Can the speakers run on battery?

I don't think so but I actually sent the speakers right back to Amazon because the rattle at low volumes. They are the worst speakers I have ever purchases... the rattle and crackle like there is no tomorrow...

No they must have an outlet to plug into. Sound is great for a computer or smaller area, not meant for a bigger space.

Maybe if you're ingenious but the manufacturer did not include any way of doing that. You need to plug it in... Really enjoyable speakers anyway.

I don't know. You need a usb port and an audio jack. If you have those it should work. Or, if you charge it on another computer that has a usb port it will run for quite awhile on it's battery with just the audio jack plugged in. Hope this helps. It's a good little speaker.

yes, you can. in that way you don't even have to worry about the battery running down. i had mine plugged on in my van and it played continuously.

Yes the speaker works while plugged in or by battery alone. I have purchased 3 of these speakers (bought parents two). I love them & stays charged too

Yes but you have to have an external amp or receiver to power the speakers.

This speaker requires batteries if you want to have it portable, but if you have no batteries it can turn on and play just as well if you plug it into the wall. The batteries are just for it to be completely portable, but the plug is also portable so just bring that around and look for an outlet to plug your system and there will be no need for batteries.

The speakers are powered via the USB connector, you don´t need an extra power source.

Mine does not have a battery but plugs into the wall. The sound is great with great bass. I have been very happy with the speakers.

For power from the speakers, you would want 2 or preferably 3 AA batteries. 2 AAA batteries sounds like it's for headphones only.

Hello,I see you had a question, to answer your concern: these speakers donot require batteries, nor do you have to plug into a electrical outlet. A USB plugin and sound input is all that's required.

Nope. The battery is for the noise canceling feature. But can't run them without the noise canceling feature on.

there is no battery this is a acoustic set not electric and even if it was a electric it still would not have a battery. So I would have to say no......

Yes, you can. However, it will drain the power from the speaker at a much faster rate.

They are wireless if you want to use batteries, 6 "c" size for each speaker. I have them plugged in to the AC adapters that came with them.

Speakers must be plugged in to a normal household outlet (110v), or there is a compartment for 8 c-type batteries in each speaker. There is no provision for recharging. I have never used the battery feature, therefore I have no knowledge of performance or battery life.

These speakers are not self powered nor a complete sound system, so this question is not really appropriate for asking on a set of speakers that requires other components. (The only input ports in the back are speaker wire inputs.) If you are designing your own system, where you plan to connect external devices and even run things on a battery without an AC connection, yes, these things are possible. I am actually doing these things with my system. These are 4 Ohm, speakers, so imagine that if you connect these speakers to a car stereo, the requirement list that you have, is really meant for the particular car stereo unit. So, with this example, the car stereo would have a USB port, 3.5mm audio jack for MP3 player input, and it may even run off of a battery. If you are just looking for a complete sound system that is ready to go, this is not it.

From the phrasing of your question, I'm left a bit confused. But I think you are asking if these speakers can operate on a charged battery. If so, then no. No, the Microlab h21 speakers are not an alternative to portable Bluetooth speakers. They are bookshelf speakers, meant to be placed in the home. They must be plugged into an outlet to function.
