Is this pump use battery or alternating current?

You can use either power source. It comes with an AC adapter. I purchased a separate battery pack for travel.

The unit itself doesn't take batteries. But you can purchase an external battery pack for it.

Mine uses 120V. You might want to contact Little Giant Pump to see if they make a 220V model.

It is variable speed pump, which varies the flow. Works great. Saves on energy cost.

I would use 12volt dc relay. NC contacts would run pump during day light hours. Night hours relay would turn on and open contacts to turn pump off.

A controller to insure the battery does not get overcharged. Other than wire, wire nuts etc. that is all you need if the lights and water pump are 12volt. If they run on 110-120 volt, you will need an inverter to change the current from DC to AC.

It is electric. It will not work without cord. It's not battery operated. I detach the cord to refill at sink.

This is strictly electrical. Works great and keeps the water temperature at a comfortable level enabling use of our pool for a much longer period of time than without this pump.

I don't know because I used 3 12v deep cycle batteries with a 55W solar panel charging them. The pump runs off the batteries.

Jay, I have kept the pump in storage so i cannot see it now. But I am in Asia and I need 220v also. So I plugged the pump into an AVR (automatic voltage regulator) that has 110v socket. The AVR normally cost here like $15.

Not too sure, I imagine that if you had a separate way of switching the pump to low/high the timer would run it at either voltage.

yes, it requires a 120v outlet. However the pump itself is just a small thing, I didn't use mine constantly. Just run a extension cord to it and run it overnight every so often.

I use a 12 volt transfer pump installed in one of the 2" tank fittings. I use a battery pack to power the pump when I need it.

It's battery or ac powered. Mine only was used about 6 times before it broke.

The pump is electric. It takes a matter of maybe 30 seconds to a minute to inflate. It works very well!

The best way to power the pump is to use four, six volt batteries wired in series. http://www.zbattery.com/Connecting-Batteries-in-Series-or-Parallel

This pump takes 12 volts, so we got a battery holder that held 8 AA cells. I have no idea what would happen if you tried running it on a lower voltage.

Yes and no The pump runs itself just off battery but, the charger that is hooked to household senses when the battery is discharging and recharges the battery if household power is available.
