They’re compact and lightweight enough to be carried with you when you hear the call to adventure. If, like us, you’re tired of not being able to charge your phone in the middle of nowhere, join us in our quest to find the best solar charger for backpacking.

We’ll provide all the relevant data needed to determine what’s the best backpacking solar charger. After a few necessary explanations, and reviewing the best solar chargers we could find out there, you’ll know all there is to know.

From there, you’ll be a lot closer to indulging yourself in the conveniences of the modern era during your expeditions.


Factors To Consider Before Buying A Solar Charger for Backpacking

There are several details to keep in mind when you’re looking for the best solar charger for backpacking. To get the best performance you’ll need to take into consideration the following factors:

1. Solar Panel Size

The size of the solar panel is one of the main things to consider when you’re buying a solar charger. It will determine the amount of space available for photovoltaic cells.

A bigger panel will be able to generate a larger amount of energy. For backpacking, space efficiency is a must, so it’s smart to go for something foldable.

2. Energy Transformation Rate

This quantity is expressed as a percentage of all the available solar energy transformed into electricity by the generator. This means that a panel with higher transformation rates generates more power than an equivalent sized one with a lower rate.

It reflects the solar panel’s efficiency, and going for a better performance helps you save some space when you’re backpacking.

3. Energy Output

It’s important to understand that different devices require different energy inputs to properly charge a battery. The amount of electricity available to the user under optimal conditions will determine the time it’ll take to fully charge the battery.

If you charge multiple devices simultaneously,. the energy output will be distributed among the charging devices.

4. Compatibility

Most solar chargers don’t work with every device. Conflicting charging protocols could damage your battery if you’re not careful. Be mindful of the supported devices before connecting an incompatible power storage unit to avoid risking your battery.

Likewise, features like fast charging are only available to selected devices under optimal conditions.

Frequently Asked Questions

1. Do solar power chargers really work?

These solar panels rely on the sun’s energy to generate an electrical output. It’s enough energy to charge one or two devices under direct sunlight, but it may take a while. It mostly depends on the size and the technology employed to generate power.

In 2020, the best hiking solar chargers significantly reduced the amount of time necessary to fully charge the battery. Sadly, solar power chargers don’t work on every device. It’s important to check beforehand if your device is compatible with the solar panel to avoid battery damage.

2. Do solar chargers need direct sunlight?

Solar chargers won’t work at all unless they’re exposed to some degree of light. The energy is generated by an interaction between the photons that constitute light beams and the panel’s material. In this case, more light means more energy. The advisable conditions for the use of a solar charger would be under direct light exposure.

Nonetheless, they still work in non-optimal light conditions, but won’t be as effective. To make the most out of a solar charger, the use of a power storage unit is recommendedt. The battery will charge whenever an energy input is available, and the energy will be easily disposable under any circumstances.

3. How long does a solar charger take to charge?

The amount of time it takes for a solar charger to fully charge a battery depends on several factors. First, the battery’s capacity has to be taken into consideration. It takes longer to charge a 20.000 mAh power bank than a regular smartphone’s battery.

Then there’s the fact that solar chargers use the sun’s energy to charge the battery, so it won’t be as effective unless it’s exposed to direct sunlight. On optimal conditions and using the best solar charger, it would take about 2-3 hours to charge a cellphone. For a larger power storage unit, it could take a whole day to reach its maximum capacity.

4. What is the best solar panels for camping?

For camping, where saving space isn’t a pressing concern, it’s advised to pack a larger solar charger. With a larger solar panel, you’ll get better results at harnessing the sun’s energy to charge your batteries. Something with a good amount of charging ports would also be a valuable addition to your camping gear.

The best solar chargers considering these conditions were:

  • Foxelli Triple USB Solar Charger
  • Goal Zero Nomad 7 Solar Panel
  • RAVPower 21W Solar Panel

Versatility, effectiveness and endurance are assured if you take any of these solar chargers to a tent in the woods.
