Questions and answers

Is the Ryobi RY906500S worth it?
At $750 at eBay as of November 4, 2026, it is a low price for 6,500 running watts with CO shutdown. You give up electric start and quiet operation at that price.
How does it compare with the previous Ryobi 6,500-watt model?
The main addition is the CO shutdown sensor, which shuts the engine off when carbon monoxide rises. Output, tank size and recoil start carry over.
Can it run a house during an outage?
It can carry essentials like a fridge, furnace fan and lights through its 120V outlets, or a transfer switch through the 240V 30A twist-lock. It will not run central AC or an electric range.
Does it have electric start?
No. It is recoil pull start only, so you need to pull the cord by hand each time.
How loud is it?
Ryobi rates it at 72.3 dB. That is normal for an open-frame generator but loud enough to bother close neighbors.
When is it cheapest?
Generator prices tend to dip outside storm season and around fall sales. The $750 eBay price as of November 4, 2026 is the only new listing found, so compare it against that.
