The difference between a watt (W) and a watt-hour (Wh) is fundamental to understanding the capabilities of a portable power station:

Watt (W):
A watt is a unit of power.  Watt (W) tells you how much power a device or power station can provide or consume at any given time.  Watts tell you how much power something uses at a moment.

For instance, if a device requires 100 watts to operate, it means it uses 100 watts of power continuously while running.

Think of watts like the speed of a car.  It tells you how fast the power station can deliver energy to your devices right now.  For example, a 100-watt light bulb needs 100-watts of power to stay on.

Watt-hour (Wh):
A watt-hour is a unit of energy.  Watt-hour (Wh) tells you how much energy the power station can store or provide over a period of time.  Watt-hours tell you how long the power will last.

For example, a portable power station with a capacity of 500 watt-hours can theoretically provide 100 watts of power for 5 hours (100W * 5 h = 500 Wh).

Think of watt-hours like the size of a car’s fuel tank.  It tells you how much energy the power station can store and use over time. 

For instance, if a power station has 500 watt-hours, it can power a 100-watt light bulb for 5 hours (100 watt x 5 hours = 500 watt-hour.

Understanding these units helps in selecting the right portable power station for your needs, ensuring it can both power your devices and store enough energy to keep them running for the desired duration.
