Anker launches 5kWh backup power station with 48-hour runtime

Anker introduced the SOLIX S5000 on Oct. 9, a 5,024Wh portable power station designed to keep home essentials running for up to 48 hours during outages. The model adds 4,500W dual-voltage output, expandable storage and TÜV SÜD's top runtime rating, with sales set to begin Oct. 27.

Why it matters: - The Anker SOLIX S5000 is built to serve as a home backup source during outages, with enough capacity to keep essential devices running for up to 48 hours. - The unit targets buyers who need portable power for both everyday outages and larger household loads, including 120V and 240V appliances. - Anker is positioning the S5000 in the crowded 5kWh class by emphasizing runtime, safety, size and recharge speed.

What happened: - Anker introduced the SOLIX S5000 on Oct. 9 in Bellevue, Washington. - The portable power station has 5,024Wh of capacity and is backed by Anker SOLIX Brand Ambassador Troy Aikman. - The S5000 will go on sale Oct. 27 at AnkerSOLIX.com and Amazon. - Launch pricing is $2,499.99, below the $3,599.99 MSRP.

The details: - Anker says OptiSave 2.0 Technology delivers up to 96% efficiency under a 1,000W light load. - The system lowers idle power use to 8.8W in 120V mode. - Anker says that improves runtime by 20% and supports up to 21 days of standby. - In Anker SOLIX testing, the S5000 powered a refrigerator, Wi-Fi router, coffee maker, lights and a mobile phone for 48 hours. - Tested on its own, the S5000 powered a refrigerator for up to 86 hours and a window air conditioner for up to 25 hours. - TÜV SÜD gave the S5000 an A+ Runtime rating, which Anker says is the first 5kWh portable power station to receive that grade. - The A+ rating reflects usable output energy, conversion efficiency, energy retention and energy density by volume. - The battery uses 314Ah lithium iron phosphate cells rated for up to 10,000 cycles. - Anker gives the S5000 an estimated service life of up to 15 years under specified conditions and backs it with a five-year warranty. - The unit is UL 9540 certified and tested in accordance with UL 9540A. - The 5kWh base system can expand to 30kWh with additional batteries. - The S5000 delivers 4,500W of rated output and up to 8,000W of peak output. - Its 120V and 240V connections can power essentials and compatible furnaces, well pumps, ranges and water heaters. - The 240V output remains available while the S5000 charges from a 120V source. - A 10-millisecond UPS switchover helps keep compatible devices running during outages. - The S5000 operates at less than 30 dB under specified conditions. - At 97 pounds and 58 liters, the S5000 is 28% lighter and 45% smaller by volume than selected competing 5kWh-class models. - Wheels and a telescoping handle are built in for easier movement and storage. - The unit can recharge from zero to 100% in as little as 99 minutes with a 4,500W, 240V charging source. - The S5000 accepts up to 3,000W of solar input. - Customers who sign up at AnkerSOLIX.com from Oct. 9 through Oct. 26 and buy the S5000 from Oct. 27 through Nov. 9 receive a bonus package valued at $699. - The bonus package includes a two-year warranty extension, an Anker Prime Charging Station and an Anker SOLIX Smart Generator DC Charging Cable. - Product images, specifications and additional information are available in the ANKER SOLIX S5000 PRESS KIT.

Between the lines: - Anker is using runtime claims, safety certifications and compact dimensions to differentiate the S5000 from other portable power stations in the same capacity range. - The A+ runtime rating and UL certifications are likely aimed at buyers who care about real-world backup performance and battery safety. - The dual-voltage output and expandable storage broaden the product beyond basic outage backup into more demanding home and hybrid-use cases. - The launch also leans on incentives, including a limited-time bonus package, to drive early purchases.

What's next: - Sales begin Oct. 27 through AnkerSOLIX.com and Amazon. - The sign-up offer runs from Oct. 9 through Oct. 26, with the purchase window for the bonus package running from Oct. 27 through Nov. 9. - Buyers who want longer backup time can add batteries to expand capacity to 30kWh. - Anker says the S5000 is part of Anker SOLIX's broader push into home energy storage and portable backup power.

The bottom line: - The SOLIX S5000 is Anker's pitch for a more compact, higher-runtime 5kWh backup station that can handle both standard household loads and heavier 240V appliances.
