- How does the iWata rechargeable USB fan stack up against the generics? Is it worth the extra money?
Buy Online: www.lazada.com....
At P385, the iWata USB fan is one of the most expensive on the market. But is that a bad thing? With a 12 month warranty, additional safety features, an 11 hour runtime and the peace of mind that comes from buying a branded item, many would say it's worth the extra money.
After testing the CM15RHF-02 fan from iWata for around a week, I've been quite impressed. It has an impressive air flow considering how low power it is. I don't know if it's due to the high efficiency PCB, the unusual fan blade design or the fan motor itself, or a combination of them all. But whatever it is, it works!
With a 1A charging input, you won't have to wait all night before you can hit the streets again with your fan. It also features a unique safety feature wherein it will pause charging the battery and only draw enough power for the fan itself, if you turn it on while charging.
Personally I'd rather be able to charge the fan and use it at the same time, but I know many people will appreciate this additional safety feature.
The supplied USB charge cable is acceptable but not great.

buy digital anemometer it measures air flow in standard units .
+Kedar Nimbalkar yeah the reason why I was trying to think of another option is because I want to measure overall air flow and not just the max speed in a single spot. But with multiple spot measurements and some averaging , it would probably provide a clear enough comparison between different fans.
Seriously this is an awesome review! I bought two of these, 1 is for my dog cage and one is for me because it is getting insanely hot in the country! I truly found this video helpful because I wanted a quality fan and this is definitely worth every penny. It just extends the life of the battery and I'm relieved that this will not blow up unlike the other cheap ones out there. Mine runs for only 8 hours in the lowest setting though but still, I'm not complaining. 😂Thank you so much!😊
Thanks for the kind feedback and I'm glad you're happy with the performance of the fan. I've been using mine every day since it arrived and it's still going strong :D
Gadget Addict hopefully mine does too! I'm torned between this one or the Cdr king one because both runs for a really long time but since this is your favorite and I really trust your opinion, I've chosen this one and I'm very happy with it. 😊 Does your Cdr fan still work perfectly?
My CDRKING fans are also still working perfectly. I've tested many fans and the iWata has the best airflow and that's why it's my favorite. But what I don't like about the iWata is that the battery doesn't charge while the fan is running. Ultimately iWata is one of the best out there in terms of materials used and the battery itself. But the CDRKING ones are pretty decent too.
Gadget Addict Haha well I dont mind that at all and its still a great buy😊 Thanks again and keep making informative videos! And I love what you said about "Behind every great man is a great fan."😂😂😂 i live for it hahahaha
More gadget reviews, please! I miss these kind of videos :D
I have one of those cheap fans that looks like this. I wasn't impressed by the battery so I replaced it with an 18650 from a battery pack of a Lenovo notebook.
It came on for like 5 seconds, then it burned. :)
Yikes, scary. I guess the problem with all the fans basically looking the same is that people assume they're the same on the inside and that the one selling for $2 is the same as the one selling for $8. I'm actually tempted to go on the hunt for some of the super cheap fans and see just how dangerous they are!
Great Review. I have a generic fan that I bought on ebay. When my sneakers get wet after a rainstorm, I put the fan upside down inside my sneaker to dry out.
That's a creative use :P It really is useful having a little fan that you can just put anywhere!
Great review man! and I also like the decor on the backdrop :D
Thanks! :) I was worried that perhaps the wooden #GA was a little overkill. I'll probably continue to use them but not so 'in your face' next time.
Ah nice!
oh you got a review of this. i bought two fans to replace my weak laptop cooling pad.
If paying more for a safer and more efficient gadget is my thing, yes it is worth the price. If I am after a gadget that is disposable for me, it is not worth the price.
which do you think is better, the one from ace hardware, cd-r king or this one?
It runs for 11 h :O it beats the dual battery fan
nice, i could use one. You should consider joining Lazada affiliate program and Amazon too.
Try using an anemometer to measure the fan speed
Bought one from Lazada after being thoroughly convinced of your review, and it finally arrived today. I'm loving it so far. Thank you Gadget Addict! Makes me wish Lazada has affiliate codes so you could make some more money from your great reviews :)
+Kazu Kishida I'm glad you're happy with it! Lazada do have an affiliate scheme :) but I don't use it.
Oh, any reason you don't like using it? Genuinely curious.
I'll continue watching your videos as support then :)
+Kazu Kishida not sure really. Maybe one day I will :)
can you make a review of iwata portable clip fan? Thank you
To measure airflow, u can use a winspeed meter
I also plug to power bank running non stop for 2 half days without 18650 battery.
Can you review this mini rechargeable fan jr-5580?
I got this so I can use it to cool down my ONU and Router and for 24/7 operation, it only last about 6months or so. Mines already failed due to bearing issue, the fan doesnt spin freely anymore. The fan is set to #1 when I use it.
I guess im back with standard CDRKING USB fan (literally USB fans not the usual portable rechargeable usb fans) and that last about 2 years now without having the motor failed.
Really? I've been using mine every day for at least 8 hours and it's still going strong. Why don't you get it replaced under warranty?
I already sent one but the RMA is rejected because I abused it (24hours operation for more than 6 months), I dont know how they can tell that but yeah, sayonara RMA.
+remle ikawura do you have a copy of that? I'd like to question it with my contact at iWata. That doesn't seem fair.
Hello, how to know if your Iwata fan's battery is already full?
Can you use it without a battery while connected to a power bank?
+Jovz Salla yes, you can :)
+Jovz Salla yes, you can :)
how does it compare at low speed for the 2 batteries fan?
Do you mean in terms of air flow? This iWata fan still has the best airflow of every fan I've tested, on all settings.
GA
Get 1 pingpong ball, 1 protractor, 1 short length of cotton thread
Hang pingping ball in front of the fan at a set distance
Using protractor measure disrortion of thread from vertical with fan at each speed setting
This will give you a relative measurement only
I will leave it to other subscribers to provide an equation to calculate an absolute energy value 😝
Sibat
Awesome, thanks for the suggestion :) One concern I have is that I might get similar results with varying sizes of fans. That's why I was hoping to find a way to measure the overall airflow rather than maximum speed or maximum power in a single spot.
You could multiply the angle by the surface area of the fan to get a total air flow value
Even if you buy an anemometer you will still only get the same sort of measurment just more accurate and as an absolute value
I love your diy videos so this rather crude mechanisms seemed to fit in with those segments
Btw i dont know if you follow 'blind owl outdoors' but i sent him a link to your pocket wifi signal booster as he lives way out in the province in bohol and can rarely get a signal at his house, i am hoping he will build one and try it out on youtube. It should be an extreme test, especially for the tranmit signal
Of course if you want to get realy accurate measure at various points in front of the fan and average the deviation angle 😋 Then multiply by the surface are. Ok this is getting too nerdy now so i will shut up😀😋😃
True, you raise some good suggestions, thank you! I just subbed to Blind Owl now. Thanks for sharing my video with him. I'll be keeping an eye on his channel! It could really make a big difference for him! :)
how long does the iWata last on it's lowest speed
11 hours 8 minutes in my test :)
Gadget Addict soo it has the same as the CD R KING Dual battery fan 11 hours that is soo awesome well here comes summer i will start to use fans like this
I use mine most days :)
Gadget Addict what fan this one?
I use the blue iWata and the green dual battery cdrking. I mix between them. I don't have any others right now :)
I will get one but on color red is it worth it to buy iWata or CD R KING one?
Both are good :) The iWata one has a better blade design in my opinion.
Gadget Addict it might be cool to use and i quite getting a bit bored with the same blade design's
Hi thank you for very informative videos/reviews.. can you help me please to look for a wearable cooling fan like blö.. TIA 😊
Replace to 3500 mAh battery it make big difference much longer hours...
can i use it while charging?
You can, but it will simply power the fan directly by USB and won't charge the battery at the same time.
hello :) which is better the iwata fan or the cdr king fan? hope you answer thank you :)
The iWata fan gives the best airflow but it does not charge and run at the same time which is very annoying.
Which do you think is better, this iwata or the ace one? im planing to buy one so it will help if you can tell me.
They're all pretty similar but I guess the iWata one has grown to be my most used fan, because it has such a strong air stream while consuming little power, so I get good battery life out of it. I think you'd be happy with either fan though :)
Ok thanks for replying. I guess i will go with iwata then. By d way you have a nice channel. I like your reviews very much. Keep it up!
I was looking around on your videos man bud - looking around for a USB Mini Fan for my router to cool it off cuz it overheats specially at daytime (specially now since its summertime).
Can I use this to cool my router off for a length of time? What I mean is - have you stress-tested it enough to consider it being safe enough to run say - 18 to 24h or even more since it'll be a cooling fan for my router? Wouldn't there be like short circuiting problems or overheating problems on the fan itself?
and again Nice Videos. Nice Reviews. Really like it :) Please reply as soon as possible - quite urgent XD
Any chance I can order this from the UK?
Gadget addict, Theres a saying that: "You get what you pay for". We have to invest more on quality.
How long does it last on the highest speed? '-'
Try to use Sound Tool (SPL Sound Meter) app!
For what purpose, measuring the noise of the fan?
Gadget Addict it actually did help when i was in the mall recording the noise if the fan! And it goes like 87 or 82dB!
can i use it while charging or do i have to remove the battery if i want to use my portable fan while using the charger
+_Technophyle you can use it while plugged in and you don't need to remove the battery. If you turn on the fan while plugged into USB, it will stop charging.
ohhh ok thanks for the fast reply!
Greetings, First thing I'd like to say I find all your videos informative. I have read this videos thread. but I'd like to ask is this a brushless motor. is this ok versus the one of cdr king nice one.
how to know if the battery is full when charging?
+Yhan-Yhan Yu the charge light will turn green :)
thanks!
I wonder where we can buy one :)
You can find them on Lazada and in National Book Store inside the mall. I think they might also be in some hardware stores :)
after fully charging the fan mine always flashes the 3 led lights when not in use, is it normal?
Mine only flashes when the battery is low. I'm not sure why you'd see it when it's fully charged. Does it seem to operate without any problem?
yes it is still working fine, but mine only operates about 6hrs at lowest setting after full charged. it only bother's me that it flashes 3 low light even it is not in use, also i notice that when the led light is on the 3 led light indicator also lights up.
Can you replace the 18650 battery with another one? I have two USB fans and I cannot replace the batteries that came with the unit with the 18650s I use for my flashlights.
I've used other 18650 cells with the fan and not had any problems. Including a larger capacity 3300 mAh (allegedly) cell. The maximum current drawn during charging is still under 1A, it simply takes longer to charge. Why were you not able to replace the battery in your other fans? They're not removable?
Excellent. I will definitely be picking one up, probably more. I did not see on it on Amazon (US site). I will continue to look around.
If anyone knows of a US distributor, please let me know.
Thanks for posting the video and keep up the great work. I really like your channel. I cannot tell you the number of items I have purchased because of your reviews.
Awesome, thank you for the nice feedback :) I'm not sure which exact locations they sell in, but I'll try check :)
Gadget Addict Sorry, I just saw this now. In the two fans I own, BenGoo and another fan with no company id, but it has a model number F95B. When I tried several of the 18650s I have, at least 10, they were too long. I would have cracked the housing if I forced them in. I was using Thrunite, OLight, Orbtronic, and other Panasonic cell batteries. mAhs ranged ferom 2800 - 3400.
MonGo WonGo Ah okay. I guess they didn't account for the longer 18650 cells which include the protection circuit which makes them longer. This one has a huge spring so it can easily handle the longer batteries :)
Iwata is made in japan
I bought so many mini fans already becoz after using it a couple of times ayaw n gumana.
What seems to be the problem.tagal k na nga icharge eh ayaw p din.
Which brand are you buying? Or where are you buying them?
Same feeling then my family will say that " you already have so many fans why will you buy another one!?!" I told them a lot of times that the fans are broken
Very interesting!
good information
that's really low power draw at low speed!
Yeah, I was quite surprised. Although it did explain how it managed to run for 11 hours :p
i thing you could use a portable anemometer to measure air speed or airflow. lazada has them. hehehe...
Yeah I was thinking about that. But that might show one fan to be faster than the other but the actual amount of air it's moving could still be less. For example a tiny but fast moving fan blade vs. a slower but larger fan blade. So I think my target should be to measure the overall amount of air being moved. That's why I was trying to fill up plastic bags with air and time how long it took. But it's hard to get a good air tight seal to make it an accurate test.
how about hooking a pvc pipe on the fan and on the plastic bag? just a crazy idea though. hehehe...
asi146 Yeah it might work, if I could somehow match the PVC to the fan size and create a good seal. It's similar to my original idea, just needs some tweaking. Thank you :)
how about cardboard roll? just a thought though. hehehe
i will get one around this week or next week
Nice! I hope you enjoy it :) It's getting hot hot hot!
Gadget Addict exactly i will just wait for it to arrive this summer :P and i will be getting a fan from Amazon too but it will be brought on April
Gadget Addict i was gonna buy fans from CD R KING which one does last the CD R KING branded or the Snowflake one?
They're both pretty good although I get a longer runtime on the iWata version.
How about on all of your USB fan collection
im fix the iwata portable fan
#GA
mini version of Iwata..hehehe
iwata? terrible support. Never buying thier products ever again.
Really? what happened?
well found thier email. sent them my issue. Product was a fan with the fog thing. when turned on it would fog but no wind (blades not moving). Told them its out of warrantly and looking for repairs. Took them a while to respond asked me where i purchased. then a few more days. I followed up. I was finally forwared to technical support. Then same round of questions. Thru slow response email. I answered.. then they finally stop responding. Well i gave up.
If paying more for a safer and more efficient gadget is my thing, yes it is worth the price. If I am after a gadget that is disposable for me, it is not worth the price.
