How to Calculate Watts (Power) for Your Devices

The Golden Formula:

Watts (W) = Volts (V) × Amps (A)

3 Simple Steps to Check Compatibility:

  1. Find the Specs: Look at the sticker on your device or its power brick. Find the "Output" voltage and amps (e.g., 12V, 5A).
  2. Do the Math: Multiply Volts by Amps to get Watts.
    • Laptop Example: 19V × 4.74A ≈ 90W
    • Phone Example: 5V × 3A = 15W

  3. Check Your Power Station:
    Add up the watts of all devices you want to run (e.g., 90W + 15W = 105W Total). Your power station’s output must exceed this number.
