Sodium Hypochlorite Generator Multi-Purpose Cleaning Supplies Generator, Chlorine Testing Strips Included

This product is pretty solid. The weak point is that it would have been nicer to have more detailed instructions, like a table indicating the process and the resultant strengths, but you can do that work yourself with some test strips and a little google. Get yourself chlorine test strips so you know how strong your final solution is.Following the given instructions gives you about 200ppm, which is enough to make a good bleach disinfectant spray for cleaning hard surfaces.Give it more salt and a longer processing time, you should be able to get a solution up to 1% or so, which approaches strong enough to use as bleach. You'll probably need to use 2-3x as much to get the same result as commercial store-bought bleach, but that's not a problem because this amount costs you less than a penny.Although the cost savings could be huge if you're a person who uses a lot of bleach, the biggest plus here is that the bleach solution you get through this electrolysis process will be much safer than anything you buy at the store. Commercial bleach is stabilized with caustic lye, tends to be pretty nasty stuff. Make no mistake, this is chlorine, but the product you make with this process will not be considered "hazardous", unlike store-bought bleach. Also unlike the harsher chemicals in commercial bleach products, these are completely safe for the environment. What you make will decay back into ordinary salt water within a couple weeks.As a side benefit, you can also use this device to make Hypochlorous Acid, with the small addition of an acid to the process. Something like citric acid is best, but you can also get a decent result with acetic (vinegar) acid. This is useful as both a disinfectant and an antiseptic for topical purposes; and also is something that could be sprayed on fresh produce before rinsing to harmlessly disinfect any surface microbes.All in all, this device, while inexpensive, offers very high value for the price, as long as the person using it is willing to do a little bit of research to ensure they're using it safely and effectively.

I was skeptical that it would really work, but the strong scent of chlorine and the change in my chlorine test strips tell me that it's working. I have been filling a jar with about 12 oz of water and adding 3 of the included spoons of salt. After 30 min of electrolysis, the solution is > 250 PPM.The device is really easy to use and only takes a minute or two to setup. Using my own home made disinfect not only saves money but is also satisfying for the chemistry nerd in me. 😉

So far, so good. This is a review in progress...The goal is to generate a whole gallon of useful disinfecting chlorine bleach; sodium hypochlorite (NaClO), at a concentration of at least 0.5~1.0% (5~10 g/L; 5,000~10,000 ppm). Hopefully, I can achieve even higher concentrations.First, My A.I. buddy Grok recommends a sodium solution (salt content) of 19–38 g/L, which translates to 4~8 tbsp per gallon, or 1/4 to 1/2 cup of table salt, non-iodized if available. I will be experimenting with 1/4 cup, 3/8 cup, and 1/2 cup of salt per gallon of warm water in my experimentation.I have received my first USB chlorine electrolysis generator in the mail today, and so far it is working well. I have ordered a second unit, as well as a magnetic stir plate, stir bars, which should be ariving in the next couple days. The generator is only pulling 0.5~0.6 Ampres of current with the 1/4 cup solution, and to speed things along I really might as well buy a second unit. The stir bar will help keep the very fine bubbles suspended in the water for longer (3 to 10 times as long) to really absorb into solution, drastically reducing the time to achieve final product.I am running the USB generators on a battery backup powerbank rather than plugged directly into a wall charger, as it is absolutely forbidden to plug any electrical device submerged into water into a wall outlet. Watch youtube videos for USB wall chargers catching on fire, creating an electrical fire in your home, and electrifying the water you are working with. This is because most USB chargers reference to ground, and not properly isolated floating voltage, which encourages electrical arc and short circuit. It happens a lot. So, a battery bank should be used. I will be using a battery bank with (2) USB type-A ports.Until I receive the rest of my order, this concludes my my review in progress.

Update: Increasing to 4-stars.This hypochlorous generator is very good for producing larger quantities of HOCl than other small generators, but there are a couple of important tips:1) use warm (not hot, and definitely not cold) water to dissolve the salt completely before inserting the generator. If you do not completely dissolve the salt in the water before inserting the generator, you will end up with very weak HOCl solution and your solution will leave salt on whatever surface you apply it to once the liquid evaporates.2) MOST IMPORTANT: Once you place the generator into the saline water, give it a good stir so the water circulates. This helps saline water enter the openings on the generator and significantly speeds up the production of HOCl. If you do not stir the water to circulate the saline water, it takes a lot longer for the generator to produce the HOCl.3) The instructions do not specify how much salt to add to water. Based on a different HOCl generator I have, the ideal ratio is approximately 3 1/4 Tbsp of salt for 1 liter (approximately 1 quart) of water.This is an excellent price for this device.The only reasons I am not giving this device 5 stars is that the instructions do not specify a ratio of salt to water, nor do the directions recommend using warm water to dissolve the salt.

Work great! I love this device simple easy to make your own DIY cleaners and sanitizers! And saves a boat load of money !!
