Our take on the PowerSmart 3800-Watt Portable Inverter Generator

The PowerSmart 3800-Watt Portable Inverter Generator is a gasoline-powered unit with inverter output, aimed at camping, tailgating and home backup. Inverter design means cleaner power for laptops, phones and sensitive electronics than a conventional open-frame generator. At $349.56 at eBay as of November 5, 2026, it sits at the low end of what 3,800-watt inverter generators typically cost, so it is a budget pick rather than a premium one.

Questions and answers

Is 3,800 watts enough to run a refrigerator?
Yes for most household fridges, which draw well under 2,000 running watts. Check the startup surge on your fridge's label, since compressor startup can briefly exceed the generator's continuous rating.
Can it run a portable air conditioner?
A small 8,000 to 10,000 BTU unit is usually within range, but startup surge matters. Larger RV or central units will overload it.
Is it safe for laptops and phones?
Yes. The inverter output produces clean power suitable for electronics, which is the main reason to choose it over a conventional generator.
Does it run on propane?
No. It is gasoline only, so there is no dual-fuel option.
When is the price lowest?
Generator prices tend to dip outside storm season and during fall clearance. The current best is $349.56 at eBay as of November 5, 2026.
What comes in the box?
Typically the generator, a funnel, tool kit and owner's manual. Confirm the listing contents, since bundles vary by seller.
