Too late to ask this because I already ordered it. However there are some appliances that require a high starting Amp. So can this generator start a refrigerator?
1 answer-
ProductExpert6· 3 years ago
A refrigerator would require 2200 watts to start and 700 watts to run it. This generator would be able to start a refrigerator.
