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.

Not without modifying connections and needs amp to power speakers as a computer will not...

Sorry, but no. The speakers get their power from a powered USB port on the connected device. There's two cables that come from the speakers - one is a USB connector that plugs into the PC or Mac for power and the other is an audio connector that plugs into the headphone jack of the PC or Mac. I bought these speakers to connect to a used Mac that had no audio to the speakers (but still had headphone audio) and they work great. Unlike the iPad Mini, the Mac has a powered USB port.I suppose you could try connecting the USB connector of the speakers to a USB charging plug, but I don't know if that will work and that seems inconvenient for a mobile device like the iPad Mini.

the speakers charge through USB so you don't remove the batteries to charge the device. Hope this helps! =D

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.

they sure can. the have the mini plug but you do have to power them to a ac outlet. they are not used as a usb type of connector. if you use the laptop as a desktop you would just unplug connector from laptop and remove the laptop to use somewhere else, leaving the speakers.

The speakers aren't powered through any computer connection and require to be plugged into an outlet.

I suppose you could in theory, but since these speakers have no internal power supply you'd need some form of amplification between the speakers and the pc. Not really the use they're intended for.

No, these speakers get power from a USB port and source input from a hard wired auxiliary cable. There are no other inputs or outputs

You do not need an amp to run the speakers, but it it's highly recommended to get the most sound from these speakers. The blue LED lights will need a 12 volt power supply.

No, these are NOT powered speakers. The only connection is the speaker wire.

The speakers are powered by 110v house current, or it also has provision for batteries (that I have never used). They work well on house current.

that is correct - USB cable & AC power source (adapter is supplied) for the speakers as they have a pretty powerful amp in them!

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

I'm fairly certain that you can achieve this. I have Logitech Z5 speakers which are also USB powered, and I have used a USB charger to power them while the device (like an ipod) plays thru the audio cable.

No, they all must be powered. I tried that at first and had to return the non-powered speaker. I bought a second powered speaker and they worked perfectly together. It's a little more expensive for the powered version but it was worth it for me.
