The end of summer doesn’t mean you’re in the clear when it comes to severe weather. Fall and winter can bring strong storms and power outages that could last for days. But you can keep your essential appliances running and your devices charged with a battery backup system like the Anker Solix S2000. And right now at Amazon, you can save almost 50%, bringing the price down to $650.
Anker Solix S2000 for $650 (save $550)
This battery backup packs a ton of power into an incredibly compact form. With a peak output of 3,000 watts and a running output of just over 2,000W, you’ll be able to charge devices, keep your fridge running, or power essential medical equipment for up to 35 hours. The Solix S2000 features 8 different outlets so you can connect multiple appliances and devices at once, including 120V outlets and USB ports. We’ve tested multiple Anker power stations over the years, and trust the company’s products.

The Solix S2000 is rated for up to a 15-year lifespan and 10,000 charging cycles, which means you won’t have to worry about being without emergency power if you forgot about the generator in your garage or garden shed. The companion app lets you monitor power output and remaining charge time, and set up time-sensitive auto-charging modes as severe weather rolls in to keep your essential devices powered on.
For complete off-grid power, you can pair the Solix S2000 with a solar panel for continuous charging and longer-lasting energy during extended blackouts. And you can connect multiple units together for expandable solutions if you need more energy to run your home, but don’t want to spend a fortune on a bulky gas generator. The compact form and zero-emission design means that you can safely run the battery backup inside your home without worrying about dangerous carbon monoxide buildup.
