Anker SOLIX F2000 Review: Home Backup Power Analyzed

The short answer: the Anker SOLIX F2000 is a solid 2,048Wh home-backup station with 2,400W of output and 1,000W of solar input, and an independent lab got 1,870Wh out of it. But it weighs 67 lb, and Anker's newer C2000 Gen 2 offers the same 2,048Wh and 2,400W at 41.7 lb, with a 5-year warranty and 4,000 rated cycles, for $999.99. Buy the F2000 only at a clear discount or if you specifically need its higher solar input. Anker's Canadian store lists the F2000 as sold out.

By the Numbers

Specs are cross-checked against Anker's SOLIX F2000 page and C2000 Gen 2 page (October 3, 2026). Test figures come from StorageReview's December 2023 review, an independent test we did not run ourselves.

StorageReview needed about 2,300Wh from the wall to fill the F2000, so budget for around 20% charging loss.

What Works

• High measured usable capacity: 1,870Wh, or 91% of rated, is excellent in the class.
• 1,000W solar input, 200W more than the C2000 Gen 2, for faster solar refills.
• 2,400W output runs a window AC, a microwave, or power tools.
• Large expansion path: Anker's page lists expansion to 4,096Wh.

What Doesn't

• Heavy: at 67.2 lb it stays where you put it, about 25 lb heavier than its successor.
• Superseded: the C2000 Gen 2 has the same capacity and output, more cycles, and less weight.
• Availability and price are unclear, with Anker Canada showing it sold out. Check current stock and price.
• Earlier version of this page said it expands to 4,608Wh with a BP2600; Anker's own page lists 4,096Wh, so we corrected it.

How It Compares

What This Actually Runs

Based on the measured 1,870Wh:

• Full-size refrigerator (150W average): about 12.5 hours
• Full-size refrigerator (250W peak-average): about 7.5 hours
• Mini fridge (80W): about 23 hours
• Space heater (1,200W): about 1.6 hours
• CPAP, 40W without humidifier, 8-hour nights: about 5.8 nights (about 2.9 with a heated humidifier)

Earlier versions listed 45+ CPAP nights; that treated hours as nights. Use our wattage sizing guide and CPAP guide.

Who Should Buy This

Someone who finds a deeply discounted F2000 and does not need to move it, or who needs up to 1,000W of solar input. Most shoppers should look at the C2000 Gen 2 first, or the EcoFlow Delta 2 Max, Bluetti Elite 200 V2, or Bluetti AC200L. For repeated storm outages, see our hurricane preparedness checklist.

How much usable energy does the F2000 deliver?

StorageReview measured 1,870Wh delivered, about 91% of the 2,048Wh rating, and about 2,300Wh drawn from the wall to recharge it.

Can the F2000 be expanded?

Yes. Anker's product page lists expansion to 4,096Wh with a compatible battery. Check the exact accessory model with Anker before buying.
