Guides to backup power at home, from portable power stations to whole-home batteries. We explain how to size a system, what the main battery chemistries mean in practice and how long your devices will actually run. Good places to start: home battery backup sizing and cost, LFP vs NMC batteries and our fridge runtime calculator.
LFP and NMC are the two lithium-ion chemistries you will meet in EVs, home batteries and power stations. Here is how they differ on cost, lifespan, safety, range and cold weather, and which one fits your use.
A simple formula, a runtime table for common power station sizes, and practical tips to keep your fridge cold for longer during a power outage.
