Anker SOLIX F3800 Review: Key Specifications
Numbers matter. Marketing does not. Here are the specs that determine whether this unit protects your home.
| Specification | Anker SOLIX F3800 | Why It Matters |
|---|---|---|
| Capacity | 3840Wh | Powers essentials 2-3 days |
| Continuous Output | 3200W | Runs heavy appliances |
| Peak Output | 6000W | Handles motor startup surges |
| Solar Input | 2400W max | Fastest recharge in class |
| Battery Type | LiFePO4 | 3000+ cycles. Safer chemistry. |
| AC Outlets | 6 x 120V | Multiple devices at once |
| Weight | 132 lbs | Wheels included |
| Warranty | 5 years | Longest in this price class |
LiFePO4 chemistry matters here. The U.S. Department of Energy confirms it offers superior thermal stability. No thermal runaway risk. The 3000+ cycle rating means daily use for eight years before major capacity loss.
Compare this against cheaper lithium-ion units. Those last 500-800 cycles. Do that math before choosing price over longevity. Our Component Selection Guide breaks down battery chemistry in detail.
Anker SOLIX F3800 Review: Real-World Performance
Lab specs tell one story. Actual use tells another. Here is what the F3800 handles based on reported loads and capacity math.
Storm Scenario: 48-Hour Outage
Grid down two days. The F3800 keeps running:
- Refrigerator: 48 hours. Zero food loss.
- Wi-Fi router: Full internet the entire time.
- LED lighting: Every room. Every evening.
- Phone and laptop charging: All devices topped off.
- Remaining capacity: Roughly 18% after 48 hours of combined loads.
Cold Weather Scenario: Extended Winter Outage
January. Fifteen degrees. Grid gone three days. The F3800 supports:
- Space heater (1500W): 2.5-hour sessions per room.
- Well pump: Water throughout. No interruption.
- CPAP machine: Ran overnight. Every night.
- Electric blankets: Warm sleep. No complaints.
Workshop Scenario: Daily Job Site Use
Beyond emergencies. The F3800 handles regular power tool loads.
- Circular saw (1800W): Two hours continuous.
- Air compressor (1200W): Three hours runtime.
- Table saw (2200W): 90 minutes of cuts.
Wattson's Wisdom
"Researched dozens of power stations. Most oversell and underdeliver. The F3800 specs match what users report. That fact alone puts it ahead of 90% of what is on the market."

Real numbers. Real appliances. Your results depend on efficiency and conditions.
| Appliance | Wattage | Expected Runtime |
|---|---|---|
| Refrigerator | 150W avg | 48+ hours |
| Space Heater | 1500W | 2.5 hours |
| Electric Stove | 2000W | 1.9 hours |
| Coffee Maker | 1200W | 20+ cycles |
| Wi-Fi Router | 20W | 192+ hours |
| LED Lights (5) | 50W total | 76+ hours |
| CPAP Machine | 60W | 64 hours |
| Circular Saw | 1800W | 2.1 hours |
What It Will Not Run
Honesty builds trust. The F3800 struggles with:
- Central AC: Draws 3000-5000W. Impractical.
- Electric water heater: 4500W. Exceeds output.
- Multiple heavy loads at once: Choose wisely.
For central AC, pair this with a dual-fuel generator. For sizing your total system, our System Design Guide walks through load calculations.
Anker SOLIX F3800 Review: Solar Charging
The 2400W solar input separates this unit. Here is what that means on your rooftop or in your yard.
| Conditions | Solar Input | 0-80% Charge |
|---|---|---|
| Full Sun (1200W panels) | 1100-1200W | 3.5 hours |
| Partly Cloudy | 600-800W | 5-6 hours |
| Overcast | 300-400W | 8-10 hours |
| Light Rain | 200-300W | 12+ hours |
The included 400W panel is a starting point. Expand to 1200W+ for real independence. Quality monocrystalline solar panels pair well with this unit.
NREL data shows most U.S. locations average 4-6 peak sun hours daily. Enough for full recharge with adequate panels. Our Beginner's Guide to Off-Grid Solar covers panel sizing basics.

How long will the Anker SOLIX F3800 power a refrigerator?
48+ hours. The F3800 powers a standard fridge drawing 150W average for two full days. Runtime varies by fridge efficiency and room temperature.
Can the Anker SOLIX F3800 run a well pump?
Yes. The F3800 handles 1HP well pumps at roughly 1200W without issues. Check your pump startup surge stays under the 6000W peak rating.
How fast does the F3800 charge with solar?
With 1200W of panels in full sun, expect 80% charge in 3.5 hours. It accepts up to 2400W solar input for even faster recharge times.
Is the Anker SOLIX F3800 worth the price?
Yes, for whole-house backup. The 3840Wh capacity, LiFePO4 battery lasting 3000+ cycles, and five-year warranty justify the cost over cheaper alternatives that fail in two years.
How does the F3800 compare to EcoFlow Delta Pro?
The F3800 wins on solar input (2400W vs 1600W) and warranty (five years vs four). The Delta Pro delivers higher continuous output at 3600W vs 3200W. Both use LiFePO4 batteries.
Will the F3800 run central air conditioning?
No. Central AC draws 3000-5000W. The F3800 maxes at 3200W continuous. Window units under 1500W work fine. For whole-house AC, pair with a dual-fuel generator.
What battery chemistry does the F3800 use?
LiFePO4. Lithium iron phosphate. It offers superior thermal stability, 3000+ charge cycles, and zero thermal runaway risk compared to standard lithium-ion.
Can I expand the F3800 with more batteries?
Yes. Expansion batteries add 3840Wh each. Maximum system reaches 11,520Wh with two expansion units. That is three days of whole-house essentials without solar.
How loud is the F3800 versus a gas generator?
Near silent. Under 30 decibels at full load. Gas generators average 65-75 decibels. Your neighbors will not know you have power. You will.
Does the F3800 work in freezing temperatures?
Yes, with reduced performance. LiFePO4 discharges safely to -4°F. Charging requires above 32°F. Users report normal discharge at 15°F during winter storms.
How heavy is the F3800?
132 pounds. Wheels included. Two people can load it into a truck bed. This unit stays at your homestead. Not a hiking companion.
Can I use the F3800 while it charges from solar?
Yes. Pass-through charging works simultaneously. Solar feeds the battery while you draw power. Net charge rate equals solar input minus your current load.
Final Verdict: Anker SOLIX F3800 Review
After deep research, the verdict is clear. The F3800 delivers.
3840Wh powers your essentials for two to three days. 3200W runs the fridge, the heater, and the power tools. 2400W solar input means real independence. Not just backup.
At $3,500-4,000, it costs real money. So does $800 in spoiled food. So do three nights in a hotel. So does lost work. Add those up across five years of storms.
The five-year warranty matters. The 3000+ cycle battery matters. Your gas generator cannot match either claim.
Rating: 4.7/5. Best whole-house power station under $4,000 for solar-first energy sovereignty.

Wattson's Wisdom
"The question is not whether $4,000 is a lot. The question is what the next blackout costs you. Spoiled food. Lost wages. A scared family in a dark house. Do that math. Then decide."
For the homesteader who stops worrying when the forecast shows ice. Because the backup is already in place.
For the father whose kids never know the power went out. Because 3840 watt-hours kicked in before they woke up.
For the patriot ready to break free from grid dependency. Not with talk. With quiet, solar-charged independence. This is your path forward.
