Anker SOLIX sells two big LiFePO4 power stations that look like close neighbors on paper: the F2600 with 2,560Wh and 2,400W, and the newer F3000 with 3,072Wh and 3,600W, according to Anker’s product pages, the F2600 data sheet (model A1781) and the F3000 user guide (model A1782). The gap is bigger than the 512Wh difference suggests. The F3000 adds a second, high-voltage solar input for 2,400W of total solar, 3,600W pass-through charging from a generator, a 30A RV outlet that can deliver its full 3,600W, and expansion to more than 12kWh. The F2600 is about 22 pounds lighter and remains a simpler, wall- and solar-charged station for camping and short outages. Here’s how they compare, spec by spec, with worked runtime and solar estimates for each.

Figures below come from Anker’s F2600 and F3000 product pages, the F2600 data sheet, the F3000 user guide and support articles, and the Amazon listings for the Anker SOLIX F2600 and Anker SOLIX F3000. I haven’t tested either unit, so every runtime and charge time below is a labeled estimate built from the published ratings.
Quick verdict
- Choose the F3000 for home backup, RV use on a 30A shore-power cord, big solar arrays, or generator charging. It outputs 3,600W, accepts up to 2,400W of solar, and scales to 12,288Wh with three BP3000 batteries.
- Choose the F2600 if you want a large station that’s easier to move, mostly charge from the wall or a modest solar setup, and rarely run loads above 2,400W.

Capacity and real usable energy
The F3000 holds 3,072Wh, which is 512Wh, or 20%, more than the F2600’s 2,560Wh. That’s roughly an extra evening of lights, a router and a TV during an outage. Neither maker figure is the energy you get at the outlet, because the inverter and electronics take a cut. For planning, I use about 85% of rated capacity for AC loads, which gives roughly 2,176Wh usable from the F2600 and 2,611Wh from the F3000. Those are estimates, not Anker numbers.
Anker’s own example for the F3000 is a 190W-rated refrigerator running for 42 hours. That works because a fridge compressor cycles on and off, so its average draw is far below its nameplate. Anker also lists 125 hours of AC idle standby, which reflects the low self-consumption it advertises for this model.
Worked runtime estimates
| Appliance (typical draw) | F2600 estimate* | F3000 estimate* |
|---|---|---|
| CPAP without humidifier, 40W | ≈ 54 hr | ≈ 65 hr |
| Wi-Fi router + modem + laptop, 80W | ≈ 27 hr | ≈ 33 hr |
| Full-size fridge, about 60W average | ≈ 36 hr | ≈ 43 hr |
| Gas furnace blower, 400W | ≈ 5.4 hr | ≈ 6.5 hr |
| Window AC, 500W running | ≈ 4.4 hr | ≈ 5.2 hr |
| Sump pump, 800W running | ≈ 2.7 hr of pump run time | ≈ 3.3 hr of pump run time |
| Microwave, 1,000W | ≈ 2.2 hr | ≈ 2.6 hr |
| Space heater, 1,500W | ≈ 1.4 hr | ≈ 1.7 hr |
*Estimate: rated Wh × 0.85 ÷ load. Example for the F3000 and a 500W window AC: 3,072 × 0.85 ÷ 500 ≈ 5.2 hours. A sump pump only runs when the pit fills, so 2.7 to 3.3 hours of actual pump time can stretch across a long storm. Check your own appliance labels; my guide on how many watts a refrigerator uses shows how to find the real number.
Output: 2,400W vs 3,600W
This is the difference most buyers notice first. The F2600 runs up to 2,400W continuously, with 2,800W of surge listed on Anker’s product page. That covers a microwave, a coffee maker or a 1,500W space heater, but not two big heating loads at once.
The F3000 delivers 3,600W in total. Each of its four NEMA 5-20R outlets can supply up to 2,400W, and the TT-30R outlet can deliver the full 3,600W on its own. Anker lists 7,200W of surge and a SurgePad mode rated 4,860W. Large motors such as well pumps and some air compressors pull a short starting spike, so the bigger surge headroom matters there. My explainer on surge watts vs running watts walks through how to size for that.
Both stations output 120V only. The F3000 can reach 240V, but only by pairing two units through Anker’s Double Voltage Hub, which then offers NEMA L14-30R and 6-20 outlets and up to 7,200W, according to Anker support.
The TT-30 outlet for RVs
Both models have a TT-30 outlet, the standard plug for 30A RV shore power. On the F2600 it shares the 2,400W limit. On the F3000 it’s rated 120V/30A and 3,600W, which is close to what a 30A pedestal supplies. If you plan to plug a travel trailer straight into the station, the F3000 gives you far more room before the rooftop AC and microwave run into each other.
Charging from the wall and a generator
The F2600 accepts up to 1,440W from a wall outlet. Anker’s data sheet estimates a full charge in about 2.2 hours at that rate, and the Amazon listing says 80% in 1 hour 40 minutes with HyperFlash.
The F3000 uses a single AC input/output port with different cables. With the standard charging cable it draws up to 1,800W (12A continuous), and Anker’s guide notes that currents above 12A are limited to under three hours. With the optional TT-30 charging cable or EV charging adapter it can draw up to 3,600W. Anker says that pairing with a 120V generator at 3,600W cuts generator run time to about 1 hour 18 minutes for a full recharge. With a BP3000 expansion battery attached, combined AC and solar input can reach 6,000W.
CleanTechnica’s hands-on review points out that pulling 1,800W continuously is best done on a 20A circuit rather than a standard 15A outlet. That’s a sensible caution for any station that charges this fast.
Solar charging: 1,000W vs 2,400W
The F2600 has one solar port rated 11–60V, up to 1,000W. Its current limit changes with voltage: 10A between 11V and 32V and 20A between 32V and 60V. That means low-voltage panels wired in parallel won’t reach the full 1,000W; you need series strings above 32V to get the 20A rating.
The F3000 has two ports. The High-PV input takes 11–165V at up to 17A and 1,600W, enough for four 400W panels in series, per Anker. The Low-PV input takes 11–60V at up to 17A and 800W, for example two 400W panels in parallel. Used together, that’s 2,400W.
| Solar array | F2600 full-charge estimate* | F3000 full-charge estimate* |
|---|---|---|
| 400W (about 280W real) | ≈ 9.1 hr | ≈ 11 hr |
| 800W (about 560W real) | ≈ 4.6 hr | ≈ 5.5 hr |
| 1,200W (about 840W real) | ≈ 3.0 hr | ≈ 3.7 hr |
| 2,400W (about 1,680W real) | Capped at 1,000W: ≈ 2.6 hr | ≈ 1.8 hr |
*Estimates assume panels deliver about 70% of their rating in good sun. Hours = rated Wh ÷ real watts. Anker’s own best-case figures are 2.9 hours at a full 1,000W for the F2600 and about 1.5 hours with 2,400W for the F3000. On small arrays the F2600 refills faster simply because it has less to fill; the F3000 pulls ahead once you go beyond 1,000W of panels. If you’re new to how the built-in controller handles voltage, my MPPT vs PWM guide explains it.
Expansion and whole-home use
The F2600 adds one Anker SOLIX 760 Expansion Battery for a maximum of 4,608Wh. The F3000 takes up to three BP3000 batteries, each 3,072Wh and 55.1 lb, for a maximum of 12,288Wh per unit. Anker’s “expandable to 24kWh” claim refers to two fully expanded F3000s working together.
| Setup | Total capacity | Usable estimate (85%) |
|---|---|---|
| F2600 alone | 2,560Wh | ≈ 2,176Wh |
| F2600 + 760 Expansion Battery | 4,608Wh | ≈ 3,917Wh |
| F3000 alone | 3,072Wh | ≈ 2,611Wh |
| F3000 + 1 BP3000 | 6,144Wh | ≈ 5,222Wh |
| F3000 + 3 BP3000 | 12,288Wh | ≈ 10,445Wh |
The F3000 also works with Anker’s Bi-Directional Inlet Box and smart meter. In that home setup, output through the inlet box is limited to 1,800W, and Anker lists four modes: Self-Consumption, Time-of-Use, Manual Backup and Storm Guard. You can also feed a 120V transfer switch from the TT-30 port, which Anker covers in its “How does F3000 work” support article. Any connection to a home panel should go through a licensed electrician; my article on transfer switches vs interlock kits explains the options.
Size, weight and moving them around
At 69.7 lb and 20.7 × 15.5 × 9.8 inches, the F2600 is the more manageable unit for loading into a truck bed or carrying to a campsite with a second person. The F3000 weighs 91.5 lb and measures 25.6 × 11.8 × 14.8 inches. Its user guide shows wheels, a pull rod and a handle, so it rolls like a suitcase over garage floors and driveways, but lifting it into a vehicle is a two-person job.
How the F3000 compares with a close rival
The EcoFlow DELTA 3 Ultra Plus is the closest match to the F3000 on paper, according to EcoFlow’s published specs: 3,072Wh of LFP capacity, 3,600W of AC output with 7,200W surge, four 20A outlets plus a 30A outlet, 1,800W AC charging and up to 1,600W of solar. The F3000’s main edges are the extra 800W of solar from its second input and 3,600W charging through the TT-30 cable. EcoFlow lists a faster UPS switchover, under 10 ms. If you need true 240V from one box, Anker’s larger SOLIX F3800 is the model to look at instead.
Setup basics from the manuals
- Charge to full before first use and pair the unit with the Anker app (the F2600 over Wi-Fi or Bluetooth; the F3000 via its IoT button).
- Turn on the AC outlet button before plugging in loads. The F3000 has a separate overload protection button near the outlets.
- Wire solar to the right port. On the F3000, series strings above 60V must go to the High-PV port; keep each string under 165V open-circuit. On the F2600, keep open-circuit voltage under 60V.
- Set charge limits and power-saving. Anker’s F2600 FAQ notes that leaving AC and car outputs on wastes energy through no-load draw, so turn them off or enable Power Saving mode when idle.
- For generator charging on the F3000, set the generator’s rating in the Anker app so the station doesn’t pull more than the generator can supply.
Who should buy which
| You are… | Better fit | Why |
|---|---|---|
| A homeowner planning for multi-day outages | F3000 | Expands to 12,288Wh, generator pass-through at 3,600W |
| An RV owner with a 30A rig | F3000 | TT-30R delivers the full 3,600W |
| Someone with 1,200W+ of solar | F3000 | Two inputs, 2,400W total |
| A camper or tailgater | F2600 | 22 lb lighter and plenty for 2,400W loads |
| A remote worker with several USB-C devices | F2600 | Three 100W USB-C ports vs two |
FAQ
Is the F3000 the replacement for the F2600?
Anker sells both. The F3000 is the newer, larger design aimed at home backup, while the F2600 is the model Anker’s Amazon listings also call the PowerHouse 767.
Can the F2600 run a 30A RV?
It has a TT-30 outlet, but it shares the 2,400W limit, so you’d run lights, outlets and the fridge comfortably and need to avoid running a rooftop AC and microwave together.
Can either one produce 240V?
Not on its own. Two F3000 units connected through the Double Voltage Hub provide 240V at up to 7,200W, according to Anker. The F2600 has no 240V option.
What solar panels work with the F2600?
Anker’s FAQ lists its 100W, 200W and 400W panels. Third-party panels work too as long as open-circuit voltage stays within 11–60V and you account for the 10A limit below 32V.
How fast does the F3000 charge from a generator?
Up to 3,600W through the TT-30 charging cable; Anker quotes about 1 hour 18 minutes of generator time for a full charge.
How long will the F3000 run a refrigerator?
Anker says about 42 hours for a 190W-rated fridge. My estimate for a typical 60W-average fridge is about 43 hours, so the two figures line up.
Can I use either as a UPS for a computer?
Both list a switchover under 20 ms, which suits most PCs, routers and network gear. Very sensitive equipment may need a dedicated UPS.
Which one lasts longer over the years?
Anker rates the F3000 at 4,000 cycles and the F2600 at 3,000 cycles to 80% capacity. Both are LiFePO4, and Anker advertises a 10-year design life for the F2600.
Bottom line
The F2600 is a large, straightforward station: 2,560Wh, 2,400W, 1,000W of solar and one optional expansion battery, in a body that’s 22 pounds lighter than the F3000. The F3000 is closer to a portable home battery, with 3,600W output, a full-power TT-30R outlet, 2,400W of dual-voltage solar, 3,600W generator charging and room for more than 12kWh. If you want to back up a house or a 30A RV, the F3000 is the stronger fit. For camping trips and shorter outages on wall or modest solar charging, the F2600 still covers the job.
