Power stations are becoming a staple of any smart home setup, since you’ll need to keep all the essential tech running when the grid goes down. If you’re looking for a reliable home backup solution, Anker SOLIX, the go-to favorite for charging, power, and device accessories, has something that fits the bill.

The Anker SOLIX S2000 is the debut model in the new S-Series, built on a foundation of long-lasting power and living up to its slogan, ‘Long-lasting Power Redefined,’ to serve as more than just a standard home backup solution. It can keep a full-size refrigerator running for up to 35 hours on a single charge, and that’s just one of its many highlights. Even though the S2000 launched very recently, Anker is already offering a massive discount on one of the longest-lasting 2 kWh home backup options around. Here’s what you need to know.

Anker SOLIX is one of the biggest names in battery storage and power delivery, and the S-Series takes that expertise to the next level. While a lot of power stations try to do too much, from being a camping battery to a job-site tool, the S-Series is designed exclusively for long-lasting home backup.

The key selling point here is the runtime, since losing power at home usually involves an emergency that can take hours, or even days, to fix. Anker calls it “True Runtime” and focuses less on the spec sheet and more on what it can deliver.

While all batteries lose energy to idle drain and conversion losses before it reaches your gadgets, the Anker SOLIX S2000 is built to deliver more of what it stores. This translates into about 20% more usable runtime than competing 2kWh units, and the S2000 carries TÜV SÜD A+ Runtime certification, the highest rating available.

The number Anker showcases is 35 hours of continuous refrigerator backup on a single charge. That is a long time, long enough to ride out most outages without losing a freezer full of food.

The technology that makes that runtime possible is OptiSave™. It is a system-level approach to reducing wasted energy, specifically targeting two often-overlooked areas: idle power consumption and light-load efficiency.
