Charging the phone

A solar charger usually takes 20 to 30 hours to fully charge a modern smartphone. The biggest limitation of portable solar chargers is the amount of energy they can generate. This phenomenon is exacerbated by environmental factors such as dust on the panels and available sunlight. As a general rule : The larger the panels, the better the performance.

It is best to use a portable solar charger with a built-in battery or a portable battery with a solar charger. After all, you don’t want to sit around all day waiting for your phone to charge, and unless you have a long cord, the direct sunlight required for a solar panel is usually not very good for phones.

A few words about direct sunlight

Do solar chargers need direct sunlight? The short answer is: No, you don’t have to do that. The solar modules in most chargers must be able to store energy even without direct sunlight. Portable solar chargers with built-in charging indicators allow you to observe this even if you are in a shady area on a sunny day.

Direct sunlight is always preferable for a more efficient charge, but if you don’t want to change the panel’s position every hour, you can charge it properly by placing it in an open, upright position. word-image-8275

Autonomy of solar battery

In the past, solar modules were extremely inefficient and had a short lifespan. Technological advances have improved them, and you can expect a solar charger you buy today to last about 25 years. Provided you keep the panels in good condition and do not damage the electronics inside. Therefore, it is useful to think about the scope and type of activities you plan to undertake during your trip.

How to choose a portable solar charger?

Look at the amount of energy produced and see if it meets your needs. Smaller, less expensive models are usually suitable for mobile phones. However, if you need to charge a laptop or other large device, choose one that generates more power.

Can a solar charger affect my battery life?

In short, usually not. Most portable solar chargers charge slowly at a very low voltage. This may mean it takes longer to charge, but the effect should not damage the battery. However, always check your requirements and policies to be sure.
