Compact, Powerful, and Long-Lasting Handheld Fan with Extra Features
Color: Pink
I took this little handheld fan to a concert in mid June last year and absolutely loved it. It is small, easy to carry, and holds a charge really well. I have probably used it for over 3 hours on both low and high speeds, and it is still going strong on a single charge.
I also really like that it doubles as a battery charger and a flashlight, which makes it super convenient to have on hand for different situations.
Another great feature is the safety design. The blades automatically stop if anything comes into contact with them, which is appreciated.
Overall, this is a great portable fan that I would definitely recommend, especially for concerts, travel, or hot days outside.

It’s a super good product! Compact but mighty!
Color: Brown
Don’t let the size of this fan fool you! It is powerful, great for a hot summer day, or if your car has no ac, it’s not only a fan it is a flashlight which is very bright, and the topper of all is it’s a phone charger!! For such a small item but packs quite the punch . It is small enough to fit in your purse, pocket or backpack! But don’t let the size fool you!

Perfect for Summer
Color: Pink
I ordered this portable fan for a trip to the Caribbean and it was perfect. It definitely kept me cool during the heat. It's small and lightweight and it has various settings for different levels of flow. It doesn't oscillate but that's fine with me. I've brought it with me on multiple trips so I'd say it's reliable and it has great power too. The blush pink color is so cute and feminine I love it!

Compact Fan That Actually Works Well
Color: Black
This ended up being a pretty solid little fan. The biggest strength is how compact and portable it is while still putting out a decent amount of airflow. Easy to throw in a bag, keep while traveling, or use outdoors without it feeling bulky.
Build quality feels decent for the price. The plastic body is lightweight but doesn’t feel especially cheap or fragile. It feels designed for portability first, which is exactly what I wanted.
One thing I did appreciate was that the blades don’t hurt if they accidentally hit your hand or finger. Small detail, but it makes the fan feel less annoying to use and probably safer around kids as well.
The flashlight feature is honestly whatever for me. Nice that it exists, but not something I personally needed or would buy it for. The fan itself is the real value here.
Pros
* Compact and easy to carry
* Good airflow for the size
* Lightweight but reasonably well made
* Fan blades are safe and don’t hurt on contact
* Convenient for travel or outdoor use
Cons
* Flashlight feature feels unnecessary
* Plastic construction is functional, not premium
* Not powerful enough to replace a larger fan
Final Thoughts
Overall, this is a very practical portable fan that does exactly what it’s supposed to do. Compact, effective, and easy to keep with you. The extra features aren’t a huge selling point for me, but the core fan functionality works well enough that I’d still recommend it.
Who It’s For
Great for travel, theme parks, outdoor events, sports games, commuting, or anyone wanting a compact personal fan that’s easy to carry around.

Great product

Fit in my purse and has a good battery life for as much as I use it. Enjoy that there’s two different air flows.
