Foldable Solar Panel Xtorm SolarBooster 28W — Outdoor Solar Charger, IPX4, Universal Compatibility

Charging with the power of the sun

Xtorm SolarBooster 28W turns sunlight into reliable on-the-go power so you can extend every adventure. Whether hiking, camping or spending a day at the beach, this foldable solar panel keeps your devices charged without mains electricity — giving you more freedom and longer days outdoors.

High-efficiency monocrystalline cells — up to 24% yield

The SolarBooster uses four monocrystalline panels that deliver up to 24% efficiency per surface area, significantly outperforming older polycrystalline designs. These high-quality cells produce more energy in the same space, perform better in low light and tolerate a wide temperature range — meaning more usable solar power for your devices during real outdoor conditions.

Splash-resistant design and clear LCD readout

With an IPX4 rating, the SolarBooster stands up to light rain and splashes so you can keep charging in variable weather. The integrated LCD shows real-time output to help you maximize production and find the optimal panel angle — rotate the unit until the reading peaks for the best solar performance.

Integrated stand for optimal sun positioning

The built-in kickstand folds out to set the panel at the ideal angle and folds back into a compact package that fits easily in your backpack. For best results use the SolarBooster in direct sunlight on bright days; performance is reduced through glass or on cloudy days. The stand ensures you can always position the panel for maximum energy capture.

Store and use solar energy anytime

Pair the SolarBooster with an Xtorm power bank to store generated energy for later use. Capture solar power during the day and deliver a clean boost to your devices whenever you need it — truly unlimited charging while you’re outdoors.

Fast dual charging with USB-A and USB-C

Equipped with both USB-A and USB-C outputs, each capable of FastCharge up to 15W (5V/3A), the SolarBooster quickly powers a variety of small devices from smartphones and earbuds to tablets, action cameras and drones. You can also split power between both ports to charge two devices simultaneously.

Perfect for every outdoor adventure

Designed to deliver 28W of solar power, the Xtorm SolarBooster is ideal for staying connected while off-grid. Use it to recharge phones, GPS units, cameras or power banks and enjoy peace of mind on hikes, road trips and remote excursions — battery anxiety becomes a thing of the past.

Compact and travel-ready

The foldable SolarBooster packs small and travels light, making it a practical addition to any trip where sunlight is available. Keep your devices charged without mains power so you can capture photos, navigate and stay connected wherever the sun takes you.

Built-in safety for worry-free solar charging

Xtorm’s safety systems protect both the SolarBooster and connected devices from short-circuits, overheating and overcharging. Because the unit has no internal battery, there’s no risk of battery-related overheating — just safe, dependable solar energy when you need it.
