what's the noise like for this, does it buzz, does it beep when the battery is low, fans always on, fans loud?

I have only had mine installed for a week. It's installed in the front of my 2011 Chevy 3500 HD. I haven't ran the battery down with it because I leave the engine running if it's on. I highly recommend doing that if your gonna use it because as I understand it, it will drain one fairly quickly. I can't tell if the fans are on all the time. Honestly I haven't checked. That said it's quiet. Real quiet. I had a small inverter that plugged into the cig lighter that was much louder and annoying than this one by far. I bought it to charge cordless batteries for my drill. They require pure sine wave stuff because the others will fry your batteries. I also use it now for several other things like laptop, tablet and even a knife sharpener. So far very happy with it.

This is a tiny unit and the fan has to work hard. It is always noticeable. After over a thousand hours of use, sometimes when I boot up, it's ABNORMALLY loud. The bearings are wearing out. Usually, rebooting once or twice restores the "normal" fan noise. This is why my audio system is separate; the built-in speaker can't compete.

There is very little noise with my unit when the fan isn't running. And the only times so far that the fans have kicked in were when I had it hooked to my TV as an external display. Don't get me wrong, the fans are far from silent when they do kick in, but with fairly normal use, they usually don't.

It makes a humming noise as all fans do. Now I'm sensitive to noise when I sleep but this one is not so loud so I have no problem sleeping with it on.

Mine makes a little bit of of noise, but not too much. I believe it has an internal cooling fan, but I'm not 100% sure on that. Sorry, this probably not that much help.

It is very quiet. It does have a fan and occasionally it is loud if the computer is "working hard". I would say the fan is on very low 90% of the time and you can barely hear it.

There are 6 white noise settings and 6 fan settings. For each, it's just a variation of pitch from low to high. The white noise is very constant static. The fan setting is more of a hum with just the slightest sound of oscillation. I find the fam setting more appealing- The lower pitch is sort of like sleeping on an airplane

I don't hear any noise or hum from any fan. The only thing that i didn't like is that when unplugged or the power goes out for any length of time there is a loud alarm until the power comes back on. Kinda annoying! but that is the only problem i have with it. Otherwise it is a great backup battery for my TV and cable box.

If you use the fan, it has a high pitch/whiney noise when using the a/c adapter. on battery the fan is pretty mellow, so much its fairly useless. So buy the a/c adapter if you want the air circulated around.

It depends on the load but you will begin to hear the fan cut on when it starts to pull a certain load, and then it will beep if the load is to much on the device. There is a breaker on it so it will shutoff if the load is too much. But when kept at relatively normal levels it can run all day.

I call it quiet, even under load. I still hear fans, but they don't overwhelm my tiny speaker system. If you want zero noise, then this won't work.

Probably not what you are asking about however, I had a fan problem with mine but not right away. After 5 days of ownership, I carried around my N120 and the following day the fan was making a rattling noise. The fan blade was obviously hitting something (similar to a stick hitting bicycle spokes). It appears there was something lose that decided to interfere with the fan blades. It would go away once it is powered down, it would also change volume if you move the computer around. Otherwise, the fan is quiet and normal, no vibration.

No. In fact the fan noise can be quite loud. The biggest negative on an otherwise impressive device.

It's not very loud. I sleep with the ceiling fan on and this thing too, and sometimes I can't tell if it's on. The fan is basically what you would find in a computer tower so the noise is minimal. A slight humm if anything

It isn't loud at all. There is a slight hum, but not one you really notice. If you ever heard a small fan, the ones you push the button and they blow in your face, it's kind of like that.

The fan isnt very loud at all, kind of a very low hum......used it camping about 2 weeks ago. We like it alot.

Not bad, constant hum. There are 3 fans, they do a good job of moving air around. You can definitely hear it but Its never been anything that annoyed me or I even noticed.
