GONGTIAN USB Mini Fan, Portable 4 Inch USB Fan Hands-Free Hanging Fan Powered by Rechargeable Battery with 3-Level Speed for Outdoor Like Running Camping Hiking (White)

This is a well-engineered product that provides a lot of air at a low weight. I measured the battery draw at the different settings as High = 1540 mA, Medium = 960 mA, and Low = 470 mA. The bundled battery is of high quality and is close to its 2200 mAh rating. 3400 mAh replacement batteries are widely available and will extend the fans run time proportionally to the ratio of the mAh ratings. You can determine this fan's run time, for any battery capacity and setting, by dividing the 2200 battery mAh rating by the actual mA draw at one of the 3 settings. For example, the bundled 2200 mAh battery, on the High setting, it will run approximately 2200/1540 = 1.4 hours vs the 2-hr. specification. With a 3400 mAh battery, on the High setting, it will run approximately 3400/1540 = 2.2 hours.Body contours are different and for me I needed to add a segment of foam to the back of the fan to optimize the air flow angle to my face. This product is the best I have found for keeping me cool while doing cardio exercise in an outdoors or gym environment.

Love this fan! It's awkward to wear while working (bending lifting) but click it on when you stop for a min. Blows quite a bit of air and is rechargeable!! (Tho I don't run mine all day so not sure on battery time) Great for hot flashes too!! I have also dropped it on hard floors and concrete at least 4 times and it's still working great. The lanyard broke where it hooks to the fan but I'm trying heavyweight thread now if that goes I'll try fishing line next! Great wearable fan for the $! I purchased a back up for me and one for a nice man I work with. Will buy again!! (If I need to!!) It's worth it!!

Another winner from Gongtian fan. I have a real Gongtian F95B and I enjoyed its strong wind and portability. However, my girlfriend wanted one that she doesn’t need to hold the fan while walking under the sun, so she got this model instead. It came with a neck lanyard that hang on to her chest and the fresh wind will blow straight up to her neck, jaw and cheeks. It will lower her body temperature outdoor on a hot summer day. After using it for a while, she did complain about the noise level because when it is at level 3, it is quite loud. Also, she felt the weight on her neck after 30 mins of use, so she needed to take a break to release the tension from the lanyard. It is not designed for indoor use, but the noise is acceptable at level 2 and level 1 indoor.I tried it myself when I was sleeping on my recliner and simply put the fan on my belly and let it do its job. It is a neat and creative design. I like the fact that I can put it flat on my body while sleeping. It cooled me down and put me on sleepy mode quickly.I actually found another surprise way to use this fan. I put the lanyard on my shoulder, and let the fan blow to my armpit. It feels very good when you are wearing tank top or sleeveless T-shirt. Rotate left to right and right to left when the weight is the problem. As always, I checked all the Gongtian authenticity. It passed all the tests and it is a genuine Gongtian fan.

The fan worked great at first. I have to wear a mask for 8 hours a day and this fan makes it bearable. I like that it has 3 speeds but I can’t use the highest speed because the battery will die within 2 hours of my shift. I’ve noticed if it bumps against something slightly it’ll cut completely off. It’s starting to make a rattling sound now but does still work. It’s made to where it blows at an angle and not directly up. Overall, it gets the job the done. I wouldn’t recommend because I don’t think it is worth the price I paid. Maybe if it were a little cheaper. Everyone I work with has some type of fan around their neck and most work the same or better and were under $10.00.

Helps me with my hot flashes goes with me wherever i go love it

It's so powerful, I was able to take a nap outside in 90° weather with just this fan blowing on my face. I had it on full blast for about 5 hours before I recharged it.

Es un maravillosa la cantidad de aire que genera.Le doy 2 etrellas porque el ruido es desesperante en lugares cerrados y hasta en lugares abiertos.No lo devuelvo porque no tengo con quien enviarlo y soy una anciana sola.Compré otro de correa, pero éste me vuelve loca.

Good idea but not too effective. Better than nothing though. I got a couple others that were much more powerful but slightly larger. Kept this due to laziness and not wanting To look for another one that could be worn around the neck and would be so portable.

Great fan keeps you cool

例年より暑い北海道、暑がりの息子に携帯扇風機1台購入しました。届いてすぐ付属品電池を入れて充電しないで使ってみたら、今まで買ったのより軽くて、丈夫そうで、使いやすそうでした、今度こそいい買い物したと思いました。
