Koonie 10000mAh Portable Clip on Fan, 8 Inch Rechargeable Desk Fan, 360° Rotate & 4 Speeds USB Fans, Strong Airflow, Sturdy Clamp for Office Desk Golf Car Outdoor Travel Camping Tent Gym Treadmil

I don't normally rave about products, especially fans but this has been a gamechanger. I bought it to cool a small study and to take the edge of the humid UK summer nights, and it hasn't disappointed. Its a decent size at rough twice the blade length of the smaller hand-held ones. Its super-lightweight for its size as well and the strong clamp means you can attach it to pretty much anything, or leave it freestanding. I've had it on the headboard or the bedside table, and its a night and day difference in getting to sleep on hotter nights. The best thing is the battery life. Whereas the smaller handheld ones I have give up after an hour or so, I've run this continually on the low setting for 6-7 hours both overnight and even had enough juice to run it again during the day. Its very quiet on the lowest setting and always seems to have plenty of charge left thanks to the massive battery capacity, though I haven't used the higher speeds much. I'd say its well worth the money.The only potential negative is I can't see an easy way to take it apart for a battery replacement longer-term if it wears out, but there are phillips screws for the stand and motor casing, so it's probably possible.

We use these on our small boat cabin when its hot during the night, clipped onto the porthole curtain rails - so they are about 1M away from our heads. On the lowest setting, which is quite sufficient to keep us cool, they are virtually silent (minimal hum and no rattle) and use very little power so easily last several nights on a single charge. They are still pretty quiet on the higher settings, too. The clip is VERY strong but this does ensure they stay firmly fixed, even during the day when the boat is moving.I previously had some smaller, cheaper, clip-on fans which plugged directly into the 12V outlets but they were noisy (both hum and rattle), the clips were weak and for some reason (harmonic frequency, I guess) their vibrations resonated throughout the hull, making them even noisier.These are a bit more expensive but worth every additional penny.

My grandsons have a mid-sleeper bed with a large desk below. When it's Bern so hot their shared room has been unbearably HOT & they've struggled 2sleep. They were using a pedestal fan but that was just ineffective.This little beauty is USB chargeable and has a very strong clamp so can be placed anywhere. It can also stand by itself. The boys clamped it on the side of their bed and they were overwhelmed at how effective it was. At a simple touch you can change the speeds. Much quieter than our usual fans. You can also set it to tilt & turn itself. Blinding little gadget and also more compact than usual desktop fans. Wd highly recommend.UPDATE: I have now bought 5 of these - best money ive ever spent! I intend 2buy a couple more too! 👍

This Fan exceeded my expectations. The battery life is exceptionally, the output airflow is soo powerful on the highest Fan mode. It is lightweight and the grip is very strong, I sometimes use it on my racing sim frame to cool my wheelbase. Very easy to use, 4 airflow levels L,M,H,Automatic then off (5 clicks from On to Off). USB-C charging, takes a long time to charge from flat but it also last a long long time to drain the battery if used in low airflow mode. The Fan has a manual rotation/tilt of 360° all round. It is worth the money and would definitely buy again. Highly highly recommend.

Bought this for motorhome whilst travelling to keep dog more comfortable. Works a treat. Clip is very strong - had it clipped to side of my seat. Very quiet and moves air round well. Works better than cab aircon. Recommend.

Pleased with this fan , simple box , instructions on back of box so keep, fan and cable. The clip is so powerful I thought it was stuck together. In fact it is most excellent and will grab anything. Purchased for music events where playing in a band is difficult in heat waves. 3 lights indicate how charged up. Press the back button 3 times for the 3 different speeds and I believe it is quiet enough at low speed to play band charts such as Lil Darling without distracting other band players or for that matter sleeping with the fan on. The fan is a good size of about 8 inches . This fan is quite happy to be placed on the floor or clipped to any part of EG a music stand. Runs via its USB rechargeable battery but runs while connected also but check is safe to do so.

Bought this fan to use with my Peloton (Bike+)It clips onto the top of the monitor and can be permanently powered by USB-C feed on back on the monitor. I'd recommend a 50cm USB-C to USB-C cable (for the Bike+) which keeps it nice and tidy. With the mounting clip, I'd imagine it would also work on a Peloton Treadmill too.Whilst it claims 4 speeds, it has a low, medium, and high speed, then a Variable speed setting that automatically cycles thru the L/M/H speeds. The high speed is quite impressive from such a small fan and generates plenty of airflow.There are 3 very small LED's on the back that indicate charge remaining in the battery.Have only used it on battery once and it seemed to be quite efficient.A great little fan for exercise.

Rarely I find the drive to review something but these fans are spot on.The clip is very sturdy and strong and you can clip this fan to virtually anything. We used it in our campervan while driving and then at night while sleeping.The battery lasts ages and appears to charge while I'm use too.They move air at 3 speeds and everything is done with 1 button. And the spin tilt feature make them easy to point in any direction, and they stay put.Brilliant and simple.Not sure about the 24hr claim but from half charged we did about 7hrs driving so regardless they are adequate for any journey.
