TUNISE Portable Handheld Fan, Portable Fan Rechargeable, 4000mAh, 180° Adjustable, 6 Speed Wind, Display Electricity in Real Time, USB Rechargeable Foldable Fan, Quiet Personal Fan with Power Bank

work almost 12 hours in one charge—my little girl is using it in school.

La mejor compra que he hecho. Salva vidas en el calor!! Es cómodo, ligero, gran potencia (6 velocidades) y la carga de la batería dura bastante. El único “pero” es que tarda aproximadamente 4hrs en cargarse.

For me, this is the best portable fan on the market. 6 speeds, light and easy to handle, keeps a charge for a VERY long time. You can bend it back and place it on a table too. It's easy to see how much charge is left, and I believe that you can even use it as a charge bank (there is a USB A slot on the side).I've bought it for my wife, and every one of her friends has asked her where she got it from!Highly recommended!!

Works well. Liked it but not robust. After having had it for a month I dropped it from the height of my sofa arm rest (<3ft) and one of the fan blade broke off. So now it now vibrates (noisy!!) and it rotates on its own!!!Not sure if the fan blades can be replaced.

I was skeptical of its battery life and the force of the fan. I was surprised about both aspects. The fan is quite powerful. In my tent, I mostly use it on lvl 2 (out of 6). After an hour or two of laying in my sleepingbag + a full night of sleep, I usually wake up to a fan with between 35% and 50% of battery life. Exactly what I needed. I'll buy it again if I ever break it. I use it for moto camping and it's a game changer for hot nights out in the wild
