Review: Handy portable cooler - Super little gadget that I`m surprised hadn`t been made available a LONG time ago. I got this size for a specific cooling purpose, as it turns out it wasn`t needed but kept the fan anyway as it can be usd anywhere and for any reason. So useful - just plug it into any USB port or adapter and place wherever you need it. The rubber "all round" feet prevent vibration and movement, it can be used in any orientation and has 3 speeds + OFF altogether. Permanent or temporary placement - if you need something cooling, this is a very useful item to have. It`s reasonably quiet as well even on full - on low almost silent - at which I was a little surprised especially for the smaller 8cm size which can be a bit noisy. Cool a TV box, or portable hard drive, inside a PC for extra spot cooling, circulate the air in a cabinet.... you could even cool a hot pie off straight out of the oven if you wanted ! :)
Review: Great things come in small packages - a perfect little unit - I purchased this item to use with a WD 8TB My Cloud EX2 Personal Cloud Storage NAS with WD RED inside NAS drive as I was worried about the temperature readouts even whilst idle. On the medium setting it has reduced the temperature of the two drives inside by an impressive 20 degrees. At this level the fan is just about audible but the noise is low and, importantly, not annoying in any way as many fans are prone to be. The fan is suitably powered using just one of the USB ports from the back of the unit. The fan arrived well packaged, appears to be extremely professionally manufactured and initial impressions suggest it offers great value at the price I paid. Will update in the future if anything changes.

## Questions & Answers

**Q: can this be plugged into a mains via a phone charger?**
A: Providing it's a USB socket charger. But as always I wouldn't recommend very cheap sockets

**Q: Could this be used to cool a motorhome fridge freeze**
A: It dissipates heat and keeps heat-generating devices cooler, like games consoles, HiFis, BluRay players, etc. I don't think it would sufficiently cool a small fridge freezer though.

**Q: Hi! i need an uk adapter for that fan but can’t find it on the market. can you help?**
A: I use the fan as a cooler in my bedroom, with a 3pin usb plug. Other than that, I’m sorry I cannot help you.

**Q: Is the fan moisture resistant, could I use it to extract moist damp air?**
A: I don't think it's water resistant. I would think the ball bearings works rust quickly.

### ⭐⭐⭐⭐⭐ Handy portable cooler

### ⭐⭐⭐⭐⭐ Great things come in small packages - a perfect little unit

### ⭐⭐⭐⭐⭐ Not too bad
*by L***L on 30 August 2017*

I was actually a bit surprised by the quality of the item when I received it. I hadn't been expecting much since stuff like this is usually cheaply made but this is actually nice. The blade guards are metal, as is the central logo on each side. The rubber feet look like they will last and even act a but as suction cups on a flat surface. The lowest speed is more or less silent and the high speed is still fairly quiet. The thing even comes with a user manual. I'll also add that the controller stays relatively cool and the cable is nice and long. There is a USB extension for daisy chaining additional fans. It comes after the speed controller so those fans don't necessarily need a controller and, if they do have one, it won't be very useful. The blade guards and feet are removable, as one would expect.
