$1,600 buys 240V and a hookup to the house, not just a bigger battery.

The Anker SOLIX C2000 Gen 2 stores 2,048Wh and delivers 2,400W at 120V, with a TT-30 RV outlet, 800W of solar, a 10ms UPS and one extra battery for 4,096Wh, at 41.7 lb. 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 with six batteries, at 135.6 lb on wheels. For a well pump, central air or a whole circuit panel, only the F3800 Plus does it; for a fridge, a desk and a weekend in the RV, the C2000 Gen 2 does it for far less.

Below: every difference with numbers, a 20-second calculator for your own gear, seven modeled situations, a third option, and what published tests found on each.

Quick answer

Prices $1,600 apart today. The F3800 Plus brings 1,792Wh more, 6,000W at 120V and 240V, 3,200W of solar, home panel and generator connections and six-battery expansion. The C2000 Gen 2 is 94 lb lighter, switches in 10ms instead of 20ms and covers most 120V outages for a fraction of the price.

Bottom line: these aren’t two sizes of the same thing. The C2000 Gen 2 is a portable 120V station: 2,048Wh, 2,400W, a 10ms UPS and 41.7 lb, with one extra battery for 4,096Wh. The F3800 Plus is a home system on wheels: 3,840Wh, 6,000W at 240V, 3,200W of solar, a Home Power Panel or transfer switch hookup and up to 26.9kWh. If nothing in your plan runs on 240V, the C2000 Gen 2 saves you $1,600; if a well pump or central air is the point, the F3800 Plus is the one, and the F3000 below sits in between.
01 · Differences

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 have a TT-30 outlet and a 12V socket, and Anker gives both 5 years of warranty once registered.

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 C2000 Gen 2 and 3,264Wh on the F3800 Plus, before any extra battery. PCMag measured about 4,248Wh of AC from an F3800 Plus with one expansion battery.

Runtime verdict

Appliance for appliance, the F3800 Plus lasts 88% longer than the C2000 Gen 2.

Same appliance, same watts: the gap is always the size of the battery.

The price gap, in numbers

Price verdict, today

The Anker SOLIX F3800 Plus costs $1,600 more than the Anker SOLIX C2000 Gen 2 and adds 1,792Wh: that is $0.89 per extra Wh, against $0.49 per Wh for the C2000 Gen 2.

With its extra battery, the C2000 Gen 2 stores about as much as an F3800 Plus; the figures above compare both at today’s prices. What that pair can’t do is 240V, 6,000W or a home panel connection. The lifetime figure divides each price by its rated cycles times its capacity; read it as a ranking, not a bill. Anker US prices move often; the figures here are refreshed daily by our price engine.

TakeawayFor 4kWh at 120V, the C2000 Gen 2 and its battery do the job; for 240V, only the F3800 Plus counts.

The third option: the Anker SOLIX F3000 at $1,699.99

Anker SOLIX F3000 portable power station with wheels and pull handle

Anker SOLIX F3000: $1,699.99 today

The middle step: 3,072Wh on wheels, 3,600W through its TT-30R (2,400W on the household outlets), 2,400W of solar, a 20ms UPS and up to three BP3000 batteries for 12,288Wh, at 91.5 lb. It has more battery and power than the C2000 Gen 2 without the F3800 Plus’s 240V outlet. Pick it for an RV or a 120V home setup that can grow. Our F3000 review goes deeper. See the F3000 at Anker.

05 · Situations

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

Fridge + Wi-Fi router + phones and a laptop + 5 LED bulbs: about 2,190Wh a day (the calculator’s Power outage preset)
C2000 Gen 219.1 h
F3800 Plus35.8 h

The F3800 Plus covers a full day and a half; the C2000 Gen 2 about 19 hours, close to a day. PCMag ran a full-size fridge about 63 hours on an F3800 Plus with one expansion battery.

A 240V well pump or central air

A 240V load on the home circuit, through a transfer switch or Anker’s Home Power Panel
C2000 Gen 2120V only
F3800 Plus6,000W at 240V

Only the F3800 Plus: its L14-30R outlet and home panel port deliver 6,000W at 240V. The C2000 Gen 2 is 120V only; a 120V well pump under 2,400W running is fine, a 240V one isn’t.

An RV on a 30A TT-30 inlet

Plugging the RV’s shore power cord straight into the station
C2000 Gen 2TT-30, 2,400W
F3800 PlusTT-30R, 3,000W

Both have a TT-30 outlet. The F3800 Plus allows 3,000W through it and stores nearly twice as much; the C2000 Gen 2 fits in the RV and adds 800W alternator charging, sold separately.

Home office through an outage

Desktop PC + monitor 8 h + router and modem all day: about 1,850Wh a day (the calculator’s Home office UPS preset)
C2000 Gen 2 (10ms)22.6 h
F3800 Plus (20ms)42.3 h

The C2000 Gen 2 switches in 10ms, inside the roughly 16ms a desktop power supply rides through. The F3800 Plus switches in 20ms on its three left outlets, with a 1,440W pass-through limit; PCMag still kept a workstation running through simulated outages.

Refill from solar, each at its maximum

Hours of full sun to refill from empty, at 70% of panel rating: 800W against 3,200W
C2000 Gen 23.7 h
F3800 Plus1.7 h

The F3800 Plus refills nearly twice the battery in under half the time, if you have the panels: 3,200W is eight 400W panels. Its 165V inputs also take panels in series.

Refill from the wall before a storm

From empty, from a standard 120V outlet
C2000 Gen 2 (1,800W)88 min
F3800 Plus (1,800W)about 2.1 h

Same 1,800W input from a 120V outlet, nearly twice the battery to fill. The F3800 Plus also takes 3,300W from a 240V generator, or 6,000W with an expansion battery, through Anker’s Generator Input Adapter. The C2000 Gen 2 reaches 58 minutes with AC and solar together.

Moving it

From the garage to the kitchen, or into a truck bed
C2000 Gen 241.7 lb
F3800 Plus135.6 lb

The C2000 Gen 2 is a one-person carry. The F3800 Plus rolls on wheels with a trolley handle, but Gear Diary weighed 132.3 lb and AppleInsider noted small bumps can stop the wheels: plan on two people for stairs.

Anker rates the C2000 Gen 2 at 4,000 cycles and the F3800 Plus at 3,000+, both to 80% capacity: about 11 and 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.

Before you buy
  • Register either one with Anker when it arrives and keep proof of purchase: Anker’s registration page says that activates the coverage.

What reviewers report

We have not lab-tested these two units. Here is what 9 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.

  • F3800 PlusReviewer Background draw averages about 30 to 40W while operating, which adds up over days. PCMag, Michael Lydick, May 2026
  • F3800 PlusReviewer The original F3800 uses over 1kWh a day idle; the Plus draws slightly less, maybe an extra hour or two. How-To Geek, Bertel King, March 2025
  • F3800 PlusReviewer Weighs 136.7 lb; small bumps can stop the wheels. AppleInsider, Wesley Hilliard, August 2025
TakeawayReviewers praise the C2000 Gen 2’s output, quiet fans and light weight, with weaker efficiency at small loads. Tests of the F3800 Plus confirm long runtimes and a reliable UPS, with a 30 to 40W background draw and its weight as the drawbacks.
14 · Practical limits

Practical limits before you buy

  1. The F3800 Plus is sold out at Anker US as of October 31, 2026. The price engine shows today’s listing; check stock before you plan around a date.
  2. The C2000 Gen 2 is 120V only. A 240V well pump, dryer or central air needs the F3800 Plus.
  3. 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.
  4. No surge figure for the F3800 Plus. The 9,000W often quoted belongs to the original F3800.
  5. The F3800 Plus has a background draw. PCMag measured about 30 to 40W while operating, which adds up over days; the C2000 Gen 2 idles at 9W, per Anker.
  6. 135.6 lb. The F3800 Plus rolls, but stairs and truck beds are a two-person job.
  7. Solar cables: two are in the F3800 Plus box; the C2000 Gen 2’s PV to XT60i cable is sold separately.
  8. C2000 Gen 2, per its US documentation: When the 15W USB-C and 12W USB-A ports are used together, total output is limited to 20W.
  9. C2000 Gen 2, per its US documentation: USB-C ports are output only; they cannot charge the unit.
  10. C2000 Gen 2, per its US documentation: Only 9W idle consumption; fridge runtime of 32 hours is based on Anker internal testing.
  11. C2000 Gen 2, per its US documentation: Charging temperature 32 to 104F (0 to 40C); discharging -4 to 104F.
  12. F3800 Plus, per its US documentation: The 240V output cannot be used while the unit charges from 120V AC.
