Whether you’re planning a road trip, sailing adventure, beach getaway, or camping trip, keeping electronics charged up in remote areas can be challenging. The best solution is taking with a portable solar panel and a portable solar generator, there are many options out there when it comes to portable solar panels, which may be a portable solar panel for backpacking, portable solar panels for RV, or solar panels for camping trailers. And there are several type portable solar panels on the market to choose from. Panels only, either rigid or semi-flexible, panels with integrated energy storage cells, panels with separate batteries.

Main factors to consider when picking portable solar panel

1. Surface area.

The larger the portable solar panel, the more sunlight it collects and the faster it is converted into electricity that is stored in the battery. A smaller portable solar panel, while easier to pack, but takes longer to charge the battery. Large-area portable solar panels are also best for use in cloud cover or low-level, low-intensity light in winter, or when logistical constraints allow you to leave it exposed to the sun for more time. Depending on surface area and lighting conditions, the same battery can take anywhere from 4 to 16 hours to charge in sunlight.

2. Output capability.

portable solar panels are rated in watts. The higher the number, the more electricity is generated during a certain period of time.

3. Semi-flexible or rigid panels.

Semi-flexible portable solar panels can be folded or rolled up for easy transport and open up to provide a larger surface area than many rigid panels. Also consider how the solar panel is attached so you can securely attach it to your backpack, bike, rowboat or tent.

4. Power storage (battery pack)

Portable solar panels are best used to charge batteries or an outdoor power station, not directly to charge electronic devices. As a power source, the current generated by these solar panels directly flows into the electronic equipment without any current regulation circuit, which is likely to cause damage to the electronic devices.

Selection Considerations for Output Connectors and Adapters

If you buy a portable solar panel with a built-in battery — whether integrated or standalone — any necessary connectors between the panel and the battery will be included.

If you buy the solar panel and battery separately, pay attention to its output connector, and whether it’s suitable for charging your device directly or connecting to a separate battery pack. Your options may include a USB (standard, mini, micro), a connector or a DC output with voltage control.


Be sure to choose a portable solar panel that is easy to carry when you travel outside, otherwise it will become a burden. The complete review of ChargingGeek has list the best portable solar panels on the market, you can easily pick the one you needs. When traveling outdoors, unfold the solar panel, hang it on your backpack or tent, and recharge while walking without any delay. You can directly charge the mobile phone, which can be fully charged in about 2 hours; you can also charge the power bank, which basically guarantees that the power bank is full at any time. It is recommended to use the solar panel and a large-capacity power station when traveling outdoors. If you drive and camp by yourself, you can bring an outdoor power station with a 100W portable solar panel. With a weight of 3.4KG, girls can also lift it. Outdoor power station can solve the problem of mobile phone charging, tablet charging, drone charging, outdoor lighting, car refrigerator, and rice cooker. The solar panel has played a very good supplementary role, avoiding the helplessness caused by excessive use. If the 100W portable solar panel is fully charged with the 300W outdoor power station, it will take about 7 hours, which generally meets our outdoor power needs.
