Anker portable power station: match the SOLIX size to the outage
We research products from makers' specs, manuals and safety agencies; we do not run hands-on tests. Links to Amazon may earn us a commission at no cost to you. How this works.
Quick answer
Pick by how much you need to run and for how long. The Anker SOLIX C1000 Gen 2 (1,024 Wh, 2,000 W, 24.9 lb) covers phones, lights, a router and short fridge runs. The C2000 Gen 2 (2,048 Wh, 2,400 W) adds a TT-30R RV outlet, 800 W solar input and an expansion battery. The F3000 (3,072 Wh) is a 91.5 lb wheeled unit that two can pair for 240 V. All three use LFP batteries Anker rates for 4,000 cycles and charge only between 32°F and 104°F.
Three Anker SOLIX sizes compared
| Spec | C1000 Gen 2 | C2000 Gen 2 | F3000 |
|---|---|---|---|
| Capacity | 1,024 Wh | 2,048 Wh | 3,072 Wh |
| AC output | 2,000 W (3,000 W peak) | 2,400 W (4,000 W peak) | 3,600 W |
| Max solar input | 600 W | 800 W | 2,400 W |
| Max AC charging | 1,600 W UltraFast | 1,800 W | 1,800 W |
| Expandable | No | Up to 4 kWh | Up to 24 kWh |
| UPS switchover | 10 ms | 10 ms | 20 ms |
| Weight | 24.9 lb | 18.9 kg (about 41.7 lb) | 91.5 lb |
| Rated cycles | 4,000 to 80% capacity | 4,000 to 80% capacity | 4,000 |
Capacity per pound tells you how portable each one really is. The C1000 Gen 2 stores about 41 Wh per pound (1,024 / 24.9), the C2000 Gen 2 about 49 (2,048 / 41.7) and the F3000 about 34 (3,072 / 91.5). The F3000 makes up for its weight with wheels and a pull rod.
C1000 Gen 2: the grab-and-go outage kit
Anker lists the C1000 Gen 2 at 1,024 Wh with 2,000 W of continuous AC output, a 10 ms UPS switchover and 600 W of solar input. Its UltraFast mode charges from the wall at up to 1,600 W, and Anker's comparison table lists 49 minutes to 100%.
Two limits matter. Anker says the C1000 Gen 2 is not expandable; for added battery capacity it points buyers to the original C1000. And UltraFast charging only runs at full speed when the cells are above 68°F; charging between 32°F and 68°F is significantly slower. Anker also suggests using UltraFast only when necessary to prolong battery life.
It weighs 24.9 lb and measures 15.12 x 8.19 x 9.61 inches, small enough to store in a closet and carry room to room.
C2000 Gen 2: home backup with an RV outlet
The C2000 Gen 2 doubles capacity to 2,048 Wh and raises continuous output to 2,400 W with 4,000 W peak. Its outlets include a 20 A NEMA 5-20R, a TT-30R for RV-style plugs and a bi-directional inlet-box output rated at 15 A and 1,800 W. Solar input reaches 800 W.
Anker lists an idle draw of 9 W and says it can run a dual-door fridge for up to 32 hours, or up to 64 hours with the BP2000 (Gen 2) expansion battery, which adds another 2,048 Wh at 15.3 kg. Treat those runtimes as Anker's figures for its test fridge; your appliance and room temperature will change them.
Any connection to a home circuit through an inlet box needs a properly installed transfer switch or interlock. Have a licensed electrician do that work.
F3000: wheeled capacity for longer outages
The F3000 stores 3,072 Wh in a 51.2 V LFP pack and is listed by Anker as UL 9540 certified. It accepts up to 2,400 W of solar through two inputs and charges at up to 1,800 W from the wall. Anker says pairing two units provides 240 V for high-demand appliances and that the system expands to 24 kWh with BP3000 batteries, each 3,072 Wh and 55.12 lb.
At 91.5 lb and 25.6 x 11.8 x 14.8 inches, it is a roll-into-place unit rather than a carry-along. Its UPS switchover is 20 ms, slower than the C-series 10 ms. Anker also sells a generator input adapter for charging it from a fuel generator; the generator itself must run outdoors only.
Use and charge it safely
- Charging temperature. All three list 32°F to 104°F for charging; the C1000 Gen 2 and F3000 list -4°F to 104°F for discharging. Keep them indoors in winter outages.
- Size to the load. Add up the running watts of everything you will plug in at once and stay under the continuous rating, not the peak.
- Generators stay outside. If you recharge from a gas generator, keep the generator outdoors and far from openings; the power station can stay inside.
- Home wiring. Never backfeed a house through an outlet. Use the maker's approved transfer equipment installed by an electrician.

- Which Anker power station is best for a power outage?
- It depends on your loads. The C1000 Gen 2 suits small essentials, the C2000 Gen 2 suits a fridge and RV-style loads with expansion, and the F3000 suits longer outages and larger solar setups.
- Can Anker SOLIX power stations be expanded?
- The C2000 Gen 2 expands to 4 kWh with a BP2000 (Gen 2) battery and the F3000 to 24 kWh with BP3000 batteries. Anker says the C1000 Gen 2 is not expandable.
- Can I charge an Anker power station in the cold?
- Anker lists a 32°F to 104°F charging range for all three models. The C1000 Gen 2's fastest charging needs cells above 68°F.
- How long will an Anker power station run a fridge?
- Anker says the C2000 Gen 2 can run a dual-door fridge up to 32 hours, or 64 hours with an expansion battery. Real runtime depends on your fridge's draw and how often it cycles.
