Are batteries an option for power?

Yes, you can put 3 x AA cells in it, then there is a switch on the front to select whether it runs off those or the internal rechargeable battery pack.

No, you supply your own 4 AA batteries. You could still use your own rechargeable batteries.

While it does not support a battery power option, you could purchase a APC battery backup for the times when energy is down.

If you mean batteries, no. All I see is the input for a DC 12V power adapter, and a compartment simillar to the ones for batteries, but this is for carrying the adapter arround.

Can connect to 110 electricity or use regular batteries. (Not rechargeable). Either works fine.

I never installed batteries but as I recall it needs them or the AC power to operate.

I own a couple of these and the only way to power them on location is via extension cord or a generator. Harbor Freight sales some inexpensive generators. They are not ac/dc, if they are there is nothing on their website stating what battery to use. Hope that helps.

Yes. The batteries that were supplied with my unit were cheopos I have seen at frys. You can probably use regular batteries or get a good set of rechargables.

If in a remote area with no power available, then a solar panel and 12v battery can be used for power. Available here from Amazon.

No, it is only battery powered. Not sure why anyone would really need that capability, provided you can plan ahead an hour or so to charge a depleted battery, if that is ever the case.

You should provide power to each unit. If that is impractical, there are battery operated units that have ten-year batteries.

You can plug it in and you have the option to use batteries. I had mine for almost a year and never put a battery in it.

I know there is a battery backup, but I have mine plugged into an outlet. I don't know how long the battery is supposed to last, but I wouldn't recommend it as your primary source of power.

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.

Require a power supply: No; Batteries: My book says "to provide back up power". Others have mentioned that the batteries don't last to long

No. You will need an electronic inverter that is designed to connect to the electric grid. You also need an agreement with your electric company for them to buy your solar electricity. If that is all you need, then you don't need batteries.

As far as I know you can power it with a USB but not charge the batteries. I occasionally use a stand alone, rechargeable power source for mine.
