How to Estimate Power Usage

To get an idea of how long a device can run on a Portable Power Station, you can use a simple calculation. Please note, this is only an estimate, as real-world usage can vary based on efficiency and other factors.

Estimated Usage Time (in hours) = Power Station Capacity (Wh) ÷ Device Power Usage (W)

 

Examples:

Power Station Capacity

Device Power Usage

Estimated Run Time

1200Wh

400W

1200 ÷ 400 = 3 hours

1000Wh

250W

1000 ÷ 250 = 4 hours

500Wh

100W

500 ÷ 100 = 5 hours

 

Keep in mind:

  • This is a rough estimate - actual performance may be shorter or longer depending on real usage conditions.
  • Ensure your device power usage is below the max rated watts the power station can ouput.
  • Always allow some buffer in your calculations to account for energy loss or variations in power draw.
  • Some Power Stations can use Expansion Batteries to extend their capacity.
