There has been a significant advancement in solar technology since it first debuted in the 1960s. Initially, solar photovoltaics had been regarded as a thing of the future. But today, they have spearheaded technological breakthroughs, resulting in an array of solar-powered devices that include backpacks, lanterns and flashlights.
Our point of focus today is on solar-driven flashlights. We’ve highlighted the benefits they offer over conventional models, and recommended the best solar flashlights on the market.
Why You Should Consider Solar Flashlights
The greatest benefit of using a solar flashlight is the fact that it relies exclusively on sunlight as a source of energy. There are a couple of models that use hybrid mechanisms, meaning they use a combination of solar and chemical energy. But even then, these have minimal effect on the environment.
To show just how eco-friendly solar flashlights are, it helps to explain how the latter work. Conventional flashlights are powered by rechargeable or disposable batteries. The production of these batteries involves the use of chemicals such as cadmium, lead, nickel, mercury, lithium and electrolytes. The worst bit is that these batteries are difficult to dispose of safely.
If your flashlight uses disposable batteries, then it’s likely that you dispose them along with other household trash. Ultimately, the batteries end up in landfills. As the casing of the battery begins to corrode, the chemicals used in its production leach into the soil, and find their way into water bodies.
Worse even is the risk that lithium batteries can react in a volatile way when they’re exposed to the environment. They have the potential to cause landfill fires.
If you invest in solar flashlights, you don’t have to worry about any of these risks that arises from using battery-powered flashlights.
Plus, you have a ready source of energy. Whenever there’s a power outage, all you need to do is find your solar flashlight and switch it on. No need to start purchasing disposable batteries or searching for a means to recharge your rechargeable flashlight.

The flashlight is incredibly lightweight, tipping the scales at 4.5 ounces. It measures 6 inches long and has a diameter of 1.75 inches, meaning it’s not too bulky that it can’t fit in your backpack. Also, it has a polycarbonate shell that feels smooth to touch but is not slippery that it will slide from your hands.
Hybridlight Journey is equipped with LED bulb that casts out a 160-lumen bulb. It also has a decent runtime. When configured to a high setting, it can operate for up to 7 hours without being recharged. In the low beam setting, you can get thrice the runtime; at least 25 hours.
Speaking of recharging, you have two options at your disposal. The most obvious way is to expose its solar panel to direct sunlight. If it’s cloudy or rainy, and you need to use the flashlight urgently, you can charge it using incandescent lighting or by connecting to an outlet using the included USB cable.
The key highlight of this solar flashlight is the fact that it doubles up as a phone charger. Though used to store solar energy, the 2400 mAh lithium-ion battery can also be used to charge a cell phone and other small devices.

Simply, expose the tool to direct sunlight for a couple of hours and it will charge and provide illumination. One particular solar flashlight that we recommend investing in is the NPET T09 Solar Flashlight. A multipurpose tool, this flashlight doubles up as a safety hammer and seatbelt cutter.

Guide for Buying The Best Solar Flashlights
Ideally, all solar-powered flashlights should have a sturdy build. But you should pay more attention to this aspect if you plan to use the device outdoors more often than indoors.
If you like going hunting or camping, there’s a high chance that your flashlight will be subjected to a rough terrain. If it’s not hardy enough, it might not withstand to these elements. To determine how durable your solar flashlight is, look for descriptive terms like “shock-resistant” and “waterproof”.
However, if you don’t plan to use the flashlight as much outdoors, a simple emergency back-up unit will suffice. It doesn’t have to be water-resistant but it should still be made of quality materials.
Size and Weight
There are significant differences between solar-powered flashlights when it comes to the size and weight. The design of the flashlight you choose will depend on your intended purpose. If you’re planning to use it in an outdoor setting, you should opt for one that’s incredibly lightweight.
Keep in mind that flashlights weigh heavier when they’re equipped with additional elements like window shatter tools. Solar panels built into these devices also vary in size, which ultimately affects their overall weight.
For outdoor applications, consider buying a compact unit that can easily fit in your camping backpack. It also shouldn’t have too many features that add up to its weight.
There are three main techniques of charging a solar flashlight. Top-rated units include a minimum of two of these charging methods:
Given that we’re referring to solar-driven gadgets, it comes as no surprise that solar power is a necessary charging method. With solar power, you’re able to charge your flashlight at no additional cost. The only challenges are that it’s a bit slow and exclusively relies on light- preferably direct sunlight.
If you’ve been shopping for a solar flashlight, you’ve probably noticed that some models also allow for USB charging. This offers convenience when you need a fast way to charge your flashlight. Plus, it provides a decent amount of charge, which can then be topped off as needed.
That said, this mostly applies to solar flashlights used indoors. This way, you have a ready source of power to charge your device.
Another technique of charging your solar flashlight is hand cranking. Simply turn the crank for a couple of minutes and you’ll get at least an hour of charge. Often, users resort to hand cranking when they have no access to either electricity or the sun. The good thing is that this approach gives you instant charge to work with, which can come in handy in emergency situations.
Another vital aspect to consider the length of run time of the solar flashlight. This is particularly important if you’ll be using it for long stretches at a time before recharging. Some quality flashlights can last for as long as 10 hours. Others can only work for a maximum of 3 hours. Generally, the standard run time for this type of flashlight is 4 hours.
If you want to get the most run-time, consider buying a flashlight with different modes- preferably the dim or low modes. This way, you can configure it to run on the low mode when you want to save on charge.
The length of time that a solar powered flashlight takes to recharge will differ from one model to the next. The recharge duration is also affected by other factors such as technique of charging being employed (with USB connection being the fastest), size and efficacy of the built-in solar panels.
The angle at which you place the flashlight when recharging using solar energy, and the intensity of sunlight also play a huge role in determining the recharge time.
Most solar-driven flashlights will have one or more LED bulbs. Still, some produce greater brightness than others. If you’ll be using your flashlight in low-light conditions, consider choosing a unit that is bright enough for that application. It should be capable of producing 150 lumens or more. Also, it should be able to illuminate up to several hundred feet. The downside to this is that a bright flashlight will also drain the charge much faster.
It helps to choose a flashlight that has different modes. Most of them will offer a bright and dim mode. The benefit of this is that you can switch to the low-light setting whenever you want to save on battery. Some flashlights have up to 7 different modes that include slow or fast flashing lights for emergency situations as well as running lights.
Some solar flashlights are highly-versatile. They’re equipped with extra tools that make them handy for emergency situations. The most common tools included are:
- A seatbelt cutter
- A compass
- A window shatter tool
