Koonie 10000mAh Portable Clip on Fan with LED Lantern and Hook, 8'' Battery Operated Desk Fan, Quiet Camping Fan with LED Digital Display, 360° Rotation & 3 Speeds for Travel Tent Gym Treadmill

The Koonie 10000mAh clip on fan has been a great addition to my workspace. The airflow is surprisingly strong for its size, and the clamp is powerful enough to hold the fan securely while also doubling as a stable stand when needed. The controls are intuitive, making it easy to switch between the four speeds, and the built‑in battery level indicator is a thoughtful touch that takes the guesswork out of charging. On its lowest setting, this fan sends out a pretty strong air current and is nearly silent. Easy to recharge with a USB-C cable. The battery lasts a long time too. I once left it on in my garage overnight, and when I came out the next day it was still running. Overall, it’s a well designed, versatile fan that performs better than expected.

Quick summary: this fan provides sufficient airflow for personal cooling (much more than most small USB or battery powered fans provide), in a compact package with good battery life and multiple charging options. The only flaw so far is that it is too easy to activate it accidentally. Full review: To set the context, heat is my enemy. I hate warm weather. I keep my house at 68F and I always have a fan running at my desk or beside my bed. So when planning a two week trip to Italy in the summertime I knew I would want to bring a fan with me. In the past I have used the small 4” diameter USB powered fans that are commonly sold on Amazon but the airflow is weak and they wear out and begin to rattle quickly. They also require a USB power source at all times. I also use a Ryobi portable jobsite site fan sometimes but it is too large and heavy to pack. The ideal portable fan should produce ample airflow, pack relatively flat, store enough power for a decent runtime, and be easy to charge. Durability and quiet operation are important factors as well. This fan (The oddly named Koonie) delivers on all counts. Airflow is excellent. Most of the time I have it on the medium setting. It is quiet, and more compact than I expected. The clip folds sideways making the whole fan about 3-4” thick when packed flat. It’s not exactly small but I had no trouble fitting it in a day pack when traveling. I haven’t tested the total battery life yet but after a couple of hours on a train it was still showing full charge (more on that later). It charges with both micro USB and USC-c, which is great. More importantly it will run while charging, so you can power it with a USB-c charger all night and then take it with you on a day trip first thing in the morning. The clip is quite effective and I’ve had no trouble attaching it to a variety of mounting points. I’ve included a photo of the fan clipped to the overhead luggage rack in an Italian train. Overall, this fan has checked all my requirements, and I sincerely wish I’d had this years ago. Nit Picking: - The button that activates the fan is flush with the back surface, and while it’s a perfectly nice, clicky button, it is easy to activate the fan when it’s packed in luggage or a backpack. I found it running on more than one occasion. I plan to put a layer of packing tape over the button to reduce accidental activations. - The battery life indicator is nice to have, but could stand to be more granular. It has four levels: 100%, 60%, 30% and nothing (all lights dead). Many fans have no charge indicator at all, so this is hardly a complaint worth mentioning. Other than that I can’t find anything to complain about. The build quality is higher than I expected and I don’t think it will break unless abused. I should note that I don’t know what sort of bearings it has, so longevity is uncertain. I also haven’t fully tested the max runtime. Other than that I can confidently recommend this to anyone who needs a portable, compact, battery powered fan. Update: I’ve had the fan for a year and a half now. It worked through my trip to Italy, and I’ve since taken it on a number of camping trips, replacing the Ryobi jobsite fan I used to bring. It lasts for many hours, and I’ll clip it to my cot and run it all night. I was in a wedding last summer, and I knew that being in a tux in the heat was not going to be awesome. I brought the fan along with the rest of my clothing and stuff for the day. I found I could easily clip it to places like the table I sat at during the rehearsal dinner and reception (I clipped it upside down, hanging below the table, aimed up at me from the side) and many other inconspicuous spots. It was quiet, discreet, and effective. Heat is my weakness, but this fan is my secrete weapon. I’m quite pleased with it. I’ve also run it for days on end at my desk. It is every bit as quiet and powerful as it was when I got it.

I honestly didn’t expect this little fan to be this good! It’s small, lightweight, and super easy to carry anywhere — perfect for work, travel. I got it for my baby who gets very hot easily and sweats while sleeping, an it been the best thing for him. We use it whenever we go out and it hot out. The battery lasts for hours on a single charge, and it’s surprisingly powerful for its size. It has multiple speed settings, so you can go from a soft breeze to a strong wind in seconds. And the best part? It’s quiet! You can use it while sleeping. The design is sleek, modern, and feels high-quality. If you’re thinking about it, stop thinking and get it! You’ll wonder how you ever lived without it. Highly recommended!

Purchased a couple of these for our flybridge on our 44ft Carver Yacht. Charges well and keeps a good charge. Have used a couple days at a time for 6-8 hrs and didn't need to recharge. Did not use on high, but low or med speed. Can be adjusted several ways for air movement. Clamps onto our bimini structure so can be moved all over. Has been a lifesaver in hot weather. It is quiet so you don't need to yell over it. Good power. Size is perfect to not take up much space. Very functional. Seems very durable. Highly recommend.

This fan is lightweight has 3 speeds and a clamp to attach to many different surfaces and conditions. The highest speed isn't too bad for the size of the fan. It charges by USB-C which is good. It says it has fast charging , but maybe my charging brick is too old for that as it took as long time to charge to 100%. It came 30% charged. It is a great option to have a personal fan that you can attach to headboard of bed, railing, counter top etc. The clamp is very strong. It's nice that it is cordless but it also works when charging which is good. UPDATE. This cordless fan is GREAT. Just what we needed. We took it down to a Caribbean vacation home and it comes in handy on hot days and nights. The fan is very quiet, but pretty powerful with 3 speeds. The clamp is VERY strong and I have been clamping it to a book shelf while sitting in a nearby chair and it’s quite refreshing. You can swivel the fan and bracket in many different directions . It holds a charge for hours.

These are awesome! We needed rechargeable fans to use aboard our trawler (i.e., yacht) when we're at anchor and operating the boat on the house battery bank instead of running the generator, and these fit the bill perfectly! They would also be handy in a lot of other settings. Clip them to your lawn chairs at the beach or use them to cool you in your recreational vehicle or fishing boat. They're so compact and flexible, they'll even be helpful at home around the patio or pool or in the garage or shed. Despite their small size, the fans put out a ton of air even on the LOW setting, and at that setting they run for over 24 hours before needing to recharge. With four different speed settings, the fans are versatile enough to be used in any space. And the strong clips we've found we can attach the fans to handholds, tables, chairs, and countertops as needed. We've used the fans almost 24-hours-a-day for a few months now, and they're still running like new.

This Koonie clip-on fan is exactly what I needed for RV trips. The 10,000mAh battery lasts a long time, and the airflow is surprisingly strong for a cordless fan. The clamp is sturdy and grips securely, whether on a shelf, table, or bed frame. The four speed settings give plenty of control, and it’s quiet enough to run at night. It’s lightweight, rechargeable, and super convenient for camping, travel, or using around the RV without dealing with cords. Great little fan that really delivers.

Powerful, quiet, portable, long lasting. I have had this for about 3 months and use it daily at home and while on the road in a hot bus while waiting for groups to get done on trips. It has not let me down, ever. My only complaint is it is very easy to turn on and I store it in my backpack frequently and it is almost always on when I go to grab it. I solved this with a small add on button cover for a PC, no big deal. I drop this, abuse it, and have had it in pieces all over my motorcoach and school bus and it always without fail goes back together and works fine. The clip is strong and useful but usually I just set it on a random surface. I love this fan.
