The two options, in plain terms
A portable generator is a unit you store in the garage and roll out when the power goes down. Connected through an inlet box and interlock, it powers your selected essential circuits. You start it, plug in one cord, and flip a few breakers. A standby generator is permanently installed outside, runs on natural gas or propane, and starts on its own within seconds of an outage to keep far more of the home running automatically. Both are legitimate. They just sit at very different price points and lifestyles.
The cost gap is the headline
This is the number most people are surprised by:
| Portable + inlet | Standby generator | |
|---|---|---|
| Typical install cost | $1,197 to $1,497 | $12,000 to $20,000+ |
| The generator itself | You own it or buy it ($500 to $1,500) | Included in the install |
| Starts | Manually, you roll it out | Automatically, on its own |
| Fuel | Gasoline you store | Natural gas or propane line |
| What it powers | Selected essential circuits | Far more of the home at once |
| Maintenance | Minimal, occasional run | Annual service contract |
| Noise + footprint | Small, stored away | A permanent pad-mounted unit |
Who the portable route fits
For most homes, the inlet-and-interlock route is the smart buy. It fits you if:
- You want reliable backup for the essentials, fridge, heat, well pump, lights, internet, during occasional outages.
- You would rather spend a flat $1,197 to $1,497 than five figures.
- You do not mind being home to start the generator when the power drops.
- You already own a portable, or are happy to buy one for a few hundred dollars.
Who the standby route fits
We will be straight: a standby is the better fit for some homes. Consider it if:
- You are away from home often and need backup to kick in with no one there.
- You have medical equipment or other loads that genuinely cannot lose power.
- You face frequent, multi-day outages and want hands-off, automatic coverage of much of the house.
- The five-figure budget is not the deciding factor for you.
What the affordable route costs
- Weatherproof inlet box (30A or 50A)
- Listed interlock kit for your panel
- Generator breaker installed
- All wiring, conduit, weatherproofing
- The permit and inspection
- One-day labor, no return trips
The honest scope
The portable route connects the generator you own to power your selected essential circuits through your panel. It is not automatic and it is not a whole-home standby generator, and for most families that trade, a few thousand dollars saved for a small bit of hands-on effort during a rare outage, is exactly the right one.
