Power bank vs power station - Help me
I see this on Amazon,
https://www.amazon.com/Jackery-Portable-Generator-Explorer-E...
I believe it’s got enough power to power a small fountain water pump, yet, I’m wondering if there is a smaller device that will give me around 4
hours of run time for my condenser pump.
I know nothing about calculating values and that is the question I’m hoping to have answered by this thread. Thank you

Again, you need to give us a wattage and a voltage, of the pump. Without those no one can say anything.

You can buy 12v fountain pumps and a deep cycle 12v battery a lot cheaper than that.
pump $16 0.3 amp 12v 3.6w 9.8ft lift

battery $40 20Ahr

That pair will do fine, throw in a battery charger for another $20 and you are all set.
You don't want to drain a lead acid battery below 11 volts.
You can generally get 1/2 of the rated value out of a battery at 11 volts.
which for that pair will give you close to 30 hours of run time.

Then, after you follow macckone's advice, you spend half the money you just saved on some aliexpress glassware, and stop fooling around with pvc tubes
in plastic bottles. Maybe you will actually distill something one day.
