This setup is perfect for charging smaller electronics like smartphones, GPS units, and cameras on the go.
Solar Backpacks with Integrated Solar Panels
These backpacks feature built-in solar panels that collect solar energy while you walk or hike. The solar power is stored in an internal battery, allowing you to charge devices like phones or tablets during your journey. Solar backpacks are a great option for long-term trips where you need continuous power on the move without the need to carry extra charging devices. They are particularly useful for people who want an all-in-one solution for energy storage and portability.
Panel-Only Solar Chargers
These chargers consist of solar panels without built-in batteries. They require an external power bank or power station to store the collected energy. The solar panels can be either rigid or foldable, depending on the model. Panel-only chargers tend to be larger and heavier, making them better suited for powering small appliances or for emergency preparedness. While they may not be as portable as the foldable solar chargers, they are more powerful and capable of handling higher energy demands.
How to Choose a Solar Battery Charger for Backpacking?
When selecting a solar battery charger for backpacking, there are several factors to consider to ensure you get the most reliable and efficient product. With a growing number of solar charger brands on the market, it can be overwhelming to make the right choice. Here are the key factors to help you choose the best solar charger for your outdoor adventures:
- Output Capacity
The output capacity of a solar charger is measured in watts (W), which indicates how much energy the panel can generate. A higher wattage means the solar charger can produce more electricity, allowing you to charge your devices faster. When selecting a charger, look for one that provides a good balance between output capacity and price. A charger with higher output will be more efficient, allowing you to maximize your solar energy usage. - Battery Storage Capacity
Battery capacity is typically expressed in milliamp-hours (mAh). A higher mAh means the charger can store more energy, which is crucial for extended trips where you may need to charge devices multiple times. The right battery capacity for you depends on your energy consumption—for example, smartphones and GPS devices require less storage, while tablets and cameras may require more. Aim for a charger with a battery storage capacity that matches your typical usage needs. - Portability
Portability is one of the most important factors when choosing a solar charger for backpacking. Solar chargers can take up space, and generally, the larger the charger, the greater its storage capacity. However, advancements in technology mean it’s possible to find smaller, lighter chargers with higher battery storage. If you’re planning to hike for an extended period, consider solar backpacks that integrate solar panels, which offer both portability and energy storage without adding extra weight. Choose a charger that strikes the right balance between portability and capacity based on the length and type of your trip. - Durability
Backpacking exposes your solar charger to rough conditions, including extreme temperatures, dust, rain, and impacts. Therefore, durability is crucial.

How Many Watts of Solar Battery Charger Do I Need for Backpacking?
Determining how much wattage you need from your solar charger depends on your device consumption and how much solar energy you can gather during the day. No two hikers have the same energy needs, so it’s essential to calculate how much energy you’ll need to power your devices throughout your backpacking trip.
Step 1: Calculate the Energy Consumption of Your Devices
To start, the energy consumption of your devices is typically measured in Amps. The higher this number, the more energy the device consumes. For example:
- A smartphone might require around 5W to charge.
- A camera or small laptop could require 10W or more.
Next, to determine how much energy your device consumes in one day, you’ll need to know how many hours you’ll use the device in a 24-hour period. The energy consumption in Amp-hours (Ah) can be calculated as follows:
Amps x Hours = Amp Hours (Ah)
Step 2: Solar Panel Output and Wattage
Solar panel output is typically measured in watts (W). The higher the wattage, the more electricity the panel can generate. To calculate how much wattage you need from your solar charger, consider the following factors:
- How many devices do you need to recharge and their energy consumption in Amps?
- How many hours each device needs to be charged in 24 hours?
- The battery capacity of your solar charger.
- How much sunlight you can capture during the day?
Step 3: Example Calculation
Let’s imagine you need to recharge a 12V battery, and you have a 100W solar panel with an output of 30 Ah in a 24-hour period.
To recharge a 12V battery fully in one day, you’d need to know how much wattage is required. The formula is:
Volts x Amps = Watts
So, for a 12V battery that needs to be recharged with a 100W panel:
- 12V x 30A = 360W
This means you would need 360W worth of solar panel output to fully recharge a 12V battery in 24 hours.
Step 4: Consider Multiple Devices
If you plan to recharge multiple devices (for example, a smartphone, camera, and GPS), you need to account for their combined consumption. For instance:
- Smartphone: 5W
- GPS: 10W
- Camera: 10W
If you need to charge all three devices simultaneously or over the day, calculate the total energy consumption and multiply it by the required wattage of the solar charger. You’ll want to ensure that your solar panel’s total wattage matches or exceeds the combined power requirements of your devices.
Tips for Using Solar Battery Chargers Safely
