User questions & answers

The battery holder then gets placed back into the unit. If you have any other questions please do not hesitate to contact our consumer relations team by emailing us at [email protected]. Thank you.
Question:	Would this be good to use in a tent at an art fair all day long
Answer:	Thank you for your inquiry. If the car is off, this unit will not be able to draw power from the battery. If the car is running, this unit will still be drawing a small amount of power, but having the car idle for a while can kill the battery. If you have any other questions please do not hesitate to contact our consumer relations team by emailing us at [email protected]. Thank you.
Question:	What are the out side dimensions of this fan? Want to pack in a suitcase to take on a cruise
Answer:	Good question. This fan is fairly unobtrusive and may not be loud enough to create the white noise you are looking for. If you have any other questions please do not hesitate to contact our consumer relations team by emailing us at [email protected]. Thank you.
Question:	Can you use this continuously without the timer being on
Answer:	Yes, it is rather weak and does not oscillate. It will not disperse unpleasant odors. It is a personal-size fan--it only gives you a little air movement when things get stuffy or fetid : ).

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:	what is the length of fan blade measured from center of fan to furthest point on blade? measurements of the fan are conspicuously missing
Answer:	The filter needn't to be replaced
Question:	I was promised that i would get an amazon gift card is i reviewed this item and i never did. what should i do
Answer:	It seems like this is more time than necessary or the rugs/clothes are already heavily damaged by mold or smoke. Why not run it for 30 minutes to an hour and see how it affects the problem you are trying to treat? If those results aren't satisfactory then run it for longer. Ozone is oxygen on steroids, it oxidizes things. This means plastics/rubber/electrical insulation can get brittle, fabrics can weaken (tear easily) and colors could fade with excess exposure. There is a point where running it more won't likely improve the problem, ozone could trespass on neighboring property so a different solution is probably needed (like washing the clothes and shampooing or replacing the carpet)
Question:	Is there a trick to charging this/ I’ve left in on the charger for over 24 hours and then it will only run for 15-20 seconds
Answer:	Ozone is dangerous. However, plants are more resilient with ozone than creatures with lungs. Most plants excrete oxygen. However they do absorb it in the dark. So I run it if the mammals are outside, and it is Day outside.
Question:	Can you use the fan while you're charging it
Answer:	We provide 360 days warranty,if any problem feels free to cotact us.
