I run a much larger wind turbine on my boat and it takes a surprising amount of wind and perfect alignment to produce any meaningful amount of electricity. Small portable wind turbines might develop into something more practical in time, but currently there isn’t anything on the market that really works.
The wind will always be diffused by objects on the ground. You'd be better off to get a pole you can screw together and bury into the ground, so you can raise it higher. The wind is moving faster the higher up you go.
Here's an idea, why don't you connect this to your handlebar as you're cycling from one place to another. It might provide enough wind to charge your phone up from a certain percentage to another. Would be interesting to see. You could also go to marina barrage where there are pretty strong winds, try putting it a bit higher up. Also, no harm in contacting the manufacturer. It might be a case where the device works but you unfortunately received a lemon. They might send out a replacement to try or give some advise, like lubricating some parts or other tips to get the most out of the item and maximise the charging.
A few guys have mentioned a similar idea too, as well as attaching it to the mast/rails of a boat (example). I tried attaching it to my bicycle handle-bat, but it was sorta in-the-way. LOL`
I get the impression this is all about location, location, location. Where I live, on the coast of Norway, a turbine like this would spin like mad hell 20 out of 24 hours. I have also learned from flying radio-controlled glider airplanes, that airflow moves along terrain in special ways. I'm sure it's possible to optimize placement of the propeller as you gain experience "reading the airflow". Especially if traversing high mountains, it is possible to find spots with constant strong winds. But if it needs 24mph winds to charge at all however, I'm not sure it would be enough even here. Bigger blades turning a more powerful dynamo is probably needed. Cool video. Normally I would say it's too long. But it's well edited and informative all the way, making it a very enjoyable watch. Cheers
Many thanks for dropping by! Yes, I do reckon you're right, that the location where this is set up is crucially important. Unfortunately for me, it will be hard to find such spots here in Singapore. That said, from some of the other advice/comments I've received, having this fitted onto a moving vehicle (eg: boat) could be a useful option as well. 🙂
I believe the location of where it is deployed matters most. Some advice I got from fellow RU-vidrs, was to have it attached to a boat while out at sea. 😊
They should design vertical type of that instead of propeller type. Vertical will spin easily even in low wind and it is more efficient of harvesting the wind energy.
Saw this in my recommended. All I can say is that it is kind of dodgy. It has no voltage regulator so it can be spinning really fast and generating too much voltage which can damage your phone’s charging circuits. If I was to get one I would get a voltage regulator circuit for it so It would have a constant 5 volt output no matter the how fast the turbine is spinning
The garden was really good. About the portable wind mill. Please fix it to the bicycle or two wheeler or a four wheeler. Just check while travelling. It may work.
Maybe if you created a small portable wind tunnel, that would solve the problem. I'm familiar with the Venturi Effect with rocket stoves, and that same principal works with liquid and air. That principal basically states that liquid/air will speed up when entering a smaller diameter. So if you created a 5ft (more or less) opening to your tunnel, then tapered the tunnel down to 3ft, the air would speed up when entering the 3ft section of the tube/tunnel. And at the end of the tunnel it would expand back to 5ft again, and that's where you would place your generator. You should theoretically get faster wind speeds at the end of your tunnel than at the beginning
Would be interesting to look inside the alternator, it certainly looks to be "cogging" meaning it's not an ironless generator which would start to spin a lot easier. ( might even be a motor they're using as a generator, which is never a good idea) , you said you could feel the vibration when you turned it round, which would seem to confirm this. It does however, look very well made,, and possibly just needs a strong wind. Can't really beat solar panels for charging phones, I used to charge my phone from my bike hub dynamo, but had to cycle about 40 miles to achieve the same result a 15w Anker solar panel gave in an hour ( in the sunny south of France) Great video, thankyou
Yup! Yup! You're absolutely right! Having it attached to a moving vehicle will certainly help with generating a constant power-supply. Especially for long-distance travels with little stops. 😊
it looks like a good start....but it needs a way to direct it's orientation(aka, a fin known as a rudder). aslo s lowever mass rotor/stator combo.you'd get less juice but it will spin easier
Good review. I am glad I watched this video. I know now to purchase one I really need to be beachfront, in strong wind, with a much taller tripod than what comes with the product. Meaning it comes with enough to get you started but not enough to make it functional. You have to invest more time and money to make it worthwhile.
Bro, I got good tip for u. Why don't u set this up in front of ur heavy duty industrial fan at home. Confirm will work. Otherwise can try under those big ass fans at the ccs or mrt stations. There's a saying in Sg. Use money to make money. You should use wind to make wind or rather use electricity to make electricity. That's called the full circle of nature, where nothing is wasted, yet everything is wasted. Vicious cycle. By the way, u got a sub. Keep exploring and enjoy the simple pleasures
Is a very cool wind turbine but my own suggestion is this, i think the wind blade is too small for it to catch more wind they need to expand the bade a little bit so that it can catches more wind .
YEAH! I think they did precisely that with their new model(s).. 👍🏻 For this version thst I got, the best recommendation I've received from viewers, is to have it attached to a mast while sailing, or to use it in extremely windy conditions.
Not free, there is no free lunch. You have to pedal harder with the resistance in turning the fan. Easier to just carry a portable battery. The make a front wheel hub that has a generator in it. It takes up to 6% of your pedalling power. Not much on a short ride, but on a long tour it is not worth it compared to a battery pack.
I'm late to the party, but this was a cool review. I live in an area where the wind is pretty strong a good amount of the time. Unfortunately, I also live in an area where it rains/snows 3-4 months out of the year, which I don't think would be good for the electronics part of the turbine... or my smaller electronics. Maybe, I can get some sort of shelter in conjunction with this to use it almost anywhere. 😊
Another option I've read in my comments, is to have it placed facing a fan (while you're actually using the fan - in summer), but it isn't something i've tried. 😊
@@Hong.Wanderlust I like that idea. I think I'm off my rocker because I would try to use the turbine off-grid in an emergency situation if I needed it that way. 😄
@@Hong.Wanderlust That's exactly what I was thinking. I'm going to purchase a fan and I thought well. I could probably place it in front of or perhaps buy one of those dual window fans that blow the air out and in.
You don't really need streams for water turbine. In Singapore it's always raining. If you put a water turbine in any longkang on a rainy day, can generate enough water to power a whole doll house
I have played with a couple of these, but until there is a breakthrough in turbine technology, small devices are just toys. Unless you live on a tall, windy mountain.
Maybe if you somehow got it "loosened" up a bit? Looks to me like it's a bit to "tight", loosening the connection between the turbine and the generator might/should make it spin easier, IE: Less resistance/friction... Cause out of the box it looks like it WANTS to stop
I did indeed try 'loosening it up' a little, but it still wasn't as smooth as I would've liked. Ultimately, I think the windspeeds were just too low (more like breeze-speeds). LOL!
Unfortunately drag from generator is too much for small blades for a dynamo like that you need bigger blades also wind is always much much stronger at height the pole provided should be a minimum of 4 metres .
wonder how that would work with vertical turbine? problem with horizontal turbines is the need to be high up vs vertical turbines working with less wind and closer to ground.
Your battery was probably too big. The bigger the battery, the bigger the resistance, the stronger the current has to be to affect the battery. The wind turbine might be good to charge a cell phone or a small powerbank.
It is a good product but the blades are mediocre and way to small. It would be working easily in low breeze wind if they were a lot larger. You could try to make them yourself. There are similar design out there that produce 30 or more Watts, so it might need some tweaking. Good try though.
Suggestion. I was watching you and I’m from the USA. We don’t use the metric system and when you write out speed or dimensions I see that you write it out in the metric system. Can you do the work ONCE for all your USA viewers and also write it in pounds, inches, miles etc.? If you don’t mind of course. It would help your viewers in the US.
lol, fyi normal voltage for USB is 5V. I haven't looked at the model u tested but their bigger one requires 24km/hr which is like ... go ride a scooter at that speed & you get the idea. I had high hopes when I saw that it was designed in sg. also fyi, the avg "micro" turbines that I've come across have base wind speeds of 12km/hr
Thanks for the info! Yeah, I saw a video of some guys attaching it to a sailboat, and that seemed to have worked really well. I guess it isn't the most effective tool to have for camping.
I don't have an accurate reading of the wind speeds, but i will reckon most of it were probably under 15km/h?? as per many of the comments, an ideal option will probably be (on a boat, bicycle, or even in front of another fan that is already in use). 😊
Unfortunately I haven't tried them out yet. I did write in to the manufacturers to ask if they were willing to loan me a set for a review, but sadly didn't receive any replies (yet). That said, I might consider purchasing a set myself in the future to test out.
Hi, i live near the coast where they have placed windmills at sea and i have see the windmills getting bigger every year, because the higher they get the more wind they catch. For the tex energy one its bit high price
That's awesome, to be living near lotsa windmills.. Unfortunately for us here in Singapore, it isn't a viable option. Having said that, we aren't without options, with solar power being the preferred choice for renewable-energy.. I saw online that 'Tex Energy' recently released a newer version (INFINITE AIR 18), but it doesn't seem to be available for sale here (yet).
Agreed! It'll make long-distance trips more practical. However, I'm not too sure if there are any portable devices that can charge up an eBike, maybe portable solar panels? But then again, those that are powerful enough might be too large for cycling/bike trips. 🤔🤔
Can you attach it to a solar panel powered trickle charger for a car so you can charge the car battery when it's windy and use the solar power when it's sunny out side
Is there a rectifier to convert the AC to DC built in to the battery or anything you had there? the output of all generators as far as I know is AC(Alternating Current) and to put it in the battery it needs to be converted to DC (Direct Current).
There's no real value with it unless it's a really windy day. Windier than average and then you can only charge a phone. Best bet is get a solar power bank to charge you're phone. It's more efficient
😂 😂 Indeed. But in its defense, I was told that is worked well for some who live (here in SG) in high-rise apartments with good winds. And also peeps who go sailing.
@@Hong.Wanderlust i used to do some sailing before covid, the problem with Singapore is the wind is intermittent.Good idea though. I use windfinder (free) to check wind conditions when I go sruf casting
Hello Jasmint - To be entirely honest, I am not sure, but I will assume that 8km/h ~ 10km/h may not be sufficient to really push the blades consistently.
@@madscientistme Depending on where you live, solar power may or may not be the best option. Here in Singapore (and most equitorial countries), we have PLENTY of sunlight, so solar works really well. ☀ I recently tested out some new portable solar panels from Nitecore, and I've been using them every few days since.

better to run 1 electric sate board wheel as a generator yes it will create drag but not as much as a wind generator with the losses of the blades and generator and bearings.
Nice video! I have one and even bought the Air 24. It does take some strong wind to use it. Mine unfortunately has pretty much locked up and all I have used it for is light testing. But it did produce energy. I also pressed down on the tripod to get it to stand in the sand and broke a part that holds the leg down. So be careful with the tripod. My thoughts are that it would be good for attaching to a boat, mountain climbing, or extremely windy and consistent winds. Check out my unboxing of the infinite air 24 if you would like. Take care! Aloha
Hello! Yeah, I think you're absolutely right, this product will work exceptionally well if used out at sea or camping in mountainous/windy spots! Will definitely take a look at your video too! Thanks for dropping by! 😊
@@elieltanr I think it might depend on where you live? Here in Singapore, it seems like we only have the 'AIR 5' and 'AIR 18' available. - www.texenergy.com/collections/portable-wind-turbines
Yeah! I saw some videos of guys attaching it to a sailboat while out at sea, and I think that's a brilliant idea of ensuring constant and consistent winds.
let say i want to power my 100W monitor for one hour, and lets say you could store the turbine power in batterie. With 3.2V and 0.2A you generate about 0.64Wh that is 156hours of charging to run 100W appliance for one hour. I am noob, and i could be wrong. But this is not really good
Hello! I'm a noob with such things too! 😅 But you're right, unfortunately this product may not be very suitable for most applications (personal opinion), unless you're in a REALLY suitable location (mountain) or constantly in the move (boat).
Unfortunately you did not have a strong enough wind to overcome the resistance of the turbine. A body in motion tends to remain in motion unless acted upon by an outside force. Same for a body at rest, stays at rest unless acted upon by an outside force. Your turbine was at rest and wouldmanufacturer's ,
