I've had the handy cooler for just over a year now and so far I really like it. It's been lying under my bed for the whole winter, but now the heat is back and I've brought it back in action.
What I liked:
- The design. Looks good. Feels good. I like the swivel vent head too.
- Portability. I bring it around to classes, work and around home.
- Performance. Cools like a charm.
- Size and weight.
What I would like to see improved:
- Rechargeable lithium battery option. The unit is not capable of recharging batteries. However, I recommend getting 4 rechargeable batteries, and charge them with battery docks. It'll cost you $40+ but will save you on the long run.
- Longer cooling duration.
- a longer USB cord!
It's a nice little fan with a twist, but be sure to stock up on batteries.
So let's just get straight to the point - The product itself is very light, even with a soaked sponge and batteries included it was easy to hold and re-position the fan by tilting the head. Another feature why I chose this model over the original is its ability to power itself via USB, which I happily did on my laptops USB port through out my trip. Other features found on both models are the obvious hand straps, which I thought did an excellent job. It was comfortable and best of all it was also adjustable. So we had no trouble re-adjusting it when needed.
Function wise, I think it went beyond the call of duty. I know that some might think that's a bit exaggerated but my trip to a tropical country like Indonesia really tested the product. With temperatures ranging from the upper 90's and with humidity that felt like cutting through butter, the fan did its job. As for the battery life, I never really ran out, let's face it ... in reality I didn't need it on 24/7. While walking throughout the streets on some days I would have it on and then off again if I stepped inside an air conditioned complex or a restaurant. So for those who claim that this doesn't have a long battery life need to check again on how they used the product when writing a review. On top of that my usages were based on regular alkaline batteries and it performed fantastic.
Onto other aspects, I have ready some reviews where people have said that the fan makes a loud or rattling sound when on the highest setting. Just turning it off and on fixed the problem, if that doesn't help, just off it, open the case, re close it and turn it back on, nothing a little tinkering cannot fix. As far as noise is concerned it's not going to break your ear. Also in regards to sounds, I could hear people who talk louder than this fan in restaurants and in places where I was seated outside. The only thing I would have liked more in this fan would have been a larger cooling area, but given the size, perhaps that wasn't feasible in the design aspect. Perhaps in the next model! Who knows?
- Small and light
- Great battery life
- USB powered
- Cools like a charm (this is a fan so lets be realistic, it not going to bring the temperature down from 89 to 60 degrees, but it'll feel like the 70's and once again this will also depend on the weather around you on how cool you will feel)
- Use of AA batteries, very common and easy to find
- Sponge is small and dries faster depending on the weather! So be prepared, its not the machines fault that you didn't prepare for this. Yes the sponge should be damp in order to get the maximum output. So do your self a favor, carry an extra bottle of water or even go to the rest room and just soak it up again. I had no problem doing both!
- Cooling distance is short. Once again this is a hand held/ table top device and you cant blame the device for this. Its wasn't built to beam cool air across the room. In my experience a good 2-3 feet did the job.
Anyway thanks everyone for reading this review, and let me know if it helped or if you have any questions!
There are two things that you should understand about this. First, the effectiveness of the cooling depends on the relative humidity; it cools well in a dry climate, but is no better than a simple fan in a moist climate. Weather forecasters often give temperature and relative humidity; but instead of relative humidity, a more useful value is the dew point, which is always less than or equal to the temperature. (The dew point for US cities is shown on the web site of the National Weather Service.) If T is the temperature and D is the difference between the temperature and the dew point, the air coming out of this device is roughly T-fD, where f is in the range 0.35 to 0.50.
For instance, on a hot afternoon (90 degrees) at my house, the air coming out of the fan is about 77 degrees; this is 13 degrees cooler than the ambient air and feels very pleasant. The dew point at my house in the summer is usually about 55 (all day), so the cooler is effective on hot afternoons. In a humid place like Miami, on the other hand, the summer dew point is about 75, so the cooler would have little effect.
The second point is that cooling occurs only when the filter is wet. (The filter is just a sponge cut to the right size.) How fast it dries depends on your climate and the fan speed. I find that after about 35 minutes, the portion of the filter right behind the fan has dried out; at that point, the amount of cooling diminishes from 13 to 5 degrees. The filter isn't yet completely dry, but it has become much less effective.
To summarize: First, this device requires a dry climate to provide much cooling. Second, you have to add more water to the filter fairly often to keep it moist.
The instructions say that you should apply 30 ml water to the filter (and a container is provided to assist you). When I use the device in my house, I find it easier to use a kitchen scale. The dry filter weighs 7 g, so I just add water until the total weight is about 37 g. If you put in too much water, it can puddle at the bottom or drip out if you turn the device.
