One obvious difference resides in their name; a portable generator can be carried along wherever you require power, whether it is a campsite or a job site.

On the other hand, the standby generators are made to sit in one place, and they don’t have any handles or wheels to move them. They are hardwired to the electric circuits of the house.

When it comes to the portable generator, then they need to be run outside. If used inside, then the accumulation of the exhaust from these generators can turn out to be fatal if breathed in.

If they are outside, there is a risk of theft.

But for the standby generators, due to their heavyweight, they don’t appeal to thieves much. Other than that, if you want to run the portable generator as a backup generator, then you will have to first accumulate the fuel, and the fuel tends to evaporate.

This doesn’t always make it possible to have fresh fuel. While for the standby generator, you can directly connect them with the existing propane or natural gas supply to your house, and it will be ready anytime you want it to work.
