That's one reason why I went with a Honda. The unit has an intelligent voltage regulation control that automatically throttles up or down to accommodate the load that is being placed on the motor. It delivers very clean, stable power which for me is a must. I work from my home (my office is in my house) so I need to know that my computer and other sensitive electronic devices won't get fried. I've owned many Honda products in the past and can attest to their durability and reliability when it really matters the most. It's kind of funny when you see posts on various forums stating that this engine runs "like a Honda" or has many features that are found "on a Honda". The cost differnece between owning a genuine Honda product or a knock off is marginal if you amortize it over several years.
