If you want home backup power without a bulky, heavy unit taking up a corner of the garage, this is a genuinely good price for it. Right now, the Anker Solix S2000 is $600 (was $1199) at Amazon — a massive 50% off on a 2kWh power station built specifically for keeping essentials running through an outage.
The headline feature here is the size-to-capacity ratio. At 35.7lbs and roughly the footprint of a large kitchen bin, the S2000 packs in 2,010Wh of LiFePO4 capacity in a chassis around 30% smaller and 25% lighter than typical 2kWh power stations. That matters if you're planning to keep this somewhere specific in the house rather than store it in a garage.

Anker's OptiSave system is the other notable piece of engineering. It drops the unit's active idle power draw down to around 6W with the AC outlets enabled, and roughly 2W with everything switched off — well below the 14-20W idle draw typical of competing 2kWh stations. Since a backup power station mostly sits idle waiting for an outage, or cycles a fridge compressor on and off, that lower standby drain translates into meaningfully more real-world runtime rather than just a better spec sheet number.
Port placement is a small but genuinely useful design choice: two AC outlets sit on the back for always-on gear like a fridge or router, while three more AC outlets plus USB-C and USB-A ports sit on the front for everyday devices. That split keeps cables from getting tangled if you're running multiple things at once, and the 10ms UPS switchover means a connected computer or router won't even blink when the grid drops.
The 10,000-cycle LiFePO4 battery is rated for roughly 15 years of typical use, which is close to double the cycle rating most mainstream power stations in this capacity class advertise — a genuine long-term value argument if you're planning to keep this around rather than replace it after a few years.
Important notes: the S2000 caps out at 1,500W continuous output, so it's not the right choice if you need to run power tools, space heaters, or other high-draw appliances — Anker's own larger Solix units handle that heavier lifting. Solar input is also capped at 400W, lower than some rivals that accept 600-1,000W, so it's better suited to topping up with a single panel than building out a larger solar array. And with only two USB-C ports and one USB-A port, it's clearly built around AC backup duty first, device charging second.
For anyone who wants dependable home backup without the bulk of a typical 2kWh unit, the SOLIX S2000 at $599.99 is a strong buy.
