Yamaha s unit has our favorite control panel. Everything is laid out in a nice line towards the top of the machine. The receptacles and switches are well-spaced for quick and easy access. And the frame sufficiently protects the switches so they won t be broken by a falling shovel in the van, a snag while carrying the unit, or any of the other million things that have broken switches on my jobsite generators. All of these machines vibrate enough to work their receptacle and switch screws loose, so they can use any protection designers can give them.
Compact stature is important for mobility, storage, and quick access.
We liked the compact Honda, Yamaha, and Mitsubishi units the best. Most people won t check a generator s oil, or they ll think someone else has done it. Air filters that can be cleaned on site with compressed air like those on the Generac, Desa, Campbell-Hausfeld, and Winco models are also great for keeping these power plants running smoothly. The other units we tested require solvent to clean debris from their filters, which has to be done in the shop to avoid spilling solvents. Generac makes a highly serviceable unit.
