Portable Power Station Runtime Calculator

Enter your battery and appliances for a realistic runtime estimate.

1. Power station setup

Battery capacity Listed on the power station

Battery health Use 100% if new

Output efficiency AC is often 80–90%

Battery reserve Capacity left unused

2. Appliances

Important: Make sure your power station can handle each appliance’s running watts and startup surge. This calculator estimates energy runtime, not output compatibility.

Estimate only. Formula: capacity × battery health × (1 − reserve) × efficiency ÷ average load.
