Hi
I have a wireless microphone receiver that is powered by its own AC adapter. The adapter outputs 12V@200mA.
I'd like to use this in a situation where I won't have AC power available. The other components of my system have their own battery power.
My question is - could I rig up 8 x 1.5V AA (or any other size) batteries in series to power this receiver, or would that damage/kill the receiver. Is there a way to solve this without damaging it, and without having to purchase an expensive portable AC power pack?
Thanks for any advice
Mark
Hi again. You say the batteries will be drained rapidly. But if a standard 1.5V AA alkaline battery has a capacity of 2000 mAh, would the capacity of 8 in series at 12V be still 2000 mAh? I think that means I should expect the setup to last 10 hours, right?
I've never understood this stuff well, so thanks for the help.
Yes, you can use the way you said, but as Mr. Debasish said, the batteries will drain very quickly. Alternatively you can go for 12v DC rechargeable batteries with it's charger. So that you can also use a backup cell when it's charging and likewise.

PermalinkYes if the microphone is rated at 12V, you can certainly do that. but the batteries will be drained rapidly.
