I'm looking at charging a lav mic transmitter w/ the requirements: "13-15v dc nominal 500 ma" will this 12.6v do, or do I need something stronger?

Depends on what the lowest voltage your device can function at. The battery pack voltage is lower than what you specify. It actually puts out about 12.2v when fully charged but will drop to around 10.5 to 11v as it discharges. It is not a true 12v battery pack by design.

DC 6V 800mA is what it says on the side of the device that it needs,.. Ive personal never used it on my current one. My friend who had used this when it came our ten years ago had the cord and used it all the time. The machine would get hot if you used it for to long. So keep this in mine. (We are talking like a hours at a time.) I just use this for 15 or 30 minute uses with a battery though.

I don't know the power as I haven't a means to test it, but I'd assume that 500mA is what they provide. I do know that they provide power and I use thme to charge usb speakers, a small helicopter, usb headset and many other devices as well as a Nook HD+ and IPad all at the same time. I also use it as a hub when I'm on my desktop computer (usually on the laptop).

This one should do the trick. It's 150w and 19.5v. It's great for my power hungry alienware. Good luck!

Try this one bro. Has good reviews and supports up to 500w, automatic and quite portable. http://www.amazon.com/Automatic-Transformer-Adapter-500W-110v/dp/B001TPZ294/ or this also looks good but up to 200w and lighter http://www.amazon.com/Portable-universal-converter-charging-MRJ201GU/dp/B00F877VES/

any 12 volt dc current is usable, weather it is from a battery or a transformer pack it does not know the difference - be careful to get the polarity correct...

I bought mine for running a Humminbird depth finder in the house. It will power anything needing 12 DC as long as it is less than 3 amps.

Amperage doesnt matter. As long as Voltage is same, the camera device will pull the amperage it needs. For a camera, a 12V supply with 2amp output should work fine.

Its 110v. Check with website they might have an adapter. Not rechargeable. Only mics use batteries. Don't loose the remote like we did cause you cannot turn on without it and it cost over 50 dollars to order remote!

Not certain but probably. I'm guessing the transformer that it requires is 40-50wattt, I'm sure 12v/5A is plenty good.

It puts out 12vdc at up to 2 amps. If you only need 500ma, this has more capacity.

Hmm... I am not any professional by any means but when dealing with condensor mic's you need to provide a lot more power than regular dynamic mics uses. I think like 48 volts. Maybe that the issue?

12 volt DC 500 ma or higher ( I use a multi output power supply that powers up to 16 cameras mostly)

Yes, your device will only pull Amperage (mA) it needs. In your case 500mA. Adapter is capable of providing up to 2000mA.

I've always charged this device using a USB 2.0 or 3.0 port on my desktop. These ports are 5 VDC, & are capable of supplying 500 mA & 900 mA respectively. However, if you're using a USB port powered from your car aux port or from a wall socket, it may supply as much as 2.1 amps, which doesn't seem to present any problems for most of my equipment that's charged via USB (phones, MP3s, etc.), so I'm guessing this amplifier would be okay & I wouldn't hesitate to use it if necessary. Hope this is what you were looking for.

Yes, I power mine with an external lithium ion battery pack which lists it's output at 9-12v, the label on the unit says 10.5VDC. I use this with my camcorder to tape youth soccer games, and keep the external battery pack in my backpack which I hang on my tripod, so I don't have the additional weight of a battery hanging on the back of the screen, which is mounted on an articulating arm. Any 9-16VDC source should work, as long as it can supply enough current too.

Should work fine - I would suggest using minimum 18ga wire, especially if it's a long run. The combined current draw would be approx 4.5A which a lighter plug should easily handle.
