Charging with the power of the sun

Exploring with unlimited energy, that sounds like a dream for every adventurer. Whether it is a big or a small adventure, Xtorm Solar Charging makes it possible. By charging your devices with the power of the sun, even during your hikes or during camping, you can longer enjoy your adventures, beach day or picnic.

A 24% high return

The SolarBooster's four panels are made of monocrystalline solar cells. These more expensive, but higher-quality solar panels, are made of a single piece. As a result, the yield per surface area is maximum 24%, compared to only 17% for Old Gen polycrystalline panels.

Also, a monocrystalline panel works well in lower sunlight and at both lower and extremely high temperatures. As a result, the SolarBooster’s panels provide more energy to your outdoor-adventure than other solar panels.

More solar energy to charge your devices!

Resistant to splashes and clear display

Rated IPX4, the SolarBooster can withstand small raindrops from all directions for 5 minutes and will not even be damaged by a light rain shower.

The LCD screen gives you an accurate figure of the output the SolarBooster is providing to your devices. Besides that, the screen also helps you to place the solar panels in the optimal position. By rotating the SolarBooster, the number on the screen increases when it is faced in the best direction. A great tool to make the most of the sun’s power!

Place it on the bright side

The integrated stand ensures that the SolarBooster can
be easily placed and also easily gets folded into a compact package again. The folded package fits in your backpack and can be taken anywhere.

You get the most energy from the SolarBooster on a
sunny, bright day. When it is cloudy, the yield is much lower. It is also important to make use of direct sunlight. Behind glass or, for example, the windscreen of a car, the SolarBooster works much less efficiently. You need to get out there and enjoy new adventures in the outdoors!

Always optimal sun-angle, because of integrated kickstand.

Unlimited energy

Combine the Storm Solar Booster with an Xtorm Power Bank to Store the generated energy for later. Give your devices a pure energy-boost with the power of the sun.

Unlimited charging your devices.

Sunny way of dual charging

With both a USB-A and a USB-C connection on the SolarBooster, you can re-energise different small mobile devices, wherever you are. It is also possible to split the SolarBooster's power between the connections and charge two devices at the same time!

Great for Home or on the Go

Pros: compact, foldable and easily portable, snaps snugly shut, not too heavy, sturdy material, 2 connections (USB-A & USB-C), holes for d-rings or other fasteners, charges fast, kickstand.

Con: only 1 kickstand, that is off-center, so one side of the solar panel sags under its own weight (see photos). I can see this causing problems in the future.

Conclusion: A great product for the porch, campsite, or wherever you may find yourself outside.
