Do the speakers have rechargeable batteries? If not, what are the powering options for the speakers?

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.

Can connect to 110 electricity or use regular batteries. (Not rechargeable). Either works fine.

This speaker has a battery life of about 8 hours. If the battery is low, it can also play while charging. So, it is both portable and rechargeable. This speaker is truly unbelievable for the price.

We use Energizer Lithium batteries. They are not rechargeable, but they have lasted through 2 hour services and only got down to maybe 75%. We put in fresh batteries for "important" presentations, and use old ones for let formal occasions.

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.

No man, it doesn't have an internal battery sadly. By portable they just mean self contained. Its quite heavy though. Slightly awkward to lug around. Great speakers though. Definitely worth the price tag IMO. You will need a 110v power source to operate them at all times though. You can run it on a car battery with the 12v adapter. Gotta leave the vehicle running though or it'll drain it fast.

The rechargeable battery is to be used to charge the headphones as when your out and want to use your speakers the battery can die.

Yes, they do need to be charged to play. They come with a rechargeable battery (seems to be) permanently mounted inside the unit. The speaker comes packaged with a short USB cord (detachable) that you can plug into your computer, etc. to charge it up.

Yes they do- The usb cord coming from the speakers acts as a power source- unless you use a bb or iphone charger for the wall

Yes, these are rechargeable. Charge via USB to outlet or PC/Mac. I've had them for a year and my daughter loves them.

The speakers plug in to any outlet. The box also plugs in to an outlet. There is no battery.

They come with rechargable batteries. They seem to be lasting pretty long. My lights stay on all night and the first set of lights I purchased are over 6 months old. So far so good. I have heard from others that the Moonray batteries are some of the best.

I actually have not used the speaker with just the batteries on. I have been using it plugged in all the time.I am now curious to see if that happens if I tried it with just the batteries. It could a power saving mode.

Unfortunately there seems to be an issue with the item description. These headphones have a rechargeable battery that is built-in. It is recharged via the miniUSB connection on the headphones and lasts 18+ hours per charge.

Yes, the head phones are rechargeable, they come with a USB cable to charge them with. I usually charge mine for ~2 hours and can easily get 8 hours of listening time out of them. When I don't use them much I can get by with charging them every 3 days.

No they are not rechargeable. However, it takes standard AA batteries that can be substituted with rechargeable AA batteries.

the speakers are powered by plugging the USB cable into your computer. I turn my computer off at night, so they turn off as well. If you leave your computer on 24/7, You would have to unplug them when not in use.

Yes, the speakers need to be charged up from your computer, then they can be used for about 18 hours before needing a recharge.
