Anker SOLIX F3800
On one charge the Anker SOLIX F3800 runs a typical fridge about 23 hours and an older furnace blower about 14 hours.
It is a 3,840 Wh power station on wheels with 6,000 W at 120 V and 240 V. Both, plus Wi-Fi, lights and phones: about 9 hours.
Amazon had no offer for this model on its own when we checked on November 1, 2026.
Buy this instead: EcoFlow DELTA Pro 3, $2,799. It holds at least as much (4,096 Wh) with 120 V and 240 V outlets, and Amazon sells it today. It puts out less: 4,000 W against 6,000 W.

Looking at the F3800 Plus? The F3800 Plus page. Which one to buy. We compile maker specs and published tests; we did not test this unit.
What independent tests measured
- Usable energy: 2,905–3,145 Wh (median 3,025) in 2 tests at loads of 260 W or more (The Solar Lab, Notebookcheck).
- Power it uses just to stay on: 36–73.6 W with the AC outlets on and nothing plugged in (The Solar Lab, Jasonoid (YouTube)).
- What we use: 2,798 Wh usable at a typical 300 W load; every hours figure on this page counts the idle draw. The one rule we use.
F3800 or F3800 Plus?
They share the battery, the output and the BP3800 packs. The Plus adds solar input and generator charging. Compare prices on the day you buy.

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.
How long it runs each appliance
A typical fridge runs about 23 hours: 17 for an old one working hard, up to 28 for an efficient one. Fridge, Wi-Fi, lights and phones, no furnace: about 17 hours.
An older furnace blower runs about 14 hours and a variable-speed one longer. It starts even a hard-starting blower. For a furnace alone, our furnace guide picks the EcoFlow DELTA Pro 3 ($2,799): it costs less. The F3800 is for an older blower or a longer night.
A sump pump runs about 17 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).

Typical is the middle of our range for that appliance. The range runs from a hard-working unit to an efficient one. Microwave, coffee maker and garage door show minutes of running time, because they run in short bursts.
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).
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). 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).

Recall check: no CPSC recall names the F3800 (model A1790) in our screen of October 9, 2026. That cannot clear your own unit. Check the model and serial number on its label with Anker (Anker recall lookup) or the CPSC recall search.
