CPO via eBay is selling the Quip-All 2,200 Watt Gas Portable Inverter Generator (CARB) 2200I for $329.99. Shipping is free.
This generator has parallel capability to plug 2 of them together and double the running output to ~3000W. Since it appears to be a re-branded PowerMate, you can use Powermate's parallel kit found here: https://www.electricgeneratorsdir...77255.html
Judging by the connectors, this one from Home Depot would also work: http://www.homedepot.com/p/Invert.../203695188
The parallel kit gives you (1) L5-30R outlet and an RV outlet.
CPO does not state the warranty, but they say for full warranty details to contact them. You can also buy Assurant warranties as follows:
1-year protection $6.99
2-year protection $13.49
3-year protection $19.98
I personally have no experience with this "re-brand" brand. It is CPO's exclusive re-brand of the PowerMate. The Duromax is also a re-brand of the PowerMate. For someone in a bind due to the recent hurricane and subsequent power outages, this could be a great opportunity to get something on the cheap side. For further protection, one could buy one of the warranties above and have their credit card add 1 year on top of the extended warranty. Amex and others do this. Citibank will add 2 years on top which is even better than Amex.
