Question: hi, this fan specification 110Volt, can use on 220V power socket?
Document: This compact fans packs a good amount of power in a small package. It is small enough to conveniently reposition it when you need to adjust the location of your circulating air. It works well in front of a window to bring in fresh air. I personally use it on the floor right above my air vent in both winter and summer to help to distribute the air circulation in my bedroom.
Good fan, decent power. We have it on almost constantly in our bedroom, and it's been working for months without issue. My one complaint is that I wish there was a 'medium' setting, as the fan only has two speed settings.
I wish it had 3 settings rather than 2, hi and low
I have been using this fan at work for the past two weeks and I must say it works fine. It does not make much noise during its operation and the two-speed setting help control the power and amount of airflow. Even at high speed it is relatively quiet and I can concentrate on my work and receive or make phone calls. It measures about 9 1/2" H X 6" D X 7 1/2" W, and it does not take too much space on my desk.
I adore any of threes Vornado fans! Great power, and really keeps me cool....I've used lots of fans, and this is the best so far
love this fan, circulates the air and gives a cool breezewe use in our small bathroom which great especially when I'm using my hair dryerI would definitely recommend to friends and I'm getting ready to buy a larger one
The only thing that keeps me from giving this fan a higher rating is the way that it is described. It is a very small fan an calling it a room air circulator seems a big exaggeration. That being said, it is quiet and well constructed and would make a good personal fan, which is what I use it for.
There are two fan speeds included as well as an off setting on the back of the unit, so you do not have to unplug it after use.It is a small unit, so it has its limitations, but that is also a big plus. A quality product too. Build quality is high. Recommended unit for a small room where you need to create some air movement.
:)It's a great little fan for personal use! I sit it on the table 12 inches from me - on low and it's just perfect. Plenty of air for me! The tilt on it didn't work initially. It wouldn't stay where I put, so I just tightened the little screws on the pivot and that fixed it. We had a larger Vornado for years until my son broke it. They are made very well.
This is very untrue in my opinion. I don't use the higher setting because it's way too loud in my opinion. The lower setting is okay but still not something I'd call whisper quiet. It's still louder than I like.Circulation- I wish there was a rotation feature on this fan. I don't really detect much air circulation outside of the fans direct path.
Answer: yes
