willl converter operate without a battery in the circuit?

Sorry, I haven't tried it without battery connected. The fan does come on when I turn more than two lights on though, and when I put more load on it the fan speed seems to pick up commensurate with the load applied.

My basic answer is that the converter is used to charge up the battery for later use when not hooked up to a 110V circuit. Without the battery there would be no 12V lights or other usage low voltage use. The converter would operate but what good do you get from it?

Yes , as long as the output of the turbine is DC. Be careful not to exceed the current limits of the board. A diode to prevent over charging is a good idea. The battery won't duscharge through the converter.

Yes, you can run with only the supplied AC adaptor. Not necessary to have batteries.

I wouldn't think it would be a problem provided you have a converter to plug into when you charge the batteries.

There is no battery in this item. it works direct from the power supply 110V.

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, but when plugged in to 110v AC it does not use the battery. If the AC converter is plugged in to the unit it will not run on batteries even if it is unplugged from the wall.

It requires a constant 12v but only draws current to run the timer, which is minimal. I don't guess I understand the question. I don't know how it could be hooked up without a constant power supply. The timer is hooked in-line between te battery and the item needing to be turned on and off. I use it to control a solar heater. It comes on and turns off at a predetermined time.

As a general the answer would be no. Much of Europe runs on 208 or 220 current, which will fry your electronics without a convertor. That said, there are electronics out there which are designed and capable of running on multiple currents. Some electric shavers, for example.

No, you plug it in - Regular 110/120V No place for batteries - supposed to draw minimal power (equivalent to 30W light bulb??). Unit works great!

Does not require batteries. I used it in a low voltage application to turn on/off LED light strip. My power source was a 100-240V AC input to 12V DC output power adapter.

They can operate without battery but you need batteries if you want to switch on the built in amplifier.

No inverter necessary, however, you will want a charge controller, so that the battery is not over charged, and the panel does not discharge the battery when its not producing electricity.

No, it is not designed to run off of batteries, and there is no battery compartment, etc. Yes, it could run off of batteries provided you have some more advanced electrical knowledge or know someone with some-it runs off of dc electrical power, the same type of power your Duracells give you. But, it is a bit complicated. You would need to "construct" a battery pack for it in the sense that you need to come up with the rated power input from some battery/combination of batteries-it is 12v 3000mA DC input (at least that is what the supplied transformer outputs to the unit)-you would probably want to use a 12v battery of some kind (or for the size you want you might get 12v out of a combination of smaller voltage batteries in series) and then probably wire up to the dc input connector or take the back off and directly wire (i.e. solder) some battery leads to the inputs on the pcb. A laptop battery might work for this application. This would of course void your warranty.

My unit doesn't have a battery. It plugs into the house current and receives it's signal from the transformer attached to the house main door bell. (It works just fine.)

I would suspect that you could connect to a battery with a converter. Have not done that. There are solar fans that would not require electric power of any kind. We used this for one summer, took it to a desert location, planning to get a solar fan for it soon.

I am pretty sure the motor would burn out without a converter. We have US voltage converters built in to some of our sockets in the house as it is for the USA housing here.
