Guides
Practical guides to backup power for real situations: how long a power station runs a refrigerator, a CPAP, a sump pump or a space heater, how to size one for your home, and what to do before and during an outage. Every guide shows the formula and works through an example, so you can check the math or plug in your own numbers. Guides that touch on health are reviewed by a physician.
