I think we can all admit that flashlights are pretty cool devices. Whether you need to power your way through a power outage or repair your car in the dark, nothing can help you quite like a handy little flashlight. But the great thing about flashlights is that they don’t necessarily need to run on standard batteries. As a matter of fact, you can get flashlights which run on solar power—which is not only good for your wallet, but also for the environment. How cool is that? Cool enough, indeed, that it merits an examination of how they work, which we’ll take a look at in the next section.

You must have noticed that there are literally hundreds of options available when you go to buy a solar flashlight. We have analyzed a wide range of solar powered flashlights and these are our recommendations. We hope that this will help you!
- 22 years of burn time if used at night (11 if used on LED)
- Can hold 1 charge for 3 years
- 100% waterproof up to 80 inches of depth
- Floats in water
Strong, durable design
One major benefit of using this flashlight is that it has a strong, durable design. It can be used in water, for example—it is 100% waterproof, up to a depth of 80 inches—and can even float in water. The design features two powerful LED lights. Finally, the design is lightweight; it measures about 7 inches long. It is black in colour.
If used at night, its light can last for 22 years (or 11 if the LED setting is employed). The light is not affected by high temperatures. It can last for years and years; indeed, even a single charge can last for three years on its own. You can throw it aside in a drawer and pick it up three years later, and it will work like new. You don’t need to store it in the sun to make it work; it stores the energy on its own and releases it on command. Their lithium backup batteries last a long time and are affordable and easy to replace when the time comes. The centre area of the light creates brighter light, with a diameter of maybe about 1.5 feet, whereas the outer circle surrounding—this one measuring 8 feet—is made of diffused light. In other words, this flashlight creates a wide circle of illumination around you.

Versatile functionality: charge it in different ways
You can charge this flashlight in different ways: via the included solar panel so that it will gather in the sunlight and convert it to energy; via a USB charging cable; or via the hand crank, which you can crank for 1 minute (at 120 rpm) to create 10 minutes of light. To support such cables, it features a 1.5A USB port, and an included USB charging cable. To charge it, it’s ideal if you leave it in a windowsill so that it can passively store the energy when you’re not using it.
A terrific way of creating light
The light produced from this flashlight is strong and powerful, thanks to the 4400-mAH lithium battery. The total output of light is 250 lumens. The run time can last from 7 to 48 hours, depending on how bright you have the light settings set to. There are also multiple options for light; there are modes for bright, half bright, floodlight, or emergency light.
Balanced, ergonomic design
The design is ergonomic, so that—when you hold it in your hand—it will feel nice and balanced, with the weight evenly distributed across the different parts of your hand. It will feel nice and comfortable so that there is no unnecessary strain on your hands if you’ve been holding it for a while.
- Solar panel is built-in
- Dynamo-powered hand crank
- No need for batteries
- One hour to charge
- 3 powerful LEDs
Effective charging method
You can charge this flashlight by leaving it out in the sunlight and waiting for it to gather in the light, then convert it into energy to charge the battery. However, if you get stuck in a bind—i.e., it isn’t sunny outside—then you can simply charge it by turning the hand crank, which is powered by a dynamo generator. If you crank it for one minute, you’ll get lighting for 80 minutes (almost an hour and a half). As a result of all this, you won’t need to worry about charging a battery when you need more light since no battery is included.
Excellent source of illumination
There are three powerful LEDs to provide you with all the illumination you’ll need for hiking, camping, boating, and emergency uses. There are different modes for the light: you can have one LED on, three LEDs on, or the three LEDs on and flashing at the same time. The solar panel is built-in.
Strong and durable
This sturdy flashlight is wind- and rainproof, up to 45 feet in total, so you won’t have to worry too much about intense weather conditions if you plan on taking it outside. It is also totally waterproof because it’s designed to be used continuously during floods, storms, and other such weather eventualities.
How Do Solar Flashlights work?
Like other solar-powered devices, solar flashlights work by gathering in energy from the sun, which they can do so via their photovoltaic (solar) cells. Although the bulb can vary, they have often LED lights. Solar-powered flashlights have batteries, but they don’t need to be replaced as often as is the case with normal flashlights. They are an ideal choice for emergency kits or bug out bags, and are exceptionally helpful for those who live in remote areas where solar power is one of the main energy sources. With such flashlights, you can see easily see objects that are up to 50 meters in the distance; however, beams of light being emitted from the device can be seen from much farther distances. The light can generally last for five to seven hours, if not more.
Things To Consider When Buying Solar Flashlight
If you’re buying a solar flashlight, you need to find the model that’s right for you. In order to do so, there are several things you’ll absolutely need to take into account before you bring your flashlight to the cash register, or hit “send” on Amazon. If you don’t, then you risk wasting money on a flashlight which you’ll never use because you don’t like it. Therefore, be sure to watch out for the following considerations when it’s time to purchase a solar flashlight. They can help you make the best decision, by finding the model that’s perfect for your tastes.
How portable is it?
Naturally, all flashlights are portable, but some are more portable than others, in that they’re lighter or easier to carry. In this case, the specific dimensions of the flashlight will depend on how you need to use the light. If you only plan on using the flashlight occasionally, such as during emergency situations, then you’ll probably be okay with a model that’s heavier. If, on the other hand, you use the solar flashlight more often—like if you use it at work, for example—then you’ll want a model that’s more portable, in that it’s lighter and the shape is less unwieldy. Moreover, smaller solar flashlights can easily be stored in a bag, a small purse, or even on a keychain; you won’t be forced to store it in the trunk of your car.
How does the light come out?
Some flashlights will create brighter light, whereas others will generate a more subdued lighting scheme. Keep in mind that you won’t be able to see anything with a brightness level of more than 150 lumens, so you’ll want to avoid such models, as they will cause you to squint and not be able to see properly. Even in the case of 150 lumens, that’s still quite a lot of illumination and is not necessary for most uses of solar flashlights. You can settle for less, such as 75 lumens, if (for example) you keep it on your person when you’re out walking your dog. 100 to 150 lumens is ideal for camping or hiking, however.
Controlling the light
However, one thing to keep in mind—aside from the brightness of the light—is how you can control the light. This is often done with a switch that you can use to turn it on or off. Depending on the model, you might be able to push this button with one hand, even if the flashlight model itself requires two-handed usage. You can also get models with simple switches that can be easily flipped on or off. On the other hand, some models will have more sophisticated controls. Thus, some models will allow you to change the mode from floodlight to spotlight, and so forth.
Will it last for a long time?
Many flashlights won’t work for more than a few months, and this consideration also applies to solar-powered flashlights. Thus, carefully examine the reviews of any flashlight you’re interested in before you make the purchase, to make sure that this problem doesn’t come up. After all, you’d ideally like your flashlight to last years and years (and not a few months).
By now, hopefully, you know a little more about purchasing your next solar flashlight. In this article, we’ve suggested ten different models of flashlights to help kick on your search. However—if you find that these models aren’t quite to your taste—don’t despair. There are hundreds of models offered on the market, so—if you do your research carefully—you will be able to find the perfect flashlights. We wish you the best of luck in your search; we know that you will find a great model. And finally, don’t forget to take into account all of the things we mentioned here today. They will help you find a flashlight that is highly compatible with all your needs.
