Can the speakers be powered from the AC power supply without having to be charged?

This particular speaker powers off of AC power... It doesn't run on DC current. However, they are great speakers, I don't think you will be disappointed. Hope this answers your question.

These speakers must be powered by the ac cord, they are not battery powered, so there is no charging involved.

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.

Yes!These speakers are powered by the subwoofer or the amp (depending on your system) not directly by the wall power source.

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

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

Scott, you will need access to a wall outlet for these speakers. There is no way to power them without the wall plug.

No. Not at all. They are powered by AC power. You will have to plug them into the wall plug as well.

Great question! The speakers get their electrical power via your device's USB port! No wall socket adapter needed.

No, it needs a power source. Ac/ DC connection. No headphone connection either

No, these are traditional component speakers and are not self-powered. Hope this helps. Barry

These speakers are not active and do not require electrical power. They have only one speaker wire input.

Unfortunately not. Those are powered from the computer itself, these have an external ac port and a speaker plug (3.5mm or whatever the standard is now)

Yes, but you need to buy batteries for the unit. It does come with a power supply that will charge the batteries. You can also run these off the AC power supply while the batteries are charging.

Why would you want to? The speakers are supposed to be one of it's best characteristics. It could be done but probably won't supply the power needed and you'll damage the system.

Yes, there is an AC power cord that is attached to the speakers that plugs into a standard wall outlet. This cord is attached to the speakers and will be located behind the chair the user is sitting in.

The speakers are powered. All you need is an audio source. Computer, TV, MP3 player, etc.
