What happened
As winter storms have rolled through parts of the country, producing heavy snow, rain and some outages, Anker’s 521 PowerHouse portable backup battery has returned to the spotlight. The unit, which the source says can keep up to six devices powered, is currently priced at $129.99 — a discount the original report describes as roughly half off. The article notes a recent example from California in which a brief power loss underscored the usefulness of a small, transportable power station for keeping phones and other essential gear running. Specific technical details such as battery capacity, port types, run time and how long the sale will last are not provided in the source. The reporting frames the 521 PowerHouse as a practical purchase for consumers seeking extra resilience during storm-driven outages.
