The Anker SOLIX S2000 Portable Power Station keeps your refrigerator, router, and CPAP machine powered through a grid outage. Plug your appliances into the five AC outlets on the case, and the S2000 delivers wall-speed power until the battery empties or your grid comes back. Storm Guard connects to the National Weather Service through the Anker app and automatically charges the battery ahead of hurricanes, ice storms, and other forecast events in your area. Plus, at 35.7 pounds, one person can carry it between rooms.
The perfect companion for anyone who needs an extra power boost anywhere they go
A standard fridge draws about 150 to 200 watts under compressor load and around 40 watts the rest of the time, and Anker rates the S2000’s 2,010-watt-hour battery at 35 hours of coverage based on those numbers. That’s a day and a half of grid downtime before you have to worry about anything in the fridge starting to warm up.
The cells inside are LiFePO4, which is a step down in energy density from the lithium-ion cells you’d find in a laptop, but a long step up in lifespan. Tesla runs LiFePO4 in the base Powerwall. Ford runs it in the standard-range F-150 Lightning. Anker uses next-generation 314 Ah cells in the S2000, the same size used in utility-scale battery installations. That’s a larger cell than most portable power stations use, and it’s why the S2000 hits a 10,000-cycle rating instead of the 3,000 to 4,000 cycles typical for this capacity.
Wall power, solar, or a car alternator will all recharge the battery, and the input controller accepts multiple inputs at once if you want to combine them. Wall charging at 1,150 watts brings the S2000 from dead to full in around two and a half hours. UltraFast mode pushes the input to 1,600 watts and cuts the time further, though the tradeoff is some long-term cycle life. Solar tops out at 400 watts through the DC port.
Storm Guard is the setting worth turning on in the Anker SOLIX app. Left running in the background, it monitors NWS weather alerts and automatically tops off the S2000 ahead of anything likely to take down the grid. So when the actual storm hits, the battery’s already at 100% instead of wherever it happened to be sitting when the forecast came in.
Losing power for a day and a half is the exact situation the S2000 is built for. You plug the refrigerator, the router, and whatever else you actually need into the outlets on the case, and the battery keeps them going long enough that you don’t have to throw out a week of groceries or camp out at a coffee shop to answer emails. At $600, down from $1,200, the current sale takes half off the retail price on a battery Anker designed to last 15 years.
