If you need a small table fan at your workplace or study desk, or you tend to work with your laptop at outdoor café and nice to have some cooling breeze, perhaps you can consider this Ooree UF108 8 inch USB table fan.
This USB table fan is good enough to generate breezing wind that you can feel within 1 meter in front of it, yet its size (8 inch diameter end-to-end) and weight (416 gram) are also good enough for it to be portable.
It is powered by USB source, which can be the USB port of your laptop / desktop / monitor, or the USB charging port of your power bank / charging adapter. By powering it with a mobile electricity source such as power bank, you can use it anytime and anywhere, such as during camping, during electricity blackout, etc. The fan has a low power consumption of around 2.5W only.
Its 1.2 meter USB cable is detachable. It has an on/off switch behind too.
It will have some noise of fan rotating during operation, but overall still considered pretty quiet.
Note that the 8 inch as advertised is the diameter of its metal frame. The diameter of its fan blade is around 5.5 inch only. Its build is pretty solid, despite its packaging box is hollow inside (without any foam or paper support) which does not provide much protection to the fan during delivery.
As you can see, its packaging box deformed during the courier process, which is the main complaint I have with this product. Luckily the fan is not too fragile and still in good condition during unboxing.
Its price is quite reasonable. If you search around carefully, you can find online seller selling it at less than RM20, despite most of the sellers are putting a price tag of RM30-RM40 to it.
There is another model UF110 which is 10 inch and with double speed control, selling at a higher price. If you need stronger wind, you can probably look into the UF110 model.
