COMLIFE F170 Clip On Stroller Fan, Mini Portable Desk Fan with Auto Oscillation, 4400mAh Battery Operated Fan, Aroma Diffuser Function, Stepless Speeds Control

Update 6-25-2020:The fan could not be turned on due to the dial being stuck in place. My belief is that they used some type of lubricant that becomes gummy over time. I had to work to get the know off. I cleaned the knob and the edges of the recess where the knob fit. I then used oil to lubricate the knob and recess. The fan can now be turn on and off. However, the fan no longer oscillates. I assume that part was damaged by the same issue with the knob: lubricant became sticky over time.I came here to re-order the fan. I will take the newest fan apart and remove their lubricant with some of my own. The oscillation was not a big deal for me, but it would be nice that this does not happen again, the sticking. My original is still on my desk keeping me cool as I type this reviewEdited. original title: This MIGHT be a great fan, Batteries are not lasting more than 4 hours.8-5-19, upgraded from 3-stars, to 5-stars!I originally ran this fan at full speed with the oscillation engaged. The fan does stay powered at that setting for 4 hours max. That seemed too short of a time. However, the amount of air being blown at that setting is asking a lot of this fan. It does put out an airflow that can be felt and is effective to 8 feet!At 3/4 setting the fan is still effective to 6 feet just lower air flow. At half speed, 3 feet away the airflow is lower but still being felt.Most generic fans have very poor propeller design. For patent reasons or simply cheap construction, most are junk. This little fan is very good.I ran this thing all night at about 1/4 to 1/2 speed and it was still running in the morning, about 7 hours!My major concern was over the ability of the charging system to safely and effectively charge and prevent over discharge of the 18650 batteries. When it is charging, red light flashes and goes steady when full. The 2,200 mAh 18650 unprotected batteries took about 4 hours to fully charge. The fan base did not get warm to the touch after I left the charging cable attached for a couple of extra hours to check on the chargers ability to stop when actually full. Cheap chargers will keep on trying to fill the battery and that is where you can get into trouble with unprotected batteries and cheap chargers.The noise level at full speed is what you would expect for a good fan of this size. Not too loud but not whisper quiet. At 3/4 speed the sound is what I would call quiet. 1/4 speed (3-ft away) the fan is almost silent! It is whisper loud.I will continue to test this fan. If it keeps working, I will invest a higher capacity unprotected 18650 batteries.---------end of update=====This could be the best small fan available. I rated it low on purpose due to battery charge control or possible lack thereof.=============================================================================================This fan is very versatile and puts out a lot of air for its size, way more than you would expect from a battery operated, small fan. The ability to stand it on a flat surface or to clip it to something using the built in clip that is the base is great design, The fan itself swivels pretty much in any direction. It is mounted on to what is a gimbal that allows the air to be directed in any direction without physically moving the fan base.It has a dial instead of buttons for the speed control which is fantastic! Infinite variability of fan speed should allow for longer battery life than the standard hi/low, or the hi.med/low setting found on most of these fans.The fan also oscillates (swivels) in about a120 degree total angle. The field angle can be changed by physically rotating the fan housing. Just press a button to activate/deactivate the oscillating function.----------PROBLEM: the batteries are UNPROTECTED 18650 batteries that after the first use, did not last more than 3 hours! Ran it the first time for 6 hours at highest setting and then turned it off to get a full charge and then to test how long it would last.The unprotected batteries mean that the fans internal charging circuitry and built in charging controls must prevent the batteries from becoming over discharged and also to prevent over charging, both of which will damage the battery. Over charging the 18650 batteries can cause a fire and explosion in some cases. No where in the MEAGER instructions does it explain how the charging is handled.----------I will keep testing this fan and monitoring the charging. The charging blinks when charging and steady red when the batteries are full. That is encouraging as far as charge control is concerned.If the batteries last at least 6 hours or more on average, and the batteries do not explode or catch fire (LOL) then this fan is a bargain even at its current price. Good quality 18650 batteries are not cheap retail. If this fan continues to work and the built in charge/discharge controller is shutting down the battery before damage occurs, then I will invest in better, higher capacity unprotected 18650 batteries.I will upgrade the rating to 5-star if the batteries hold a charge and do not explode. I am serious about the dangers of unprotected batteries being used without proper charge/discharge control. Google it.

I love that the speed is completely adjustable and not 1 through 3 or 5 speeds. I love that it's quiet. I love that it's totally rotatable in any direction and you can oscillate it or not. I love that it has a rechargeable battery so you can use it plugged in or not. I love that you can clip it on to something or stand it up. I'm not sure that they could do anything else to this fan to make it better.

I purchased this 3 years ago and still works. I used it for my newborn because we live in an island and sometimes it gets really hot outside. Now he is 3 and still works wonderful

Just what I’ve been looking for. 1 charge lasted several nights. Well made and fairly quiet. Love the fact that you can set it to oscillate!

The first one lasted me 3 years before breaking after a fall (it had survived many falls prior). After ordering the same one, I slightly different model arrived. After 6 weeks, it no longer holds a charge.

This fan gets full marks in every category. I first bought one of these fans for my daughter to use at secondary school (I live in the Caribbean), because from birth, when her skin gets hot, it gets irritated and itchy. A fan had to follow her throughout primary and secondary school, but each time it was a standing fan. Traveling with it was out of the question once it got to the classroom. This one worked out very well for her because it was very easy to travel with in her school bag, it's powerful and the battery lasted long enough until the end of the school day. I realised recently that I could benefit from having my own because I started borrowing my daughter's. I use mine throughout the night now that it's so warm, and the battery lasts until morning and beyond, once fully charged. My brother also purchased one and can't stop talking about how powerful it is for a small fan. This is indeed an excellent purchase!!!!

My old plugin fan that i used on trips burned out while looking for replacement came a crossed this. I like it can run off USB power which always carry wall plug for phone, USB power pack or rechargeable batteries 2 included. This fan is small doesn't take up much room and its base either stands on flat surface or can be clipped onto something. It has variable speed dial and oscillations switch with full fan directional adjustments. Now big question "does this fan put out air" oh yeah, lot more than my older fan did which was over double the size. You can be quite a few feet away and still feel the fan, pretty impressive indeed. This fan has a lot of features that stands out from others making it the perfect choice for a portable multiple powered fully functional fan.UPDATE: i ran it half speed from 8 am no oscillations and it spud out between 5 - 6 pm. Funny part is when i reduced speed to lowest it ran for 10 more minutes. I did charge it night before so 40 hour claim 🤔, maybe the battries need full charging couple of times. Still impressive fanUpdated: Using it now working out great and it worked great on the auto train i would not travel without one. I didn't think the oscillation was big deal but again it came in handy on the train covering both seats blowing more than enough cooling breeze with very little nose. I would recommend carrying a retractable USB cord and wall plug for charging. So many uses worth having

I like the fan ‘coz of its function. I can bring around with no problem and it’s very useful when am working. A great buy indeed.

Excellent portable fan that I use on my pram and seems so much stronger than other baby fans though not as cute as baby fans but that doesn't bother me. It's perfect for the heat in Darwin

Perfect fan for baby pram
