Can I use this with power without charging?

Unfortunately, the quality of the unit was so poor that we returned withing a couple weeks of purchase. If we were more than 5 ft. from the unit with the wireless mic, the mic would cut out.

It has a rechargeable battery. Once the battery is charged, the speaker can be unplugged from the wall and you can move it anywhere. Depending on how loud you play it, the battery will last 4 or more hours. I actually bought the 600 first and like that one better. Lighter, just as loud, and battery lasts longer.

Yes they can all be used to power devices without a computer but the amount of power each port has is very low compared to what a device would get from its own ac adapter.

You can power it through the wall socket, but it only comes with a USB cord. I use my phone charger to plug it into the wall (my phone charger has a port for the cord).

You can leave it plugged in using a usb cable with a plug in adapter at the wall, similar to a lot of devices now that charge via usb cable. Just leave it plugged in and it will operate off electricity and keep the battery charged. Be aware that on mine the water in one speaker quit "dancing". Not sure what this was related to but probably not a power issue but defective.

Yes you can power this through a wall socket. You need a USB adaptor (same as IPhone). Output is on back.

No, it can only be used while unplugged, but it holds a charge for a good hour.

Definitely no! Without power it's totally dead - like a stone! You must connect it to power and then you can expect it to work - if there is no anything other wrong. If you don't want to use power, you can check another model - http://www.amazon.com/Anker%C2%AE-4-Port-Portable-Aluminum-2-Foot/dp/B00IJ331WY/ref=sr_1_2?ie=UTF8&qid=1416424283&sr=8-2&keywords=anker+usb+3.0+hub. It has only 4 ports and cannot charge devices, but it's more compact and doesn't power connection at all.

Yes and no. It needs to be plugged in to charge the device but after its done charging. You can used it without it being in the plug in.

You should be able to. It is audio/video in coaxial out. Yes it does use a power source

This unit runs on USB power. There is no need to plug this into an electric socket.

No. The unit is powered from a permanently sealed battery with 10 year life and cannot use external power, so there would be no point in doing so.

No you can't unless you have a small usb connection attached to an electrical plugin like some phones have. Otherwise you will have to use a computer to charge it.

it will operate without power, as long as the device has a power adapter of its own. so mostly, it does require power. my machine still sleeps, but it will disconnect the device abruptly, meaning possible data loss.

You can but your power consumption has to be very low, add a battery and then you can run some stuff, charges kind of slow though.

You can use the device without the solar panels connected. The panels are just used to charge the device.

Yes you can power it while it's recording, no you can't charge it while it's recording. The manual clearly states this.

Don't see why not. I use mine with a power booster that requires power, but it might work without the booster.
