Is a portable power station cheaper than a generator?

For occasional outages it often is: no fuel, no oil changes, no maintenance visits. A gas generator looks cheaper upfront but its fuel and upkeep add up over 5 years, especially with frequent or long outages.

How long do portable power stations last?

LiFePO4 stations are typically rated for 3,000-4,000+ charge cycles to 80% capacity — a decade or more of occasional outage use. Gas generators need oil, filters, and exercise runs on a schedule regardless of use.

Power station vs generator: 5-year cost

A gas generator looks cheaper on the shelf — then you buy fuel, oil, and maintenance for five years. Enter your outage pattern and see the real total next to a comparable power station.

Comparable gas generator price $900

Outage hours per year 48 h

Gasoline price $3.50/gal

What the math includes

Gas generators burn roughly 0.75 gal/hour under moderate load, plus about $60/year in oil, filters, and spark plugs, and a $300 replacement budget across five years for wear parts. Power stations cost electricity to recharge (about $0.17/kWh) and nothing else — no oil, no filters, no exercise runs.
