Great Travel Fan

I am a proud Fan addict. Can’t sleep without one. And never travel without one. This fan was a game changer on a long haul flight from the west coast to the UK. It provided such a nice breeze and didn’t disturb anyone around me. It was easy to travel with and super quiet. I really like that it tells you the battery level and that it is completely dark(no lights on) when it is on and unplugged. Battery life is long enough for a good 10-12 hours. I have yet to have it quit on me, and it is fairly quick to charge.

Life saver

Ordered this to take on cruises as cabins tend to run warm. Didn’t get to use it until recently. This thing was a life saver. While it doesn’t have magnets, I used a magnetic hook on the ceiling to hang.

The charge lasted 8 hours (overnight) with still enough power to keep running. I would charge it daily and use it nightly. It was quiet yet powerful. Would definitely recommend on or two. Be sure to get some magnetic hooks to hang it though.

Amazing! Worked better than expected.

This item saved me while traveling in Europe in August. Even though I purposely reserved hotel rooms that advertised air conditioning, the heat wave with temps over 100 caused ACs to struggle and in some cases, it was not working at all. This fan allowed me to get some sleep! It is compact, has five power settings that actually work, and it runs on battery or plug in. The battery lasted all night (8 hours) on one charge, and I even used it to charge my phone one the train. You must carry it in your carry-on luggage because it has a lithium rechargeable battery and cannot be in checked luggage. It is small enough that it isn’t a problem.

Battery Caught on Fire

Fan was bought on July 17th. On August 24th the fan stopped working and proceeded to smoke a lot. The battery inside proceeded to catch on fire and spew gray smoke!

CAREFUL, AS OF AUG 2026, PRONE TO CATCHING FIRE.

. .

LOVE this!

Amazing!!! This thing puts out air even on 1 (and there are 4 settings). Really good at keeping a charge. It can go all night long and we still have a charge in the morning. I had a smaller version of this, but this makes a huge difference. Have no complaints. We have bought more since this purchase as it's great for a nightstand or even a desk!

BEST Purchase!!!!!

I bought 5; one for each member of our family for our vacation in Paris for 4 weeks. It was SO HOT during our stay and no AC. These little fans gave us a break from the heat while we slept. But the best part was that because they’re USB powered, mine came with me everywhere….while walking, in a taxi, on the metro, while out at restaurants, in every part of our apartment!!!

I highly recommend this fan… worth every penny!!

Amazing value for a powerful fan!

This thing was the little engine that could. I had a work trip into the hottest week of the year in Maryland and this fan literally saved my life. My hotel AC was barely functioning all week, but this fan was a trooper. This fan was just enough airflow to make my family comfortable all week. I would definitely recommend this fan to everyone.

Great Portable Fan!

This fan is just Awesome!

I cannot believe how powerful it is.

We took it on our cruise and it was perfect and it’s very compact. Definitely recommend

The best portable fan I have ever seen. I just threw out all of my other small fans.

Such an upgrade over my old desk fan. Love this thing. Fully rechargeable, no wires and you can charge devices from it. Four speeds, really quiet and great breeze. I'm taking this everywhere with me during the Arizona Summers. Thank you!

Pretty decent fan

Light portable adequate power. However, the power indicator sometimes is not accurate. I charged it overnight, it's still showing 73%. Sometimes stuck at 69%. Today it's showing 100%. I tested the power reserve and have the fan on for 8hrs straight, power indicator showing at 48%. I'd say it's pretty good, however I am returning it and upgrade it to the 20k mah and 8 inch version, not satisfied with the fan speed.

AVOID THIS... DANGEROUS! Would have been perfect if it lasted

I loved it at first, but I had it less than 2 months. I only used it during two power outages, and the battery is already warping the fan case. It's obviously not safe to use any more. And you have to pay to get rid of it.

I'm very disappointed that it didn't last, because it was exactly what I needed. I hope it's just a fluke because I bought it for camping and never got to camp with it.

Great product!

Love this! We will be taking it on a cruise with us but for right now I use it next to my recliner to keep any mosquitoes that got in our house off me. It’s also great to use outside if the summer insects are a bother too!

Excited to make this work.

I have a RuffLand crate that needed a flat fan. This was perfect for the Subaru outback and be able to bring down the hatch.

This deserves 6 stars

I bought this small light weight fan did an 8 day Celebrity cruise. This more than did the job. Last night I used it for 8 hours

I'm currently in Miami airport and the battery is only at 55%. It's extremely quiet, fully cools an area dnbuses very little charge. This is a keeper.

Great battery life

We bought a second one after testing it out. We got for when we go on a cruise as we are use to a ceiling fan blowing on us. It has four speeds. I gave it a full charge and it will last ten hours on high speed. The next night I used it on low speed and woke up to 71% battery left. Has 4 speeds. Worth the money IMHO as it packs easy.

Must have fan

This portable fan is the perfect size—small enough to easily pack for trips, but powerful enough to give great airflow. The battery life is solid and lasts through the night, which is a huge plus for me. I like a cool environment when I sleep, and this fan definitely delivers. It’s quickly become a must-have that I’ll be bringing on every trip with me!

BEST TRAVEL COMPANION!

I LOVE, LOVE, LOVE this fan! I use it for when I travel, which is several times a year. It fits perfectly in my luggage without taking up much space since it lies flat. I need a fan for when I sleep or am putting on makeup, and this is the absolute best one I've found. I've brought it on cruises, road trips, and anytime I'm traveling away from home. The charge lasts a long time and I love that it has multiple settings! I know I can use it to charge my phone or other things, but I really haven't had to do that yet since I always travel with an extra charging cord and brick as well. I highly recommend this fan. It really is the best travel companion out there.

Wow-great air flow

Arrived in a slender box with a charging cord & mini screwdriver. Battery was at 62%. Power levels 1-4. Right now in the video it’s a level 4. This will be great while traveling. It’s perfect for work as it can easily fit into a purse or BOGG bag. The thickness is that of a notebook/journal.

Workhorse

I purchased this portable wireless fan on Sept. 8, 2025. My WiFi router gets warm to the tough due to cramped spaces so if purchased the Warmco fan and placed it behind the WiFi unit.

Report:

1) Quiet

2) Connected to USB for charging

3) 24/7

4) battery works too

5) Reliable 100%

6) Price right

I sometimes shut it when shutdown desktop PC . However, there are times I forget the fan is on.

If your fan has issues, the Warmco may be your solution.

Warmco has a unit with remote. I probably will acquire it for the vanity area. Perhaps even provide a video of the product.

Cool cruise cabin

What a great way to stay cool and have some air flow in a cruise cabin. This fan worked great with a light fan noise. We had an interior cabin and the AC unit vent was on the ceiling above the bed. To maximum the best way for both of us to stay cool I used 3 magnetic hooks to hang the fan from the ceiling in front of the AC vent. I could have only used 2 hooks but the 3rd hook in the center kept the fan in place. The fan ran for approximately 7-8 hours on level 2 fan speed out of 4. At 100% battery it went down to 50% battery life.

We chose level 2 because it was good enough for our comfort level. The handle stay in position on an angle all night long without any issues. The fan packs up easy and provided us with some much needed sleep on the cruise.

Great Fan - Misses the mark for cruising - see comparison

This review is for the Warmco 10000mAh Portable Desk/Travel Fan model D3. The fan was protectively wrapped in a plastic bag which was then inside a cardboard retail package, along with the charging cable and a mini screwdriver.

The product description lists this fan as 1.6"D x 7"W x 8.4"H and it’s hard to measure exactly, but it seems accurate. In comparison to its bigger brother with the 20,000 mAh battery, this fan is easier to hold/carry around, and it weighs less than a pound at 14.1 oz. It takes a little over 4 hours to go from zero to a full charge. There is only 1 button to operate this fan which works for both the power and to select from the 4 fan speeds, so it is simple to use. The digital display is easy to read and cycles through the fan speeds before switching over to continually show the battery level as it’s running, which I totally love!. While plugged in, the battery level blinks until it reaches 100, and the fan will also work simultaneously if so desired, The front detachable grill is held in place by 2 small screws, which are easily removed with the included screwdriver, and affords access to clean the fins and such. The stand has rubber feet, and moves to adjust the angle that it sits at, plus it rotates 180 degrees to double as a hanger. It is a little tough to pull the stand out when it’s snapped closed, and for me the difficulty in this design makes it less desirable than some of the other fans.

I tested this fan against a few others shown in my photo to check the battery life and compare features. The other fans I tested were the Warmco 20,000 mAh, the MaGolfin 12,000 mAh, and the Amacool 10,000 mAh. I have already written my review on the Warmco 20000, and plan to write reviews on the other 2 fans, so you can seek those products out for further details.

This fan has a 5 fin design and is relatively quiet; like most fans, the higher the speed, the more noise it generates. Unfortunately, the battery life stated in the item description is not accurate. My tests showed that on level 4 (high) this fan ran for 10.5 hours which was actually a half hour more than stated. The issue with the battery life surfaces when testing levels 3 and below. On level 3, this fan lasted 13 hours 20 minutes, which is almost 2 hours less than the stated 15 hours. Level 2 produced even worse results lasting less than 8 hours when it was expected to run for 19 hours. Thus, this battery ran for 11 hours less than advertised, which to me is a big difference! This seems strange since on high it lasts even longer, but I can only report what I witnessed. I chose not to test level 1, and cannot confirm the run time for this level.

My everyday fan that I’m using at home is from Warmco, and I’ve been pleased with it. At this point, I’m seeking a smaller fan to take on an upcoming cruise with me, and I thought this looked like a viable option. The item description for this fan says it is a “Cruise Cabin Essential” but it has some downsides that make it not 100% ideal for me. The biggest and most obvious is that it is lacking a magnet which would allow it to secure to the cabin walls, ceiling, etc. The 2nd thing it’s missing is a night light, which would be helpful for finding my way to the restroom without waking others in the room. The final thing that is not a deal breaker, but more of a bonus feature that’s nice to have, would be a built in timer function, which this fan doesn’t offer. That being said, this fan was not advertised as having these features, so I won’t deduct any stars for the lack of these things, but given the poor battery performance, I have deducted a star.

Although this fan is a handy size, and will run throughout the night, I have selected a different fan for my trip that offers a strong magnet, a nightlight, and easily rotates 720 degrees. Happy Cruising!

Great little rechargeable fan!

Love this little fan! With a full charge it will run for a long time. It is very quiet and moves a lot of air for its size. I purchased a second one for my son at college to have on his nightstand. The arm of the fan can swing up so you could hang it as well if you had a hook. (See video) The entire fan lays flat so you could pack it in a suitcase / tote or closet easily. They also have a fan with a light. Would and have purchased again.

Compact, Excellent Value with Digital Battery Display and Four Settings

I had a different 10000 mAh USB-C Fan which had four settings for both the fan and lights, along with a 2H, 4H, and 6H run-time selector. The only issue with it was that when I traveled on an Airplane, it was somewhat cumbersome. I was always using it so I was physically holding it and then placing it on the Airplane tray. When driving or in the office, this was not a problem.

The Warmco 10000 mAh Portable Fan (7-inch) is a more compact fan without a clamp but a foldable hook that can serve as both a holder (for camping) and a leaning item for desktop or vehicle use. Just like the pictures on the website, it will fit in an airline or vehicle chair pocket and can be slipped next to a tablet or a laptop when not in use.

One Positive is that it has a simple button that can cycle through the four levels and a digital display that shows the percentage of battery remaining. Level 1 and 2 are quiet enough for office use in a cubicle w/o intruding on others.

There are only two negatives - one, the fan does not have a USB-A or USB-C out to charge another device. This is not a problem for me because I was aware of this prior to purchase and will not dock points for it - though others may find that a sticking point.

Two, the fan does not have a light - again this is not an issue b/c the 20,000 mAh version has a light (10-Inch) and I was aware of this prior to purchasing. The Compactness was more important to me that the under 100 lumens light it could have come with.

One final thing to note . . . if the temperature is < 90 degrees, the fan works perfectly. Between 90 and 100 degrees, it is cool but the air is clearly warm (especially if you are typing in a vehicle with the AC off. Over 100 degrees, and the fan is simply blowing hot air - it is not an air conditioner.

I would purchase again for the price and from the seller. It is a good value in the modern age with a USB-C recharging capacity which works with power banks (in the field) and obviously AC in the office, vehicle, or home.

Decent fan for the price, only one concern.

Great little fan, my only concern is that, being that it's brand new, it seems the power button sometimes doesn't work as expected. I will keep an eye on it and return if necessary. I've always gotten it to power on, but I have to fiddle with it sometimes to get it to work. Battery life is good, even on the highest setting, gets between 8-9 hrs, and at the lowest setting, around 16 hrs. Takes about 3-5 hrs to charge.

Sturdy compact little fan

This is, by far, the best purchase I’ve ever made. I’m currently going through menopause and was traveling to California. I’m very dependent on having a fan to make it through the night. This fan ran continuously throughout the night without needing to be charged. It’s TSA-approved, so I was able to take it on my carry-on. I absolutely love this purchase.

FAN-tastic!

Wow! This WARMCO Portable Fan is so COOL, no pun intended! Wanted it for blowing smoke away from the other guests at our picnic table and it works great. But I have found even better ways, like by my head at bedtime for that comfort noise even though it's pretty quiet and at the beach. We are taking it on our cruise this summer since it's so compact.

The chargeable fan lasts a long time (10 hours for me today) and has a digital screen that lets you know the battery life. You can prop it up with the built-on stand or hang it. Air flow with four speeds that hardly make a sound even at the highest speed and a super great feature is the front panel is removable so you can clean it!!! I don't like the fans you can't clean as they build up so much ugly dirt and dust. This company also includes a screwdriver and extra screws in case you lose one.

KUDO's to WARMCO for an awesome fan!

Surprising wind power for a little guy!

This is a pretty nifty little fan! It has 4 different speeds that are displayed on the little button. It also displays how much time you have left in percentages. If you have used half of the battery it will read 50%. The seller’s ad says it can run 24 hours on full charge and I assume that is on low speed…but I am not sure. I have not tested that claim yet. I am surprised at how much air this fan can blow, it is surprisingly strong for a 7” fan. The kick stand can take on many positions; all the way upright to all the way down. It is rechargeable and comes with a USB to C cord. You supply the charging block. When I was filming the fan I didn’t even have it all the way up and when I turned it around so you could see the back it blew over the box I had set up that it came in. That shows you how much wind force it has!

Cool, Quiet, and Convenient: The Perfect Travel and Office Fan!

I never realized how much I needed a portable fan until I got this one. As an office cubicle dweller, finding a fan that is powerful but also quiet is essential, and this mini fan fits the bill perfectly. It’s so quiet, I can run it during my conference calls without worrying about disturbing my colleagues. The best part is that it’s portable, so I can easily toss it in my laptop bag or carry-on for travel. In fact, it’s become my go-to for hotel room stays, where I use it on the nightstand to keep cool for a peaceful sleep. With USB-C charging, I don’t have to worry about running out of power, and in a pinch, I can even use it to charge my phone. I absolutely love this thing.

The 10000mAh battery in this fan is a game-changer. It lasts up to 24 hours on a full charge, depending on the speed setting, and I’ve found it works great at any of the four speed settings. The fan's 5-blade design provides a nice, cool breeze without the noise that usually comes with a powerful fan. It’s perfect for use at home, in the office, or even outdoors. The fan's slim and compact design makes it easy to carry and store, and the foldable stand means I can store it flat when I need to pack it away. Plus, the digital display makes it easy to check the current speed and battery life, so there’s no guessing when it’s time to recharge.

This fan doesn’t just keep me cool – it’s also practical, thanks to the USB-C charging feature. I can charge my fan and phone at the same time, which is especially handy when I’m on the go. The combination of quiet operation, portability, and long battery life makes it a must-have for anyone who needs a little extra coolness wherever they are.

Great compact fan for desk or travel

This is an ideal ultra-thin desk or travel fan, exactly as described and pictured. The 180° stand rotates easily into any position within its range and folds flat for compact travel or storage. The fan has four speeds and is rechargeable using the standard two-foot convertible USB/USB-c to USB-c cable included. The finish is a good-looking matte black plastic and the blades are translucent plastic. Also included is a mini screwdriver along with two replacement screws, so that the front panel can be removed for cleaning. This is a very well thought out product. Worth its price.

Awesome desk fan!!

Super duper good quality fan with 4 speeds. Very quiet and cordless fan uses a usb to charge it. Fan is the perfect size and blows out cool air. Definitely worth the cost. I was going to give this to my brother but after trying it out. It’s a no go. I’m keeping it.
