Lumos - The backpack as a charger for your smartphone

On multi-day tours, you don't always have access to the power grid. Empty batteries on cell phones and GPS devices are not exactly helpful. This is exactly where Lumos comes in, designing mountain bike backpacks with sewn-in solar panels that you can use to charge your devices while riding.

In our case, the bike backpack "Thrill Seeker" is the interesting product. It has 12 liters of storage space and measures 23 x 12 x 42 centimeters, with a weight of 800 grams. Inside it has an extra compartment for a 3-liter hydration bladder, in the main compartment for a rain jacket, food and has compartments for a pump and spare tubes. Another extra compartment on the underside is intended for the minitool. A clip-on warning light can also be attached there.

Small pockets for keys and small change are located on both sides of the hip belt as well as a signal whistle integrated into the click fastener of the chest strap for emergencies. The shoulder sections of the "Thrill Seeker" contain perforated foam. This ensures better air circulation, which should reduce sweating in these areas. The Lumos backpack is also said to be characterized by excellent stability on the back.

In general, the Lumos bags each have a lightweight solar panel sewn onto the outer surfaces. These feed the 4000 mAh battery inside the bag. This energy can be used afterwards or directly to supply GPS devices, lamp batteries, cell phones and other gadgets with power via a USB cable. The battery is also replaceable. Each bag has a universal USB output.

The special thing about the Lumos bags is that they can generate power even in poor lighting conditions thanks to trickle charging.
Exposing the backpack to sunlight for an hour results in a 5- 10 percent battery charge for a smartphone. According to Lumos, two hours of exposure results in approximately one hour of battery life.

These bags have already undergone several test stages in Germany and are CE and ROHS certified.
