Can it be powered by the USB port on the side without the need of the wall wart adapter?

No, the unit requires the wall wart in order to supply the 5 volts at 1 amp of power needed.
449947
No. I'm pretty sure it says somewhere in the product description that the device can't be powered by a USB port.

Yes, I just tested it. FYI, use the RCA jack outputs for best sound. The 3.5mm jack is for low power headphones only.

Mine came with a "wall-wart" type USB power supply right in the box. Any 5v DC power supply that puts out 1.8 to 2.0 amps should work fine

No and yes (it charges/runs devices off of the bus at that point). Keep in mind with no supplemental power you will be limited by whatever the USB bus can provide on it's own (5v, 500mA for 2.0 and 900mA for 3.0 bus)

You can use any usb port on a computer, wall wart, or usb charger. You can also find them on Amazon for really cheap. I have them plugged in all over for charging mobile devices

It is battery powered. You can probably get a wall wart adapter at Radio Shack.

Unfortunately it can't be run without the plug in wall adapter. I was hoping it could run off of USB power cord that is supplied with it but it turns out the USB attachment is only meant to power the LED's.

I don't think so but you can buy a USB wall socket adapter for 5$ from any walgreens, rite aid, Walmart etc

The power supply for this item is a typical "wall wart," roughly cubical in shape with an AC plug attached, and measuring about 2 3/8 by 2 by 1 3/4. Output is 19V. I'm not looking at it right now, but I can get current capacity if you need it.

USB ports can only supply limited DC power. Sometimes a two or three port passive (no power supply) USB hub can be useful, but don't expect a seven port hub to operate without a separate power supply. If you're inventive, you can construct a battery power supply with parts from Radio Shack so that you can occasionally operate away from utility power.

Can be powered through a wall socket, that's how I have it set up. I haven't tried the laptop features yet.

To power it through the wall you have to buy the USB plug, that's how I power it, I haven't even hooked it up to my laptop yet.

As a general rule of thumb, any USB device that can connect to a USB power supply will charge. There isn't such a concept as "wall charger only" anymore, since electricity passes through USB devices. So, I would say yes.

More correctly, no, the unit requires 12 volts DC. However, you can buy a wall wart on Amazon or eBay that will do the job. You'll want one with an OUTPUT stated to be 12 vdc (volts DC), and 2 amps or greater. You'll have to connect the power supply wires to the monitor wires yourself.

Technically, the answer is yes; it gains its power externally--it has no internal power source. However, in common parlance the answer the answer is no, since it gains its power through the usb and does not have a separate power cord or connection.

Yes. The USB port is also the charging port. I charge mine from my computer when I'm on it and from the wall charger when I'm not on it.

Yes, though these adapters are low quality and don't last long. I've had better results buying cheap usb to 2.5mm cords that plug into a 5v ac to USB wall wart. Then if the plug end breaks I just replace the usb cord and can keep using the same ac adapter over and over.

i dont think so, just because its usb powered. you could maybe use a usb to ac outlet adapter to power it (same as the one you would use to charge some phones using a wall outlet), as long as the volts and amps match up well enough.
