Is It Worth Bringing a Solar Panel When Traveling by Bike?
As avid cyclists, we often find ourselves pondering the best ways to keep our devices charged during long-distance tours. The question arises: is carrying a solar panel a practical solution, or are there more efficient alternatives?
Understanding Portable Solar Panels
Portable solar panels have become a popular choice for outdoor enthusiasts seeking off-grid power solutions. These panels vary in size and capacity, typically ranging from 10W to 200W, and are designed to charge devices like smartphones, GPS units, and power banks. For instance, the BigBlue 28W panel, weighing approximately 1.5 pounds, can generate around 10Wh per hour under optimal sunlight conditions. (discovertrailcraft.com)
Assessing Daily Power Needs
Before deciding to bring a solar panel, it’s essential to evaluate your daily power consumption:
- Smartphone Charging: Approximately 44Wh for two full charges.
- GPS Device: Around 9Wh for a full charge.
- Power Bank (20,000mAh): Approximately 85Wh for a full charge.
These figures help determine whether a solar panel can meet your charging requirements during your journey.
Solar Panel vs. Power Bank with Fast Charger
Consider the following scenarios:
- Daily Access to Power Outlets: If you have regular access to electricity, a high-capacity power bank combined with a fast charger may suffice.
- Extended Off-Grid Periods: For longer stretches without access to power, a solar panel becomes more advantageous.
It’s crucial to select a power bank with a USB-C PD input of at least 65W and a compatible fast charger to ensure efficient charging.
Cost Comparison
- Solar Panel: A 28W portable solar panel like the BigBlue model is priced around $70 and weighs 1.5 pounds.
- Power Bank with Fast Charger: A 20,000mAh power bank with a 65W input and a 65W charger is approximately $65 and weighs about 1.3 pounds.
Both options are comparable in weight and cost, making the decision more about your specific needs and travel conditions.
Conclusion
The choice between a solar panel and a power bank with a fast charger depends on your travel plans and access to power sources. For cyclists embarking on extended off-grid tours, a solar panel offers a sustainable solution to keep devices charged. However, for shorter trips with regular access to electricity, a power bank combined with a fast charger may be more practical.
Ultimately, understanding your daily power requirements and the availability of charging options along your route will guide you to the most suitable choice for your cycling adventure.
