Our take on the PowerSmart 2500W Portable Inverter Gas Generator

The PowerSmart 2500W is a gas-powered portable inverter generator rated at 1900W continuous and 2500W peak, with a 1.05-gallon tank that runs about 5.5 hours at half load. It stands out for a built-in CO sensor, low-oil shutdown, overload protection and parallel capability, plus five outlets including USB and DC. At 56 dBA it is quiet enough for campsites and tailgates. Its best new price is $309.99 at Walmart as of November 5, 2026, the low end of what it has recently sold for.

Pros
  • Inverter output is clean enough for phones, laptops and TVs
  • Built-in CO-Detect sensor shuts the unit down if carbon monoxide builds up
  • Quiet for its class at 56 dBA
  • Parallel port lets you pair a second unit for more power
  • Five outlets cover AC, USB and DC devices at once
Cons
  • 1900W continuous won't start most air conditioners or large power tools
  • 1.05-gallon tank means frequent refueling under heavy load
  • Spec sheet lists 50 Hz frequency, which is unusual for a 120V US unit and worth confirming
  • Gas only, with no propane option
  • Heavier and bulkier than battery power stations of similar output

Questions and answers

Can the PowerSmart 2500W run a refrigerator?
It can run a typical full-size fridge drawing under 1900W continuous, but the startup surge may exceed 2500W peak. Check your fridge's surge rating before relying on it.

What comes in the box?
The generator, a spark plug sleeve, a 2-in-1 cross batch tool and a funnel.
