Most people know that we can generate sustainable power for our indoor devices with solar panels on our roofs. But did you know that you can also harness the power of the sun while on the go?
A Solar Power Bank, is a portable charger with a built-in solar panel. In this blog, we’ll explain how a Solar Power Bank works and what the best solar Power Banks are right now!
How does a Solar Power Bank work?
A Solar Power Bank works just like a regular Power Bank, but with one clever addition: it has a built-in solar panel. This panel converts sunlight into electricity, which is used to charge the internal battery of the Power Bank. Of course, it’s also possible to recharge a Solar Power Bank the traditional way, via mains power.
What to look for when choosing a Solar Power Bank?
When choosing a Solar Power Bank, keep these factors in mind:
• Solar panel size: The larger the panel (or the more panels), the faster you can recharge via the sun. Keep in mind that Solar Power Banks typically have a small integrated solar panel, which makes solar charging slower than charging via mains power.
• Battery capacity: Choose a capacity that suits your usage. A Power Bank with 10,000 mAh is ideal for everyday use, while 20,000 mAh or more is better for longer trips.
• Extra features: Consider built-in flashlights, solar indicators, or rugged casings for outdoor use.
• External influences: The charging speed of a solar panel is influenced by several factors, such as cloud cover, the position of the panel, and the season. In this blog, we’ll explain exactly what you need to consider when charging with solar power.
Top 3 Xtorm Solar Power Banks of 2025
1. Rugged Solar Power Bank 10,000 mAh
The Rugged Solar Power Bank 10,000 mAh is Xtorm’s best-selling Solar Power Bank, and for good reason. This Power Bank features three built-in solar panels that fold out easily, maximizing the surface area for solar charging. In optimal conditions, you can charge your phone up to 30% in 2 hours. It’s ideal for hikes, beach days, or other moments when you need that extra boost. Thanks to the integrated kickstand, you can easily position the Power Bank to catch as much sunlight as possible.
2. Go2 Power Bank Solar Panel and Flashlight 10,000 mAh
The Go2 Power Bank 10,000 mAh is a versatile choice, featuring a built-in solar panel, a large LED light, and a carabiner hook to attach it to your bag or tent. The solar panel is smaller, making it better suited as a backup for emergency charging. The solar-strength indicators show how much sunlight is being converted into power. With a 10,000 mAh battery, you can fully charge your smartphone about twice. This Power Bank is perfect for camping, festivals, or adventurous trips.
3. Rugged Power Bank 20,000 mAh + 28W Portable Solar Panel
If you want to get a bit more out of the sun while still keeping things portable, our solar bundle with the Rugged Power Bank 20,000 mAh and the 28W Solar Panel is the best option. With the Power Bank, you can charge your device up to 5 times. If the Power Bank runs out, simply connect the portable solar panel to the Power Bank using a USB-C cable and place it in the sun. In optimal weather conditions, the Power Bank will be fully charged in 8 hours. You can also directly connect your phone or other small devices to the solar panel itself for charging via solar energy.
Can I charge my phone with solar power?
You can charge your phone using solar energy, but here's how it works with a Solar Powerbank: you charge the Power Bank using solar energy, then use the Power Bank to charge your phone. If you want to charge your phone directly with solar power, we recommend our Solar Boosters. These portable solar panels have a USB-C port, allowing you to connect small devices directly for solar charging. Our 14W Solar Booster can charge an average phone in 2.5 hours in optimal conditions. With the 28W Solar Booster, this will take about 2 hours.
We hope that after reading this blog, you know exactly which Solar Power Bank suits you best. If you have any questions about solar charging, feel free to contact our customer service at info@xtorm.eu.
