Gasoline electric generator 8500 I use it in a food truck, it runs my 12,000 BTU air conditioner, a refrigerator, a 1500-watt heater, and a 700-watt microwave with ease. Approximately 25-liter tank. It has no issues, I changed the oil and it's been inspected. The reason for selling is that the municipality requires a silent generator. Negotiable price, and I won't disagree with a serious buyer.
