Does this work on battery? It came up when we searched "battery powered headphone amp" but it doesn't state it has battery...only DC12.

No, this headphone amp does not have battery capability. It runs on an adapter only. Does that affect my personal use of the unit? No not at all. I prefer dc current power over batteries.Less costly.

It will run off a 12v battery if you want to rig up a external rechargeable battery pack. I would use a 4 amp/hour gel-cell. That should be enough to run for at least eight hrs. before charging. It depends on how many headsets, the impedance, and how loud you push it. I run two amplifiers on one 4 AH battery for recording on location & never run low. One thing though, Behringer uses a 2.5mm center pin instead of 2.1mm for the 12vdc connector. If you want to make a power cable to run off battery, or use one power supply for several amplifiers, will need to get 2.1mm to 2.5mm adapters or 2.5mm connectors to make your own cables. Several ways to do it. Whatever meets your needs. It will run off a 12v battery if you want to rig up a external rechargeable battery pack. I would use a 4 amp/hour gel-cell.

Nope. Must be powered with AC adapter (included). Excellent buy, I have a pair of a Sony MDR-V6 headphones. Sound is crystal clear. But if you use this type of headphones be careful to not blow up your ears. It's what it's, an audio amplifier.

This unit is powered by a small wall-wart type AC adapter, it does not have the capability to use a battery.

I am very happy that it simply plugs in, no batteries to hassle with. We use it to amplify the headphones for treadmill use and it does that awesomely well!!! The noise canceling headphones drown out the treadmill noise, and this amplifier lets us ramp up the sound. We watch Netflix which has extremely uneven sound levels depending on the movie/program, so the amp is a great help.

The unit works only via a DC input - no normal facility for a battery. But if a battery is essential, a technician could certainly adapt a heavy duty battery and attach a chord which would power the unit. The unit is first rate, incidentally, and performs just as advertised.

No, it works ONLY with power adapter. I'm using it statically (only one location) and I'm very happy with the results. Just to be clear I'm not an audiophile, so if it affects the sounds in some light way I might not know about it.

it comes with a plastic battery pack that holds (8) AA batteries (batteries not included.. ) once the batteries are installed in the pack, the pack screws into the back of the amp.... Great little amp on A/C.. I have not used it on battery power though..

It does not contain a battery at all so never is charged. It must be plugged into the 12V socket to run. It will not drain your car battery if left plugged in while the vehicle is turned off. You simply plug one end into the 12V socket and the other end (1/8" jack) into your audio device. Then you tune and it works.

It doesn't seem I work while charging...but then if it did it would be more restrictive than just plugging your headphones into your player. It works with other headphones, which is what I use. The devise has a headphone jack like any other device.

I bought a 120W amp as well and at the same time. One had the 12V attachment and one didn't. Not sure which was which at this time. its a basic and simple connection on the back and something that works can be picked up from Radio Shack. I have not tried it to a 12V battery but I'm pretty certain it will work as the electronics in the amp are also created for this purpose. Hope this helps.

It runs on USB power or three AAA batteries. There are two cords: one that connects to the headphone outlet for audio, and one that connects to the usb outlet for power.

Did the description say it played a sound? I just saw it takes double A batteries. Had no idea it played a sound. Good to know. I'll look n see if I can find any literature.

Hello There. The battery powers the active preamp system. You only need the battery if you're plugging the Uke into an amplifier. Thanks! ~Todd, The Music Farm

12v battery that is needed is used to power your head unit. You head unit amplifies the power to each individual speaker output (usually 50w x 4). These speakers will not work without at least a 12v power source.

Mine only lasted barely an hour with ipod at 3/4 volume and the NuForce amp set on low. It may be defective so I don't know for sure. Product description says battery included. From what I gather it is not user assessable. I may return it after 3 trials of overnight full charge and doesn't last more than an hour.

It doesn't utilize a battery, it uses power from your camera. You do control whether your mic is on or off (if it's off, you'll record from the camera mic), and the direction the sound capturing takes.

I use mine plugged into an electrical outlet, but it comes with a AA battery in the transmitter that can be used for portable use. I cannot verify how well it works, but the battery in the headphones and transmitter should be fully charged for best results.

For the transmitter, there is a socket so you can plug in a 3 volt AC adaptor. For the headphones, no - I use AAA rechargeable batteries for it.

Mine uses AA batteries but quickly drains them of power 1-2 hours - if I'm lucky. I've tried using a ac/dc adapter with it when I hooked it up (via a patch cable) to my Boombox, it (CD player) shut down after an hour. I am disappointed - to put it mildly.

There is no battery. They do make a boombox attachment for this status 6 (Sirius SXABB1 Dual Mode Speaker Dock Boombox) and it has a headphone jack. I have one. It works great. But it is large (boombox size).

I think that the Beats by Dre headphones already have amplification built in to them (if they are the ones that require batteries), which makes this sort of a pointless purchase. There is, however, no reason that this will not work with those headphones.

I never ran it on a battery just a 3 to 6 Volt DC power device like for use with a cell phone. No you should not use a 12 Volt power supply. As a side note, I no longer use the product because range was very limited 10 ft. or so. I've since switch to a Bluetooth replacement with about 30 ft. range.
