xasla 10000mAh Portable Rechargeable Clip on Fan, 8 inch Battery Operated Fan, 24 Hours Work Time, 4 Speeds Personal Fan, Ideal for Outdoor Camping Golf Cart Home Office Blue

Bought these to help ventilate a boat cabin in the Mediterranean. Very quiet so sleep not disturbed and lasts for at least 2 nights (on slow speed - which is all you need) before requiring recharging. Can move around to wherever it is needed too!

I play drums on stage , Just clip onto a stand and away we go.. Very pleased with the product.

Fan seems fine but was advertised as having 5 blades not 3. This makes is a different product which is also available on amazon and eBay cheaper

La pila dura mucho, el ruido es bajo y la cantidad de aire ayuda a refrescarBuen producto

I was very suspicious ref its claimed 10,000mah battery capacity. (**see UPDATE) Either the battery has the capacity they claim or the fan mechanism is unbelievably efficient.Test results: Very impressive!LOW speed: 16+ hours runtimeMEDIUM speed: 10 hours runtimeHIGH speed: 4 hours runtimeNOTE: The fan's drive circuit worked beautifully. The fan shut OFF completely (did not slowly wind down in speed). When the battery got low enough it did not drain the battery excessively or to its detriment. Shortly after the fan shut OFF I momentarily restarted it on LOW and it ran perfectly and at the same speed which the fully-charged fan ran on LOW... again, indicating the speeds are digitally set and the internal protective circuitry performed perfectly. Nice design.I have measured neither the exact current drains (at each speed) nor examined the battery cell(s) but I intend to and will investigate the ease of modifying to install additional battery capacity. (This is not because its design configuration is insufficient at all - it's not - but strictly because I'm an engineer and engineers tinker and tweak.) Will update the posting if I do.Fan noise: Extremely quiet and couldn't be happier with it! Remember, you can't expect to move a decent amount of air with such small fan blades without generating at least some noise. IMHO it moves an incredible amount of air for its size and with minimal noise in the process. Again, impressive.Weight: Is it light weight? - you bet! That's why I was extremely reluctant to believe the battery capacity and runtimes advertised.Spring clamp mechanism: VERY strong! It takes two hands to compress the spring to clamp it onto something. That's a good thing. Therefore, it should stay put when you clamp it to something. Having both azimuth and elevation adjustments on the fan is a very good design.Appearance: Very minimalist-style design, which also works well to promote excellent/efficient movement of air. The cross-grid appearance between the lines of the front and rear cases also reminds you of a Moire' pattern. Nice to look at.Thumbs up on this fan in every aspect.**UPDATE: I recently took a look at the batteries inside. Though the batteries were shrink-wrapped and I could not see the specific ratings, I could see that there are indeed (3) three 18650 cells, which are more than likely at least 3,000 mah cells, which would bring the entire battery pack up to at least 9,000 mah...which is close enough to the 10,000 mah rating they specify for the fan. Good for them!There was no room to easily add any more 18650 cells to the assembly, though as the fan ages and its performance eventually declines, I may indeed either swap out the cells for newer ones and/or add additional cells to the side of the internal case.Again, the fan operates incredibly well in its stock/original form and there's no reason for anyone to need to tinker to improve its performance. Nice design!

The fan feels solid, and despite its size it moved a lot of air.I had been looking for a fan to clip/sit on my treadmill and this is the answer, I run for 30 minutes to 1 hour daily and after a month of using this fan mostly on the lowest setting, it is still above 60% battery.This fan is small enough for me to move it around the house, sometimes after a treadmill session I would simply pick it up and bring it over to the dining room table.Overall I am happy with this purchase, my favorite thing about this fan is the long battery life.

Es una gran opción para cuando se va la luz en tu ciudad. La última vez se ocupó en un lapso de 5 horas en velocidad media y aún tenía el 80% de carga, es un gran producto y ventila muy bien.
