What Can I Run on the Briggs & Stratton Q6500 QuietPower Series Inverter Generator?

Let’s talk in real terms. Here’s a breakdown of what you can and can’t run on the Q6500.

Can Run:

mock up of a dining room with sink

  • Refrigerator (including fridge/freezers)
  • Window air conditioners
  • Mid-size central air conditioning
  • TV
  • Dishwasher
  • Washing machine
  • Microwave
  • Central lighting via switchboard
  • Clothes dryer

One of the critical questions is whether you can run central air conditioning on a 6,500-watt generator. The starting watts are an essential consideration, as for central A/C, this will be substantially higher than the running wattage.

Older and larger central A/C systems will probably need more power, but many mid-size central air conditioning systems can use the Q6500.

Can’t Run:

four plugs and their wirings

  • Large central air conditioners
  • An active household using many high-energy applications (such as a clothes dryer) simultaneously
  • Multiple high-energy power tools

If you’re looking to run an entire household on a generator without rationing, you may need to think bigger.

Likewise, a worksite using a large number of power tools at the same time may place the Q6500 under a heavy burden.

Be sure to know what your tools require before choosing a generator.
