User questions & answers

Question:	I still believe Opolar the Rpms is 2350 , 2750, 3400 not 1800,2100,2400 that’s incorrect why did you change the speeds
Answer:	It puts out a lot of air at low setting so I wouldn't worry about nitpicking RPM speeds. Also the fan hum is quiet at low and bearable at medium speeds.
Question:	Does the fan turn off after certain amount of time
Answer:	Dear Diana, Thanks for contacting OPOLAR. I am sorry that the fan will not turn off after certain amount of time. I hope it helps. Regards, OPOLAR Customer Service
Question:	How long does it last without plug in to power source
Answer:	There's no built-in rechargeable battery, but you can connect the fan to a rechargeable power bank. That will make it portable. I checked the fan's power consumption using a USB tester. At low speed, it consumed from 0.2-0.3 amps, at medium speed 0.45-0.55 amps and at high, between 0.85 and 1 amps. You can get a 5000mah power bank for around $10-15 and experiment how long the fan lasts at different speeds (higher fan speeds will run down the power bank faster).
Question:	Is it quiet enough to stream with
Answer:	I would say so. On low in a quiet room it is pretty quiet and you can feel air from more than a meter away. High has a little motor noise but still a bit less than an 18" pedestal fan. Medium is in between. The air flow is very directional, aiming it at your stomach gives low air flow to your face, which could help with any noise at your mic. Nice little fan.

User questions & answers

Question:	can you use regular batteries in the fan
Answer:	For me it charged at 0.68 amps for a little over 8hrs. Here's the full detail: Two 18650 2600mAh batteries shipped w/ my USB/18650 powered OPolar fan. I immediately used it on high for about 4hrs (keep in mind the product is shipped w/ undercharged batteries due to safety regulations) when it died. A digital multimeter showed both batteries at about 3.4v each. I then charged it w/ both batteries in the fan via a USB wall charger connected to a DROK USB multimeter. It steadily drew 0.68amps until the batteries were almost full and then started trickling down as the charge SLOWLY completed. The DROK also showed cumulative mAh during the charge process as 5272, which just about matches the combined capacity of both batteries (2600 mAh x 2) and proves they are good/new & can store their original intended capacity. Both batteries were very cool to the touch(very good sign that they were not hot at all and the charge rate was safe) then registered 4.2v on the multimeter The entire charging process took a little over 8hrs (A bit too long for my taste, so I'll be looking for a standalone charger that I think can safely charge these particular ICR(least safe 18650 chemistry but packs the most power) batteries at 1amp total, meaning 500mAh each), which makes sense because 5200mAh (combined capacity of both batteries) / 680mAh (0.68amps) = 7.7hrs
Question:	can i able to run the fan while charging with a power bank
Answer:	The USB/18650 battery powered fan comes with two (no extra) 18650 batteries and a USB cable., which can be used to plug into a power source for charging. No actual charger in the traditional sense (i.e. USB wall charger) is packaged with this product.
Question:	How do you know when the fan is fully charged? I see the red light while its charging but how do you know when the battery is fully charged
Answer:	Hello Amazon Customer, Thanks so much for your inquiry! There is a indicator light on the back of the fan. When the fan is fully charged, it will turn green from red. Pls notice that the battery will not be charged when the fan is working and the light will not turm on. If you have any other question, pls fell free to ask. Thanks, OPOLAR Customer Service
Question:	How strong is the clip, can it clip tightly to a baby stroller
Answer:	yes you can - that is how I run mine at work - with the power bank

User questions & answers

Question:	Are these powerful enough to keep me cool on a 100+F day
Answer:	I use this fan on my desk at work. At times the temp is in the mid 90’s. It is wonderful. Just remember to keep it charged.
Question:	should i have received a cord with my fan as well
Answer:	It only comes with a USB cord. If you ask me it not worth the price. I returned mine and got a Honeywell fan for cheaper and much better quality.
Question:	Hi, I am a very hot sleeper and looking for a fan for my night stand would this work for that? And keep me cool
Answer:	I don't think this would work for what you want - I have this on my desk and it's great for that - but I am very close to it - think the nightstand would be too far away - but a great lil fan
Question:	Can i charge this fan with my solar power bank
Answer:	If it has a USB port, I don't see why not? It takes a couple hours to charge from the wall outlet, so it might take longer if it's a small solar charger depending on how much power it's putting out. But if it has a battery brick, then it should charge just like any other USB device.

User questions & answers

Question:	How quiet is this at each different speed
Answer:	I use in my cubicle at work. Compared to other small fans I feel it is very quiet. I usually use at it's lowest speed.
Question:	can this fan be put into checked luggage on a commercial FAA airliner for international travel
Answer:	I'm sorry you can't put the fan into checked luggage on a commercial FAA airliner for international travel as it contains the Li-ion battery,but you can put into your carry- on baggage.
Question:	How many hours (or days?) does it last with battery when used every night when there's no electricity
Answer:	I have a similar model (clone version) made by OPOLAR. Average run time test results: LOW _ 12:09:13, MED _ 6:29:24, HIGH _ 2:59:29. Battery capacity test @ 500mA: 2326 mAh. I am planning on purchasing the Efluky model. I'm expecting to find the products to be identical, except for batteries. While I'm hoping that the battery will be at least as good as the OPOLAR, my more realistic expectations of the Efluky are as follows: LOW: 8 to 12 hours, MED: 4 to 6 hours, HIGH 2 to 3 hours. (If I remember, I'll come back and update this answer with the test results of the Efluky. )
Question:	Can you just leave this plugged in and not rely on the battery
Answer:	In my case, NO .. I'm not sure what all of the yes's are about but I have that exact fan and it does not run on USB alone.. There's a charge light, if it's plugged into USB with the battery, the charge light turns OFF when you turn it on and indeed the battery died about 4 hours later and it shut off. If I uninstall the battery and plug it directly into USB, it doesn't come on at all.. It charges fine, it's a powerful fan, loud.. but absolutely will not charge and run at the same time and absolutely will not run without the battery installed which is very unfortunate. It has nothing to do with my USB power either, I've tried it plugged into my desktop with USB 2.0 or USB 3.0 and it won't work, i tried it with an iPhone charging adapter ( USB to the wall ) .. nothing..

• Longer Operation and Rechargeable Power: The fan comes with high quality Lithium battery 3600mAh (included). Operation time upgraded is about 6-26 hours (Varies depending on the wind speed). It can be also used and recharged via USB port from computer, power bank, USB charger or other devices with USB output.
• Strong Airflow and 180° Rotation: The fan with 3 settings of the air flow speed can be adjusted among low, medium, high according to your demands. The fan can be rotated in 180 degrees so you can place it in multiple wind angle.
• Quietness: The fan boasts a quiet operation to keep you cool while making minimal noise so you can focus without any distractions. The minimum noise is close to 20dB, it keep quiet even on the highest fan speed.
• Compact and Portable: Easily carried in bag when you go out or travel and Perfect for office, home, dorm, camping, library use, etc.

User questions & answers

Question:	Can you access the inside of the fan to clean it
Answer:	If you want to clean it by prying the fan open, I wouldn’t recommend it cause it’s on there pretty tight but you can definitely work a Q-tip in there or even slide in a thin rag for a quick dusting.
Question:	Can I charge the fan at the same time as running it
Answer:	This Fan will work when it is charging. However, it charges slow and would effect the lifetime.
Question:	How long do it last when it fully charge
Answer:	For me, on a full charge, it ran for 20 hours at the lowest speed. (continuous).
