A solar power bank is particularly interesting when you want extra charging options on the go and don't always have a wall outlet nearby. For camping, traveling, and emergency kits, solar energy can be a useful addition, but the size and quality of the solar panel determine how useful it is in practice.
In this comparison, we set four solar power banks side-by-side based on capacity, charging power, and usage situation. This way, you don't simply choose the largest battery, but the model that fits your usage.
Which solar power bank is right for you?
- Compact and all-round: 20,000 mAh for daily use, camping, and emergency supplies.
- Longer trips: 32,000 mAh with four foldable solar panels.
- Lots of reserve: 50,000 mAh for longer periods between charging moments.
- Laptop and heavier equipment: ALLPOWERS PB100 with 100W USB-C PD and external solar panel.
What should you look for in a solar power bank?
You charge a regular power bank via a wall outlet beforehand. With a solar power bank, a solar panel can provide extra energy on the go. View the built-in panel primarily as an addition: small panels charge significantly slower than a standard mains charger or a larger external solar panel.
Capacity
Capacity is usually stated in mAh. A higher number means more stored energy, but generally also more size and weight. Therefore, compare not just the capacity, but also what you actually want to charge.
Charging power
For modern smartphones and tablets, fast charging is convenient. For a laptop, you usually need a powerful USB-C PD output. Always check what your device supports.
Solar panel
A larger panel surface can generate more energy under favorable conditions. Foldable or external panels are therefore more interesting if solar energy is truly an important part of your charging strategy.
1. Alfa Survival solar power bank 20,000 mAh
Best choice for compact all-round use.
The Alfa Survival 20,000 mAh solar power bank is aimed at daily use, camping, and emergency kits. Its compact size makes it easier to carry than models with larger batteries and foldable panels.
This version is particularly suitable if you are looking for a power bank for phones and small USB devices and want solar energy as an extra option.
2. Solar power bank 32,000 mAh with 22.5W fast charging
Interesting for longer trips.
This 32,000 mAh solar power bank combines 22.5W fast charging, 15W wireless charging, and four foldable solar panels. The larger solar panel surface makes it more practical when you actually want to recharge with sunlight on the go.
3. Solar power bank 50,000 mAh with fast charge
For those who primarily want a large energy reserve.
The 50,000 mAh solar power bank focuses on battery capacity and 22.5W fast charging. Such a larger battery is especially relevant when there are long periods between normal charging moments.
4. ALLPOWERS PB100 100W with 21W solar panel
For laptops and more powerful USB-C devices.
The ALLPOWERS PB100 laptop power bank has a capacity of 24,000 mAh, a 100W USB-C PD output, and is combined with an external 21W solar panel. This model is aimed at users who want to charge a laptop, tablet, or camera in addition to a phone.
Comparing solar power banks
| Model | Capacity | Solar solution | Charging power | Best suited for |
|---|---|---|---|---|
| Alfa Survival solar power bank | 20,000 mAh | Fixed panel | Fast charging | Daily, camping, and emergency kits |
| Foldable solar power bank | 32,000 mAh | 4 foldable panels | 22.5W | Longer trips and camping |
| High capacity solar power bank | 50,000 mAh | Fixed panel | 22.5W | Large energy reserve |
| ALLPOWERS PB100 | 24,000 mAh | 21W external panel | 100W PD | Laptop and heavier USB-C devices |
Important: do not choose a solar power bank solely based on the highest mAh number. Look at charging power, connections, panel surface, and how much weight you want to carry.
Which solar power bank is the best choice?
There is no single model that is the best solar power bank for everyone. For a compact emergency supply or day trip, 20,000 mAh is often more logical than a much larger model. For longer outdoor trips, a foldable panel can add more value. If you want to charge a laptop, the available USB-C PD power is the deciding factor.

Frequently asked questions about solar power banks
Can a solar power bank charge completely via the sun?
In principle, yes, but it often takes a long time with a small built-in solar panel. A larger foldable or external panel is more suitable if solar energy is to be an important charging source.
How much mAh do I need?
That depends on your devices and how long you want to be without a wall outlet. For phones, a medium-sized power bank is often sufficient; for multiple devices or longer trips, extra capacity is useful.
Can I charge a laptop with a solar power bank?
Only if the power bank offers sufficient output power and the correct connection, usually USB-C Power Delivery. Check the required wattage of your laptop.
Conclusion
The best solar power bank is the model that aligns with your usage. Therefore, compare capacity, charging power, and solar panel in conjunction. This will give you a usable energy solution for camping, traveling, or an emergency situation without choosing one that is unnecessarily large or heavy.
