What kind of power source do I need to run this mini pump?

You can plug it into any standard 5V USB port, like a phone charger, power bank, or computer. It also runs on 3V power, meaning you can wire it to a 2x AA battery pack. It only draws about 0.2 to 0.4 amps, making it very energy efficient.

How high can this pump push water, and what size tubing does it take?

This micro pump has a maximum lift height of 0.5 to 1.0 meter. It pumps between 80 to 150 liters per hour, which is perfect for small desktop setups. For the water outlet, you will need tubing with a 6mm to 8mm outer diameter.

Does this pump have to be completely underwater to work safely?

Yes, this is a fully submersible pump and must be underwater during operation. You can safely submerge it up to 0.5 meters deep in your fountain or tank. Operating it dry can damage the micro motor, so keep it covered.
