F3800 or F3800 Plus?
Most people: the F3800. On October 3, 2026 it cost $1,980 on Amazon, $420 less than the Plus ($2,400). Same battery, same 6,000 W, same BP3800 packs (Anker). That is $607 per usable kWh against $735.
Buy the Plus if you will charge from a gas generator or a 240 V outlet, or fill a big solar array. The Plus takes 3,200 W of solar at 11–165 V (Anker) and charges from a 240 V generator with Anker’s adapter (Anker; Anker). F3800 Plus on Amazon.

From Anker’s table comparing the two and the Plus page. The Plus generator rate is 3,300 W alone and 6,000 W with a pack (Anker). The Plus weighs 136.7 lb (Anker). More on the two.
F3800 or EcoFlow DELTA Pro 3?
Most people: the F3800. $1,980 against $2,799 for the EcoFlow DELTA Pro 3 on October 3, 2026: $607 per usable kWh against $804. It gives 6,000 W to the DELTA Pro 3’s 4,000 W, and takes 6 extra batteries to its 2.
Buy the DELTA Pro 3 if you want a bit more battery in one box (4,096 Wh against 3,840) and less weight (113.5 lb against 132.3 lb). Both, with the Jackery 5000 Plus.
Extra batteries: what each BP3800 buys
The Anker SOLIX BP3800 Expansion Battery adds 3,840 Wh. Up to 6 fit the F3800 or the Plus (Anker; Anker), for 26,880 Wh (Anker guide). On October 3, 2026 one cost $1,800 on Amazon: $551 per usable kWh. Our home-backup guide picks the F3800 with 2 packs for a fridge and furnace through a day ($5,580 in all). Amazon also sells the F3800 with one BP3800 for $3,579, $201 less than buying both apart ($3,780).
The same numbers as a table
| Setup | Wh | Fridge + furnace + essentials | Amazon | Per usable kWh |
|---|---|---|---|---|
| F3800 alone | 3,840 | 10 hours | $1,980 | $607 |
| F3800 + 1 | 7,680 | 21 hours | $3,780 | $579 |
| F3800 + 2 | 11,520 | 31 hours | $5,580 | $570 |

| F3800 + 6 | 26,880 | 73 hours (3 days) | $12,780 | $559 |
Each pack weighs 72.8 lb (Anker) and cannot be used alone (Anker). The Solar Lab found their cables long and floppy (The Solar Lab). Two F3800s on Anker’s Double Power Hub give 12 kW and up to 53.8 kWh (Anker hub guide; Anker).
How long it runs each appliance
A typical fridge runs about 39 hours: 9.3 for an old one working hard, up to 163 for an efficient one. Fridge, Wi-Fi, lights and phones, no furnace: about 25 hours.
An older furnace blower runs about 18 hours and a variable-speed one longer. It starts even a hard-starting blower. For a furnace alone, our furnace guide picks the smaller EcoFlow DELTA 2 Max with 1 extra battery ($1,928): it costs less. The F3800 is for an older blower or a longer night.
A sump pump runs about 24 hours, and it starts even a hard-starting pump (sump pump picks). A 240 V well pump: it starts even a hard-starting one, through a transfer switch. Central air: TechRadar’s Collin Probst uses two F3800s, 12 kW, for his AC (TechRadar).

How it connects to your house
Anker SOLIX Home Power Panel. The F3800 connects to it to power your house (Anker guide), through a Home Panel port rated 6,000 W out and 3,800 W in (Anker guide). Anker offers an installation service (Anker). It cost $1,099 at Amazon (checked October 3, 2026).
A transfer switch. The L14-30 and 14-50 outlets give 120/240 V, up to 6,000 W (Anker guide), so a generator inlet and transfer switch work. Anker sells it with a 10-circuit manual transfer switch (Anker). On Amazon the F3800 with a transfer kit cost $2,529 on October 3, 2026, $549 more than the F3800 alone. Which transfer switch fits.
An electrician installs either one, with neutral and ground wired (Anker guide). While it charges from a 120 V outlet, the 240 V outlets are off (Anker). Never plug a power station into a wall outlet to feed the house. All ways to connect.
Questions buyers ask
How much solar can it take?
Up to 2,400 W: two inputs of 1,200 W (Anker). Each input takes 11–60 V (Anker); over 60 V damages it (Anker guide). Anker says full in under 2 hours in strong sun (Anker). The Solar Lab could barely reach 1,600 W (The Solar Lab). Which panels fit.
Can it work as a UPS?
Yes, on the left three 120 V outlets (Anker guide). It switches in 20 ms (Anker guide). In UPS mode the 240 V outlets do not work (Anker).
How heavy is it? Can I move it?
132.3 lb (Anker), 27.6 x 15.3 x 15.6 in (Anker guide). It rolls on wheels; to lift it, use the top and bottom handles (Anker guide). TechRadar found stairs and loading a car hard (TechRadar).
More questions: wall charging, electric cars, cold, storage, warranty, ports, manual
How fast does it charge from the wall?
1,800 W from a 120 V outlet (Anker guide), the same as the Plus. The Solar Lab says it can also take solar and the wall at the same time (The Solar Lab). It charges only from a 12 V car socket (Anker guide).
Can it charge an electric car?
Yes, from the 14-50 outlet in EV mode (Anker). Set the car’s charger under 25 A (Anker guide). One charge adds only 3.84 kWh.
Can it run in the cold?
It runs from −4°F to 104°F (Anker guide) but charges only from 32°F to 104°F (Anker guide).
How do I store it?
Check it each week and charge it full if it drops below 30% (Anker guide). Charge it to 100% every 3 months (Anker guide). It turns off after 12 hours with the outputs off and no load (Anker guide).
What is the warranty?
Five years (Anker). The LFP battery is rated for 3,000+ cycles (Anker), to at least 80% (Anker).
What ports does it have?
Six 120 V 20 A outlets, plus a 14-50 and an L14-30 at 120/240 V (Anker). Each group of three 120 V outlets gives 2,400 W (Anker guide). Three USB-C at 100 W each (Anker), output only (Anker guide). The light is switched in the app (Anker guide).
Where is the manual?
Anker’s US user guide is a PDF: F3800 user guide. Firmware updates run through the Anker app.
What testers found
We do not test units ourselves. These testers did.
- The Solar Lab ran office loads and a kitchen load of about 3,200 W; it hardly made noise (review). The fans run 50–60 dB when on (review) and kick in and out (review). The light is no brighter than a nightlight (review). It is the heaviest single unit they have tested (review).
- When TechRadar’s Collin Probst (review) tried to charge another big power station from it, it warned of a risk of damage (review). A year later an electrician put in Anker’s panel for his two F3800s (review).
