Overall reviewers generally rate Powermate generators highly on Amazon.com and rave about ease of use, sturdy quality build and an easy assembly process. Some negative points reviewers mention include not being able to operate the generator in the rain, that it is very loud and that some manufacturers rate generators at peak power ratings, not continuous power ratings.
As of 2015, many reviewers note that the Powermate generators are easy to start and work exactly as expected, with one review stating the product powered a moderate load for 12 hours. Another review says the wheels and legs are easy to install with clear instructions, but the negative cable is slightly difficult to connect to the battery. One other customer states that the generator ran continuously for 72 hours during a power outage powering two furnaces, two refrigerators, and landscape and security lighting, but notes that it uses a lot of gas when running non-stop.
Another reviewer on Amazon.com notes that even though the generator functions well, a few things to consider are that it’s loud and that owners should buy oil before the generator’s first use and cover the generator when it rains. Additionally, a reviewer warns to shut off the fuel valve before turning off the power switch as the generator may backfire, which is a fire hazard.
