Things to Consider Before Buying

If you consider improving your next outdoor expedition with one or more portable panels, it’s important to know what you want. Below we’ll discuss some of the most important features that you should definitely include in your shopping experience when comparing products.

Ease of Use

Just think about this situation: your phone is dying and you need to call for an emergency situation or you need to check your GPS coordinates. In such a situation, you need access to quick energy and you don’t have the time or the will to decipher complicated instructions.

A portable solar panel must be easy to install and operate since you don’t have a specialist with you. Everything must be as simple as opening the panel, placing it in the sunlight, and charging your devices. No fuss, no complicated instructions, no brain teasers.

That also means that there shouldn’t be a large bundle of cords to get tangled in; look for panels that have the most important charging ports to fit your devices (USB is the most popular one).


You don’t need a panel that will weigh you down as you go up the path; after all you might be climbing a very steep mountain! If you are biking, hiking, or even rock climbing, your panel shouldn’t weigh over one pound. It must also be quite easy to fold and stuff inside the backpack in the event that your hands and arms get tired.

However, if you are boating or driving, weight doesn’t really matter so you can go wild with your choices. Still, some of the models we’ll discuss today can be used on a backpacking trip, while others are more suitable for boating trips or strapping to the roof of your car.


This means that your panel must be easy to move around and transport. Many of the products described in the review section are easy to fold up so that they can fit into a pocket of your backpack. These folded sections also make it very easy for you to strap the panels to the outside of your backpack so that the charging process can take place while you’re on the move.

After all, if you’re already outside, there’s no need to waste all of that solar energy while you’re rock climbing or just hiking up a nice trail. For most backpackers, the more lightweight the panel, the better.


Most models today can charge more than a certain type of phone or tablet. Due to the smart charging technology available today, most models can understand the devices you’re trying to charge and can offer the right amount of electrical power. This makes portable solar panels extremely versatile and quite easy to have around.

Look for panels that have both USB ports and DC outlets so that you have the option of charging larger devices as well. Even if you don’t plan on bringing mini-appliances with you, having the option is better than being without, especially if you’re in an emergency situation.


The most sought after accessory is an external battery. However, there are other things to consider like standing supports that allow you to position the panel easier, hooks so you can hang it over your backpack, pockets that protect your devices, cables, adapters, as well as other options.

However, which accessories you choose is dependent on how you’ll be using your solar panels. There’s no reason to throw money at options that you know you’ll never use.
