Recommended folding solar panels
We’ve rounded up five of the best folding solar panels to help you determine which one is best for your needs. The BigBlue, Jackery, and the NekTeck charger are best for smaller electronics and as transportable chargers.
If you need more power than a small portable panel can give you, the Renogy 100 watt off-grid portable solar panel suitcase is your best bet. For instance, if you need a foldable solar panel to charge a lithium 12v battery such as in your car or on your boat, you cannot just rely on small options like the BigBlue, which will not fully charge your car battery.
Each of these options offers great features for your everyday charging needs. Check them out below.

A key thing to keep in mind if you are purchasing panels for large-scale uses, like the Renogy model for an RV, you might need to purchase an inverter separately. The inverter acts as an adapter for the electricity. Solar panels create DC currents, but to power electronics, the inverter converts them to AC currents.
You will not need to purchase an inverter for the smaller, foldable solar panels to charge cell phones or small electronics. Foldable solar panels are a great choice for several reasons, but they do have a few disadvantages. Let's take a look and weigh the pros and cons.
What are the pros and cons of folding solar panels?
Typically, folding solar panels are used because of their lightweight portability, making them a great choice for on-the-go use. What makes them great for outdoor use does come with a few drawbacks, though. Folding solar panels need full sun exposure and take a while to charge, so don’t plan on using them every day to charge your phone.
|Convenient||Needs ample sunlight|
|Portable||Long charge time|
|Practical||Depending on model, takes up a lot of space|
Folding solar panels are convenient, portable, and practical – making them the perfect tools in your on-the-go arsenal. For instance, you can pack up the BigBlue solar charger in your camping backpack and have a source of power for your cell phone, chargeable lanterns, or any other gadgets that will make your camping trip easier.
If you need a larger panel like the Renogy off-grid portable panel, the ability to fold it up and store it compactly in your camper is a huge bonus.
The downsides to foldable solar panels are that they need a lot of sunlight to provide consistent power output. They also have a long charge time and some models, like the Renogy, cannot be carried in your backpack. The Renogy and Jackery panels are known as solar panel suitcases and are light enough to fold up and carry, but too big to fit easily in a bag.
Because foldable solar panels are small and less powerful than a large panel you might install on your roof, they need exposure to ample sunlight to be able to charge devices. So if you are caught on a cloudy day, your foldable panel might take longer than anticipated to charge your cell phone.
Additionally, solar charging takes a bit longer than your average wall charger to power up your phone. So instead of becoming 100% charged in about an hour, it might take the afternoon depending on the wattage of the panel you use and the amount of sunlight available.
Best uses for foldable solar panels

Foldable solar panels are best put to use when you have no electricity available. You can keep one packed and ready to go for trips to the beach, hiking, or camping. This way, you can spend the whole day outdoors without having to worry that your electricity will run out!

If you need a foldable solar panel to power things more energy-intensive than a phone, options like the Renogy or Rockpals panels can be used to charge the batteries of your RV, boat, or even your car. If you don’t want a noisy, polluting, gas-powered generator, foldable solar panels can act as a solar generator and be your backup power.
How to choose the right size and type of folding solar panel
Choosing the right foldable solar panel for you depends on a few factors such as what device do you plan to charge and how much power you need. For example, if all you want a charger for is small devices, the BigBlue, NekTeck, or Jackery are all you need.
But if you need enough power for your entire RV, you might be able to get away with one of the Renogy off-grid panels. But depending on the wattage you need to supply, you might need more than one.
If you are concerned that you might need more wattage than one panel can provide, you can calculate the typical energy usage of the appliances in your RV. You can do this by either using a battery monitor to measure the amount of energy, or amps, each appliance uses.
Many appliances have the amount of energy they use listed on them. You can easily add up the watts and determine how many panels you might need to power your RV.
But if you want to be less precise, buying three or four 100W panels, or 4 Renogy kits, should do the trick. Keep in mind that monocrystalline solar panels are more efficient than polycrystalline panels, so if you have less space, monocrystalline is a better choice despite its price tag.
Foldable solar panel chargers: are they right for you?
If you are ready to hit the hiking trail, adding a lightweight foldable solar panel like the BigBlue can be a simple way to keep your phone charged and your mind at ease. Folding solar panels offer the versatility and the freedom you want when enjoying the outdoors.
For your RV trips, don’t spend extra money on a gas generator. Simply pack a foldable solar panel, pop it open when the sun is out, and charge away. If this type of freedom and practicality appeals to you, adding solar panels to your home will let you generate your own energy while reducing your electric bill.
- Folding solar panels can be small enough to fit in your backpack or large enough to power your RV.
- Folding solar panels are convenient, practical, and portable, but they do need full sun exposure to best charge devices.
- The best use for folding solar panels is for any outdoor activity where you need access to electricity but the sun is your only choice.
