Solar Powered Flashlights: 8 Models Which May Come In Handy When Hiking


Since flashlights are designed to help you see when it is dark, it looks like an oxymoron when you see a solar powered flashlight, but it may actually be a convenient thing to use: say, if you are hiking, you can charge it on the go, and use it when dusk hinders your journey. Besides, there are models which have an integrated backup battery to power your flashlight if the solar energy accumulated is not enough. Here is a list of flashlights that may come in handy and use sunlight as a source of power.

II. ECEEN Solar Flashlight

An elegant product, the ECEEN solar flashlight can be charged two ways: either via a USB cord or via the integrated solar panel. The sleek design is another advantage which contributes to the product rating, which is very good (4.5/5). The 1 W solar panel is small yet capable of supplying your flashlight with energy on a sunny day. Besides, there is a 500 mAh battery which can offer you backup energy in case it is cloudy. The best feature of the flashlight is its high quality lamp (1 W LED, 38 lumens) which can provide about 20 meters of lighting distance. Charging it with a solar panel equals 4 hours of charging it using AC charger and can provide enough energy for it to be used for 3-4 hours (here continuous usage is implied). The flashlight is made of aluminum alloy, which means it is lightweight and sleek. Besides, it’s said to be able to endure harsh weather, as it is waterproof. The anti-slip textured handle is another advantage of this well-designed product.

Note that it is recommended to charge it every 3 months even if you do not use it.

Feedback summary

The Amazon user named Hart posted a very detailed review which seems to sum up what kind of a flashlight this product is. According to him, the key advantage of the flashlight is that it is really bright, which is definitely a strong point for a torch, since it is its primary purpose and function. As to its drawbacks, there is a solar panel which is said to be 1 W, but its actual efficiency is not obvious: the plastic shield, dust and average weather conditions make the solar energy stored less impressive than it can seem. This user does not recommend to use it as an outdoors product and advices to charge it via a USB cord if the battery is drained completely and maintaining the energy level simply by putting it in sunlight getting to your room through a window. The item is well done and feels solid. Yet there is another point that must be noted: it’s not as waterproof as it may seem from the description: sealing is not reliable, because there are several places where water can get into the flashlight, so it can possibly survive a splashing followed by toweling off, but it certainly should not be put into water. All in all, if your conditions are not that severe, it can be a nice flashlight which is bright and able to be charged via sunlight if it’s not going to be needed ASAP.

 

III. PowerGreen Flashlights Handheld LED Solar Flashlight

This product features lamps which provide their user whooping 600 lumens enabling him to light up to 200 meters. There are three modes available: bright light, flashing light, and SOS. If the battery is full, you can use it up to 6 hours (continuously). There is one important note about the solar panel: it’s designed to be an emergency means of charging, yet it will turn on the circuit protection mode if the battery energy level drops to the extent it cannot charge a mobile phone. In this case, you will have to use AC to charge it. The aviation aluminum alloy makes it a well-built product which is lightweight and highly portable. The seller claims it can be charged via USB within 1 hour, and it takes 6 hours of sunlight exposure to charge it the eco-friendly way. There’s an indicator which turns red when the device is charging and gets green when charging is complete. Please make sure you cut the power off when it does need more energy! 

It can also be used as an emergency power source, and you can charge your phone with it via the USB cable which comes with the flashlight.

Feedback summary

The feedback present on Amazon is awesome: there are 55 reviews (as of October 2017), and the average rating is 4.9/5 suggesting it’s a product worth buying. Yet there are 2 critical reviews (versus 53 positive ones) in which people doubt the feedback is real. We do not know whether it is a bunch of fake reviews (though there are reasons to think so: the review content is not descriptive and the names used are also suspicious) or there is really good user experience behind them, so we are not going to cover its features described in the feedback and will just state that the rating is almost excellent (though the reason for it remains unclear).  

 

IV. iGadgitz Xtra 5m Waterproof Eco Rechargeable Solar & Hand Crank LED Torch Flashlight

The key feature of this solar powered flashlight is its impressive waterproof quality: the seller claims it can endure up to 5 m (45 ft) of water. There two ways to charge it: either by solar energy or by cranking. There are three LEDs. Besides, there are three working modes: low, high and emergency.

Amazon rating: 4.8/5

Price: $16.61

Feedback summary

Since there are many positive reviews (and these do not look as suspicious as the ones about the previous product), we assume it’s a product of high quality, though we still doubt that 1 minute of cranking gives you 1 hour of lightning, and 1 hour of direct sunlight gives you 1,5 hours of lighting. One user reported his test results: 1 minute of cranking gave him 2-3 minutes of light, while 6 hours of charging in the window in direct sunlight enables him to use it for 45 minutes.

 

V. Suaoki LED Camping Lantern

Well, it’s not a flashlight, but we couldn’t help adding this item in the list, because it is convenient and efficient. This lantern can be charged using the solar panel integrated in it, or a common USB cable. One of the key features of the model its collapsible design: it’s easy to store and carry, and it does not require much room in your backpack. There are three modes available: high brightness, low brightness, and SOS flashing.

Feedback summary

This product has a very good rating and many positive reviews. It is said to provide enough light, and the solar panel is decent. Yet there is one drawback mentioned in the not so numerous critical reviews: it’s rather flimsy, and it’s better to handle it with care. Other than that, it’s a convenient flashlight/lantern which can help you illuminate your way/table/tent when hiking or camping.

 

VI. Power Bank, PowerGreen Solar Charger with 32LED Flashlight

This power bank is characterized by the decent capacity of 10000 mAh, which makes it a full-scale power bank, so the integrated flashlight is more like a bonus. The seller notes that the solar panel is there to provide an emergency energy source, not the primary one, because the panel is small. There are 2 USB ports which enable you to charge 2 devices simultaneously: the first one is a 2A port (for iPads and other tablets), and the second one is 1A (for mobile phones). 4 LED indicators let you know whether there is much energy left in the battery. There’s also a special indicator for letting you know when solar energy is being stored. The 32 LED flashlight is a nice solution for those who need a bright torch. A clip makes it easier to carry the product. The item is characterized by good compatibility and can provide energy to 5 V USB devices.

Technical details

32 LED.

Amazon rating: 4.2/5

Price: $26.38

Feedback summary

There is a bunch of positive reviews suggesting it’s a good model which is well-built and powerful, but some customers doubt these are real: it is another case of possibly fake reviews, so it’s difficult to tell whether the information provided is correct. Yet there are a couple of reviews which sound reliable, and according to them, it’s a product worth buying.

 

VII. Solar and Dynamo Powered LED Torch + Mobile USB Charger

It is another model which combines a solar panel and a dynamo to power your flashlight. Besides, it’s a power bank for your USB-compatible devices. There are three lamps, and you can switch between a single lamp mode and a three lamp mode. The body of the torch is waterproof, so you can use it outdoors. The dynamo handle is foldable, so the item does not need much space. The seller claims it can provide up to 3 hours of lighting (if 3 LEDs are used) or 9 hours of lighting (if only 1 LED is used). The dynamo can be used to charge your cell phone, as it provides 4-5 volts. The item comes with a charger cable.  

Technical details

Dimensions: 55 mm x 115 mm x 40 mm (2.17” x 4.5” x 1.58”);

Weight: 115 g (4 ounces);

Color: black.

Amazon rating: 3.5/5

Price: $16.75

Feedback summary

The reviews posted on Amazon are mixed. The key idea of the reviews is that it’s a good flashlight, but it is difficult to charge your phone by cranking – 5 minutes of cranking give you 1% of phone battery, so it DOES work, but it is an emergency power source, and you must realize that cranking cannot provide you lots of energy in a moment. The solar panel works, because there are people reporting they tried using this way of charging and it’s quite okay. All in all, it seems to be a reliable product despite mixed reviews. Although the rating does not look impressive, the information stated in users’ messages does not suggest it’s an item of poor quality.

 

VIII. LEDGOO Handheld Solar Powered Flashlight with 4000mAh Backup Power Bank

This item has a sleek design and excellent reviews that enable us to add this item to the list as the finishing touch. The 120 lumens light can be used for continuous 34 hours (if you’re using the bright mode) of lighting, provided the battery is fully charged. There are three modes: the bright one, the super bright one, and the SOS mode. The built-in battery has the capacity of 4000 mAh, which means you can use it to charge your cell phone when it runs out of energy. The hook is designed to hang the torch on your backpack, and the anti-slip handle makes it convenient to use the flashlight.

Feedback summary

There are 21 reviews (as of October 2017), and all of them are positive and even seem to be real. There’s not much to say about the product, as it’s just a high quality torch which does what it’s supposed to do. Its users report that it’s lightweight and quite efficient. The average impression is nice, so it’s a product which can be recommended. The only thing we’d like to note here is that some review authors were granted a complementary item/discount in exchange for a review, though it does not mean what they state is not true.
