. Simply plug in your smartphone and read the charging time from the LED lights.


We are a young and dynamic company from Austria that develops and distributes portable solar chargers. These charge your electronic devices on the go environmentally friendly with solar energy. Thus, each SUNNYBAG inspires to use renewable energy in everyday life.

Sustainably packed and delivered

We pack our solar panels and powerbanks plastic-free in recyclable boxes. We ship your packages Co2-neutral with the Austrian Post.

Extended warranty

The longer a solar panel is used, the more renewable energy it generates. Therefore, we offer 5 years full warranty if you register your SUNNYBAG.
