How to size the right generator for your home

  1. 1
    List your must-run appliances

    Write down what absolutely needs power during an outage: refrigerator, a few lights, phone/laptop chargers, maybe a sump pump or CPAP machine. Skip anything that's a comfort rather than a necessity for the first plan.

  2. 2
    Add up running watts, then check surge watts

    Appliance labels or manuals list running (rated) watts and startup (surge) watts. Motors like fridges and sump pumps spike briefly at startup, so your generator's peak wattage needs headroom above your steady-state total.

  3. 3
    Decide between inverter and conventional generators

    Inverter generators produce cleaner, more stable power safe for sensitive electronics, and run quieter — ideal for small loads. Conventional generators are usually cheaper per watt and better suited to higher-wattage whole-home or job-site use.

  4. 4
    Consider fuel type and runtime

    Gasoline models are common and easy to refuel, propane burns cleaner and stores longer, and dual-fuel models offer flexibility. Check the tank size and runtime at 50% load, since that's a more realistic outage scenario than max load.

  5. 5
    Plan for safe placement and ventilation

    Portable generators must run outdoors, well away from windows and doors, due to carbon monoxide risk. Factor this into your buying decision if you have a small yard, a shared wall, or limited outdoor space.

  6. 6
    Check for CO safety shutoff and outlet types

    Look for a built-in carbon monoxide detection shutoff feature, plus the outlet types you'll actually use — a transfer-switch-ready outlet if you plan to hardwire into your panel, or simple household outlets for extension cords.

Portable generator do's and don'ts

Do
  • Run the generator outdoors, at least 20 feet from doors and windows
  • Let the engine cool before refueling to avoid fire risk
  • Test-run a new generator before an emergency actually happens
  • Use heavy-duty, outdoor-rated extension cords rated for the load
Avoid
  • Never run a generator in a garage, even with the door open
  • Don't plug a generator directly into a wall outlet without a proper transfer switch
  • Don't overload the generator beyond its rated running watts
  • Don't store fuel near the generator or indoors

The verdict

There's no single 'best' generator — there's the right size for your specific must-run appliances and budget. Small households wanting quiet, clean backup for a fridge and electronics should look at compact inverter models; homes wanting to run more circuits or a sump pump need mid-size conventional or dual-fuel units; and anyone wanting near-whole-house coverage should size up to a larger conventional generator paired with a transfer switch. Buy based on your wattage math, not the biggest number on the box.

FAQ

What size generator do I need to power my whole house?

It depends on your home's total electrical load, but many households can cover essentials — fridge, lights, some outlets, a sump pump — with 3,000 to 5,000 running watts. True whole-house coverage for central AC and all circuits typically requires a larger unit, often paired with a transfer switch installed by an electrician.

Is an inverter generator worth the extra cost?

If you plan to power laptops, phones, or other sensitive electronics, yes — inverter generators produce cleaner, more stable power and run quieter. For simpler loads like lights and a fridge, a conventional generator can be a more budget-friendly choice.

Can I run a portable generator in my garage during a storm?

No. Portable generators produce carbon monoxide and must run outdoors, away from doors, windows, and vents, even during bad weather. Indoor or garage use, even with doors open, has been linked to carbon monoxide poisoning.

Do I need a transfer switch?

If you want to power hardwired circuits (like a furnace blower or well pump) instead of just plugging appliances directly into the generator, a transfer switch installed by a licensed electrician is the safe way to do it and prevents backfeeding electricity into utility lines.
