how long the battery lasts?

I have never used it with the battery. I always use the USB plug plugged into my computer.

No battery in this unit. USB or plug in only. I really love this fan. Very quiet and efficient!

The plug shorted after 3 uses and the batteries didnt work at all. Disappointing. The first couple of uses were delightful.

There are no batteries. It either runs off the 110v plug or via a USB plug into your laptop. Mine will run all night without my laptop plugged in and only drain the battery from 100% to maybe 75% in 8 hours. Not too bad.

the battery last close to a month. depending on the frequency of usage it may last longer or lesser than that.

I've had it for about two years now, and the battery life on it is about two hours, give or take. It's definitely better than the one I replaced, though. I'm still a little disappointed that I have to practically keep my laptop plugged in just to be able to use it for longer periods. Hope this helps!

I haven't exactly timed how long the battery lasts, but depending on how much I use it, I generally need to charge it every day. Naturally I turn it off when I'm not using it, but I would say once a day with normal use.

Well, it depends how long you keep it on. In general, It lasts at least 9-12 hrs in a day when it's on, but if you use 'sleeping mode', it would be more than one day(at least one and a half day you don't need to charge it). Hope it helps.

Average Battery Life is about 4 hours. The product description, (That MOST people seem to ignore), is "UP TO 5 Hours." 5 Hour Battery Life IS NOT Guaranteed. On a FULL charge, battery lasts 4 to 4.5 hours.

Battery is supposed to last about 8 hours but can vary depending on volume, etc. I haven't really pushed it that far to see if it will last that long.

Mine is near 3 years old. Battery life is certainly shortened now (probably 10-12 minutes run time) but zero complaints about its performance. Gets used a few minutes every few days. I have been guilty of leaving it on charge a few days over the years. Certainly been a good value so far. Will likely built my own battery for it when the run time is unusable.

I am not sure of exactly how long but it seems to be about 2 hours or so. I have actually never timed it. This is an older laptop my kids use for games so that might be why the battery doesn't seem to last very long. Hope this helps! :)

I only use mine about half the day, but the battery last as long as I need it to. HINT: I charge it every morning before starting to use it.

Usually around 6-8 hours. I've never had the battery die on a full days use.

Around 1 month, and I use it daily. Howere, sometimes, the led light in front keep flashing, then the battery will last for a couple of days only.

The battery doesn't last as long as the specs say it will, but then again, that is the case with all computers. I use quite a bit of CPU throughout the day, so without charging I would say it lasts 4 to 5 hours. Given the amount of CPU I'm using, I'm very please with that. If you are just using Microsoft Word and maybe 2 tabs of whatever browser, I would imagine the battery lasts much longer than 4-5 hours.

Not long at all. Maybe 30 min from a completely dead battery. Lasts a good while too.

Hi,I have mine since two years ago, the battery had a duration between 2 and 3 hours, but since one year ago it last around 30-45 min.

I'm not sure about the battery life. But I haven't changed battery yet since I bought mine. Just be sure to turn it off after you use it.

I tend to keep mine on power save, it seems to last pretty well. I'm not sure and exact answer on a number but several hours.
