What is a portable power station size calculator?

This Portable Power Station Size Calculator is a simple yet powerful tool that helps you determine the ideal power station capacity for your needs. By inputting your devices’ total power consumption, desired runtime, and power station efficiency, you’ll get an accurate estimate of the required capacity in Watt-Hours (Wh).

How many Watts Does a portable power station use?

Every portable power station comes with a rated capacity, typically measured in watt-hours (Wh). This figure represents the total amount of energy stored in the battery. For example, an OUPES portable power station with a 1,000Wh capacity theoretically supplies 1,000 watts for one hour or 100 watts for ten hours.

How much power does an oupes portable power station use?

For example, an OUPES portable power station with a 1,000Wh capacity theoretically supplies 1,000 watts for one hour or 100 watts for ten hours. However, this is only the theoretical limit—real-world usage often differs. To estimate runtime, you must first determine the power draw of your devices.

How much power does a power station need?

This formula calculates the minimum capacity (in Wh) your power station needs to deliver enough power to the devices over the specified runtime. Example 1: “You need a power station with at least 705.88 Wh capacity. Example 2: “You need a power station with at least 1466.67 Wh capacity.

How do I calculate the required power station size?

The calculator uses the following formula to determine the required power station size: Required Capacity (Wh)=Device Power (W)×Runtime (hours)EfficiencyRequired Capacity (Wh)=EfficiencyDevice Power (W)×Runtime (hours) Where: Device Power (W): The total power consumption of all devices in watts.

What is the efficiencies of a portable power station?

Most have efficiencies between 0.8 (80%) and 0.9 (90%). If you’re unsure, input 0.85 (85%) as a standard value. The tool will compute the required capacity (in Watt-Hours) for the portable power station. The result will tell you the minimum capacity (in Wh) needed for your specific setup and runtime.
