does it works on battery only or through direct current also?

Marina "Battery-Operated' Air Pump. As stated in the name, it is battery only. Uses 2 D Cells. Primarily for use when electricty goes out or for transporting fish.

Considering batteries are DC energy...you should be able to make the necessary modifications to the hardware in order to expand on the input methods. Alternating Current(Household outlet); however, would be completely different. Requiring a relay of some kind.

Battery only, it is meant as an emergency pump for when the electric power off.

Battery only. And believe me, it came in sooo handy when the power went out twice! I believe it saved the life of my fish. I love it, and I have three of them--one for each of my tanks.

It works without batteries. When you pierce the wire insulation, thats hiw it gets it's power. The alligator clamp opens and you place it on metal for ground. That nakes the connection for a circuut wich activates the light.

I don't know - as I understand it, connections are made directly to the battery to keep it at full power. If your battery supplies power to the inverter then I'd suppose you have power at the inverter. A direct connection to the inverter??? If you find that it works I'd like to know. good luck.

Yes, it does work on battery power. I just installed four of these in my house and turned off the circuit breaker, to have them work on battery only. Tested one & they all went off as they are suppose too.

We only have it plugged in. As far as we cal tell it does not accept batteries.

Yes it works both ways. This is not my first drill I decided to try an electric drill rather than one with a battery. It is easier to work and a bit less heavy

It does not use batteries. I CANNOT be used on household current. It is for automotive use ONLY.

When the battery is switched to "off" it will run through the power cord only and not use the battery but won't charge the battery either. The battery is only used or charged when switched to "on".

The solar panel is the only way for it to work. The solar panel is the only way to charge the batteries. You plug it in and leave it alone.

It runs on the DC power of your vehicle's batteery . No additional battery required.

No. It only converts DC power into AC power. The batteryour is your electrical source.

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.

It does not work on batteries. It must be plugged into an electrical socket.

12v so battery only. I use it mostly for adding air to my trailer tires and it does a great job. Heck of a lot easier than doing it by hand. Works so well I even had one stolen when I forgot to lock my Suburban.

Just wanted you to know that the wiring on this thing is backward, at least as far as the DC part is concerned. I don't use the AC part. In other words, it only works when you hook your DC input (battery) to the output side, and your output to the side marked "battery." The printed instructions that came with this item is wrong. If you hook it up according to the manual, it will not work.

Since it connects directly to 12V battery, it must only be 12V- I guess if you have a 110-12 voltage reducer? Good luck.

It works from internal battery. Battery charges from external adapter, which consumes INPUT: 120VAC - 60HZ 2WOUTPUT: 4.5VDC - 100maI think that it will be easy to find compatible adapter for 220VAC in RadioShack
