Our verdict · Anker SOLIX

4.6/104.6/10How we rate

A light 2 kWh station with a low idle draw, but modest output and no expansion

The S2000 packs 2 kWh into a 35.7 lb station and draws only 6 W at idle, so more of its battery reaches your devices. Its 1,500 W output, 400 W solar input and lack of expansion keep it to essentials.

Best for

Long, low-power backup such as a fridge, router, lights and CPAP, where weight and idle draw matter more than output.

Skip it if

You need more than 1,500 W, strong solar input or room to add batteries.

Key specs at a glance

What the numbers mean in practice

  • 2,010 Wh capacity: about a day of a fridge and router.
  • 1,500 W continuous, 3,000 W peak: a fridge, lights, a TV and small appliances, not a space heater with other loads.
  • LiFePO4, 10,000 cycles to 60%: Anker quotes cycles to 60%, while most makers quote 70–80%, so the numbers aren't directly comparable. See LiFePO4 vs lithium-ion.
  • 35.7 lb: light for 2 kWh.
  • 6 W idle draw: less of the battery is lost just keeping the inverter on.
  • Not expandable; 5-year warranty.

Spec sheets are easy to misread; watts vs watt-hours explains which number answers which question.

Charging speed

About 2.3 hours from the wall

By default it charges at 1,150 W, full in about 2.3 hours. Turning on UltraFast in the app raises that to 1,600 W.

The Anker SOLIX S2000 charging from a folding solar panel on a patio
About 2.3 hours from the wall; up to 400 W of solar.

Solar input tops out at 400 W, low for a 2 kWh station, so a full solar charge takes a long sunny day or more. See solar panel sizing.

Capacity and real runtime

About a day of essentials

Estimated runtimes on the S2000

  • CPAP, no humidifier, DC cord2.2 days
  • CPAP with humidifier, AC23 h
  • Fridge + Wi-Fi router22 h
2,010 Wh at 85% efficiency for AC and 92% for DC, plus Anker's stated 6 W idle draw when AC is on. CPAP 35 W / 70 W; fridge 60 W average; router 12 W.

About a day of fridge and router power.

A fridge and router run for about a day. See how long a power station runs a refrigerator, or try the runtime calculator.

Output: what it can and can't run

1,500 W continuous

It has AC outlets on the front and back. Its 1,500 W covers a fridge, freezer, lights, a TV, a router and small appliances. When it's plugged into the wall, bypass can pass up to 1,800 W.

It won't run a space heater, a large microwave or several kitchen appliances at once.

Backup (UPS) and app

10 ms or less

Plugged into the wall, it switches to battery in 10 ms or less, fast enough for most computers and routers. See using a power station as a UPS.

Who should buy it

And who should look elsewhere

Good fit: anyone who wants a day of essentials in the lightest 2 kWh package, with a low idle draw and a fast backup switchover.

Look elsewhere if: you need more output, strong solar charging or expansion. The HomePower 2000 Plus v2 or Elite 200 V2 suit that better. See the best portable power stations for home backup.
