Blackout Buddy Emergency Power Supply

The Blackout Buddy is an automatic backup power supply that guards your fridge. It sits between your wall outlet and your fridge, stays charged, and switches over the instant the grid goes down, even when you're not home. With 1,030 Wh of stored power and a safe lithium-iron-phosphate (LiFePO4) battery, it keeps your food cold and essentials running through an outage.

With 1,030 Wh of stored power, it can cycle a typical fridge for up to 34 hours on a full charge. It handles up to 600 watts continuous (1,200 watts surge), so check that your fridge stays under that limit. Run times are approximate and vary by appliance and usage. A fridge cycles on and off, so it draws power only part of the time. Per CDC guidance, a closed fridge keeps food safe for about 4 hours, a full freezer about 48 hours; starting with a cold appliance and cycling power helps stretch your run time. See the footnote for details.

Phones, laptops, lights, CPAP machines, fans and small appliances, plus larger items depending on the model. It handles up to 600 watts of continuous power (1,200 watts peak), so anything that stays under that limit will run. Check the wattage on your device's label and keep your total under the generator's limit.

Yes. Unlike gas generators, it produces no fumes or carbon monoxide, so it's designed for safe indoor use. That makes it a practical way to keep a fridge, CPAP machine, lights and electronics running inside during a blackout. Follow the included instructions for safe charging and ventilation.

It recharges automatically through the wall outlet it's plugged into, staying topped off while it monitors the grid. It's also compatible with 4Patriots 100-watt or 200-watt solar panels (sold separately) so you can refill it from the sun during a longer outage. Solar charge times assume good sun; a wall outlet is faster and is the best choice when it's available.

Yes. Thanks to pass-through charging, you can power your devices at the same time the unit is recharging, so you don't have to choose between topping it off and keeping your essentials running. It's handy during a long outage when you're recharging by solar during the day.

Charge it fully before a storm so you're ready no matter the forecast. Solar charging slows on cloudy days, which is exactly why you can also top it off from a wall outlet ahead of time. Once it's charged, it stores that power until you need it, rain or shine.

It's built for the long haul, rated for 4,000 blackouts. The lithium-iron-phosphate (LiFePO4) battery holds up to repeated draining and recharging while keeping most of its capacity. Battery performance varies based on charging and usage conditions. See the footnote for details.

It uses a lithium-iron-phosphate (LiFePO4) battery. This chemistry is prized for being safe and stable, running in hot or cold temperatures, and lasting far longer than older lithium-ion batteries. Battery performance varies based on charging and usage conditions. See the footnote for details.

Focus on four things: capacity (watt-hours, how long it runs your gear), continuous and peak wattage (what it can power and start), battery type and lifespan (LiFePO4 lasts longest and is safe indoors), and recharging options (wall, solar and car). Match the wattage to the appliances you most want to keep running, and favor fume-free units you can use inside.
