Quick verdict
The Anker SOLIX S2000 is a 2,010Wh portable power station built around home backup: 1,500W of output (3,000W peak), a sub-10ms UPS switchover at a whisper-quiet 30dB, and 314Ah LFP cells rated for 10,000 cycles, roughly 15 years of regular use. At £649 on Amazon with the current voucher (list £1,099) it is strong value for a 2kWh unit, and at 16.2kg it is Anker's smallest and lightest. Buy it for home and office backup, or as a do-most portable station. Two catches: there is no 12V DC car port, and unlike the C2000 Gen 2 it is not expandable, so if you need 12V output or room to grow, look there instead.

Should you buy the Anker SOLIX S2000?
The S2000 is Anker's newest 2kWh portable station, and it is aimed squarely at keeping a home or a home office running when the power drops. It pairs 2,010Wh of capacity with 1,500W of continuous output (3,000W peak), and its two headline tricks are a sub-10ms UPS switchover, so a desktop or a router never notices the cut, and a battery Anker rates at 10,000 cycles, around a 15-year lifespan. It does all that in the smallest, lightest 2kWh body on the market: 16.2kg and 20.8 by 28.2 by 32.3cm, which Anker claims is 30 percent smaller and 25 percent lighter than the class average.
The whole buying decision, though, comes down to price. On Amazon the S2000 carries a list price of £1,099, and at that number it is unremarkable next to a £999 Bluetti Elite 200 V2 or the EcoFlow Delta 3 Max. But Amazon is currently running a voucher that brings it to £649, matching the deal Anker is pushing on its own site, and at £649 it is one of the best-value 2kWh units you can buy, undercutting the expandable Anker C2000 Gen 2 by £350. Buy it while that voucher holds and it is an easy recommendation for home backup and general use. Pay full price and it is ordinary.
Two honest limits before you commit: the S2000 has no 12V DC car socket (all seven outlets are AC and USB, front and rear), so it is less suited to running a 12V cool box directly than a campsite-focused unit. And it is not expandable, with no add-on battery in the range, so what you buy is your ceiling.

SOLIX S2000, from £649
Anker's newest 2kWh unit, built for home backup: 2,010Wh, 1,500W (3,000W peak), a sub-10ms UPS at a quiet 30dB, and a 314Ah LFP battery rated at 10,000 cycles, around 15 years, in the smallest and lightest 2kWh body at 16.2kg. £649 on Amazon with the current voucher (list £1,099), which undercuts the expandable C2000 Gen 2 by £350. No 12V DC port and no expansion battery, so it trades flexibility for value and longevity.

Nine configurations, but they fall into two groups. The first five are the same unit with a different accessory: the £649 base comes with the AC charging cable, then there are versions bundling a car charging cable (£669), a waterproof bag (£693), or a car charger (£928 to £958). The other four bundle a solar panel at 100W (£753), 200W (£863) or 400W (£1,048), which matters because the S2000 accepts up to 400W of solar and Anker quotes a 20 to 80 percent solar recharge in three to four hours at that wattage. Prices shown are the current Amazon voucher prices, which move; the list prices are roughly £450 to £850 higher.
What can 2,010Wh actually run?
With 1,500W of continuous output (2,300W in bypass, 3,000W peak surge), the S2000 runs nearly every home essential: a fridge-freezer, wifi and router, a laptop and monitors, lighting, a CPAP machine overnight, and short bursts from higher-draw kit like a microwave or a kettle within the peak. Anker quotes up to 24 hours of "family backup" from a 2kWh charge, helped by a low 10W idle draw that wastes less between uses than most rivals.
Where it is not the tool: the missing 12V DC port means you cannot run a 12V camping fridge or car accessory directly, and 1,500W is below the 1,800W to 2,400W of some 2kWh rivals, so a big power tool or a 2,000W-plus heater is out. For a house, an office and general portable power it has the output that matters; for a workshop or a 12V-heavy campsite setup, check the numbers first.

Within Anker's own range the choice is clean. The C2000 Gen 2 (£999) is the one to buy if you want your 2kWh to double later, because it takes an expansion battery and the S2000 does not. The S2000 is the one to buy for home backup on a budget: cheaper on the voucher, quieter, a longer-life 10,000-cycle battery, and the smallest and lightest body. If you carry USB-C kit rather than back up a house, the tiny £189 C300 DC is a different animal entirely.
Against other brands at 2kWh, the S2000's case is the voucher price and the cycle life. A Bluetti Elite 200 V2 or an EcoFlow Delta 3 Max gives you more raw output and, in some trims, expandability, but neither matches a £649 entry or a 15-year battery rating.
