Don't let the size fool you

Why more volts = more power

Think of electricity like water flowing through a hose

Voltage (V) = water pressure Voltage is the force that pushes electricity through a wire—just like pressure pushes water through a hose.
→ Higher voltage = more push = more power available to the motor.

Current (A) = water flow rate Amps measure how much electricity is flowing, like how many liters of water per second flow through a hose.
→ More amps = more flow = more work gets done

Resistance (Ohm) = hose diameter Resistance is the friction or difficulty electricity faces as it flows—just like a narrow hose slows down water.
→ High resistance = more energy lost = less efficiency

Power (W) = pressure × flow Watts are the actual power your tool uses. It’s calculated by multiplying V × A = W.
→ Think of it as the total force of water hitting a waterwheel

Battery capacity (Ah) = water tank size Ah tells you how much electricity is stored in the battery—like the size of a water tank connected to the hose.
→ Higher Ah = longer runtime

Think of voltage like water pressure in a hose. The higher the voltage, the more force the electricity has—so the motor gets more power.
