Generators
A generator is only useful if it starts when you need it and runs what you actually plug in. We compare portable, inverter and home-backup units on true running wattage, runtime per tank, noise and fuel type, and explain the sizing math so you buy enough power for your fridge, furnace or job site without overpaying.
