How to Choose a Solar Powered Flashlight – 3 Things to Think About
One of the first things that you should think about is related to the charging methods. Solar powered flashlights should always have at least two charging methods. The most common or popular ones are solar, USB and hand cranking.
Having multiple charging methods allows you to have a more reliable light source that will not fade away when you need it the most. Solar is an inexhaustible source of power, but it’s also dependent on the weather, which is why is good to have the possibility to either use a USB connection (where you will need to find something to charge your flashlight with) or to use hand cranking. The last method is probably the most reliable and efficient method that can be used.
The second fact that should be considered is the working modes for solar flashlight.
Having a reliable source of light is also related to the intensity and the use of such light. Some lights have working modes intended for high intensity and low intensity as well. It is highly recommendable to keep in mind that the most important reference here is the lumens output.
Some lights will be as bright as 200 lumens while others can be as soft as 3 lumens which would make them similar to solar powered camping lanterns.
Emergency modes and also different lighting modes (floodlight, spotlight, red lights) are also important factors that you should take into account for the outdoors.
Finally, what may make you select one or another flashlight may not only be related to its specs but due to its unique features. Things like design, portability, color, additional tools such as window breakers, magnets, seat belt cutters, color charging indicators, durability, or waterproof ratings, may help you decide which is the best product for you.
What are the Different Types of Solar Flashlights?
There are several types of solar flashlights.
There are those called hybrid solar flashlights which use a battery backup device that offers the option to replace the battery instead of simply charging it, these products tend to hold the charge for longer periods of time.
There are also those solar flashlights intended for car emergency situations. These are probably the most useful among all flashlights since they can be used not only as light sources but also as handy tools that contain hammers, seat belt cutters, compasses and more. They are typically charged under solar and USB cables.
Then, we have solar flashlights designed for camping and hiking activities. These products are typically waterproof since they are intended to work in outdoor conditions that could imply water. They are also resistant to damages and made of durable materials.
Finally, an important characteristic is that these camping flashlights have at least two charging methods: solar and hand cranking. Solar energy should be a reliable source of power for the product, however, in case that you forget to charge the flashlight before using it or that the battery simply runs out of power, then the hand cranking tool will become very handy as this will ensure you will not stay without light in any situation, no matter time or weather forecast.
How do Solar Flashlights Work?
Similar to other solar powered devices that can be used in the outdoors such as solar phone chargers or solar powered watches, the solar flashlights have a small integrated solar panel that when exposed to direct sunlight, can convert the sun’s energy into electricity.
This energy conversion is done at a microscopic level and it simply involves the conversion of the kinetic energy of small particles contained inside light (called photons) into electricity which is another form of energy that uses the movement of electrons to make an electric current flow. This electric current is later saved or stored in a nickel-metal-hydrate or lithium battery for later use.
This is the basic characteristic that every solar flashlight must have. Others have a USB connection port that allows them to charge the battery just as you would charge any other USB device.
Some solar flashlights will have a hand cranking charging method. This consists of transforming mechanical energy into electricity and this is easily done by using one of the oldest machines in the electricity industry: the dynamo.
Also known as a direct current generator, the dynamo uses the rotational mechanical movement to impulse a direct current in its output terminals. Later, this generated current goes to the storage device.
What is the Charge Time and Battery Life of the Average Solar Flashlight?
Charging times for each charging method are extremely important to consider as sometimes charging times could be too large as to consider it a reliable light source.
For solar power, charging times generally take between 7-14 hours, basically, the flashlight should not take more than two days to reach full charge. For USB charging, flashlights generally take between 3-5 hours, up to 6 hours should be enough for this method.
Meanwhile for hand-crank modes, spinning during 1 minute should give you enough power to have a source of light for at least 30 minutes.
Working times are also crucial for selecting solar flashlights. This is entirely dependent on the working modes and on the battery life, choosing a higher battery capacity will give you higher working time. However, you must balance this with the charging time required to reach full charge.
Working times, in general, are located between 4-8 hours.
How to Protect Your Flashlight From Being Damaged?
A solar flashlight can be very different from the other. Some models may be more durable or strong than others. You may even see some videos where the flashlight can be used to break glasses and where the manufacturer passes a vehicle above the flashlight. It’s hard to think that you may do some damage to these models.
Nevertheless, another factor that you should be careful about is related to water protection. If you intend to use the solar flashlight for camping purposes or especially for outdoor adventures such as fishing, kayaking or sailing, then having a flashlight with good waterproof rating protection is extremely important. If your purpose is to keep the light inside the car as a car emergency flashlight, then having a waterproof rating may not be as important.
