Anker SOLIX F3800 Plus

On one charge the Anker SOLIX F3800 Plus runs a typical refrigerator about 27 hours, and runs an older furnace blower about 15 hours.

Buy it if you want 3,840 Wh with 120 V and 240 V for home backup, room to grow (up to 6 extra batteries, 26,880 Wh total capacity), up to 3,200 W of solar, or charging from a 240 V generator with Anker’s adapter.

Skip it if you only need a fridge, Wi-Fi and lights for a day, or you need to lift it into a car: it weighs 136.7 lb. What to buy instead.

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.

Planning figures: a typical refrigerator averages about 83 W; an older furnace blower averages about 182 W. Yours may use less or more; the range is in the table below. How long other power stations run a refrigerator. A furnace blower is wired in: it needs an inlet or transfer switch fitted by an electrician.

How long will the Anker SOLIX F3800 Plus run a fridge, CPAP, sump pump or furnace?

One appliance at a time, from the 3,840 Wh battery, counting the power it uses just to stay on (2,923 Wh usable at a 300 W load). Fridge figures come from ENERGY STAR’s list of certified models, plus a 20 W allowance for the power station’s own draw and doors opening. CPAP with the humidifier on is the middle of the 30–100 W a CPAP with a heated humidifier draws; humidifier off is ResMed’s own 12 V figure for an AirSense 10 on ResMed’s DC cord. A night is 8 hours. Pumps and blowers switch on and off, so their average draw is far below their running watts; the hours are hours of outage, and the range runs from one that runs often to one that rarely does. A furnace blower is wired in: it needs an inlet or transfer switch fitted by an electrician.

The range behind that

This is a 3,840Wh battery with 6,000W of output, which means it gives back about 2,923 watt-hours at a typical household load (from independent tests) and can run anything drawing up to 6,000 watts at once.

It runs indoors and makes no fumes. Of the 16 household loads we track, it can run 16 for at least part of a day. It would keep a refrigerator going for 19–35 hours, from a hard-working fridge to an efficient one.

Hours of use on one charge. Typical is the middle of our range for that appliance; the range runs from a hard-working unit to an efficient one. Short-burst loads (microwave, coffee maker, garage door) show running time at full power instead. “Starts it” means the peak output covers even a hard-starting one.

What owners report, from public threads and long-term reviews; not our own testing.

  • Two reviewers say that despite being marketed as portable, the roughly 137 lb weight makes solo carrying impractical even with wheels and handles.appleinsider.com
  • One reviewer found the TT-30R outlet marketed as 30A is actually rated 25A, which could cause issues with appliances or RVs expecting true 30A service.thesolarlab.com
  • One reviewer found the base unit alone tops out around 3,500W of combined AC and solar input; reaching the full 6,000W rate requires two expansion batteries.thesolarlab.com
  • The Plus dropped the base model's XT-60 solar connectors for MC4, so owners with existing Anker solar panels or cables need adapters.thesolarlab.com
  • One tester measured about 60 dB under heavy load but called overall operation whisper-quiet during normal use, with better battery retention than the original F3800.appleinsider.com

How we know the screen was not simply blind

Finding nothing only means something if the search could have found something. So we searched the same records for this brand and got 10 recalls. That proves the screen can see this brand, so finding nothing for this model is a real result.
