Key takeaway
- Get the main idea fast and scan headings for what matters.
- One clear next step: decide what you must power.
- Skip details you don’t need and remember the core point: pick the right generator for your needs.
Choose the right generator type for your needs
Pick a generator that matches what you actually need — power for tools, a few appliances, or sensitive electronics. Factor noise, portability, budget, and whether you’ll run laptops or medical gear.
- Portable generator: Best for raw watts on a budget — tailgates, job sites, short home outages. Simple setup and high wattage, but louder and rougher for sensitive electronics.
- Inverter generator: Best for laptops, phones, TVs, and medical devices. Produces clean, stable power with low harmonic distortion, quieter and more fuel-efficient. Often lighter and can be linked in parallel for more power. Cost per watt is higher.
Tip: If you plan to run a laptop, CPAP, or camera gear, choose an inverter — it protects sensitive devices.
Quick comparison
| Feature | Portable Generator | Inverter Generator |
|---|---|---|
| Noise | Louder | Quieter |

| Price per watt | Lower | Higher |
| Portability | Heavier | Lighter |
| Best use | Job sites, heavy tools | Camping, electronics, RVs |
How to size a generator for your home and devices
You want a generator that handles your needs without wasting money. For each appliance know two numbers: running watts and starting (surge) watts. Motors (fridges, ACs, pumps) draw higher startup power.
How to size:
- List every device you want to run.
- Note running watts and starting watts (if any).
- Add all running watts = total running watts.
- Find the single highest starting watt value.
- Minimum starting capacity = total running watts highest starting surge.
- Add a 20% safety margin.
If you lack exact specs, use typical values and add the 20% margin.
| Appliance | Running watts (typical) | Starting watts (typical) |
|---|---|---|
| Refrigerator | 700 | 2200 |
| Sump pump | 800 | 2500 |
| Window AC (1 ton) | 3500 | 6000 |
| Lights & small electronics | 600 | — |
| Example total running | 5600 | |
| Highest single start (example) | 6000 | |
| Minimum generator size (example) | 5600 running / 11600 starting |
Backup generator vs whole-house standby
- Backup/portable: Good for a few circuits (fridge, lights, furnace fan). Connect via cords or a manual transfer switch.
- Whole-house standby: Permanently installed with an automatic transfer switch, rated in kW. For full-house coverage you may need 10–20 kW or more. Professional sizing and installation required.
Quick rule: Want everything powered? Plan for whole-house standby. Only need essentials? A backup generator will save money.
Easy sizing steps recap:
- List essentials, estimate running and starting watts, add largest start to running total, apply 20% buffer, pick a unit with those ratings. For whole-house, get a professional load calculation.
Understand generator fuel consumption and run time
Know how much fuel a generator uses and how long it will run.
Typical fuel burn at ~50% load
| Fuel | Typical burn (gal/hr) | Note |
|---|---|---|
| Gasoline | 0.6–1.5 | Common for portable units; cheaper up front but burns faster |
| Diesel | 0.4–1.2 | More efficient and better for long runs |
| Propane | 1.0–2.0 (propane gallons) | Stores well and clean-burning but uses more volume |
Estimate runtime:
Runtime (hours) = Tank capacity ÷ Burn rate
Examples:
- Small portable (gas): 5 gal tank ÷ 1.0 gal/hr = 5 hours
- Standby diesel: 20 gal ÷ 0.8 gal/hr = 25 hours
Load estimates:
- Low (~25%): ~30–60% of 50% burn rate
- Medium (~50%): use table values
- Full (~100%): ~1.6–2.0× the 50% burn rate
Fuel planning tips:
- Check fuel before an outage; keep a 20–30% buffer.
- Store fuel safely, rotate every few months.
- For propane, plan extra tanks or refill access.
- Prefer diesel or larger tanks for long outages.
- Test-run your generator monthly at realistic loads.
Safety: Store fuel away from living spaces and follow local rules.
Follow generator maintenance tips to keep your unit ready
Routine checks keep a generator reliable.
Monthly or per-run tasks:
- Oil: Check level every 25 hours of run time or monthly if idle. Change if dirty or low.
- Air filter: Inspect monthly and after dusty use; replace if clogged.
- Spark plug: Check every 100 hours or yearly; replace if burned or fouled.
- Battery: Inspect terminals and charge monthly; clean corrosion and replace every 3–5 years.
Safety: Always switch the unit off, disconnect the spark plug, and let the engine cool before work.
Annual service and load testing:
- Schedule annual service with an authorized technician to change fluids, inspect controls, and replace worn parts.
- Do a load test once a year to simulate real demand and check the automatic transfer switch.
- Check fuel and lines annually; drain old gasoline or use stabilizer.
Simple maintenance schedule:
| Frequency | Task |
|---|---|
| Weekly | Visual check — leaks, loose parts, fuel level |
| Monthly | Check oil, air filter, battery charge |
| Every 6 months | Change oil (per manual), clean battery terminals |
| Annually | Full service load test by a pro |
Keep a log of dates and notes; store basic spares (oil, filter, spark plug, terminal brush).

Know generator installation cost and what affects price
Installing a standby generator can range widely. Expect anywhere from a few thousand to tens of thousands depending on unit size, transfer switch, and site work.
| Component | Typical cost (USD) |
|---|---|
| Standby unit (whole-house) | $4,000–$12,000 |
| Transfer switch | $500–$3,000 |
| Site prep (pad, concrete) | $300–$2,000 |
| Fuel hookup (gas/propane) | $200–$2,500 |
| Wiring & breakers | $500–$3,000 |
| Labor / electrician & plumber | $800–$4,000 |
