Is there a way to make it last the 8 hours it claims it can do? Barely made it 4 hrs., I want it to run thru the night!!

Mine runs for 8 hours. I fill the water all the way up to the line. How far are you filling it up?

You're right! Mine doesn't run the 8 hours either. I've actually stopped using this one and went back to the one by Green Air. It DOES last 8 hours and the oils are diffused better (not sure why). I might use it lot add a nice scent to a room, but still, why would I use this one when the other one works better and I can benefit from the oils better?!

You have to clean it every time you use it. I use vinegar and a q tip. Every few days I leave vinegar in overnight. Mine works great, and always lasts about eight to ten hours.

I turn off all the lights, make sure it is filled to the line, and that it sits evenly on the surface. Mine has gone through the night. Hope this helps!

I've noticed the length of time it runs varies a lot if the house is to dry and room size. It will run all night in the kids room but but not always the 8 in the kitchen. Kept it clean helps a lot as well.

I don't have a problem with it running for 8 hours. I think it might have to do with the light warming the water and it evaporating.

I'm wondering if it has to do with the type of water that is used. If it is distilled, tap water, from a water softener, etc. I seemed to notice a difference in the length of time when I moved.

I read on another Now Diffuser review that you have to use tepid water and not overly cold or hot or it will shut the unit off.

I have 4 of these and do not have any issues with it lasting 6-8 hours. I usually do not run the lights on, but I know they do in the kids room and it runs for the normal time.

Theres an app that does that. Just do it 3 hours before bed. Let it die. Plug it in turn it on charge over night then use regularly repeat 6 or 7 times a little bit of a hassle i know. But its worth it.

I've been testing mine out recently - I run for about 2hours, 2hours 15 mins. It usually lasts 2 such days - so 4- 4 1/2 hours- which is quite disappointing. I have a feeling indoor battery life maybe slightly better. I was looking for the "rated" battery like myself. Would be nicer if it went a week without charge.

I've had mine last me a couple of days, running it after work until bed time. Right now I've been running it every night with some Sweet Dream oil and it still has plenty to go.

I have had mine for a couple of years. It does stay on for more than 4 hours. Unless they improved the battery draumatically you will not get 6 - 8 hours.

I start mine about 10 PM and it will run all night and shuts off around 7 AM. Hope you enjoy yours as much as I do mine.

Hey bro...i just got mine yesterday and I've used it for so far 3 to 4 hours...and it works well...I'll make sure I put it up on exactly how many hours the batteries will last...

It does run for 8 hrs, I ran ours every night but ithas stopped working after about 30 days.

I don't know that I would leave anything running 24/7 but don't see why you couldn't. What I did was get a timer so it would go on and off regularly without any effort on my part. That way it can run at the most important times for four hours three times a day.

I haven't had this problem but perhaps you didn't run it for 15-20 min. before using it. Check out this link.https://www.youtube.com/watch?v=xNzAZAUppgE&index;=37&list;=FLiemuFl8hOFg0b-PY3smWrQhttps://www.youtube.com/watch?v=xNzAZAUppgE&index;=37&list;=FLiemuFl8hOFg0b-PY3smWrQ

On its own it will run for 8 hours. It is simple to interrupt this though, just open the lid. I do it all the time.

I'd say ours last about 3 weeks, considering it stays on for a half hour at a time and we usually put it on 2-3 times a night it's not too bad but we will probably invest in rechargeable batteries for it. It is a lifesaver though!!!

What everyone else has told you here is true. The only thing I would add is that you may want to play w/ the time in order to fine tune it. I have an 80gal. tank, & have it come on for 1.5hrs in the morning about 6am & again at 6pm. This satisfies all our needs for the day. If you have a cheaper rate at night, time it to come on for the amount of time you determine so that it goes off at the time the rate does too. If the heater is satisfied before the time is up, it won't be on anyway...Remember to reset the clock after a noticeable power outage however!!!

The one I bought was also lasting in about 2 hours. Just buy more expensive

Sorry i set my timer to run during the night and i have never checked to see it it is functing correctley. Instructions were shipped with the device and it was simple to set ( I think.) I will try to check it this up an comming week end. Then I will get back to you later on this site if you don't already have the solution.

I had the same question!!!! No matter how long it's in, when you take it out the heat only last for a few minutes, so you're up and down all day/night...so maybe some one else can answer that question for both of us...( I hope)

When mine starts to go a little dim I plug it in at the end of the day an its ready to go the next morning.sorry but I don't know how many hours it takes exactly. I don't think the battery will last for a straight 8 hr but it should last a straight 4 hr. I like mine very much and would buy another one. And its tougher than some people say, I left mine under the car when i let it down, an all that broke was the hook on the top, a little NP1 and its fine.
