Our Review
A 2560Wh LiFePO4 workhorse with 2,400W output and a 75-minute recharge — the sweet spot between the C1000's portability and the F3000's whole-home ambitions, if you can find it in stock.
Specifications
| Capacity | 2560 Wh |
|---|---|
| Continuous output | 2400 W |
| Surge output | 3600 W |
| Battery chemistry | LiFePO4 |
| Cycle life (to 80%) | 3000 cycles |
| AC recharge | 75 min |
| Max solar input | 1000 W |
| Weight | 67.2 lbs |
The SOLIX F2600 is Anker's mid-tier heavyweight: 2560Wh of LiFePO4 capacity behind 2,400W continuous output (3,600W surge). That combination matters — 2,400W starts refrigerators, microwaves, sump pumps, and most power tools without drama, and 2.5kWh of capacity means you're measuring runtime in days rather than hours. For the wattage math behind those startup loads, see Surge Watts vs Running Watts.
Charging is a strength across the board: about 75 minutes from the wall, and up to 1,000W of solar input — enough to refill the entire pack in a good solar day with panels to match (why real-world harvest runs below sticker rating: our charging guide). The 3,000-cycle battery is the long-life chemistry we recommend for anything this size (LiFePO4 vs NMC).
The tradeoff is mass. At 67.2 lbs this is not a grab-and-go unit — it lives in a van, garage, or basement and moves by cart or with a partner.
Pros
- 2560Wh + 2,400W covers nearly every household load
- 3,000-cycle LiFePO4 for a decade of regular use
- ~75-minute wall recharge
- 1,000W solar input — full refill in one sunny day
Cons
- 67.2 lbs — plan where it lives, not where you'll carry it
- Not currently stocked at our tracked retailers
What it actually runs
A full 2560Wh charge yields about 2,175Wh usable:
| Device | Typical draw | Runtime per charge |
|---|---|---|
| Full-size fridge | ~65W avg | ~33 hours |
| CPAP (humidifier on) | 60W | ~36 hours (4.5 nights) |
| Microwave | 1,000W | ~2 hours of run time |
| Space heater (low) | 750W | ~2.9 hours |
| Laptop + lights + phones | ~80W | ~27 hours |
Can the Anker SOLIX F2600 back up a refrigerator during an outage?
Yes, comfortably. 2,400W handles any residential fridge's compressor start, and the 2560Wh pack keeps a typical full-size fridge cycling for around 33 hours — longer if you open it sparingly. For whole-outage planning, see our guide to using a power station as a UPS.
How does the F2600 differ from the F3000?
The F3000 adds capacity, higher output, and expansion options for whole-home ambitions; the F2600 keeps the same 3,000-cycle LiFePO4 chemistry in a smaller, cheaper package. If you're powering a van or covering outages under a day, the F2600 is the right size.
Who it's for: van lifers and outage-prone households that need multi-day runtime and real appliance wattage, and have a fixed spot for 67 lbs of battery. If you can't find one in stock, the in-stock alternatives bracket it from both sides: the Anker SOLIX F3000 (currently $1399.00) above, and the SOLIX C1000 Gen 2 (currently $499.98) below if portability matters more than capacity.
