Community Reviews

This tiny USB desk fan is best for light cooling where portability and simple power matter. It has strong airflow for its size, works well on low or at the 3 of 5 setting, and can run from a phone charger or power bank. The compact body tilts easily and is quiet enough for sleep, though not silent, with a steady background hum. Its main appeal is the lack of a built in battery, which avoids battery wear and makes it easy to power anywhere.

Common Questions (5)

  • It is not silent, but it is described as a constant background hum rather than a jet-like noise. It can be slept with, and on lower settings it is reported as quiet but still powerful.

    CyanNest3122Warnerrrmegablank

  • It is described as having amazing airflow for a small fan and being powerful enough for desk use or sleep. One setup even uses it facing down on a bed top panel, and another report says it works well on low.

    TommyC3884Kheiri23megablank

  • No built-in battery is mentioned; it runs from USB power instead. That makes it usable from a phone charger or portable battery pack and avoids the dead-battery e-waste problem common in cheap rechargeable fans.

    LavenderPickle7682LavenderPickle7682

  • Yes. It can run from a phone charger or portable battery pack, and one report says it used about 2% of a 30,000 mAh power bank per hour on the 3/5 setting.

    LavenderPickle7682Warnerrr

  • It is very small and easy to tilt. The compact size makes it suitable for a desk, bed setup, or other light-duty cooling tasks.

Can any recommend an extremely quiet fan to use at my desk at the office where it can get a little hot, but I don't want to bother my neighbors?

for serious quiet, i would diy a fan by getting a usb to fan header cable (for a bit more these can come with a rheostat to control the rpm) then any case fan 120mm or 140mm, then any cheap bendy phone flip to hold it in position (no need to enclose it). just keep in mind that a usb-a to fan will deliver half the power a case fan can handle, so i'd go bigger and more rpm on the fan, because at half power it will be dead silent.

There's a few options out there with replaceable 18650 batteries. I much prefer them over these as they use a standard battery and only require me to bring one thing instead of two when we take them camping. I think mine was like 10 bucks on a Amazon deal.

https://www.amazon.com/efluky-3-S...B00Y1VZ00E

Example
If you read the reviews for the fan you linked, the battery is no longer replaceable -- the battery door is now a screwed-in compartment, and the battery is soldered to the circuit board. Saves like 10 cents, and makes more ewaste.

And before anyone says "just desolder it", be extremely EXTREMELY cautious when soldering around lithium batteries. They're firming in the class of "ruin your year" sort of mistakes.

Its just not economical to replace batteries on things this cheap. There are fewer sources of salvage cells anyways as laptops no longer use 18650s

It really isn't -- I prefer something that has a user-replaceable 18650 (protected button top version), but those devices are few and not all that inexpensive.

Anything with a non-replaceable battery (especially custom size batteries) is essentially ewaste. Hence why this posted fan is nice -- it's just a USB cable. Use whatever power source you want.
