Backup power guides
Practical answers for planning a power outage at home, each worked through with the same math as the planner and linked to its sources.
How long will a power station run a refrigerator?
About 12 hours on a 1,000Wh station for a typical fridge — and how to get your own fridge's number from its energy label.
Backing up a CPAP with a power station
The humidifier matters more than the station. Sizing from ResMed's published draw, why DC beats AC overnight, and how to rehearse safely.
Backup power for apartments and renters
No generator, no rewiring. What a plug-in power station realistically runs in an apartment, and how to use one safely indoors.
How long will a power station run your appliances?
The formula, a worked example you can check by hand, and why small loads like a router run shorter than the label suggests.
The 1,000Wh class compared: which one for your outage?
DELTA 2, AC180, SOLIX C1000, Explorer 1000 v2 and R1500 side by side: same job, different trade-offs.
How to recharge a portable power station
Wall, solar, car and generator charging compared: ideal full-recharge times for all nine stations we cover, honest sun-hours math, and how recharging during an outage works hour by hour.
