It assures to be safer for the environment since it does not contain heavy metals like lead and mercury, eliminates improper disposal of batteries, and uses up all the juice of old and weak battery. The HydraLight claims to be a flashlight that requires no charge and no batteries, it runs purely on water.
How does HydraLight work?
Working on a type of battery called Galvanic Cell, HydraLight claims to have two different types of metals that are connected by a salt bridge and employs Redox reaction to light the flashlight. HydraLight asserts to use water as electrolytes that work as replacement of toxic chemicals found in traditional batteries.
Simply remove the hydra cell fuel cell and put it in water. When water enters the fuel cell, it begins to produce power. Then, place the fuel cell back in the HydraLight and its ready to use as a flashlight.
HydraLight produces continuous light up to 100 hours every time you charge it in water. Simply add more water and you can continue to use it for another 100 hours.
Flashlight powered by water – The DIY flashlight HydraLight convinces to use water to power up and to be more reliable than traditional flashlights that run out of power and never help when you’re stranded without light. You just need to fill HydraLight up with water and it powers up to illuminate the area that you need. HydraLight proclaims that it also makes for a good school science experiment. HydraLight maintains to be fun as a project no matter what one’s age. These claims of HydraLight will be verified when there are more user reviews to analyze. HydraLight guarantees that it runs for 30 minutes on regular tap water and up to 2 hours on salt water in spite of being a single cell prototype.
Environmentally friendly – HydraLight alleges that one wouldn’t have to buy batteries or even recharge them if the flashlight is used. HydraLight emphasizes that on adding an extra water-powered battery, triples its illumination and time. This type of battery also works on wall clock, calculators and radios. That sounds a bit farfetched for a flashlight; user reviews of HydraLight will certify the truth. The flashlight emphasizes to use the Joule Thief circuit that lights up the flashlight even if there is weak voltage, so it will always be handy and utilizes the last speck of juice of an old and drained battery. This asserts to make HydraLight more environmentally responsible. Whether or not HydraLight has such great features will be revealed by user reviews.

Unlike other fuel cell devices that are expensive the HydraLight is cost-effective.
Hydralight Flashlight Customer REVIEW
According to Warren Stone, a Hydralight Flashlight reviewer, it isn’t a device that literally runs on water, but is actually working on a metal electrode such as magnesium. He says that once the electrode is exhausted, no amount of water can make it work. He says in his review that there are many other similar flashlights such as Hydralight Flashlight and come at a cheaper price and marketed as a water activated flashlights, which is a more accurate representation.
Rosalie Garner’s Hydralight Flashlight review reveals that the flashlight is not at all cost-effective since there are many other cheaper and plausible options available in the market. She found that even battery-operated flashlights can be cost-effective since they can be recharged several times and used to achieve a powerful light.
As per Philip Lynch’s review of Hydralight Flashlight, it is a scam since it doesn’t really run on water but is activated by it. The number of hours that are mentioned by the manufacturer is nowhere true and even if they are, the flashlight will still not be cost-effective. He suggests other users go for a regular battery-operated flashlight that functions on battery and not gets lured into buying this scam of a flashlight.
