An F2000 still runs a 120V outage; the F3800 Plus runs the house.
The Anker SOLIX F2000 stores 2,048Wh and delivers 2,400W at 120V from four NEMA 5-20 outlets and a TT-30, with 1,000W of solar, a light bar and one extra battery for 4,096Wh, at 67.2 lb on wheels. Anker US no longer sells it: its page now redirects to the C2000 Gen 2. The Anker SOLIX F3800 Plus stores 3,840Wh and delivers 6,000W at 120V and 240V, takes 3,200W of solar, connects to Anker’s Home Power Panel or a transfer switch and grows to 26.9kWh, at 135.6 lb. If you own an F2000 and your loads are 120V, keep it; move up only for 240V, a panel hookup or much more storage.
Below: every difference with numbers, a 20-second calculator for your own gear, seven modeled situations, the F2000’s replacement, and what published tests found on each.
Anker US no longer sells the F2000, and the F3800 Plus was sold out at Anker US on October 31, 2026. The F3800 Plus brings 1,792Wh more, 6,000W at 120V and 240V, 3,200W of solar and a home panel connection. The F2000 is half the weight, with two 12V sockets and a light bar, and does 120V outages fine.
- your loads are 120V, under 2,400W
- you move it: 67.2 lb
- you use two 12V sockets
- you need 240V, 6,000W
- you wire it to the house
- you want up to 26.9kWh
The five differences that decide it
The gaps that change what you can run or how long, with the better spec flagged. Both use LFP, both roll on wheels, both have a TT-30 outlet, and Anker lists both at 5 years of warranty (the F3800 Plus once registered).
Will it run your setup? Check in 20 seconds
Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes. About 1,741Wh usable on the F2000 and 3,264Wh on the F3800 Plus, before any extra battery. StorageReview got 1,870Wh out of an F2000; PCMag measured about 4,248Wh of AC from an F3800 Plus with one expansion battery.
Appliance for appliance, the F3800 Plus lasts 88% longer than the F2000.

What the current options cost today
The C2000 Gen 2 is where Anker US now sends F2000 shoppers: the same 2,048Wh and 2,400W, five NEMA 5-20 outlets and a TT-30, 800W of solar and one expansion battery, with a 10ms UPS, at 41.7 lb. The F3800 Plus does more: 240V, 6,000W and a home panel. The lifetime figure divides each price by its rated cycles times its capacity; read it as a ranking, not a bill.
The third option: the Anker SOLIX C2000 Gen 2 at $999.99
Anker SOLIX C2000 Gen 2: $999.99 today
Where Anker US now sends F2000 shoppers: the same 2,048Wh and 2,400W, five NEMA 5-20 outlets and a TT-30, a 12V socket, 800W of solar, a 10ms UPS and one BP2000 Gen 2 for 4,096Wh, at 41.7 lb, 25.5 lb lighter than the F2000. It drops the F2000’s wheels and light bar, and like the F2000 it is 120V only. Our C2000 Gen 2 vs F2000 comparison goes deeper. See the C2000 Gen 2 at Anker.
Seven modeled situations, worked out
Same formula as the calculator above: 85% of the rated capacity, no extra battery. The fridge averages 60W.
24-hour outage, essentials only
The F3800 Plus covers a day and a half; the F2000 about 19 hours. Gizmodo kept a full-size basement fridge running for about 34 hours on an F2000.
A 240V well pump or central air
Only the F3800 Plus: its L14-30R outlet and home panel port deliver 6,000W at 240V. The F2000 is 120V only, and The Technology Man found it struggled to start most induction-motor machines, despite ratings under its limit.
An RV on a 30A TT-30 inlet
Both have a TT-30 outlet. The F2000 shares its 2,400W with the household outlets; the F3800 Plus allows 3,000W through its TT-30R and stores nearly twice as much.
Home office through an outage
Similar switchover on paper: under 20ms on the F2000, 20ms on the F3800 Plus’s three leftmost outlets. Trusted Reviews kept office equipment running through it on an F2000; PCMag kept a workstation running on an F3800 Plus.
Refill from solar, each at its maximum
The F3800 Plus refills nearly twice the battery faster, if you have eight 400W panels. The F2000 can’t take AC and solar at the same time; AC input takes priority.
Refill from the wall before a storm
Android Central measured 112 minutes on an F2000 at its 1,440W maximum. The F3800 Plus takes 1,800W from a 120V outlet, and 3,300W from a 240V generator through Anker’s Generator Input Adapter, 6,000W with an expansion battery.
Moving it
Both roll on wheels. The F2000 is a two-person lift into a vehicle; the F3800 Plus doubles that, and AppleInsider noted small bumps can stop its wheels.
Nine more differences, the spec sheet and the box
Smaller gaps that rarely decide the purchase, then the full specifications and what ships in the box.
F2000 and F3800 Plus weight, dimensions and full specifications
Weight: 67.2 lb for the Anker SOLIX F2000 and 135.6 lb for the F3800 Plus, per its user guide (136.7 lb in the US page’s tech specs). Dimensions: 20.7 × 15.5 × 9.8 in and 27.6 × 15.3 × 15.6 in, wheels included. F2000 figures come from Anker US’s last archived product page (July 25, 2026).

07 · ChargingHow fast each one refills
Shorter bar, faster refill. Each row is scaled to its slower unit.
F2000: Android Central reached 29% in 30 minutes, 77% in 60 and 100% in 112 at the 1,440W maximumF3800 Plus: PCMag measured roughly 9,000Wh from the wall to refill the unit with an expansion battery, about 85% round-trip efficiency
Our solar times assume panels deliver 70% of their rating; the brands’ figures assume ideal sun.
Every port, side by side
F2000
F3800 Plus
Practical consequence: the F2000 has four NEMA 5-20 outlets and a TT-30 at 120V, three USB-C, two USB-A and two 12V sockets. The F3800 Plus has six NEMA 5-20R outlets, a TT-30R at 120V and an L14-30R at 120/240V, USB-A and USB-C, one 12V socket, and a Home Power Panel and generator port.
09 · NoiseNoise: F2000 vs F3800 Plus
Anker publishes no rating for either. The Anker SOLIX F2000 measured 49 to 55dB while fast charging and about 60dB at full output (UK and EU units); AppleInsider measured up to 60dB from the Anker SOLIX F3800 Plus under a heavy load.
Both are quiet at light loads and loud near full power.Every figure we found, with its source
What reviewers heard: Almost silent at low output, with the fan noticeable from about 1,000W (Notebookcheck).
What reviewers heard: Whisper-quiet until heavily loaded; then the fans may reach 60 decibels (AppleInsider).
Measured by a tester Brand figure
- Use the F2000’s silent charging mode overnight; put the F3800 Plus in a garage or utility room.
Cold and heat: F2000 vs F3800 Plus
Same ranges on the Anker SOLIX F2000 and the Anker SOLIX F3800 Plus: charging from 32°F to 104°F, running from −4°F to 104°F, per Anker.
Figures from Anker’s archived F2000 page and the F3800 Plus user guide.- In a garage in winter, keep either one where it stays above 32°F while charging: neither charges below freezing.
App, UPS and smart features
The Anker SOLIX F3800 Plus is the one that wires into the house, charges from a 240V generator and grows to 26.9kWh. The Anker SOLIX F2000 switches in under 20ms and takes one extra battery.
Both run from the Anker app over Wi-Fi or Bluetooth.Green zone: a switch under about 16ms, which most desktop PCs ride through without restarting.
Does it connect to a home panel? The Anker SOLIX F3800 Plus connects to Anker’s Home Power Panel, a transfer switch or an inlet box.
Can it charge off-peak? Trusted Reviews found the F2000’s app can set timers but not schedule off-peak overnight charging; Anker ties the F3800 Plus’s bill savings to its Home Power Panel.
Can it charge from a 240V generator? The Anker SOLIX F3800 Plus takes a 240V generator through Anker’s Generator Input Adapter, sold separately, single unit only.
Can you add a battery later? The Anker SOLIX F2000 takes one BP2000; the Anker SOLIX F3800 Plus takes up to six BP3800, and 53.8kWh with two units.
Does it work as a UPS? Notebookcheck found the Anker SOLIX F2000’s switchover reliable; the Anker SOLIX F3800 Plus switches in 20ms on its three leftmost outlets, with 1,440W of pass-through on a 120V wall outlet.
How does the app connect? Both use the Anker app over Wi-Fi or Bluetooth.
Warranty and support
Anker lists 5 years for the Anker SOLIX F2000, and 5 years for the Anker SOLIX F3800 Plus once it’s registered with Anker. The F2000 is no longer sold by Anker US; an existing unit keeps the term it was sold with.
Same term on paper. Check what’s left on a used F2000.Subject to each brand’s warranty terms and eligibility.
Anker rates the F2000 at 3,000 cycles to 80% and the F3800 Plus at 3,000+ to 80%: about 8 years at one full cycle a day. A home backup unit rarely cycles daily, and calendar aging and heat also reduce capacity, so read the ratings as a ceiling.
- If you find an F2000 from another seller, check what’s left of its warranty before buying: Anker US no longer sells it.
- Register a new F3800 Plus with Anker when it arrives: Anker’s registration page says that activates the coverage.
What reviewers report
We have not lab-tested these two units. Here is what 10 published reviews found, with the source, author and date for each point. Reviews of UK and EU units are flagged: those models charge from 230V outlets and have different sockets, so their charge times and outlet findings don’t carry over to US units.

Practical limits before you buy
- Anker US no longer sells the F2000. Its page redirects to the C2000 Gen 2; check any seller’s warranty before buying one.
- The F3800 Plus is sold out at Anker US as of October 31, 2026; check stock before you plan around a date.
- The F2000 is 120V only. A 240V well pump, dryer or central air needs the F3800 Plus.
- 240V generator charging on the F3800 Plus needs Anker’s Generator Input Adapter, sold separately, single unit only; 6,000W needs an expansion battery, 3,300W otherwise.
- No surge figure for the F3800 Plus. The 9,000W often quoted belongs to the original F3800.
- Standby drain on both. Android Central saw an F2000 lose 19% in 12 hours idle with power saving off; PCMag measured about 30 to 40W of background draw on an F3800 Plus.
- Heavy, both of them. 67.2 lb and 135.6 lb: wheels help on flat floors, two people for stairs or a truck bed.
- F2000, per Anker’s archived US page: AC and DC (solar or car) input cannot be used at the same time; AC input takes priority.
- F2000, per Anker’s archived US page: Solar input 11 to 60V via XT-60: 10A max at 11 to 32V, 20A max at 32 to 60V, 1,000W max.

- F3800 Plus, per its US documentation: The 240V output cannot be used while the unit charges from 120V AC.
Frequently asked questions
Is the F3800 Plus the replacement for the F2000?
No. Anker US redirects its F2000 page to the C2000 Gen 2, which keeps the 2,048Wh, the 2,400W, the TT-30 and an expansion port. The F3800 Plus is a bigger tier: 3,840Wh, 6,000W at 120V and 240V and a home panel connection.
Is the F2000 still sold?
Not by Anker US: ankersolix.com/products/f2000 redirects to the C2000 Gen 2. Leftover or used units may exist; check the remaining warranty.
Should I replace my F2000 with an F3800 Plus?
Only if you need 240V, a Home Power Panel or transfer switch hookup, more than 2,400W, or much more storage. For 120V outages, an F2000 plus one BP2000 still stores 4,096Wh.
How long will each run a refrigerator?
At a 60W average and 85% usable capacity, about 29 hours on the F2000 and 54 hours on the F3800 Plus, before any extra battery. Gizmodo ran a full-size fridge for about 34 hours on an F2000.
Can the F2000 run a 240V appliance?
No. It delivers 120V only. The F3800 Plus delivers 240V from its L14-30R outlet and its home panel port, up to 6,000W.
Which is better for an RV?
Both have a TT-30 outlet. The F2000 is half the weight and has two 12V sockets; the F3800 Plus stores nearly twice as much and allows 3,000W through its TT-30R.
How much do they weigh?
67.2 lb for the F2000; 135.6 lb for the F3800 Plus per its user guide, 136.7 lb in the US page’s tech specs. Both roll on wheels.
What warranty do they have?
5 years on both, per Anker US (the F2000’s archived page); the F3800 Plus gets its 5 years once registered with Anker. An F2000 bought earlier keeps the term it was sold with.
