A refrigerator’s running wattage does not show how much energy it uses over a full day. Learn how to measure compressor cycling, daily watt-hours and starting demand before choosing backup power.
A fridge-freezer’s running watts cannot predict portable power station runtime on their own. Learn how compressor cycling, starting surge, inverter losses, battery reserves and measured energy use affect the calculation.
Work out the portable power station size you need by separating watt-hours from output watts, allowing for surge demand, conversion losses, reserve capacity and real appliance duty cycles.
A standalone home battery can provide outage backup and shift grid electricity to cheaper periods, but its value depends on usable capacity, inverter output, tariffs, installation and how often you use it.
V2L can let a compatible UK electric car supply selected appliances during a power cut. Learn about vehicle compatibility, adapters, power limits, battery runtime and safe connections.
An electric car may keep essential circuits running during a UK power cut, but only with a compatible bidirectional charger, safe grid isolation and a suitable home installation. Here is what to check.
X2G is an umbrella term for bidirectional EV energy systems. Learn how V2G, V2H, V2B and V2L differ in the UK, and what vehicle, charger and installation compatibility involves.
Learn how to prioritise essential appliances and compare portable power stations, home batteries, generators, solar and EV-based backup for UK power cuts.
