Anker has taken the covers off the SOLIX S5000, a portable power station that combines a 5,024Wh battery with 4,500W of output.

The Chinese power specialist tells us that it can keep your essential household appliances running for up to two days.

The main selling point is efficiency rather than simply packing more batteries into a larger enclosure. Anker’s OptiSave 2.0 technology is designed to reduce the power consumed by the station itself, allowing more of the stored energy to reach your appliances and devices.

Anker states up to 96% efficiency under a 1,000W load and says the S5000’s idle consumption drops to 8.8W when operating in 120V mode.

If that holds up then it translates into some substantial runtime claims.

With a rated output of 4,500W and peak output of 8,000W, the S5000 is designed to handle more than phones, laptops and a few lights.

According to Anker’s testing, the S5000 can power a refrigerator, Wi-Fi router, coffee maker, lights and charge multiple smartphones for up to 48 hours.

It has both 120V and 240V connections that can supply compatible household appliances, including furnaces, well pumps, ranges and water heaters.

A refrigerator running on its own could last up to almost four days, while a window air conditioner could operate for more than a day.

Of course, real world results will depend on the exact appliances being used, their power consumption and how often they cycle on and off; a modern appliance is much more energy efficient than an old one.

The battery uses 314Ah lithium iron phosphate cells, a chemistry commonly found in larger portable power stations because of its longevity and thermal stability.

Anker rates the cells for up to 10,000 charge cycles and estimates a service life of as much as 15 years under specified conditions.

There’s an uninterruptible power supply function, too, with a claimed 10-millisecond switchover when grid power fails. That should help keep your equipment running during a sudden outage, which is obviously useful for things like freezers and heating units.

Using a 4,500W, 240V charging source, the battery can go from empty to full in as little as 99 minutes. Solar input reaches 3,000W, and the unit can accept power from a generator as well.

You can add expansion batteries to increase storage from 5kWh to 30kWh too.

At 97lb, the S5000 is still a hefty piece of kit, but Anker has a size advantage over many of its rivals in this category. The Jackery Explorer 5000 Plus stores a similar 5,040Wh of energy but weighs 134.5lb and occupies around 105 liters, and BLUETTI’s 5,100Wh EP500 Pro is heavier still at 182lb, although its lower output and different design make it a less direct comparison.

It’s been a busy couple of months for Anker. Last month, at IFA 2026 in Berlin, the company announced that it was bringing its established product brands together under the Anker name, including established brands like Eufy, Soundcore and SOLIX.

It also revealed the Anker for Home category, which is particularly interesting for the smart-home market. Alongside a bunch of new energy products, Anker used IFA to show off MindBase , a local AI home hub designed to connect devices, process decisions and store household data locally.

MindBase is part of a bigger push towards a more connected home, with security cameras, robotics and energy storage all wrapped up into an AI-assisted control center.

So while the S5000 is a substantial new product in the SOLIX range, it also fits the company’s wider ambition to bring charging, home energy and smart-home technology together.

The S5000 goes on sale in the US on October 27 through Anker’s online store and Amazon, priced at $2,499.99 during its launch promotion, against a regular price of $3,599.99.

If you register for early access between October 9 and October 26 and purchase the unit by November 9 you will also receive a promotional package valued at $699, including a two-year warranty extension, an Anker Prime Charging Station and a generator charging cable.
