Anker SOLIX C300 Portable Power Station Review

The Anker SOLIX C300 sits in the highly competitive 'tool' and 'outdoor power' category, retailing around the £220 mark. It is designed to bridge the gap between small power banks and massive home batteries. Built by AnkerDirect UK, it prioritises build quality and charging speed, offering a versatile range of UK AC outlets and high-wattage USB-C ports to keep modern electronics running during blackouts or travel.

In actual household use, this unit excels at keeping a home office running during a local power cut, easily handling a laptop, monitor, and router for several hours. Its LiFePO4 battery chemistry is a major plus, offering a significantly longer lifespan than cheaper lithium-ion alternatives. However, users should note that high-draw appliances like kettles or hair dryers will quickly exceed its wattage limits.

Direct energy savings are modest, as this is primarily a storage device rather than a generator. However, when paired with solar accessories (sold separately), it can be used to harvest free energy for charging small devices, potentially saving a few pounds a year on your electricity bill while providing invaluable security during Peak Load events or outages.

Essentially zero installation required. It is a 'plug and play' device that charges via a standard UK wall socket or compatible solar panels.

Negligible. Charging from the grid at standard UK rates (approx. 24.5p/kWh) costs roughly 7-8p for a full cycle, which can then power a smartphone for over a week.
