Treva 5 Inch Two Speed Battery & USB Powered Clip On Fan - Slim and Portable Cooling Travel Fan with USB - Gray

I use this portable fan while walking on the treadmill. The only downside to this fan is the location/placement of the screw that ensures the batteries remain with the unit: the screw is very small, and I don't find it sturdy enough. I accidentally dropped the fan, and the batteries went flying out of the unit.

I loved this fan..used it when I worked at Amazon as a packer. It is little bigger than I thought but it’s still great for portable fans an it lasted me for two years…until I forgot at the warehouse and someone stole it😭

At full power, this little fan gives a pretty good little breeze at close proximity, and the flexibility to blow in almost any direction once clipped on, making it perfect for a lap-top desk. I bought it to cool me off when the AC wasn't up to my Phoenix location, but also to sometimes cool off my gaming lap top, which can get a little warm to touch from time to time, not a desirable feature in the desert summers. ONLY problem was that the power cord could not get the fan far enough away from the PC to make it reasonable for the fan to blow ON the PC. I'm hoping it will work itself out IF I ordered the appropriate and longer cord to correct the situation (hope springs eternal) but all in all a good little product.

Works great in hunting blind to keep frost off windows. I use two of them for each side . Super quiet.

Bought used. According to Amazon item is very good no defects. Apparently not being able to move off/on/speed control switch IS NOT A NEEDED WORKING FEATURE!! I DO need the control switch to be WORKING. Disgusted that AMAZON allows broken used equipment to be resold from their warehouse as viable product.

Works as described

The airflow is strong for its size and it is surprisingly quiet. I primarily use it for when I build scale models and I use glue or solvents. I only use it with rechargeable batteries and I cant say exactly how long the batteries last but I have used it for 5-6h at low speed for about 4 days without any problem. As some have mentioned there is a screw that “holds” the battery “hatch” and its a pain to remove but you don’t actually need it because there are some clips that will keep it in place anyhow…. So just throw that screw away. It works perfectly to have it as a desktop fan, you can tilt and rotate it anyway you like. Overall, it’s a reliable, portable fan that does its job. Definitely recommend.

Compact but difficult battery compartment with tiny screw. Very short cord, too.

Es bueno velocidad con baterías

Batteries last all night into next day. I use 3 of these ariund the house ro move the heat from my pellet stove. I use rechargeable batteries. Woeks great.

I love this product. It has a nice feel to it. NOT a lightweight, cheap fan. It works very well. I need a fan to sleep and we are going car camping and this fan was so amazing!! I love that you can charge it with a usb or use batteries.
