Sorry if I came over too mean. @flyex10 welcome to life in the human race. As @2112 says, we learn by making mistakes. Even when we are most definitely adults and should know better, we are still learning. Some of us humans make a living by exploiting those mistakes. For example in my early fifties I couldn't resist buying 18650 size Li-ion batteries with 10,000mAh capacity! Wow, 10,000 mAh! Yes, I was cheated. The actual capacity was twenty times lower. Like I said, check with the forum before you pay the seller.
To be honest, for watering plants a 1W pump may be better than a 100 W pump.
If it is for a plant in the living room, 1 bar pressure and 10 liter/min is not really handy...
0.1 horsepower = about 75W / 5V = 15A.
