SmartDevil Portable Small Humidifier, 2000mAh Mini Personal Humidifier, 600ml USB Desk Humidifier for Plant, Bedroom, Office, Travel, Baby, Auto Shut-Off, 2 Mist Modes, Super Quiet (White)

I can confirm that the battery lasts 8 hours. Is quite small & has a tiny tank, but this makes it quite light & portable.If you are never gonna move it around, then get a proper plugin diffuser.

no trouble sleeping because there is no sound at all

Super silent, portability is great. Battery lasts ages especially on intermittent mode. Very happy.

Weak mist. Not working after few weeks

I originally bought this for a prop for a video on weaving linen but it didn't create enough moisture for that.Instead, I use it for my houseplants and it looks beautiful among the foliage. The humidity increases with it on and the plants seem happier (insofar as plants can seem happy) for it.It comes with a replacement filter and charging cable. The wood appearance is plastic, which is probably best considering it's designed to be moist. But it looks like wood from a distance.Two things I don't like about it.1) the battery only lasts about 4 hours on full and 5 hours on intermittent. The description promised 8 hours :(2) the charging cable is USB-C rather than the micro USB that everything else in the house takes. So now I have to have yet another cable to keep track of. But that's okay because it's charging so often...It turns off automatically when the battery is low. I have been running it every day for a week now and I'm only halfway through the water supply so I don't know yet if it does turn off when dry.

I love that it recharges, and I can move it around to where my plants need it. I'll buy a couple more as I go, so I can have one or two charging, while the others are going, So much less inconvenient than my big one - it's not top fill and this one is. I like that I can just pull the top off, OR top up with the lid on. Lasts pretty long on intermittent setting, which is great. The ones that blow continually usually end up with water pooling on a surface somewhere, and this prevents that. It recharges pretty quickly if you have a usb charger to the mains that has a mid speed. My advice is not to use a 'fast charge' rated usb charger - it can affect your battery life.So far so good!

I have been using this for 2 months now. It has two operating functions; continuous and intermittent mist stream. I mostly use the latter and it can last about 9 hours on a full charge and use only half of water. My plants love it. Great humidifier!

The mist is hard to see on light backgrounds but it’s there! The instructions are in Chinese so I put it in translate. People were complaining about the noise, but it says to turn off the machine and start in a minute. The noise is from the cotton not being fully submerged in the water. It’s a good product, light and easy to use

If you are wanting better results, I would suggest just going with a larger humidifier. I have this for my small camp room at work, and it makes a small improvement to how stuffy I feel. It's definitely really cute, asthetically. But for actual health benefits its not the best. It has to stay plugged in throughout the night, battery life is probably around 4 hrs without being plugged in. It's okay!
