The 4Patriots Blackout Buddy is a slim, automatic backup power system designed primarily to keep refrigerators, freezers, medical equipment, and other essential devices running during a power outage. Its biggest advantage is that you don’t have to be home to activate it: pass-through technology detects a power failure and switches to battery power in just 20 milliseconds. Inside is a 1,030Wh LiFePO4 battery rated for 4,000 lifecycles, delivering 600W of continuous power and up to 1,200W peak. It can power a refrigerator continuously for up to 12 hours or keep one cycling for up to 34 hours, helping protect groceries, medications, and other temperature-sensitive items without the noise, fumes, or manual startup of a traditional generator.

The Blackout Buddy is also designed to stay out of the way. At just 2.5 inches thick, it can stand upright, lie flat, mount to a wall, or tuck behind an appliance. Two pure sine-wave AC outlets provide power, while a detachable magnetic display shows battery level, real-time power consumption, estimated runtime, and solar input. The system recharges from a wall outlet in about 2.1 hours, supports solar charging, and can be expanded by connecting up to four units for 4,120Wh of stored power. Overall, it’s a focused “set it and forget it” backup solution for homeowners who want important appliances protected automatically when the grid goes down.
