Please only use Watts to measure power!

Joules and watts are technically different. In fact it's not complicated. 

Watts are used to measure the power you can create per second. 

Joules are used to measure the quantity of power stored. 

If you have a 4000J battery (like a big transformer) and a 800W generator. You will need 5 seconds to charge it. 

Now for a 40kJ battery with 3 hydrogen generators. That is 2400W. You'll need around 17 seconds to charge it. 

Joules and watts are converted to a 1:1 ratio. I was lost before but when you get the hang of it, it's more clear ^^

Watts = Joules per second.
If something requires 120W then it will consume 120J every second. 40 000J battery may supply 120W device for roughly 333 sec. (40000 / 120).

Power is measured in watts.  Energy is measured in Joules.  They are different things and thus, use different units.

 

granted the ingame info is mixed up about it on several cases too.

take this picture for instance it isn't power but energy.
