Every hurricane season the same debate happens in every Southwest Florida household: spend a couple thousand on a portable generator, or five figures on a whole-house standby? Both answers are right — for different houses. Here’s the honest comparison we give people on the phone.
The Real Difference Isn’t Power. It’s Presence.
A portable makes power. A standby makes decisions. The portable requires you to be home, roll it out, fuel it, run cords or a transfer switch, and babysit it for days. The standby starts itself 10 seconds after FPL drops — whether you’re home, at work, or out of state in July, which is exactly when half of Southwest Florida is.
Where a Portable Wins
- Price — $500–$2,500 buys a lot of capability, especially with an interlock or manual transfer switch professionally installed (a few hundred dollars more, and the only safe way to feed a panel)
- Flexibility — it can go to the hunting camp, the job site, or a neighbor’s house
- Enough for essentials — fridge, fans, phones, some lights, maybe a window AC unit
Where a Standby Wins
- Whole-house coverage — central AC included, which in a Florida August is the whole argument
- Nobody has to be home — it exercises itself weekly and transfers automatically
- No gas cans — it runs on LP or natural gas; no 5 AM fuel-line pilgrimages after a storm
- Insurance-friendly — the house stays cooled and dehumidified, which is what prevents the mold claim
The Numbers Side by Side
Portable: $500–$2,500 for the unit, plus a professionally installed interlock or transfer switch. Standby: $9,000–$20,000+ installed, all-in — unit, pad, gas, electrical, permits. The full breakdown is in our whole-house generator cost guide.
The Dangerous Middle Ground
What we never want to see: a portable backfed into a panel through a dryer cord. It can kill the lineman working your street and it’s how houses burn down. If you go portable, the interlock kit is not optional — it’s the whole difference between a backup plan and a hazard. We install them constantly and cheaply relative to what they prevent.
Which One Is Right for You?
If you evacuate every storm, travel in summer, have medical equipment, or simply refuse to do another August without AC — you’re a standby household; start at our standby generators page. If you shelter in place, are handy, and mostly want the fridge and fans covered, a portable with a proper interlock is a legitimate answer, and we’ll install the switch. Either way: send a request or call 239-372-9426 and we’ll size it honestly.
