If you’re a weekend warrior with a garage, this is your machine. A 6500-watt generator can handle a circular saw (1500 watts) and a shop vacuum (1000 watts) at the same time. Go ahead, build that deck during the power outage—you’re unstoppable.

It will also power a sump pump if your basement floods. That’s not a fun story, but a very practical one. A 1/3 HP sump pump draws about 800 watts, and the generator starts it easily.
Remember: starting watts are the secret ingredient. Tools and motors need a bigger kick to get going. A 6500-watt generator usually peaks at about 8125 watts, giving you that extra oomph for fridges and pumps.
What You CAN’T Run (And Why That’s Okay)
Let’s be honest so you don’t get disappointed. You cannot run your electric water heater (4500 watts), central air conditioner (5000+ watts), or a large electric oven. That’s okay—you don’t need to turn your home into a hotel.
If you try to run a welder or a RV air conditioner, you might trip the generator. It’s like trying to fit a giraffe into a Mini Cooper—technically possible, but nobody wins. Know your limits.
But here’s the good news: you can run well pumps (1/2 HP uses about 1500 watts) and a small microwave (1000 watts). You can heat up leftovers, take a short shower, and watch movie. That’s a pretty good blackout day.
