A 240V home unit against EcoFlow’s original big portable. Only one is still sold.
Anker US no longer sells the F3800: its page redirects to the F3800 Plus. The F3800 stored 3,840Wh and delivered 6,000W at 120V and 240V at once from one unit, with a NEMA 14-50 and an L14-30, at 132.2 lb. The EcoFlow DELTA Pro stores 3,600Wh and delivers 3,600W at 120V, with a TT-30, an Anderson port and 1,600W of solar at up to 150V, at 99 lb. It needs a second DELTA Pro and the Double Voltage Hub for 240V.
Below: what changed with numbers, a 20-second calculator for your own gear, eight modeled situations, a third option, and what published tests found on each.
If you’re buying today, the DELTA Pro or the F3800 Plus: Anker US no longer sells the F3800. Against it, the DELTA Pro is 33 lb lighter, with a TT-30 and an Anderson port, but has 240Wh less, 2,400W less output and no 240V from a single unit.
- you need 240V from one unit
- you use its NEMA 14-50
- you’ll grow past 10kWh
- you want 3.6kWh at 120V
- you’ll move it: 99 lb
- your RV takes a TT-30
The five differences that decide it
Both store about 3.6 to 3.8kWh of LFP, take expansion batteries, roll on wheels, have a 12V output and work with a home panel. These five gaps decide it.
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 3,264Wh usable on the F3800 and 3,060Wh on the DELTA Pro.
Appliance for appliance, the F3800 lasts 7% longer than the DELTA Pro.

What the current options cost today
The DELTA Pro works at 120V only; the F3800 Plus keeps the F3800’s 6,000W split-phase inverter. The DELTA Pro’s own extra battery was sold out at EcoFlow US on October 30, 2026.
The third option: the F3800 Plus at $2,399.99
Anker SOLIX F3800 Plus: $2,399.99 today
The F3800’s successor at Anker US: the same 3,840Wh and 6,000W at 120V and 240V at once, 3,200W of solar at up to 165V, 240V generator charging, a TT-30 and an L14-30, and up to six BP3800 batteries, at 135.6 lb. Pick it over the DELTA Pro if you need 240V from one unit or more than 3,600W. Our F3800 vs F3800 Plus comparison goes deeper. See the F3800 Plus at Anker.
Eight modeled situations, worked out
Same formula as the calculator above. Both carry 3,840Wh, so runtimes are identical; the differences show up when you recharge or plug in something special.
24-hour outage, essentials only
Both cover a day and a half; the F3800 runs about 2 hours longer.
A 240V well pump or dryer
The F3800 delivers 240V from one unit. The DELTA Pro needs a second DELTA Pro and EcoFlow’s Double Voltage Hub.
Microwave, coffee maker and space heater
The F3800 has room to spare; the DELTA Pro is right at its 3,600W rating, with no headroom for anything else.
Recharging from a 240V outlet
The DELTA Pro takes 3,000W from a 240V outlet; the F3800 1,800W from a 120V outlet only.
Refill from solar, each at its maximum
The F3800 takes more panels; the DELTA Pro takes higher-voltage strings, up to 150V against 60V.
An RV with a 30A inlet
The DELTA Pro’s TT-30 takes a 30A RV cord directly; the F3800’s 14-50 suits a 50A cord.
Home office through an outage
Both carry two workdays. The F3800’s UPS covers three outlets at 20ms (13ms measured); the DELTA Pro’s EPS is under 30ms, borderline for desktop PCs.
Moving it
Both roll on wheels; the DELTA Pro is 33 lb lighter, but lifting either is a two-person job.
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.

Practical consequence: the F3800 has 240V outlets and six 20A household outlets; the DELTA Pro a TT-30, an Anderson port, DC barrels and more USB.
09 · NoiseNoise: F3800 vs DELTA Pro
The Anker SOLIX F3800 is the quieter one: Notebookcheck measured about 42dB at 1 m during a long 3,000W draw. EcoFlow’s own FAQ puts the EcoFlow DELTA Pro at 48 to 60dB at 1 m, depending on load and temperature.
Both are silent or close to it at low loads.Every figure we found, with its source
What reviewers heard: Silent at low load, about 42dB at 1 m drawing 3,000W for a long time (Notebookcheck, EU unit).
What reviewers heard: Fans switched on near 3,000W with a microwave added, and the unit kept running (CleanTechnica); fans ramp up under heavy draw and fast charging, then can stop completely at low loads (StorageReview).
Measured by a tester Brand figure
- Lower the AC charging power in the app overnight.
Cold and heat: F3800 vs DELTA Pro
For a cold garage, the Anker SOLIX F3800 keeps running down to −4°F; for heat, the EcoFlow DELTA Pro is rated to 113°F. Neither charges below freezing, and neither has a water rating.
Figures from the F3800 user guide (A1790) and the EcoFlow US DELTA Pro page.- Charge either one above freezing: neither charges below 32°F.
- In a hot garage or shed, the DELTA Pro has more margin: rated to 113°F, against 104°F for the F3800.
App, UPS and smart features
The Anker SOLIX F3800 does more: 240V on its own, a 20ms UPS, room for six extra batteries and time-of-day modes. The EcoFlow DELTA Pro needs a second unit for 240V and takes two extra batteries.
Both use Wi-Fi and Bluetooth, and both connect to their brand’s home panel.Green zone: a switch under about 16ms, which most desktop PCs ride through without restarting.
Does it deliver 240V on its own? The Anker SOLIX F3800 delivers 240V on its own; the EcoFlow DELTA Pro needs a second DELTA Pro and the Double Voltage Hub.
Can it charge off-peak? The Anker SOLIX F3800 has time-of-day and peak shaving modes in the app; EcoFlow lists no time-of-use mode for the DELTA Pro.
Does it work as a UPS? On the Anker SOLIX F3800, the three left 120V outlets switch in 20ms, 13ms in StorageReview’s test. The EcoFlow DELTA Pro’s EPS is under 30ms, fine for appliances and borderline for desktop PCs.
Can you add a battery later? The Anker SOLIX F3800 takes up to six BP3800 for 26.9kWh; the EcoFlow DELTA Pro takes two extra batteries for 10.8kWh, sold out at EcoFlow US on October 30, 2026.
Does it connect to a home panel? The Anker SOLIX F3800 works with Anker’s Home Power Panel; the EcoFlow DELTA Pro works with the Smart Home Panel 2.
How does the app connect? Both use their brand’s app over Wi-Fi or Bluetooth, with adjustable charging power.
Warranty and support
Anker listed the Anker SOLIX F3800 at 5 years, and an existing unit keeps the term it was sold with. The EcoFlow DELTA Pro needs registration: EcoFlow’s US warranty table lists 2 years, or 5 once registered in the EcoFlow app.
EcoFlow’s product page says 3 years plus 2; its warranty table says 2 plus 3. We use the shorter base.Subject to each brand’s warranty terms and eligibility.
EcoFlow rates the DELTA Pro at 3,500 cycles to 80% capacity, about 10 years at one full cycle a day. Anker rated the F3800 at 3,000+ cycles without an end-of-life capacity, so the two figures don’t line up exactly.
- Register the DELTA Pro in the EcoFlow app the day it arrives: without registration, EcoFlow’s warranty table gives 2 years.
- If you find a leftover or used F3800, check its warranty date before buying: Anker US no longer sells it.
What reviewers report
We have not lab-tested these two units. Here is what 8 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.

- DELTA ProReviewer Over Bluetooth, the app estimated just over an hour of runtime at that heavy load. CleanTechnica, Jennifer Sensiba, August 2022
- DELTA ProReviewer The reviewers relied on the app often for local and remote monitoring and for firmware updates. StorageReview, Kevin OBrien, October 2022
- DELTA ProReviewer At 99 lb and over two feet long, the reviewer says portable must be taken with a grain of salt. Android Central, Chris Wedel, January 2022
