Does it work on battery ? or it needs a power source

you need a power source .. this tank is very tiny ... do not buy something this small

No batteries.. It needs power outlet... The near thing about it is the pump comes with two out puts. One for the filter and one for the bubbles.

You will require 2 outlets to power it.. one for the air pump.. and one for the lights.

No my friend, it is no battery powered, you need to connect it to electricity.

You need to hook it to a 12 volt DC source like a battery or power supply for this to work.

The camera does need a power source. I did not use the power adapter because I connect the camera to my existing video surveillance system. I hope this answers your question.

Yes, you have to plug into electrical outlet to have it work, there is no internal battery.

The power supply is an option. It uses a 9 volt battery (not supplied - no surprise there). When the power supply is used, the battery functions as a back-up.

I does need a power source in order to operate. Find an object to hind the power cable i.e. plant, bookshelf, vinyl tube...There is no battery in the camera.

No this doesn't run on battery. We need to connect it to plug whenever we want to play.

It will work for several minutes running off a charged battery however for intended and extended use it must be plugged into an electrical outlet.

It uses a small, onboard battery for its power source. I believe it's a AAA battery - should say in the description.

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

You must supply a power source, so battery backup would be a good option to think about.

It's battery operated. But don't worry, it doesn't work with batteries, either.

AC power is the primary source and the battery is the backup. FYI I used it for two months with just the battery and it worked fine.

No, it does not need a battery. I did not put a battery in mine and it worked fine.
