O2COOL Treva 10-Inch Portable Desktop Air Circulation Battery Fan, 2 Speed, Compact Folding & Tilt Design, with AC Adapter (Graphite)

This fan I took to a festival and it worked for 8 days on the same batteries. I had it on during the day to cool off and it ran all night as I slept. It can also plug into a wall to use as a regular fan. There are 2 settings, low and high. It's superb at what it's meant for. The plastic is very light because it's travel friendly. It will click into place at several angles. It's best for a 10'x10' space or smaller. you won't feel the air any further than that. Now that I no longer camp, it's 6 years later and I take it with me around the house. It saves on energy bills to cool me off in one room, rather than run the entire house's A/C. Some days there just is no airflow otherwise.This is delicate. You cannot drop it onto the ground or it will crack. There is a singular wire in the back, and you can easily disconnect it if you are just manhandling it. act as though it is a phone without a case on, and it will be a great tool for you.This is NOT for big rooms or large gatherings. This is a multifunctional camping fan, best for a tent or a small room like an office.I've used this for 6 years and it's still going. Almost none of my other electronics last that long. If the power ever goes out, this fan will be very handy on battery.

Although it's plastic, it's a great unit. I like it because it's larger than most portable fans. I also like it because you can plug it in the wall, add batteries and charge it with USB cable. I plan on buying some recharageable batteries so i can use them over and over. It's easy to pick up and go because it folds up. Also, you can set it at many different angles, which is wonderful. It's so portable and easy to grab and go if you're going to the beach, working in the yard, going on a picnic or camping. My grandson used it when he spent a week with us and ran it all the time in his room. This is a great unit and has a lot of options.

It works well on batteries and when it is plugged in. Very quiet when it is on low speed, not to bad on high. I bought extra batteries to take with me in case the batteries don't last for the whole trip.

I ordered this product for a camping trip where the "lows" were going to be mid-70s at best. I ran this off of 6D batteries (not included). I was camping for 4 nights and 3 days, running this fan continuously on high at night and intermittent during the day, for about 8-10/day....so around 40 hours on this set of batteries. Absolutely no issues. Perfect amount of noise for me, since I like a little white noise. No slow down of fan as the batteries "aged". My only complaint is that it can't point "down"... it only goes from flat to 90*, being able to move it a little past that point would have been nice as it was apt to slip if I tried to stack items for it to sit on at an angle. I've used this style fan in the past and it is far superior to the smaller rechargeable fans, which i'm lucky to get 6 hours out of on a single charge AND are much smaller. Batteries are an investment and heavy, but they work so very well. I'd absolutely purchase again, as this is my third fan of this kind, and all three are still in use!

We have used two OZCOOL battery powered fans for camping trips for years. THis one has the added plus of being able to be plugged in, so it works great for the camping sites we get that have power. Great in summer power outages. My wife though, she has hot flashes and put this one on her nightstand, plugged in with the fan blowing right on her head. Its quiet, and whether plugged in or on batteries, it really puts out some air. Has low or high, has a way to set the angle to angle down if needed. Folds up very compactly. Ill get a second one of these that have plugs as well as batteries. THis is a great buy/

This little fan has enough flow and noise to meet my wife's requirements for hotel stays. The power chord is long and the unit is sturdy. It fits nicely into a carry on sized suitcase. Would recommend for any traveler.

The fan I received functioned as far as turning on/off/high/low. Three stars because it did function, shipped fast, and arrived undamaged. However, as far as moving air at my festival to try and stay comfortable was akin to a person blowing their breath on me from about three feet away as hard as they can. I am at a loss as to all the positive reviews, perhaps I received a weak one? It seems like yesteryears inefficient engineering from the 1970s.

This is a great product for the money. The fan is quite powerful on high and has the option of a lower speed. This product is better than most camp fans and folds to pack-up when not needed. Nice, just buy it.

El aparato perfecto cuando deja la luz

Update 21Jun23 -- incredible machine, still going strong all seasons. Battery tip, since Amazon jacked their's so high in price, tried Dollarama's Panasonics, equal to the task and significantly cheaper.Update 14May22 D Size Adapter -- decided to return the adapters (noted below). Only got average four-to-six hours out of the AAs with adapters -- not worth the light weight and hassle changing so often. Get minimum 20 hours with Amazon gold D batteries, gone back to them.Update 25Apr22 -- Holy smokes, still going strong and definitely the best investment ever. Works fabulously with both AC and D Batteries. Recently bought a D Size Adapter that takes one AA battery and it also works great and is just a bit lighter-weight, although don't last as long as Amazon Basics gold D cells but alternative when you run out. (https://www.amazon.ca/gp/product/B076Q6SQM4/ref=ox_sc_saved_title_1?smid=A3P4UZIS42PRQV&psc=1). Now heading into warm weather and after working great through winter to help circulating heat it's now keeping me cool again. BTW, did buy a skinny paint brush to reach through grill to remove gunk from blades. After "brushing", tip and tap on the ground to dispose the gunk.Update 11Mar21 -- This is one of the best purchases I have ever made! It's still working VERY well with both AC and batteries in both cold (circulating heat from my camper van propane Mr. Heater) and hot weather to keep me cool. I can't imagine not having it.I have, however, found one thing that frustrates: it's solid one-piece plastic housing cannot be opened to clean the blades which are very, very dusty after more than two years of pretty much constant use. I've taken to using a 2-inch hair-rather-than-synthetic paint brush to try to clear the outer housing rings as much as possible. Might next try a skinny artist's brush to reach through the rings to the blades.Update 03Jul20 -- amazing device! Working really well still with both AC and batteries. Used all winter to help move the heat around from my propane Mr. Heater, and now the weather is getting hot and humid again so am using it to keep cool. Again, this size is so much better than a 5 or 6 inch fan in a camper. Really, it's absolutely worth the cost.Update 22Oct19 -- still working fantastically! Using it now to help heat flow around the space. One of my best purchases!Original Review 2018With both power and battery capacity, this is a really good fan. With batteries installed, when you plug in power supply it auto-switches to AC and doesn't run down the batteries. Am using in a camper van, and when I have power it's "FANtastic", and when on batteries it still has very good power. So glad I got this instead of a 5 or 6 inch battery-operated fan; the large 10 inch size gives much more air circulation. The batteries work for around 5-6 days on low running it for 4-6 hours per day. I've found turning off for a couple of hours seems to restore the batteries so they run strong again for at least a half hour before slowing down again. Another thing I noticed is that when I do use on AC power, that also seems to restore the batteries and they run again really well -- don't understand that, but it's a bonus for me.

This is one of the best portable fans I have had. It simply is amazing and meets its puprpose and is a wonderful traveling fan. The best part is I orderd and got it shipped from US with in week inspite me being in Cochin where normal couriers take ages.I wanted this to be taken with me on my tour to Europe where we are doing quite a bit of home stays in the country side where most homes don't have A/C or fan and in recent years European summers have become hot (temp in Spain was 39 degrees) and i have had bad experiences in the past as well, hence we decided to take a fan. Straight away knew the cheap Chinese fans (already having extremely poor reviews on amazon) would not be enough. After a long search finally found the O2-Cool series of fans.Not only it proved to be extremely useful it was also super light weight and did not add on to our overall weight limit in a bad way.Special mention of the company Ganapathy Global who sold it cheaper then many other sellers but also promptly responded to my email request for delivery within a week as I needed it for my travel and it came ahead of the time they promised.Please note: This product is for travel or to be used in close proximity and recommend using a light weight extension cable than buying the heavy and expensive rechargeable battery's (unless you are camping).

Absolutely excellent for blackouts you wouldn't possibly regret it

Es práctico para uso corto , culo una oficina oh cuarto pequeño no es muy ruidoso.
