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:	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

• Fans are measured by the full size of their blade span (also called blade sweep), which is the diameter of the circle that you see when the fan blades are in motion. Or, in other words, fan blade span reaches from the tip of one fan blade to the tip of the blade directly across. As such, a 10" fan is actually larger than 10" when it includes the outer casing.
