Solar flashlights are a step further than conventional flashlights. Rather than relying on on-grid power sources for recharging batteries, these flashlights are powered by instant solar power. Not just that, a few of these devices can also be used as power banks, so you can charge more electric devices using the same solar power collected by these flashlights.

Many features differentiate solar flashlights because they are offered at different price points. In this article, we have reviewed some of the best products in this category. We have also created a buying guide that mentions the essential elements that you should be aware of. So take a look, and let’s find out which flashlight is the perfect match for you.

How Do Solar Flashlights Work?

Whether you’re new to solar power, or an old hand, it’s always worth reading up on the product you’re about to buy. Take a moment to learn about the inner workings of solar flashlights.

Whilst the primary function of a solar flashlight is pretty obvious, what is less so is all of the additional features built into these models. Solar flashlights can come with any number of secondary functions and handy in-built tools, including but not limited to: red/blue strobe warning lights, waterproof protection, telescopic zoom, portable charger/power bank, USB charging, SOS lights, magnets, hammers and ‘seatbelt cutters’. Of course, these functions are of secondary importance, what you need to know is how the flashlight part of the product works in the first place.

Solar flashlights are sturdy, weatherproof metal, handheld rods housing high-powered LED bulbs of luminosity up to 1000 lumens. They have an ON/OFF switch, and can generally be charged either by USB cable or by solar. For solar, they are installed with durable monocrystalline (or polycrystalline) solar panels in the grip, which need to be exposed to sunlight in order to charge the device. During exposure, the solar panels convert sunlight into consumable electricity, which is stored in the flashlight’s rechargeable Lithium Ion battery, for later use.

But how does the solar panel generate electricity from sunlight? A solar panel is a waterproof and weatherproof module comprising many smaller solar cells. These cells, made of a particular silicon, undergo a chemical and physical reaction (known as the ‘photovoltaic effect’) when exposed to sunlight. Sunlight pushes electrons from one layer of silicon to another, a process of displacement during which volts of electricity are naturally generated (to be stored in the aforementioned battery). This process is cyclical, and occurs repeatedly for as long as the panel is exposed to sunlight.

Pros and Cons of Solar Flashlights

Let’s take a quick look at all of the most important pros and cons associated with solar flashlights.

Pros:

  1. Highly-powerful. Solar power is, contrary to common misconception, just as powerful as grid electricity. This point is proven by the extraordinary luminosities of these flashlights, which can often have irradiation ranges of up to 300 metres.
  2. Emergency friendly. Unlike conventionally-powered gadgets, a solar-powered one will always have access to power, and thus will always be prepared for an emergency, such as a power outage.
  3. Free electricity. Renewable energy means you don’t have to pay a cent for the electricity your flashlight consumes.
  4. Many additional features. The copious number of additional features associated with these flashlights increases their usefulness exponentially.
  5. Affordable. Even the most powerful flashlights, with the most useful additional accessories, are often only around $20 – and that’s not to mention the ones which come in far cheaper.

Cons:

  1. Slow charging time. Whilst you can charge almost all of these flashlights via USB, the point of them is that they are solar-compatible. Unfortunately, full-charging via solar can require up to 40 hours of sunlight exposure.
  2. Sunlight dependent. On top of slow charging times, bear in mind the fact that solar panels require sunlight in order to generate electricity – a resource which, whilst free, can vary greatly in availability.

Some devices offer a single brightness level, while others offer multiple options, and you can choose the option according to your requirement. For a better user experience, you should consider buying the latter option.
