Today I Learned: Portable Generators are NOT Standby Generators

You know portable generators... size of huge toolbox / large wheelbarrow (about 200 pounds), add fuel and it can power up your home for a short time... Costs about 1000 USD. 

Turns out the "short time" is 8-12 hours, which is the run-time based on their fuel consumption and their fuel tank size. 

And you are NOT supposed to run it past 50 hours (after which, you HAVE to change the oil). Failure to do so will likely damage the engine.  

Given that most of these only runs for 8-12 hours (based on fuel consumption and fuel tank capacity) that should not be a problem... Unless, of course, you were in a multi-day blackout like the one Texas endured not too long ago in 2021, and you can't really be bothered to change the oil when the fuel ran out at night. 

The solution is a "standby generator", which is quite a bit larger, and comes with a much larger fuel tank... and they are actually diesel, not gas or LNG. They are obviously more expensive, but they are designed to run for days at a time.
