What Are The Top 5 Portable Solar Chargers?

The sun is the source of pure reliable solar energy. Solar-powered devices use an effective photovoltaic technology to convert light energy into direct electrical charge for powering batteries, to run calculators, watches, lights and similar mobile devices. We will look at the top 5 portable solar chargers for your on the move lifestyle.

Modern gadgets are regularly equipped with rechargeable batteries that can be charged using a solar-powered charger. Your laptop, iPad and cell phones  can connect to these chargers.

With any one of the top 5 portable solar chargers, you can charge a backpack full of gadgets that have been integrated to work with this technology. 

Top 5 Portable Solar Chargers

Solar chargers are not the one-size-fits-all solution: but they are available for different voltages. And you can buy a solar charger according to your gadget power requirement.

Most of the top 5 portable solar chargers come in battery capacities of 12, 24, and 36 volts.

There are also battery chargers as low as 3 volts that can be used to for charging a 6-volt NiCad cell phone battery.

How Solar Chargers Work

These portable solar panels convert light energy into electricity using a photovoltaic principle where light particles (called photons) impact layers of crystalline silicon, which cause electrons to move or flow. Solar panels produce electricity as direct current (DC).

The products below are all portable solar chargers but they have features that make them each different from the others.

Benefits Of The Top 5 Portable Solar Chargers

  • Solar chargers are fully mobile. These chargers can move with you attached to your appliance charging it while you go. It's the perfect companion for travellers and campers.
  • There are no emissions, waste or by-products.
  • They are cost efficient. Your charger doesn’t require an electrical point. They make power while the sun is visible and you save having to ever buy and dispose of non-rechargeable batteries. Plus, there are absolutely no maintenance costs.
  • There is total independence from electricity plug in points: solar chargers need no electrical connection. If you are a camper or a hiker, then solar chargers are your best friend.
  • Some advanced versions of chargers are also available with a waterproof exterior.  So, even if the weather is a combination of a sun and rain during the day, the charger works.
  • Some solar battery chargers have an internal battery so that you can charge a gadget and store solar energy for using later. Solar chargers without this inbuilt storage generally charge the gadget's battery and run the connected appliance in real time.
  • Internal battery storage comes in handy when there is no time, opportunity or sunlight available. Set the solar charger with built in battery up at the home camp spot while you explore and use the battery to charge phones overnight.

Disadvantages Of The Top 5 Portable Solar Chargers

  • Solar charger panels can be fragile with very thin silicon crystalline layers bedded in vinyl material develop cracks. When the glass panels develop cracks their efficiency falls and they are not as robust.
  • Solar panels need steady sunlight to provide power and some devices can still do that from diminished or dappled sunlight, their efficiency drops. Walking with them on a backpack means the solar access is intermittent and in poor weather they can become ineffective as a solar charger.
  • If you are a camper or a hiker carrying a solar power charger you do not need an electrical connection. However, solar chargers are slower than mains power chargers, especially when it comes to portable panels being carried on a backpack in poor or dappled sunlight.

Types of Solar Panels

There are three types of solar panels, each having advantages and disadvantages:

Understanding them may help understand whether features of your charger panels will affect the devices in particular lighting environments.

Features Of the Top 5 Portable Solar Chargers

Number of Devices

A key consideration for the right size of your charger is the number of devices you plan to charge using the solar charger. A charger with multiple USB ports will be able to charge several devices at the same time, thus saving time.

Take into account the number of devices being carried by you on your trip, and also the number of people going along with you with similar devices. 

Compatibility With Other Devices

The charger you carry needs to be compatible with all the devices you intend to charge with it. Bear in mind what kind of devices you expect to charge, as it is possible one charger won't fit all things you carry or work well in all environments.

You might be able to help someone else if you have spare capacity or even borrow capacity from them. You don't want to be carrying around multiple chargers.

Solar Charger Ports

Some chargers recharge a device directly from the solar panel while others do it through an included rechargeable battery.

Select the type of charger that suits your needs.

Check to see if the solar charger has USB ports, micro USB ports or both types.

Power Output

Depending on your needs, you can select from a 2.5 watts (for cell phones), 5 watts (for iPhones), 10 watts (for large-screen smartphones),  or even 50 watts solar charger (for laptops).  

Different chargers have different charging and re-charging time frames. The bigger panels usually provide more power more quickly.

Remember that portability and weight are important when planning to be on the move (hiking where you are charging your devices throughout the day on the go need lighter efficient chargers), or maybe bigger and less portable efficient charging for when you plan spending that time fishing and camping.


Look at the design of the charger and see whether you can fold it so it can be carried on or in a backpack.

And does it come with carabiners that enable you to hang it on your backpack while you move around to catch the sun while you walk?

Decide if you intend to actually use the solar charger while you are walking, hiking and moving about or will you be returning to a central camp location and charging the devices there.

When camping decide to buy a solar charger that is flexible and suits what you intend to use it for. Yes something small, lightweight and portable can power a mobile phone in direct sunlight. But that can take much longer to charge when moved in and out of the sunlight.

Likewise, when you think about the charger output, and the number of ports, how many gadgets will you actually need to take camping or hiking?

Add-On Features

When you are out there doing the hiking trips, a good solar charger must-keep on going through all conditions.

That means waterproofing, dust proofing, and shock resistance are essential solar charger life extenders.

Solar Charger Accessories

Clamps for attaching the charger to trees, tents, and backpacks are an important accessory that makes it easy to charge the batteries while you are stationary.

Extra connection cables as part of the solar charger kit design can set one charger apart from the others.

Charge Interruption And Recovery

When chargers feature a power pack, which provides power when and if the light source is disrupted by shadow they continue charging and powering at the same time.

This is similar to an uninterruptible power backup battery, which keeps you powered up after the electricity flow fades or stops. Without this feature some chargers will need to be reset after a temporary disruption.

Solar Charger Speed

Charger speed is important! 

When you have been hiking away from camp base, it's late in the day and particularly if your phone has lost charge while taking a million pictures or video, and you need to make this call, to provide information or to get help.

You may have a limited time to make the call (the sun is setting) and a fast charge speed is paramount to making the contact or not.

Portable Solar Charger vs Portable with Battery Pack

If you buy a portable solar charger like the Jetsun Solar you will get a small portable charger with an internal battery pack. They give you a charge during their hike but need putting onto a power socket in the evening.

The portable fold out solar charger is ideal for someone like an engineer who might spend time in a vehicle working and talking over the issues. While you do that fold out the solar panels and lay the charger panels in the windscreen on top of the dashboard and charge the device of choice. 

As a civil engineer myself I know no engineers who strap one of these charging panels on their back while they walk around or survey the area.

It's much easier and more convenient to fold out a solar charger like the Rockpals 100W or the 20W X-Dragon  and charge a phone, GPS or battery pack brick while it is positioned under the solar panels resting on the windscreen. You can work in the field while the batteries are being charged. A solar charger will re-energise the Jetsun solar battery pack while the vehicle is parked in the sun.

For day hikes, a battery pack has plenty of power for your phone, GPS and camera too. If you get a battery pack to attach to your solar charger find a battery pack with sufficient capacity so you won’t drain it after only one gadget has been plugged into it. A standard compact, lightweight power pack could charge an iPhone X twice.

With thin film solar innovation we have choices that include the rollable solar panel chargers that can be rolled around the battery tube. I have not used those products but they present a portable alternative to the multiple fold panels reviewed above.

Portable chargers can be rolled and carried comfortably in a backpack and is easy to set up. Apart from the comfort of carrying it, the rollable solar panel is easy to pull out, set up and put away. One is pictured below.

Top 5 Portable Solar Chargers

Rollable Solar Charger

The material used in these chargers allows the panel to fold like a sleeping bag. These solar chargers are made to allow flexibility.


I hope we can help you choose a portable solar charger.

Our recommendation for the best charger is the Rockpals 100W, mainly because of its capacity.

It is bigger and a heavier than the others, and possibly an unfair comparison when all the other panels are in the 20W range.

There is a Rockpals 30W solar charger option with three panels.

The compatible battery bank with our preferred 100W solar charger is the Jetsun Solar charger 16750mAh because it will hold power in the after hours that it received while sitting on your dashboard. These two devices will work together and separately.
