Power Station Runtime Calculator

The only question that matters before you buy: will it actually run my stuff? Pick a size, check your gear, get the real number.

Battery capacity
1,000 Wh
What do you need to power?
Estimated runtime
8.3 hours
running 3 devices (200W nameplate · ~103W effective)
Fridges, freezers & AC cycle on/off — we use their real duty cycle, so runtime is longer than raw watts suggest.
Just the fridge alone on this battery: 16.2 hours

For your load, we'd aim for a 1,000Wh station.
