Check continuous power output, surge ratings, inverter losses, battery condition and each appliance's actual consumption. Refrigerator compressors draw intermittent power and may need a higher start-up rating.

| ProductThe manufacturer and model of the battery system. Some listings are bundles including extra batteries, so compare exactly what is included. | TypePortable stations have built-in sockets for appliances. Home/balcony storage is designed for more permanent energy storage; UK grid connection must be separately verified. | CapacityNominal energy storage in watt-hours (Wh). 1,000 Wh = 1 kWh. Actual usable energy is lower due to conversion losses and reserve capacity. Bundles may include extra modules. | PriceObserved UK product price for the stated configuration. This is not a live quote; check whether VAT, extra batteries, solar panels and delivery are included. | £/kWhUpfront price divided by nominal stored energy in kWh. Lower is cheaper per unit of nominal storage, but does not account for efficiency, cycles, warranty or installation. | AC outputMaximum continuous power in watts available from AC sockets or the specified inverter output. This is power, not energy: a 1,000 W appliance uses roughly 1 kWh per hour. | Buy / viewOpens an Amazon UK listing or search. Confirm the exact model, bundle, stock and current price before buying.

Portable stations should power appliances through the outlets intended by their manufacturer. Never backfeed a home socket with a double-ended cable. Grid-tied solar normally disconnects during a power cut without approved backup equipment. Qualifying UK plug-in solar rules do not automatically validate battery-equipped balcony systems. Consult a competent installer for household-circuit and grid-connected systems.
